Pandagon disturbs me


Sometimes, men really suck. Amanda horrifies me with this wife-beating video: a horrible little man browbeats, strikes, and briefly chokes his wife while having their children videotape the whole thing. I guess he felt that she deserved it.

I couldn’t help but noticed that the wretched Y-chromosome-bearing thug was also prominently wearing a bright, sparkly cross around his neck the whole time.

As if one shaming wasn’t enough, Amanda also had to flaunt another example of male stupidity, a ghastly speech arguing that gender differences justify inequities — it goes on at length about the tiresome argument that the statistical distributions skew with men having more outliers at both ends than women. Here’s a good argument against that:

His first attempt to argue that men are smarter than women is the strange “men are at more extremes of the IQ spectrum than women”. As Violet notes, this is a pretty weak argument, since the extremes of the range are statistically insignificant and not really the drivers of society. And since women are in fact as smart as men, the initial “men are on top because they’re just smarter LARRYSUMMERSWASAVICTIM” argument falls apart pretty quickly.

If there’s one lesson we should have learned from the Bush years, it is that the best and brightest do not necessarily rise to the top, so it’s awfully silly to argue that there is a meritocracy in operation that is merely rewarding the slender tail at the far right of the distribution.

There’s also an unwarranted assumption there. Why assume that the dregs to the left of the distribution must be compensated for by paragons to the right? We already know that women experience a cultural wall that limits their ability to excel at the most remunerative endeavors — it seems to me that it’s just as reasonable to estimate that female performance at the high end of the scale might be equivalent to male’s; I can see where hemizygosity might lead to a greater frequency of aberrant pathologies, but not where it would lead to particular advantages in this situation.

But most of all what bugs me about the stupid speech is that it begins by deploring the idea of a “battle of the sexes”, and then justifies many of its excuses with evolution, as if men and women are separately evolving species. It’s absurd. Over half my genes come from my mother, and a slightly fewer come from my father. We evolve together, with an obligate mingling of alleles from both sexes at every generation. We both have equal potential, because it is the same potential — the only question is whether we’re going to let bogus apologetics for inequities continue to limit the possibilities for half of us.

    I’ve often wondered if the reason that boys are now lagging girls in education is because there is more equality between the sexes in education. I have to laugh when I hear conservatives blame the system because boys are underperforming: “boys are more active and can’t sit for long periods”; “most teachers are women who have it in for boys”; etc. The same conditions existed when boys outperformed girls, but now it’s a “crisis.” Ah, well . . .

    If abuse is a learned behavior, which I believe it to be, I want to know what sort of follow-up treatment is being given to the children who were daily witnesses to this. How are they being treated to understand that their father’s behavior was not normal?

    Domestic abuse is a terrifying social crime, an artifact that continues because we still haven’t figured out how to break the cycle from generation to generation.

    Now I wouldn’t advocate violent retribution, but I will say that I did recently purchase two new Filipino swords and the phone book I’ve been test-cutting them on suddenly feels strangely inadequate.

    They showed that video in my police academy. I don’t think I’ve seen 16 more angry people in a room after watching a video than at that time. There was actually applause when they said he got 36 years.

  5. says

    Over half my genes come from my mother, and a slightly fewer come from my father.

    Before anyone asks, I’m guessing this refers to the combined nuclear and mitochondrial genomes. (Right?)

    Still, this other part seems weird:

    But most of all what bugs me about the stupid speech is that it begins by deploring the idea of a “battle of the sexes”, and then justifies many of its excuses with evolution, as if men and women are separately evolving species.

    There is such a thing as sexual dimorphism, and there is such a thing as sexual dimorphism fueled by sexual selection. My hypothetical sister and I don’t both have the same potential to develop an attractive goatee or seductively deep Barry White voice. Is there any particular reason why That Thing IQ Measures can or can’t be one of those sexually selected dimorphisms? Or just a plain old dimorphism?

    Maybe biology is a flimsy excuse for social inequity, but maybe it’s the other way around. I don’t see conclusive arguments here for either.

  6. Azkyroth says

    I don’t think I want to watch the video, but based on what I’m hearing, I’m inclined to agree.

    I find it especially disturbing that this person (there are women who do this sort of thing, although there aren’t nearly as many of them, and they’re equally deplorable, but that’s not the point here) even had his kids watch this, let alone videotaping it. I have nothing but contempt for people who feel that behaving violently towards should-be-loved ones is acceptable, and this is speaking as a person who’s struggled with anger management issues in the past and, to a lesser degree, still does. I’ve never felt it was right or defensible when I’ve lost my temper and become violent, and on the occasions where I’ve found myself grabbing my wife’s shoulders or pushing her, I’ve explained to her later, over her protests, that it was NOT her fault, that what I did was NOT ok or justified, and that it reflected a problem with ME, not her. I’ve sought counseling before, but it hasn’t helped much; I haven’t, so far, had much luck in getting mental health professionals to talk to ME rather than to half-listen until they find the Central Casting cardboard archetype my situation and personality are least unlike and then robotically responding to that. I have never been, and scrupulously avoid, becoming drunk, in large part for this reason. Anyone who feels inclined to tell me that this is wrong is preaching to the choir, but I’m very interested in any serious, constructive suggestions anyone might have. :/

    Whenever it’s been argued that women can’t do X, where X is something men can do, it’s turned out that they can.* By now, each fresh argument that “this new X is different” ought to be even less convincing, but too many of us want to believe.

    * Because it’s obvious that in category Y, which includes child-bearing and breast-feeding, men can do fuck all.

  8. Ichthyic says

    There is such a thing as sexual dimorphism, and there is such a thing as sexual dimorphism fueled by sexual selection.

    Indeed I also felt the comment only relevant to the issue of the abuse of evolutionary theory in the realm of meta-analysis of human social issues (long history of that), but then missed the perhaps lesser point that there are indeed predicted and observable differences in selective pressures between the sexes.

    I sometimes wonder if sciencebloggers forget there’s this little thing called:

    Parental investment theory.

    was formalized by Trivers…

    remember now?

    sure, we evolve together, but that doesn’t mean each sex doesn’t have a different set of selective pressures.

    However, it’s all a side issue of the key one here anyway, which is simply:

    the guy in the video is fubar for beating his wife, his wife and kids will need decades to recover from the mental and physical abuse, and aberrations like that aren’t necessarily best explained by generalized evolutionary theory of any kind, but fit better into the realm of practical pyschology.

    I rather think it might be a good idea to post links to websites that talk about the development of abusive behavior, and examine treatment options, so that those who actually might be experiencing something similar might get a start on what can be done.

    like this for example:

    http://www.abusedadultresourcecenter.com/index.htm

    http://www.helpguide.org/mental/domestic_violence_abuse_types_signs_causes_effects.htm

    the issue of domestic violence is perhaps a far more important issue to discuss than the merits of the application of sociobiology.

    I’m also reminded of Mill’s commentary, still appallingly relevant to the present understanding of gender differences:

    Neither does it avail anything to say that the nature of the two sexes adapts them to their present functions and position, and renders these appropriate to them. Standing on the ground of common sense and the constitution of the human mind, I deny that anyone knows, or can know, the nature of the two sexes, as long as they have only been seen in their present relation to one another. If men had ever been found in society without women, or women without men, or if there had been a society of men and women in which the women were not under the control of the men, something might have been positively known about the mental and moral differences which may be inherent in the nature of each. What is now called the nature of women is an eminently artificial thing — the result of forced repression in some directions, unnatural stimulation in others. It may be asserted without scruple, that no other class of dependents have had their character so entirely distorted from its natural proportions by their relation with their masters; for, if conquered and slave races have been, in some respects, more forcibly repressed, whatever in them has not been crushed down by an iron heel has generally been let alone, and if left with any liberty of development, it has developed itself according to its own laws; but in the case of women, a hot-house and stove cultivation has always been carried on of some of the capabilities of their nature, for the benefit and pleasure of their masters Then, because certain products of the general vital force sprout luxuriantly and reach a great development in this heated atmosphere and under this active nurture and watering, while other shoots from the same root, which are left outside in the wintry air, with ice purposely heaped all round them, have a stunted growth, and some are burnt off with fire and disappear; men, with that inability to recognise their own work which distinguishes the unanalytic mind, indolently believe that the tree grows of itself in the way they have made it grow, and that it would die if one half of it were not kept in a vapour bath and the other half in the snow.

    Icthyic: thanks for the links, I’ll take a look.

    Why does this remind me of the “Recital”?
    Oh, perhaps things like these:
    4:24 And all married women (are forbidden unto you) save those (captives) whom your right hands possess.
    4:34 Men are in charge of women, because Allah hath made the one of them to excel the other, and because they spend of their property (for the support of women). So good women are the obedient, guarding in secret that which Allah hath guarded. As for those from whom ye fear rebellion, admonish them and banish them to beds apart, and scourge them. Then if they obey you, seek not a way against them. Lo! Allah is ever High, Exalted, Great.

    On the suggestion side for that, I doubt there’s anything you can do to get the psychobabble people to do their jobs properly since I don’t believe they are competent to do them anyway. I suppose you could go through an exhaustive search for the one exception to the rule but that would almost certainly cost a lot of money.

    On the suggestion side for the actual problem: do you at least know what your triggers are? Do you go back and analyse and record what you can as soon as you’ve caught yourself in the act? Those would be the bits on which you then need to apply higher level feedback to your behaviours in the hope of eventually modifying the lower level instincts.

  12. says

    I tried watching this video but must confess I chickened out after the first 15 seconds – the expression of lost, hopeless, helpless despair on that woman’s face was too much to bear.

    The thought that that sickening piece of filth had his kids watch this makes me feel physically nauseous.

    Sometimes I almost wish that there really was a hell – and that the fairy in charge of who goes there was actually moral.

    yes, sad to say, the limited amount of health care resources devoted to mental health care were tiny even 30 years ago; now, I see entire mental health care depts. that were designed originally to cover whole cities or counties closing their doors completely due to lack of funding, lack of coverage from HMO’s, and the exponentially increasing health care costs.

    It’s become quite a scary thing for those suffering from any mental health issues whatosoever, with fewer and fewer places to turn for treatment.

    Imagine if you were diagnosed with a high risk of a heart attack and had no place to go to even seek treatment?

    that’s actually just the way it is now in many counties in the US wrt mental health treatment.

    HMO’s would of course, prefer the drug cos simply develop pills instead of treatment plans, and that’s exactly what we see.

    this problem is only going to get worse.

    far worse.

    I do hope that Hillary continues to pick up the pace of health care reform, now that it appears to be yet again a central issue in her campaign.

    anything would help more than letting the HMO’s continue to fuck everything up.

    at the moment, I don’t see much to get my hopes up.

    what’s even worse, is that there appears to be a social stigma against even reporting that you might be experiencing a mental illness of any kind, even though they are just as common as any other physical ailment.

    it’s like saying you have tourettes is somehow worse than saying you have gallstones.

    this too, IMO, contributes to the lack of funding for mental health care in this country, as the stigma logically carries on up to those who make funding decisions, and over time will of course influence the resources available to consumers.

    it’s like mental health care gets shotgunned by both barrels.

    :/

    helping to lift the stigma in order for people to feel more comfortable asking for help would at least be a start.

    so, kudos to Askyroth for openly talking about what he is dealing with.

    my only suggestion would be to try and find a local group therapy session to attend on a weekly basis; that might be helpful.

    as to where to find a good group therapist that deals with your specific issues. I don’t know, but maybe there is something in the links to the abuse resources (those were just the first two legit ones that came up; likely there are many more).

  14. Ichthyic says

    Sometimes I almost wish that there really was a hell

    a convicted abuser in a federal pen for 36 years?

    that would qualify as hell in most people’s books.

    so, in essence, I think your wish was granted. The hubby is very likely currently learning what it means to be abused himself.

    humans can create far worse hells than even the most creative among us can imagine.

  15. EB says

    I don’t think the world is civilized enough yet that we can readily admit that there are real differences in people on this earth, without causing problems. Nearly constant ethnic killing all over the world is a powerful reminder that many people can’t at the same time believe that two groups really can be different (even in small ways), but still treat both groups with equal respect. That said, I don’t believe the fact that so many humans are ethically challenged means we have to resist scientific research into those real differences in sexes/races, to better the human condition. Let me explain…

    Many people seem convinced that science will prove that every human subgroup is near-perfectly equivalent in basically every trait/skill. I believe all people deserve equal opportunities and treatment, but I don’t have the slightest expectation that science will prove the equivalence of every group of people (male/female, races, etc.) in every skill/trait, and I wouldn’t want to live in such a world anyway. To ensure survival of our species, we NEED subgroups with substantive differences. Some people seem largely unaffected by the HIV virus, for example. If we found out that Mediterranean people, for example, are much more likely to be resistant, would we dismiss this research as racist toward Hispanics? If not, should we consider it racist/sexist if a well-run study found that a certain race/sex seemed to be better at some types of logic games? It wouldn’t mean the difference is essential/genetic, but it is still a measurable difference.

    Though I can see faults in Roy’s speech, I think it is critical for a free-thinking individual to the admit there are differences in males and females, for example. It would be naive to assume that males and females (or races, etc.) differ only in some “practically insignificant” or only the obvious physical ways, and we don’t also differ to some extent in deeper psychological ways or ways that really do promote the fitness of one trait/skill over another. This isn’t to say that we should use these differences to enforce a hierarchy upon humans based on some arbitrary criteria and then try to justify poor treatment of some specific subgroup. But if reliable evidence suggests that Chinese people seem to excel in IQ tests more so than Caucasians, I’m perfectly willing to accept that as a statement of fact, for a given snapshot of people and a given definition of IQ. Similarly, if women tend to be more able to form close social bonds than men, that is a wonderful skill to celebrate. If men happen to excel at tests involving spatial skills, that is fine too. The specific skills involved are not critical to my point, so substitute something that doesn’t make your blood boil (I’ve read all three of the above in studies, but I don’t feel qualified to judge the accuracy of the specific studies).

    Once we’ve analyzed areas where a certain group might excel, we can then ask the questions and analyze why we think this is the case. I’m sure some of the differences are due to what specific skills your region of birth selected for in the past, and the fact that only one human sex can conceive children, etc. Obviously a huge number of differences are instead mostly due to social circumstance. If we are willing to admit differences between people, we then have the ability to analyze the reasons for those differences and then help people improve themselves in whatever way they choose to (at least for the skills that are not largely genetic, though even that hurdle may start to disappear someday). If we must be politically correct and say everyone is equal in every trait/skill potential, we subjugate the limits of scientific research to things that won’t anger people if it ends up that there are real differences in some areas between people. My suggestion is that as science finds those differences, please don’t take them so personally. Do argue against the research if you feel it is not scientifically valid, but don’t argue against it because your ethical intuitions lead make you hope it isn’t true. Let the science inform your ethical judgments, but your morality of equal treatment shouldn’t depend only on the slowly shifting sands of scientific knowledge and your hope that, scientifically, every person has equivalent potential in basically every area. Even if the relative differences are small, they likely still exist. What is the point of pushing for sexual/cultural diversity if we must be so politically correct that we are not willing to admit that different people have different viewpoints, experiences, and abilities, at least to some extent, and these traits might more often/generally apply also to their group?

    Though outliers on the high end of an “intelligence scale” are by definition a relatively small number, it is often these outliers that make great breakthroughs we need to advance research and technology. To dismiss them as not being “the drivers of society” is discounting their importance. This is true no matter if those outliers in question are female or male, what race they are, etc.

    I’m sure I’ll be labeled as some kind of racist/sexist for posting this, but I’m going to click post anyway, because I strongly believe we need to be intellectually honest and not discourage real research into human evolution and capacity, but that we can do so in a way that does not force us into ethical dilemmas concerning the results of the research.

    #5 – I’m pretty sure he’s alluding to the fact that the Y chromosome is so much smaller than the X chromosome.

    If you’re female, you get an equal contribution from each parent.

    Mitochondria are really separate lifeforms. They’ve been able to shed a large number of genes due to their consistent and mostly safe environment (are there viruses that target mitochondria and chloroplasts?), but I don’t think we get to claim their DNA as our own.

  17. Ichthyic says

    ahh, EB, where were you when EO Wilson was getting death threats for publishing Sociobiology?

    *sigh*

    I do hope that your attitude will eventually become mainstream (even within the scientific community, let alone the public).

    I’d be happy to share any flak you receive for your post. Not only does the subject (sociobiology) generate much heated controversy, but the research involved relates directly to many subjects covered in this blog, from development, to psychology, to evolution.

    However, personally, I still would consider the more important issue for this thread to be the one of domestic violence, specifically.

    I do hope that sociobiology might be a topic where a new discussion thread might open some time, and it would be a point of focus.

    I have little hope, however, based on past experiences trying to blog the topic on a public forum, that it would get much beyond the meta-analysis stage.

  18. says

    Thanny @16,

    If you’re female, you get an equal contribution from each parent.

    Up to a point, Lord Copper. That might be true if we look only at nuclear DNA, since as you point out the X is bigger than the Y. Female or male, though, we all got our mtDNA from our mothers. You are (verging towards) correct, I suppose, insofar as inheritance of a paternal X (i.e., being female) offsets the “extra” maternal inheritance of mtDNA a bit more than does inheritance of the father’s Y, the latter chromosome being smaller.

    Mitochondria are really separate lifeforms… I don’t think we get to claim their DNA as our own

    Protoeukaryotic chauvinist! The “our” you speak of is a chimera. We (and virtually all our eukaryote cousins) are the result of the amalgamation of an early eukaryote with a prokaryote (two prokaryotes, in the case of our relatives the plants). The mtDNA is as much “ours” as the nuclear DNA. Anyway, a fair bit of our original mtDNA has, as I understand it, migrated to the nucleus. I’m not about to go in and shove it back out for being “foreign”.

    That ancient marriage, BTW, continues to have profound effects today (over and above being able to use oxygen, I mean). If you haven’t already, check out Mark Ridley’s Mendel’s Demon, which suggests among other things that endosymbiotic organelles explain why we have gender (not sex, which we’d have anyway, but the male/female distinction).

    “If we found out that Mediterranean people, for example, are much more likely to be resistant, would we dismiss this research as racist toward Hispanics?”

    If we did find such a difference, what makes you so sure that it would be due to a genetic factor and not due to a difference in lifestyle? By assuming that ANY difference between two groups of people who happen to have genetic differences can be ascribed to those genetic differences, and not to any other differences between the groups, such as lifestyle or upbringing, it is YOU who are ‘dismissing’ potentially useful remedies.

    Some ‘races’ are apparently more succeptible to heart disease than others. Since lifestyle is known to be a factor in heart disease, should we not pursue the possibility that it may be the different lifestyles of those ‘races’ that are responsible? An avenue far more useful than the genetic one, since it offers the possibility of transferring the benefits of that lifestyle to other ‘races’, in a way that we cannot transfer genetic advantages.

    Basically, the assumption that advantages must always be genetic, and the refusal to consider any other possibility, is extremely popular with people who have no desire to remove those advantages, and are looking for an excuse to do nothing about them.

  21. Ruth says

    “What is the point of pushing for sexual/cultural diversity if we must be so politically correct that we are not willing to admit that different people have different viewpoints, experiences, and abilities, at least to some extent, and these traits might more often/generally apply also to their group?”

    You are conflating individual differences with differences between groups. The two are actually to a certain extent contradictory. By saying ‘group A have trait X and group B have trait Y’, you are actually DENYING the possibility of diversity within those groups, and treating all members of a particular group as if they were more alike than they in fact are.

    Gender and racial stereotyping do not celebrate diversity, they reject it. They may offer a variety of acknowledged traits, but they do not give choice, since each individual is only offered one option, the one corresponding to their gender or race. Anyone who displays traits which are ‘unexpected’ for their gender has a much harder time getting those traits acknowleged than someone of the gender for which those traits are ‘expected’. In short, many maths teachers are slower to recognise mathematical ability in girls than in boys. We see what we expect to see.

    Diversity requires that since small statistical differences between groups cannot tell us anything useful about an individual member of one of those groups, we relegate such differences to the realm of ‘interesting, but useless’ information, i.e. trivia.

    36 years sounds like an urban legend to me. And why would this be a federal rather than a state offense? Can anyone confirm the truth of the “36 years in a federal pen”?

    I’m not sure there’s a way to get the children to understand this on a visceral, as opposed to academic, level. True and very sad story:

    I worked at a shelter for domestic violence victims. One day my co-workers and I brought stuffed animals for the children. An angelic-looking little girl, probably 3 or 4 years old, immediately picked out a plush green frog and began to hug it. Within half a minute or so, a fierce expression came over her face as she put her thumbs at the frog’s throat and began to repeatedly beat its head against the floor.

  23. Azkyroth says

    It’s certainly possible that there may be biological differences in abilities between males and females, but I’d find the claims that such differences have been found a lot more credible if their proponents demonstrated that they had adequately controlled for various biases and environmental influences (the “Pygmalion effect“, Wikipedia cited for convenience, is the first one that comes to mind, but not the only one). Many, especially those reporting research secondhand or trying to draw large-scale conclusions from various studies, don’t even seem to have heard of or considered such influences, instead naively attributing any relatively consistent differences, in test results or behavioral inclinations, between groups to genetic influences or, in terms of gender differences, to the direct effects of hormones on the brain (what I pejoratively call the “Two Humors” model). I’d also be more favorably inclined if the attempts to communicate those results to the public made clearer that 1) the differences measured are almost invariably of a few percentage points, not the radical gap the popular Mars/Venus model (or the “women are simply inferior” hypothesis about the pay gap) would suggest, and reflect averages, not absolutes (my daughter, for instance, impresses pretty much everyone who observes her with her apparent spatial abilities, despite the general perception of boys and men as “better” at spatial tasks).

    I’ve never felt it was right or defensible when I’ve lost my temper and become violent, and on the occasions where I’ve found myself grabbing my wife’s shoulders or pushing her, I’ve explained to her later, over her protests, that it was NOT her fault, that what I did was NOT ok or justified, and that it reflected a problem with ME, not her.

    First rather than perpetrating the myths of domestic violence in another thread on the Internet, in the commission of domestic violence women are not lesser than men as perpetrators, but somewhat higher. The basic (rough) population numbers I got from the CDC archives a decade ago are: Man-on-man (homosexual) 2% of all couples. Woman-on-woman (lesbian) 3% of all couples. Man-on-woman (heterosexual) 2+%. Woman-on-man (heterosexual) 3%.

    Women are also more likely to use deadly force or weapons when they attack their partner, regardless of gender.

    You can find out more about it if you wish because having been through the wringer with a violent, abusive ex-spouse and horrific divorce and three-year custody battle, I’m a little to scarred to go beyond pointing out that what you’ve likely been taught is political bullshit and not reality. It’ll take some work because it’s not easy to sift through the politisation in the initial stages of fighting domestic violence it was female-oriented organizations that made the claims and took all the space. But it’s not like it’s not known. It’s been known to psychological researchers since the late 1980’s that the NOW figures were bullshit and since the 1990’s what the actual basic rates domestic violence from a scientific (not a crime report) basis.

    Second, it’s not always mental. Some people have a hyper adrenal reaction to stress because (according to the theory) they have low seeratonin levels. The current treatment is Prozac or some other seratonin re-uptake inhibitor.

    Anyway, have to go.

    I had understood there was a -slight- statistically-significant higher IQ in men? Even so, just because the average is a point or two higher doesn’t mean that every man is smarter than every woman.

    Hell, if it’s true that men have more variance, wouldn’t that mean that a bunch of women, clustered around the mean, would be smarter than a significant portion of the men?

  26. Brandon P. says

    “I have to laugh when I hear conservatives blame the system because boys are underperforming”

    Especially when you remember that when certain ethnic groups are more likely to have problems in school, they refuse to blame any problems in the system and instead blame either inferior genes or culture. Hypocrites.

  27. Azkyroth says

    Hell, if it’s true that men have more variance, wouldn’t that mean that a bunch of women, clustered around the mean, would be smarter than a significant portion of the men?

    It’s also worth considering the effects of practice and expectancy on measured abilities, and the fact that historicially IQ tests have, as I understand it, been mainly developed by men (this becomes significant in the case that men and women are about equal in terms of their overall ability to perform a given task but tend to approach it in different ways). It’s also worth noting that women especially are encouraged, sometimes explicitly, to “play dumb” in order to be more appealing to men who “don’t like girls who read big books”; is it really safe to assume that this habit will magically disappear, for each and every woman who has adopted it, when a Scantron is shoved under her nose?

    There are so many confounding factors that, to my knowledge, no ethical human experiment has been developed to control for, that the blithe assumption that consistent measured differences, especially those that correlate with cultural prejudices, are purely biological seems more like wishful thinking than sound science.

    That said, I’ll admit that there are some traditionally male roles in which women will definitely never be equal to men and which women should not attempt to play: “sperm donor” comes to mind. ;/

    Incidentally, good point, because I’ve met entirely too many people who are quite willing to believe that the fact that men tend to score a little higher than women, on average, on certain tasks most definitely does mean that every man is smarter than every woman, at least as concerns those tasks.

  28. EB says

    Ruth, I believe I stated that I actually agree with your first point in the same paragraph you quote from my post:

    “It wouldn’t mean the difference is essential/genetic”

    Whether or not any differences between groups are genetic or social, we just shouldn’t deny them. We should do what we can to learn about them and their causes to give everyone the information necessary to excel and enjoy life. I have no interest in making excuses to do nothing concerning the condition of my fellow humans – much the opposite, in fact. I’m encouraging research into these differences to help improve life for everyone. I’m just worried that examining differences will encourage some misguided people to be less tolerant, instead of becoming more tolerant. I’m concerned I will not live to see the day where tolerance is expected, not the exception.

    You say that genetic differences can’t be transfered to other groups, but that may be a temporary technological limitation, depending on future medical/biological research and decisions about any ethical issues involved in each case.

    I also agree that the differences between racial/sex groups are likely very small in most cases and it is problematic to specialize from a group to an individual. But imagine we found, for example, that the average Germanic tribe descendant, due to slight inherited differences in ATP, had slightly more efficient muscle contractions. It might be a tiny difference, but one with a significant effect on the result of a marathon. To use a real-life example, Europeans have higher rates of cystic fibrosis (a genetic disease). After taking this into account, a doctor may be able to adjust her probabilities when quickly diagnosing a patient with cystic fibrosis-like symptoms. The trend of science thus far is that more and more traits seem to have at least some genetic influence – certainly not everything, but likely more than we know about now. It may be scary to think that too many of our traits might be even partially genetic, but our hope that those numbers are small shouldn’t slow our scientific investigation into this area.

    Most diversity plans define diversity by sex or race. If one doesn’t believe that sex/race are good ways to increase “true diversity”, because the differences between sex/race groups are too small, on average, then we need an alternate definition of diversity. For example a college might consider instead (or in addition) diversifying using some non-sex/race traits such as ensuring that they have a reasonable selection of low, middle, and high income students and students that come from single parent, gay/lesbian parents, and traditional families, etc. Such a plan might cool off some of the current heat over affirmative action but still provide significant advantages to the poor or single parent families or all races.

  29. Broken Spirit says

    When I was six I collapsed in front of a crossing guard who then called an ambulance. The hospital found a blood clot in my brain and the x-rays revealed a history of skull fractures. They called the cops, who had a long talk with my parents. Thanks to that talk, the bone breaking ended: no more getting crowned with frying pans and rolling pins. Also, the ear boxing stopped, but that may have been an oversight. (My eardrums healed, thanks for asking.)

    The battering did not end. My mom had learned as a kid how to fight with her fists, and she had a overhand right that was often good for a knockout, but sometimes I’d get only the blue flashes and stay conscious. All my eyeglasses got broken by her while they were on my face.

    Where was my dad? Standing guard, keeping the neighbors from interfering.

    Why did I get singled out for the violence? I think it was because I was the well-behaved one. My brother and sister were rebellious and would not obey. I would. I tried to obey better, trying to improve myself, but all my efforts came to nothing.

    When I turned 21 I was legally allowed to leave, but not a day before.

    I can feel sorry for the woman in the video, but I feel a lot sorrier for battered children. The law works against them all the way down the line. The police will intervene only when the violence gets forced in their faces, and then all they will do is whatever it takes to make their job easier. Cops don’t fix things: their answer to everything is more violence.

  30. sailor says

    I notice that video cameras seem to be playing an increasing role in bringing things in into the open. I have seen recent videos of a protestor having his leg broken and one of a man at a Kerry meeting being tasered. In neither case did the violence seem justified.
    However this case – a man videotaping himself committing two crimes at once; spouse abuse and child abuse, is maybe worth a Darwin award.

  31. Caledonian says

    * Because it’s obvious that in category Y, which includes child-bearing and breast-feeding, men can do fuck all.

    Men can breast-feed. It takes surprisingly little to get men to lactate – they’re provided with almost-fully-functional mammary glands, after all, and some minor hormone treatments are all that’s needed to get the milk flowing.

    As for why IQ couldn’t be part of a sexual dimorphism – well, it’s because women have been discriminated against, both historically and recently. People who have been the victims of discrimination obviously cannot possess any of the negative traits allotted to them by the discrimination, and are probably superior to the discriminators in that way. That’s what being a victim is all about!

  32. says

    Disappointing, PZ.

    How is putting a wife beater and “Larry Summers” type arguments in the same post any different from shouting “Stalin was an atheist, so there”!?

    And how are the hysterical reactions to Summers’ speech any different from the creationists’ misrepresentations of scientific statements as they try to “refute” evolution? How are they different from the Christian Right’s babbling about their rights being violated whenever they aren’t able to force their views on everybody else?

    Just last week, a group of female faculty at UC-Davis successfully pressured the university to rescind its invitation to Summers to speak at the board dinner. This was happening about the same time as another UC school hired and – under right-wing pressure – immediately fired Erwin Chemerinsky as Law School Dean.

    Dogmatism and censorship stink no matter what ideological label their proponents prefer to wear.

    Katie: (#25) – Yes. If the variances are differ but the means are the same, there are going to be lots of less intelligent men out there.

    #21:

    Diversity requires that since small statistical differences between groups cannot tell us anything useful about an individual member of one of those groups, we relegate such differences to the realm of ‘interesting, but useless’ information, i.e. trivia.

    Let me be the first to say: “Lewontin’s fallacy”, with a touch of Lysenkoism.

    It seems that you are saying “diversity requires that there be no diversity”. Or perhaps there is micro-diversity and macro-diversity?

    Blake Stacey:

    The link you provided attacks a straw man and doesn’t address Summers’ hypothesis at all. This study is about earning PhD’s, while Summers was talking about getting tenure at Harvard. There is a world of difference between the two. I’ve done the former (damn, came close to doing it twice), but my mere presence here, in a comment thread of a blog, proves that I am too much of a lazy bum to ever dream of the latter.

    It is bullshit to try to falsify Summers’ hypothesis by looking at the 95th percentiles of distributions, or even at 99th percentile, when he was talking about roughly the top 0.01%. It is also bullshit to reduce the relevant ability to IQ when it is well-known that success in a research career depends on a set of factors of which IQ is but one (and possibly not even relevant beyond the 99th percentile level).

    So is Summers’ hypothesis true? Nobody knows; that’s the point. Summers said we needed more research into the issue. The widespread reaction was (and still is, see my comment above) that no, we don’t need no stinkin’ research, all we need is the Revealed Truth.

  35. Bunjo says

    Well done EB for trying to inject reason into the debate. There seems nothing more sensible than saying “if there is a reason why this group of people do not appear to benefit so much, what is that reason and what should we do about it?”

    Unfortunately as many people have found out this sort of scientific question runs counter to the received wisdom (that everyone is equally proficient at everything) and is shouted down.

    We can all provide anecdotes that polish our individual view of the world and its inequalities – but we need to know the truth before we can decide what we should do about it.

    Be careful, its a jungle out there.

  36. says

    Word. We’re not born with equal opportunities in life; it’s the duty of a liberal democratic state to confer them. If biological evidence shows boys are slower learners than girls, we should spend that much more time and money educating boys to bring them up to the same level. Or vice versa. An equal application of the state’s powers will just magnify biological inequity, which is no better than social inequity.

    So we don’t even need to know the answer here. If girls are outperforming boys in school, we should devote more resources to boys than we are, regardless of the reason for the gap. It doesn’t matter if that means boys are getting more than a “fair share;” “fair” is whatever it takes to level the playing field, which may not be level to begin with. We should create equality, not assume it.

  37. Rick says

    “. . . as if men and women are separately evolving species.”

    The genders can evolve differently as evidenced by the very fact that different sexes even exist. Why should physical differences among the sexes not also extend to the functioning of the material brain/evolutionary psychology?

    PZ, you kind of opened up the flood gates on this one. I’m just waiting to see how long it takes before the word, “strident” is bandied about. I see “hysterical” has already been used.

    That (indiscriminate levelling of the field) is a repressive and counter-productive idea – though you may not be smart enough to realise it for yourself. It’s effectively what the UK government has already been doing, by lowering standards of education and examinations such that the most intelligent individuals are unable to shine much above the retarded ones – and universities and employers then get stuck with having to provide remedial training, even if they successfully apply their own tests to sort out the good from the bad.

    People are not born equal and sometimes those inequalities are necessary for the furtherment of society as a whole, eg the high IQ individuals are needed for doing the things which only high IQ people can do – including first being permitted to acquire the superior levels of education which only they can genuinely do even if the government gives out free passes like candy to all the failures in order to obscure the differences.

    It’s vitally important to discriminate – but on the basis of real things, such as IQ and competence and honesty etc, rather than on fake prejudiced things, such as gender or colour, as tends to happen at present.

    Azkyroth:

    I’ve some experience with anger control issues myself, and I have a few observations/suggestions that have helped me.

    1) I’ve intentionally, over long practice, developed the instinct to avoid touching anyone when I’m angry. No contact means it’s a good deal easier to avoid hurting them.

    2) My parent’s always emphasized hitting a pillow or some clay or something if you’re mad. This doesn’t work for me precisely because you can’t really hurt either of those objects and that just makes it more frustrating. I make a point of having something around the house that it’s OK and safe for me to break. That way, if I need to I can leave the area and go smash something until I’ve blown off some steam. Maybe some cheap shelves in the garage or something? (I’ve got an old water heater that I just pound dents into)

    Not sure if either observation will help you, but I thought I’d offer the advice at least. My issues started at a young enough age and I started working on them early enough that it’s largly in hand now, and I hope one day you’ll be able to say the same. The important thing to my mind is that you know you have a problem and are working to fix it, that alone is admirable.

  44. says

    Now where did I read this…

    It is an article of passionate faith among “politically correct” biologists and anthropologists that brain size has no connection with intelligence; that intelligence has nothing to do with genes; and that genes are probably nasty fascist things anyway.

    Just sayin’.

    Every discussion on sociobiology or evo-psych seems to devolve rapidly into a shouting match and a flurry of cites and studies which the other side always insists are meaningless… I’m firmly on the genes-are-important/gender-is-not-a-fiction side, but I’m routinely embarrassed by some of the people trying to argue the case; a lot of the proponents of the evo-psych view, especially in the popular press, seem to do little more than revel in the political incorrectness of it all. I remember an article in the Times or Guardian or somewhere whose headline was “Sorry women, you need men after all” and whose tone went rapidly downhill from there. I would have liked to see a response by a female physician – “Sorry men, you’re going to die younger.”

  48. Ichthyic says


    If we did find such a difference, what makes you so sure that it would be due to a genetic factor and not due to a difference in lifestyle?

    because it really isn’t that hard to control for general factors like that, provided you get a large enough sample size.

    besides, while you START with a correlation, you certainly don’t stop there.

    the next set of studies would of course be specifically looking at the causative factors behind the correlation.

    that’s science, at least, that’s how it’s supposed to work, anyway.

  49. Ichthyic says

    Many, especially those reporting research secondhand or trying to draw large-scale conclusions from various studies, don’t even seem to have heard of or considered such influences,

    as expected, this debate will endlessly degrade into a discussion of meta-analysis, without even bothering to examine the actual studies that spawn the meta-analysis to begin with.

    can’t you see what a waste of time that is, if you really want to get at the guts of the science underlying the “secondhand” analysis?

    not like this isn’t the direction EVERY public discussion of the larger issue of sociobiology ends up taking, but I thought, just this once, it might be avoided.

    *sigh*

    seriously, and my last comment before this degrades into a silly debate of how “Rush Limbaugh” types misuse the results of studies that would be considered to fall under the purview of sociobiology:

    if you want to debate the merits of studies elucidating the genetics of behavior, or of any trait for that matter…

    LOOK AT THE PRIMARY LITERATURE

    ignore the damn media meta-analysis.

    If, OTOH, you actually want to discuss how the media and armchair analysts misuse behavioral data, feel free to continue in the same vein. Hell, that debate has been raging for ages, long before Wilson released Sociobiology.

    There’s a reason that Trivers is considered to be one of the largest contributors to modern evolutionary theory of the last century, and it’s not because of his politics.

    His hypotheses have been extensively tested, and found to be sound.

    now all you have to do is disconnect these two entirely different things.

    sure, there are debates within the scientific community, but they are hardly going to be resolved by the results of popularity contests within the media.

    those decrying the value of evolution in explaining human behavior have to be very careful to explain what exempts any specific trait under study in humans, before discounting evolutionary hypotheses.

    saying there is no control for environmental effects is insufficient without actually analyzing a specific study to see whether controls were in place to begin with. You can’t just postulate any specific study ignored environmental effects without actually looking at the study in question.

    Moreover, many secondhand reports of “controversial” studies are looking at studies that are indeed only correlative in nature. The scientists doing these studies are only looking for suggestions for further research, based on the results of the correlation, conclusions are tentative at best at this stage, without further studies attempting to look at the potential causative factors involved. However, we often wouldn’t even have a clue as to what the causative factors might be without the correlative studies to begin with.

    On top of that, as you all should know by now, teasing out just how much influence genetics has on a specific trait is often quite difficult; most traits are in fact, quite variable. that’s not saying there is no genetic influence, it’s saying that it’s not completely controlled by genetics.

    think about all of that before making sweeping proclamations about the value of evolution in studying human behavior.

    The danger is, in letting the results of secondhand analysis dictate you opinion on the science, you essentially reject the idea that evolutionary theory can explain human behavior.

    be sure that’s what you want to do before you do it.

    IQ may be sexually dimorphic. But you have to take the evidence with a grain of salt. It’s highly possible that the studies that conclude “wimminz are genetically chained to the kitchen” are just a sexist variation on the “black people are naturally lazy” post hoc racist bullshit.

    And because of the complete dominance of the white patriarchy for thousands of years, we should take an extra-critical view of evidence that merely reinforces existing prejudices.

    Concerning the actual topic, it may well be that there is a biological difference. It may well be that the male:female ratio among full professors, if left to biology alone, would be 60:40 or even 70:30 as opposed to 50:50. Hey, perhaps 80:20, who knows. But in Austria it was 93:7 last time I checked (tendency shrinking), and that even though the ratio among first-semester students is 42:58 (with a nice gradual change the closer you get to the full professors).

    I don’t know how your last sentence connects with the rest.

    In my post, I was pointing out the naive stupidity of the preceding suggestion because of the fact that people absolutely cannot ever be raised to the same standard of ability (although they could temporarily be given something external such as the same money – only to have some rapidly waste it, of course). People are not and never will be equal (natural variation within the species and all that). The only thing which can ever be done in terms of abilities is to suppress them to the same level (or somewhere near it) – and that’s a bad thing for everyone.

    ow is putting a wife beater and “Larry Summers” type arguments in the same post any different from shouting “Stalin was an atheist, so there”!?

    The belief that women are inferior to men and better equipped for a life of servitude to men than a life lived freely and independently is the direct cause of wife-beating. Men who beat their wives feel women are inferior to them, owe them service as their role in life, and that men should be in charge because they’re smarter and generally superior in most ways.

    Summers was feeding the belief that women are not fit for male roles, which of course feeds the flip side that women’s “role” is service to our male superiors. You start with the idea that women shouldn’t compete with men in academia, then argue that women shouldn’t compete with men at all and should stay in the kitchen and you establish the philosophical groundwork for a man to berate his wife as if she were an appliance with certain duties (including mind-reading, as well as cooking, sex, and cleaning) that wasn’t functioning properly and is appropriate to be kicked around like it’s some piece of trash.

  62. Azkyroth says

    Caledonian and others:

    I think what you’re failing to grasp is that the resistance many people display towards announcements that certain groups are different from others in terms of their inherent abilities stems mainly from two sources, and neither of them is an objection in principle to the idea of inherent differences. First, there is a very well documented history of such findings being fabricated, in whole or in part, to retroactively justify covert and sometimes overt race, class, or sex discrimination, and given that historical record, skepticism that THIS time, despite so many often laughable earlier failures, we’ve managed to eliminate the biases, methodological flaws, “everyone knows”es, and wishful thinking from the research and really Get It Right is perfectly appropriate. This is all the more true given the enormous range of possible confounding factors that, to my knowledge, no ethical experiment on humans has managed to (or, arguably, can even in principle) eliminate, and the fact that in spite of these factors many people blithely attribute whatever differences they observe to genetics or hormones–until those environmental influences are addressed, how can one possibly declare with confidence that a certain observed difference is innate? Prematurely jumping to conclusions that just happen to line up with prevailing cultural biases undermines one’s credibility among those who consider small-t truth to be valuable, and this is entirely appropriate.

    Second, I think, is the fallacious conflation by people on both sides of the argument of two distinct propositions. The first, in summary, contains four subcomponents as follows:
    A. There may be patterns of inheritance such that genes which are associated with certain cognitive or physical abilities are slightly different, on average, between human lineages, with the result that people from certain hereditary backgrounds may be more likely to have inherited genes that confer an advantage in the ability to understand and perform certain cognitive tasks, compared to others with a comparable background, environment, and level of education.
    B. Similarly, the effects of the genetic differences between humans with two X chromosomes and humans with one X and one Y chromosome, and the effects of differing levels of hormones, on the development and operation of the brain may tend to result in differences in the brains of men and women that may tend to result in slightly better performance on certain cognitive tasks for members of one sex than members of the other sex with a comparable background, environment, and education (the existence of differences in physical capabilities between men and women is relatively uncontroversial).
    C. Our present understanding suggests that these innate differences between the average abilities of populations, if they exist, are relatively small, and should not be construed as implying a necessary and absolute difference between any given member of one population and any given member of another population.
    D. Nevertheless, differences in average “end result” abilities that are traceable entirely or primarily to biological differences between groups may exist, and are worth investigating.

    This is a reasonable position, one that is receiving some support from the available research, and one that should not be controversial when the claims made in line with it can be supported by adequate evidence and the potentially enormous issues of bias in designing experiments and evaluating results, and the issue of controlling for the confounding factors of non-biological influences on the development of human abilities, can be resolved.

    However, those who advocate the idea that of “inherent biological differences in abilities between groups”, and the people who seem to be resistant to or offended by this suggestion, habitually conflate the above with the following proposition (really a mess of shallow intellectual and political conceits upon which an unwarranted coherence has been imposed here): “There are most definitely inherent biological differences between racial groups, in terms of physical and cognitive abilities, and between biological sexes in terms of cognitive as well as physical abilities, which are approximately in line with popular perceptions about the relatively abilities and merits of these groups, and these differences explain the present social inequality and perceived differences of ability between these groups. These biological differences may or may not be completely insurmountable, but either way, the effects of environment and social influence on the development and performance of physical and cognitive skills can, except in the most atypically blatant of cases, be safely ignored, and both the differences and the existing inequalities should be accepted, or even codified.” Proponents of this view tend to ignore various social and environmental influences on the development of human skills, the documented plasticity of the human brain and cognitive function, the difference between “average” and “absolute”, the fact that so far, research suggests that what differences exist are small, and the possibility that those small inherent differences may be overcome through additional effort in learning and practicing cognitive and/or physical skills, and also have been known to make odious suggestions to the effect that only those who are above a certain threshold in terms of expected or tested capacity for development of certain skills should be actively taught, or even permitted to learn, those skills.

    Obviously, rejecting the idea of “biological differences” on the basis of a rational resistance to the proposition above is unscientific and fallacious, and it would nice to see people on both sides of the argument accurately distinguishing between the two. Nevertheless, I hope you can see why, in light of the above, claims of “inherent differences in ability”, even when they do not explicitly reference the supposed “natural superiority” of certain groups, tend to make people uneasy. :/

Similar attitudes, one of which is expressed violently and one of which is expressed in a nonviolent and socially accepted manner. Does this make more sense?

    Incidentally, what the hell just happened and why was there no warning? (Or did I miss it?)

    bullfighter, I don’t follow. Did you read the whole article? Do you really think Summers had a study like this in mind?

    You also say, I’d blindly guess that women got tenure under Summers at a higher rate than under his predecessors,

    Found while trying to figure out what you meant with the first bit: “The percentage of tenured job offers made to women by the university’s Faculty of Arts and Sciences has dropped dramatically since Summers took office”.

  65. says

    To put it another way: Larry Summers showed no sign of wanting to study the university’s end or (in the linked article) the interviewer’s end of the phenomenon. It seemed to me like he wanted to direct our attention away from the behavior of the authorities, towards alleged problems with the applicant.

    “But imagine we found, for example, that the average Germanic tribe descendant, due to slight inherited differences in ATP, had slightly more efficient muscle contractions. It might be a tiny difference, but one with a significant effect on the result of a marathon. ”

    Does this mean that you would take race into account in selecting someone to represent your country/town/college in a marathon? Or would you base your decision entirely on the actual comparative performance of the potential contestants?

    In other words, even in the context of marathon running, any minor differences in the AVERAGE perfomance of members of different races are of no use whatsoever in making decisions about INDIVIDUAL MEMBERS of those races.

    The problem comes when people treat such information as if it WERE useful, and privilige a poorer performing member of the better performing race/gender over a better performing member of the poorer performing race/gender.

    Ask any woman/black who’s ever lost out a job opportunity to someone with inferior abilities and experience, but the ‘right’ gender or colour (or even the ‘right’ accent or old-school tie!).

  67. Roel says

    I’ve always been told that the Y chromosome hardly contains any genes. However, if the sexists are right, some genes these must be!!!

  68. Ruth says

    “If we did find such a difference, what makes you so sure that it would be due to a genetic factor and not due to a difference in lifestyle?”

    “because it really isn’t that hard to control for general factors like that, provided you get a large enough sample size.”

    How do you ‘control’ for things when you don’t even know what they are?

    If two groups have BOTH a different genetic make-up AND a different diet, how on earth are you going to separate out the two? I suggest you google ‘confounding variables’.

  69. Ruth says

    “saying there is no control for environmental effects is insufficient without actually analyzing a specific study to see whether controls were in place to begin with.”

    I don’t need to look at a study to find out whether it controlled for the effects of being treated by society as ‘male or ‘female’, since I know that it is impossible to control for such factors. Do you really expect to find that the scientist in question has managed to find a sufficiently large sample of individuals who have NOT been treated by society in line with their biological sex?

    True, but if there ARE such average differences, then disproportionate outcomes can no longer be used as proof that such discrimination is occurring. To continue the example of Germans being naturally better at distance running, if there are 7 Germans on an Olympic team of 10 people and the population is only 40% German, that doesn’t prove discrimination – the group with a higher average is *likely* to have a higher proportion of the exceptional performers.

    If you come at the problem from the other end – not knowing which subgroups might be statistically better performers – then *no* statistical anomaly in the results can be used to prove discrimination, because you don’t know that it doesn’t reflect a statistical difference in the source population.

    To take a much less hypothetical example, there are certain hypercompetitive jobs where it’s necessary to be obsessed with the job to the detriment of all other aspects of your life in order to reach the highest levels of success. If men are more likely than women to have this pathological (IMO) degree of obsession with success in one specific area, *even without any difference in actual capability*, more of the people who reach the highest competitive levels will be men, whether discrimination is occurring or not (and this phenomenon will occur across a range of different competitive arenas, provided that they all share the property that you need ability *and* obsession to reach the highest levels).

    This, of course, doesn’t prove that discrimination isn’t occurring as well. But it does demonstrate that discrimination is not the only possible source of unequal outcomes.

    Amanda:

    You are completely misrepresenting Summers. Connecting anything he said with “the idea that women shouldn’t compete with men in academia” would be utterly ridiculous if there weren’t so many people who actually bought that as truth; that fact changes ridiculous to dangerous. (Incidentally, this is a blog famous for discussions of things that would be ridiculous if legions of people didn’t actually believe in them. It usually comes out against them, however.) Saying that “Summers was feeding the belief that women are not fit for male roles” is equally wrong, unless you think it is OK to blame him for those who misinterpret his statements the same way as you do, but whose personal agendas are opposite of yours. But in that case, you also must blame Darwin for sweatshops and ghettos; social Darwinism is no farther from the theory of evolution that misogyny is from the ideas expressed in Summers’ maligned speech.

    But that’s not all. It really should be obvious to everyone here (and certainly to PZ) that, even if somehow I was completely wrong in understanding what Summers said, and you were completely right, it would still be terribly wrong – both intellectually and morally – to assert a causal connection between ideas like Summers’ and pathologically disgusting crimes like the one in the video (which I will not watch, but PZ’s description was enough to form a very strong opinion about it). Chilling speech by appealing to nebulous slippery-slope arguments has always been a favorite tactic of authoritarians, religious and secular, and it is a trivial exercise in logical consistency to turn its own argument against it. But I’ll stop here and leave that exercise to the reader.

    hf:

    So my blind guess was wrong. Big deal. As I wouldn’t have attributed an increase to Summers, obviously I am disinclined to attribute a decrease to him, either.

    But I have a question for you: is the decrease in aggregate only, or does it persist if tenure decisions are examined department by department? Summers did favor funding of natural sciences and more empirical social sciences (i.e., economics) more than humanities and “soft” social sciences, and the latter have a higher percentage of women on faculty. Such funding decisions would then tend to result in fewer women to get tenure university-wide, but they would not by themselves reduce a woman’s tenure prospects any more than those of a man in the same field. Thus, meaningful measurement of trends must be made department-by-department, not in the aggregate.

  73. says

    hf: I forgot to respond to the first part. Yes, I read the whole article, and yes, I think a study like this would fit in the broad research agenda that Summers had in mind. BTW, did you ever read Summers’ speech?

  74. Bunjo says

    Just in case anyone is interested here is the Larry Summers Transcript

    It always seemed to me that what he said was unreasonably exploited by those people who had other axes to grind. However, just like sports team managers, once the ‘team spirit’ has been broken (even by some mean spirited clique) the ‘leader’ has to go.

    I do worry that feminists (particularly academic ones) can be seen to over-react (Duke Lacrosse ‘rape’ allegations, another example). This damages the very reasonable aim of achieving equality for women. Personally I would like to see equality for men too, but that is another argument…

  75. Ichthyic says

    Do you really expect to find that the scientist in question has managed to find a sufficiently large sample of individuals who have NOT been treated by society in line with their biological sex?

    you actually haven’t read many (any) related studies of this type, have you?

    you don’t control for factors like that in the way you are thinking; you control by correlating across entirely different social structures to begin with.

    different societies (even different groups/classes withing the same societies) treat different gender related issues quite differently, and if you disagree with that, not only do you need to actually spend some time actually reading some of these studies, you need to spend more time travelling outside of your hometown.

    so yes, it’s really not that hard to control for, given the limitation (acceptable) that you actually can’t produce the kind of controls you would in an animal study, say, where you can physically manipulate the situation.

    to think you can handwaive it all away by saying “control is impossible” is merely the barest of hyperbole.
    It rather implies you think that studying human behavior is impossible.

    that’s a tall order to prove.

  76. says

    Indeed I have, though I saw it a while ago. Look, we have Chris here saying that a difference in attitude for men and women can explain inequality “whether discrimination is occurring or not”. Well, we’ve already shown the existence of unconscious discrimination that could not only explain inequality directly, but also seems to create a difference in attitudes in the study I mentioned. See here for another known factor that seems relevant.* Chris et al, if you want us to look for unproven causes, I suggest you give us some reason to think that the ones we know about can’t explain the phenomena.

    *And an answer to likely criticism, from a Pandagon post that Google doesn’t like for some reason:

    The most obvious men who live permanently without women are gay men, and the stereotype of the permanent bachelor is about as different as you can get from the stereotype of the temporary bachelor. Gay men are stereotyped as neat and fussy, which is a stereotype of femininity on a certain level but also speaks volumes about what we think men do want long-term-they want cleanliness, and if they aren’t going to have a woman to do it for them, they will bite the bullet and do it themselves. The neatness stereotype is also applied to straight men who live alone for a long time. Witness Jerry Seinfeld. Or your stereotypical priest, for that matter.

  77. Ichthyic says

    How do you ‘control’ for things when you don’t even know what they are?
    If two groups have BOTH a different genetic make-up AND a different diet, how on earth are you going to separate out the two? I suggest you google ‘confounding variables’.

    you are way off in hypothetical land. sure, you can have multiple variables affecting a correlation analysis. that’s why we never say that correlation=causation. It’s also why we have different statistical regression models to handle multiple variables in a particular correlative analysis.

    simply stated, correlations imply things that are then tested for causation, and we don’t need to necessarily tease apart potentially competing variables to show a correlation between a measured value.

    IOW, if potentially confounding variables appear in a correlation analysis, we simply account for them within the regression model used, and afterwards, we work to eliminate those individually by testing each one for causation (in completely different studies).

    hope that makes sense, without actually looking at some case examples to show you what I mean.

    It would be difficult to do in this format, but would you prefer that?

    would you prefer to examine a typical correlative analysis to see how it works, how the regressions are done and why, and how the conclusions typically suggest further work on the potential causative factors suggested by the correlation?

    while it would take too much time for me to reconstruct an a typical regression analysis here, I’m sure a search on google would pull up someone who already has done it.

    would that help?

  78. Ichthyic says

    azky, re: #63

    sure, what people do with the supposed implications of any given study can obviously be just as important as the actual results of a particular study itself.

    it’s just that I so commonly see people, even scientists, who in every other area of scientific endeavor wouldn’t question the value of scientifically investigating something, who knee-jerk reject the idea of sociobiology simply because of the fear of what someone else might to with the implications of the research.

    this has been going on for ages, especially within the field of evolutionary biology.

    I completely agree with your overall statement, but want to stress that we can’t simply abandon science in any area because it makes certain people feel uncomfortable, or because others might run with whatever implications they project onto a set of data (even the scientists who collected the data, for that matter).

    Stem cell research in this country was not banned because the research was faulty.

  79. Azkyroth says

    I agree. However, there has been such an extensive history of such egregious, jaw-droppingly-obvious-in-retrospect problems with the research itself that skepticism is called for in evaluating the results of those who claim they’ve really got it right this time.

    Also, it’s true that gender models and roles differ somewhat from culture to culture, but I’ve yet to hear of a culture where the broad pattern of women being encouraged to stay home and care for children and depend on men for protection and support while the men are taught to be strong and do the bulk of providing doesn’t hold to some degree. Can you name one? The prevalence of this model as indicating a purely biological basis for this arrangement would be more credible if human societies developed in a vacuum, which, unless one subscribes to creationism, they generally haven’t.
