First world whines

One of the things that really annoys me is what I like to call ‘first world whines’. These are the complaints of people who live lives so pampered that the slightest inconvenience causes them to throw a tantrum.

Take for example, airline flight. This has become unpleasant for many reasons but the one thing that does not bother me is being asked to shut off personal electronic devices (PED) during the take off and landing stages. It seems like such a tiny price to pay in exchange for reducing the chances of the plane crashing. [Read more…]

The puzzle of rising IQ scores

Nearly three decades ago, work by James R. Flynn revealed that average IQ scores in developed countries were rising at a stunning pace, of the order of 0.3 points per year or more. Later work showed similar explosive gains in developing countries and that the rise (now dubbed ‘the Flynn effect’) is still continuing. How did he find this? Recall that although IQ tests themselves have changed over time, each revision requires the IQ scores to be normed to always have an average value of 100. So does someone who scores 100 today have the same IQ of someone who scored 100 say fifty years ago, since they took different tests? Flynn found that if you give people today old IQ tests, their scores rose steadily the older the tests, suggesting that IQ tests have got harder over time. (James R. Flynn, Are We Getting Smarter?, 2012) [Read more…]

Intergroup variations in IQ

The Jason Richwine dissertation, like its predecessor The Bell Curve in 1994, argued that IQ scores are a good proxy for intelligence, that intelligence has a substantial hereditary component and is thus largely immutable to change by external measures, and that high IQ levels are significant predictors of economic and social success in life while low levels predict a life of crime, unemployment, and general failure. According to Richwine, American Hispanics have average IQs around 89 (the overall average is fixed to be 100) and thus Hispanic immigrants will be a drain on society. (See here and here for earlier posts on this.) [Read more…]

The viruses hidden in our DNA

I have heard about retroviruses and that HIV belonged to that family but not being a biologist knew nothing more about what a retrovirus was and how it differed from any other virus. This article by Carl Zimmer explains what they are and in addition says that new research about them has revealed that we all have a lot of retroviruses that invaded our DNA a long time ago and that over time have mutated to become either inactive or dormant.

Internet addiction

Two years ago, I wrote about research that found that those people who tried to multitask (i.e., switch rapidly between different cognitive tasks) were highly inefficient in procession information when compared to those who did the same work sequentially. They suffered in all three major areas that would be necessary to multitask: the ability to filter (i.e., to detect irrelevancy so as to be able to quickly distinguish between those things that are important and those that are not), the rapidity with which they could switch from one task to the next, and the ability to sort and organize the information in the brain so as to keep track of the results of their different tasks.

Who invented the average value?

All measurements of a continuously varying quantity (length, weight, mass, etc.) have some level of uncertainty (more commonly referred to as the ‘error’) associated with them, due to the limits of the measuring instrument or limitations of the measurer. In order to mitigate the effects of this, nowadays we take many measurements and calculate the average value of the quantity. [Read more…]

Talk today on the Higgs particle

For those of you in the Cleveland area who are doing nothing important this evening, I will be giving a talk at 7:00 pm today May 8, 2013 to the Northeast Ohio Center for Inquiry on the topic The ‘God’ Particle:The reality behind the hype over the search for the Higgs boson.

It will be at the Mayfield Library, 500 S.O.M. Center Rd., Mayfield Village.
