Even tiny brains are complicated

This is impressive: scientists have scanned and imaged every neuron and every connection in a fly brain

. The data has been made freely available, and you can download the whole dataset, if you have 12TB of storage available.

Human brains have about a million times more neurons than a fly brain, and note also that this is morphological, rather than biochemical data, which is going to be even more complex. Adjust your expectations for mind uploading accordingly.

Cats did not evolve 80 million years ago

I mined the rich vein of ignorance and inanity that is Harun Yahya’s Atlas of Creation, and only got as far as one page before I was stunned into silence. He made a claim about cat evolution that even my evil cat found repugnant.

You know the Felidae are a fairly recent clade, appearing in the late Miocene, right?

Something in our culture is creating a lot of naive biological determinists

Here we go again. The Guardian has a profile of a guy who claims to be able to tell your sexual orientation from a photograph. It’s all bullshit, reminiscent of that Faception nonsense.

But his audience would also have been intrigued by his work on the use of AI to detect psychological traits. Weeks after his trip to Moscow, Kosinski published a controversial paper in which he showed how face-analysing algorithms could distinguish between photographs of gay and straight people. As well as sexuality, he believes this technology could be used to detect emotions, IQ and even a predisposition to commit certain crimes. Kosinski has also used algorithms to distinguish between the faces of Republicans and Democrats, in an unpublished experiment he says was successful – although he admits the results can change “depending on whether I include beards or not”.

He’s a psychologist. Everyone who has taken a psychology course must have heard of Clever Hans, the counting horse. You would say a number to Clever Hans, and he would pound his hoof on the ground the right number of times. He must know how to count! But no, it turns out that Clever Hans just knew to watch his owner, who was the one who could count, and who would change his posture or signal his relief when the horse reached the desired number. The whole point of that story was a lesson in interpreting your observations: you may think the subject is doing one thing, but he or she is actually doing something entirely different.

For a wonderfully thorough take down of Kosinski, read this article which exposes the flaws in his work. Kosinski claims he’s detecting a biological difference, that physiognomy and genes are somehow connected to psychology and behavior, so you can scan one and get an accurate assessment of the other. But he’s really pulling a Clever Hans, making a faulty association between the variables he wants to link, and ignoring a host of other variables where the real connection is being made. And those other variables are all culture, not biology.

In summary, we have shown how the obvious differences between lesbian or gay and straight faces in selfies relate to grooming, presentation, and lifestyle — that is, differences in culture, not in facial structure. These differences include:

  • Makeup
  • Eyeshadow
  • Facial hair
  • Glasses
  • Selfie angle
  • Amount of sun exposure.

We’ve demonstrated that just a handful of yes/no questions about these variables can do nearly as good a job at guessing orientation as supposedly sophisticated facial recognition AI. Further, the current generation of facial recognition remains sensitive to head pose and facial expression. Therefore — at least at this point — it’s hard to credit the notion that this AI is in some way superhuman at “outing” us based on subtle but unalterable details of our facial structure.

The Guardian article also points out another weird bias in Kosinski’s work.

This is where Kosinski’s work strays into biological determinism. While he does not deny the influence of social and environmental factors on our personalities, he plays them down. At times, what he says seems eerily reminiscent of Lombroso, who was critical of the idea that criminals had “free will”: they should be pitied rather than punished, the Italian argued, because – like monkeys, cats and cuckoos – they were “programmed to do harm”.

“I don’t believe in guilt, because I don’t believe in free will,” Kosinski tells me, explaining that a person’s thoughts and behaviour “are fully biological, because they originate in the biological computer that you have in your head”. On another occasion he tells me, “If you basically accept that we’re just computers, then computers are not guilty of crime. Computers can malfunction. But then you shouldn’t blame them for it.” The professor adds: “Very much like: you don’t, generally, blame dogs for misbehaving.”

I don’t believe in free will either, but for completely different reasons: I see it as a malformed question built on a foundation of dualism, a delusion that “you” are something independent of the physical, biological “you”. But I don’t flop down into the lazy thinking of biological determinism; that “I” am a construct of a meat computer does not imply that I am robotically fixed and incapable of change and growth, or cannot make decisions based on rational forethought or emotional desire. The real “I” is the whole, inseparable from glands and experience and calculation.

Likewise, biological determinism is bunk. Who we are is not simply a product of built-in genetic factors — genes respond to environment. It’s all one inseparable gemisch, and anyone who tries to argue that genes drive behavior is a fool. It’s always genes entangled in history and environment.

It’s just like fishing for rocks

A meteor blew up in the atmosphere off the coast of Washington state back in March, and today the EV Nautilus is going to poke around, looking for meteorite fragments, and the search will be streamed live.

My brother lives just south of meteorite field. I should nag him to get off his lazy butt, get in his boat, and go dive for a few fragments for me. They don’t say how deep the Pacific is at the site, but I’m sure he can just rig up a magnet on a long stick and grab a few.

At least I’ll put up the video stream in the background this morning.

You think this is amusing?

Look at all these clips of frogs and toads eating fireflies, and afterwards flickering and glowing as the insects continue to strobe their tail-lights while inside their guts. Maybe it’s a little bit funny, but I’m wondering how it would affect predation on amphibians — after all, it’s night, and now the frog has switched on an internal light.

I’m also imagining the poor doomed bug shrieking, “Towards thee I roll, thou all-destroying but unconquering frog; to the last I grapple with thee; from hell’s heart I stab at thee; for hate’s sake I spit my last breath at thee.” They’re desperately signaling for anyone to come, calling down hell on their tormentor.

Hey! The Bell Museum is reopening in July!

I’ve been waiting for this: the brand new, shiny, grand Bell Museum is opening in St Paul in mid-July. Anyone else want to go? I’m all tied up the weekend of the opening, but some weekend in the last half of July I’ll definitely be making the trek and checking it out. I’ll announce a specific date in case anyone else wants to join me and get a selfie with the woolly mammoth.

Radiolab lets me down

I’m at the gym this morning, and I put on a podcast, as one does, and chose to start Radiolab’s series on reproduction and human development. Just my sort of thing, I thought.

And oh my god it is awful.

To personalize it and appeal to the masses, it resorts to rampant anthropomorphization and mischaracterization of the environment. Germ cells start out in the allantois, which is a “wasteland”. They migrate “pugnaciously” to the embryo proper, “looking for” the genital ridge, which is like a “cathedral” filled with somatic cells that are like “monks”, who then “care for” the germ line. They ask deep questions, like “does the cell know where it’s going?”, and no one says no, that’s a stupid question, it’s a single cell with no cognitive abilities at all. And it goes on and on.

I only listened to the end of that episode because I could not believe how much misinformation was being spread in order to make developmental biology ‘entertaining’. I’m not going to listen to the rest of the series, because I can’t afford to smash my phone.

If you must listen, there is a tiny bit of factual information in there, but it’s all been slathered in the goop of humanizing individual cells, and it is totally detestable in the way it tries to make happy cartoon people of developmental processes. Not recommended at all. Listen with extreme caution and skepticism.
