Surely, all scientists will now finally agree that being right-wing is a form of extremely dangerous intellectual disability and that people who are leaning to the right need help and should not be laughed at.

This looks like a great read! Out of curiosity, which of the terms "cognitive system," "underwrites," "representation," and "conceptual" is the least ambiguous or vague in your opinion? :-)

Renewables overtake coal as world's biggest source of electricity

Developing countries lead the historic clean energy charge but the US and EU rely more on fossil fuels than before, a think tank study shows.

... C must consist of *environmental properties*; otherwise, there would be no background conditions and no causality, as G and E *exhaust* the possible causes of X.

Borysław Paulewicz @boryslaw.bsky.social · 8d

... It is important to remember that causal relations are *context dependent*, e.g., striking a match causes fire *in the presence of oxygen*. Back to G and E:
X is innate in the context C iff
p(X|do(G),C) = p(X|do(G),C,E).
Here is the subtle part: ...

Borysław Paulewicz @boryslaw.bsky.social · 8d

... an organism is literally the result of an interaction between G and E. Now does it make sense to ask if a property X is innate or not? If innate := caused by G, and acquired := caused by E, then yes, it makes perfect sense to ask that, with the following caveats: ...

An excellent example of enormous intellectual effort wasted only because people inconsistently use certain words. Here is a simple explanation:
We know that every trait of an organism is determined *jointly* by the genes (G) and the environment (E) bc ...

Gregory Kohn @kohngregory.bsky.social · 10d

This is an awe-inspiring and fascinating study that I thoroughly enjoyed reading. However, the overall framing in terms of "innate versus learned” is unnecessary. The innate versus acquired dichotomy is outdated and has been for a long time. www.nature.com/articles/s41...

Learned use of an innate sound-meaning association in birds - Nature Ecology & Evolution

Over 20 species of geographically and phylogenetically diverse bird species produce convergent whining vocalizations towards their respective brood parasites. Model presentation and playback experiments across multiple continents suggest that these learned calls provoke an innate response even among allopatric species.

This whole section really.

Finally: AI cannot do your job, but an AI salesman can 100% convince your boss to fire you and replace you with an AI that can't do your job, and when the bubble bursts, the money-hemorrhaging "foundation models" will be shut off and we'll lose the AI that can't do your job, and you will be long gone, retrained or retired or "discouraged" and out of the labor market, and no one will do your job.
AI is the asbestos we are shoveling into the walls of our society and our descendants will be digging it out for generations:

A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue.

The effect presumably comes from the absence of S-cones in the fovea.

Ted Chiang:
"The task that generative A.I. has been most successful at is lowering our expectations, both of the things we read and of ourselves when we write [...]. It is a fundamentally dehumanizing technology because it treats us as less than what we are: creators and apprehenders of meaning."

Shading body parts with a pencil, especially parts of the sex one is drawn to, is a time well spent. That is a common reason to pursue art, I think :) For what it's worth, I highly recommend Osti's Basic Human Anatomy. I wish I had seen it before learning about the Loomis method, etc.

Borysław Paulewicz @boryslaw.bsky.social · 23d

To me, this is theoretical (=scientific) *psychology* at its best. Thanks to these authors, we now know some new, fairly universal (abstract), undeniable (proved), and useful facts about *affordances*.

The term "gold standard" is especially popular in fields like psychology, where researchers are often unable to articulate valid reasons for taking their claims seriously. Mainly because they are mathematically illiterate. It is essentially an appeal to the "authority" of the research community.

Can large language models stand in for human participants?
Many social scientists seem to think so, and are already using "silicon samples" in research.

One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want.
