Everything's quite new here at #bsky, so perhaps a quick intro could be useful.

Oops, something fishy with the silver medal-winning photo of barn swallows, reward was removed last week. This photo from the competition Bird Photographer of the Year has disappeared from many sites, but has remained on this site (so far):

Same opinion here! Academics no longer engage in critical thinking, and their views are anything but intellectual. I'm old already, though and grumpy, especially about this.
I think this is true in a deep and troubling way. I have been observing this too. I am getting old & maybe I’m wrong, but I really feel basic academic, critical and intellectual, attitudes that were normal and prominent 20 years ago seem to have eroded. I agree, we need to understand how and why.
The scenario in which there are oligarchs powerful enough to succeed at their AI con and force LLMs onto the rest of society is the outright fascist and dystopian scenario. That higher ed has largely capitulated to the scam means it had already been deskilled. We need to understand how and why.

Your Genes Are Simply Not Enough to Explain How Smart You Are
Seven years ago, I took a bet with Charles Murray about whether we’d basically understand the genetics of intelligence by now.

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 The innate versus acquired dichotomy is outdated and has been for a long time.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.
