"On the whole, the research shows, conservatives desire security, predictability and authority more than liberals do, and liberals are more comfortable with novelty, nuance and complexity. If you had put Buckley and Vidal in a magnetic resonance imaging machine and presented them with identical images, you would likely have seen differences in their brain, especially in the areas that process social and emotional information. The volume of gray matter, or neural cell bodies, making up the anterior cingulate cortex, an area that helps detect errors and resolve conflicts, tends to be larger in liberals. And the amygdala, which is important for regulating emotions and evaluating threats, is larger in conservatives."

Facebook/Meta is the latest organisation to claim they can use AI to 'read minds' via brain activity. But both such claims and the fearful reactions seriously overlook how tricky the brain makes this.

Dean Burnett's latest post looks at how neuroscientific misunderstandings lead to dubious media coverage.

Humans have been hunting for sex-based differences in the brain dating back to at least ancient Greece. Yet a scientist observing a female and male brain in a lab can’t tell them apart. "I'm not aware of any measure you can make of the human brain where the male and female distributions don't overlap," Dr. Armin Raznahan told Live Science. That said, the question of how male and female brains differ may still matter. @LiveScience has more:

I'm a neuroscientist. Here's the surprising truth about TikTok 'brain rot'.

‘Brain rot’ was named Oxford's word of the year for 2024, defined as the "supposed deterioration of a person’s mental or intellectual state" resulting from watching too much "trivial or unchallenging" content online, such as TikTok videos.

A recent study suggests bingeing short-form videos is bad for your grey matter.

Vox: Is AI really thinking and reasoning — or just pretending to?. “The big story is: AI companies now claim that their models are capable of genuine reasoning — the type of thinking you and I do when we want to solve a problem. And the big question is: Is that true? The stakes are high, because the answer will inform how everyone from your mom to your government should — and should not […]
