The President of the United States just called for Democratic members of Congress to be executed. "HANG THEM", he posted.
If you're a person of influence in this country and you haven't picked a side, maybe now would be the time to pick a fucking side.

How foragers depart from optimal models can tell us a lot about how they compute their decisions.
A strong but underexplored departure is that foragers widely vary when they leave identical patches.

This paper is amazing. I saw Henry present these ideas Summer of '24 and it was mind-blowing. Someone needs to put a force-meter on the NHP headposts!
Really interesting work by Bakhurin and colleagues challenging the reward prediction error hypothesis of dopamine:
www.nature.com/articles/s41...
I love this figure which both echoes and undermines the famous figure from Schultz et al. (1997).
