I'm worried about outsourcing to a machine something that's part of our common endeavour to figure out the world. It's not enough that stuff is figured out, it's about **us** figuring it out! I don't remember phone numbers anymore – I outsourced that to my phone. I don't want that for my science.

this figure from 1944 is cited as the first topoplot, from Koiti Motokawa. in an era where only handful of EEG channels across space were used, he measured the mean alpha amplitude for 90 points across the scalp. ❗

1/8 Numerical cognition in birds
They handle quantities, proportions, simple arithmetic, etc.
The numerical cognition of birds is similar (sometimes superior) to that observed in primates, which represents an astonishing evolutionary convergence.

A cautionary tale for PhD's from lower-income countries who are on "stipends": often regarded as disposable, their vulnerability (precarious access to healthcare, social security, etc...) makes them prime targets for a "flexible" form of abuse that hides in plain sight. Let us not normalize this👇
