🧠💡 This feat of study by Kasper Otten and colleagues analyzed 1.5M decisions from 135K people in online public-goods games. Takeaway? When group membership changes (people leave, newcomers join), cooperation drops. Stable groups = stronger cooperation.

When we see something that's moving, our memories about it end up projected forward in time: We remember it further along than it was.

S1: More social media users perceived themselves as addicted than met clinical addiction criteria.

S2: Increasing perceived addiction hurt perceived control over use and increased self-blame for overuse.

Nearly every mechanism that made my career possible—Ford, NSF, Harvard BiGS—is gone or on the way to the chopping block.
This means NSF dissertation improvement grants in the social sciences are simply...not happening.
NEW from me - NSF cancels grant scheme for social science research.

Seems the NSF quietly archived ALL calls for DDRIG grants in the SBE directorate. This is a massive blow for PhD students wanting to do cutting-edge social science research. 🏺🧪

We reviewed 263 studies on racial & ethnic prejudice measures. Most are psychometrically weak and conceptually narrow. Only 4% meet high-quality standards. We call for rigorous, theory-driven, culturally sensitive tools.

We have a new paper in Science Advances proposing a simple test for bias:

Is the same person treated differently when their race is perceived differently?

Specifically, we study: is the same driver likelier to be searched by police when they are perceived as Hispanic rather than white?
