New research in Rwanda has started ! We continue to try to understand what differs those who participate in a génocide, and those who instead risk their lives to save others.
Here is a picture of our novel and ecological risk-taking task, inspired by the BART.

How does the brain decide? 🧠
Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc.
After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up.

Why do cars have a 3rd brake light
When you hit the brakes, the car’s brakes will flash to warn following drivers that you’re slowing or stopping. Without brake lights, our roads would be chaotic and deadly.

Now lets hope we see a similar noticeable improvement in theory building and measurement a decade from today. To the people working on that challenge: it is good to see change is possible!

The proportion of p-values between .01 and .05 declined in psychology over the last decade, a strengthening of credibility.
Papers with fewer fragile p-values are cited more. Higher ranked journals assoc. with > improvement, but not higher ranked universities.
