🚨NEW PAPER 🚨 Are police more right-wing and biased against marginalized groups than the general public? If so, why? My new article in @PNASNews w/ Reny, Newman, and Sears provides some answers. 🧵1/n

🚨New paper in @TrendsCognSci 🚨

Maybe the most powerful figure I’ve seen this year: the racial gap in tickets from speed cameras vs. officer stops.

Doing good science is 90% finding a science buddy to constantly talk to about the project.

An common form that discrimination takes, which is often hard to spot: when people from underrepresented groups make a mistake, the response to it is often harsher than for someone from the dominant group

Once, we ran a study on Prolific and a participant wrote on Reddit that the study “Felt like I was losing the will to live.” I went on the Prolific Subreddit (24k members!) and asked what matters. Here is what they told me. A thread on happier participants and better studies 1/9

I’m sad about the loss of my amazing mentor, Frans de Waal. Perhaps take this moment to consider how science improves when you step back from cute effects and just observe natural phenomena. Be curious. Consider what we misunderstand. Then test. Share out.

It's time to stop dumping thankless tasks on women.
Women get more asks than men to serve on committees, plan events, and take notes. They're more likely to be penalized if they say no—and taken for granted if they say yes.
Work should be divided equitably by role, not gender.

People on average keep their secrets for years (mean=9, median=5). Can you experimentally create this typical kind of secret? No. So what can you do? See our new paper! How can we learn about experiences that cannot be recreated in the laboratory? columbia.edu/~ms4992/Pubs/20…

By mapping the meanings of the words used to communicate emotions across more than one-third of the planet’s spoken languages, a study in Science found that there is significant variation in how emotions are expressed across cultures. #ScienceMagArchives scim.ag/5KJ

Woohoo! My paper with @jenniferdoleac is (finally) forthcoming at AEJ:Policy.
We look at what happens when human judges are given algorithmic risk assessments to help determine who to incarcerate. 1/
