These Are Twitter’s Biggest Secrets
TIME: What makes us follow, fave, share and—most importantly—keep coming back When I choose someone new to follow, when I compose a new tweet, when I share and favorite an update, I seldom think about the why.

New Research From Psychological Science
Read about the latest research published in Psychological Science: Young Children Bet on Their Numerical Skills: Metacognition in the Numerical Domain Vy A. Vo, Rosa Li, Nate Kornell, Alexandre Pouget, and Jessica F.
