Psychster Inc. built this site for researchers in a new field of psychology who study how well people read each other's personalities. We're wondering the same thing you are - what makes two people "get" each other? Or what stands in the way?
For decades, journals wouldn't publish reseach on this issue, arguing it wasn't valid. If this site is a success and lots of people use it, we're going to strip off all the names (and other identifying information) and tell the world what we learned.
Join the effort. Guess random people's personality. Invite your friends to guess yours.
