I found this Psychology Today article which talks about “mind-reading” or just reading emotions, especially through eye cues.
I score pretty high on the “Asperger’s Quotient” test, which you can find various places. I’m not sure if I can read people well or not. I’m pretty intuitive, but don’t feel like I can predict people’s behavior. The important thing is probably to concentrate on what people are feeling, and what they want to do, rather than what they are thinking and what they should do.
