A thing in a book I read.

I'm so glad you posted this. I saw it in college, and haven't been able to find it since. What's the book?

It was from some psych class, but I don't remember exactly which one. I've sold most of my school books, but I'll check to see if I hung onto it.

Kassin & Fein have a good social psych textbook that explains the theory quite well.

I like. It's a good measurement of how things are going along in so far as a dating scheme too.
