I figured some of you who read my blog might be hanging out over here. Feel free to mail in tips or stories during the week, and I'll try to get a post up every Saturday. Why, it’s fun to be back!

Welcome back. Regarding the study that you mention, which finds that scores were higher for Asian, black, and Hispanic students whose friends were of different ethnicities - this looks like junk science to me. Selection bias is a tremendous problem in studying friendship choice. The researchers ignore this problem and instead simply divide students into two groups - those whose best friends were of the same race and those of a different race. Isn't it likely that students with different race best friends are different in some way that also affects their achievement trajectory - i.e. they're in higher track courses, which tend to be more integrated?
