A Constrained Vision has a series of quotes from Roland Fryer on “acting white”, meaning getting good grades and how that effects the number of friends you have.
low grades = no effect on friendship
higher grades (for whites) = more popularity
higher grades (for blacks) = same number of friends at 2.9
higher grades (for Hispanics) = least number of friends
Thus the perpetuation of poor academics among minorities. If you want to do well for yourself, you have to be willing to risk losing your friends.
