Interesting that females go toward someone of their own ethnic/cultural group (except for East Asian women who are neutral) and males are indifferent to the group of their would-be partner. It's like men are still spreading the seed far and wide, and women seek to avoid the raping conquerors.

"economists marry economists, probably not because they actually prefer to do so, but because those are the people they meet in daily life."

That pretty much sums up my feelings toward economists as well.

Did they really have to apologize for their part in dispelling mystery? :/
