>If you're educated, high-IQ tiger parents and want to raise highly successful children, statistically you're better off having your own kids than adopting

This is the most depressing thing I read in this whole thread. The idea that one should view raising "highly successful" children as some kind of outcome they can control or influence through "high IQ tigerness" and cold economic analysis is humorous and sad all at once. Coupled with encouragement to not buck a pointless social tradition because it may make (shallow, deplorable) people judge you as less worthy and thus may negatively impact your future prospects of becoming more like them seems like a rather sad way to live life, but I guess we all have our own goals. The fact that after thousands of years our species is still mesmerized by shiny rocks we dug out of the ground is also odd to me, but apparently not others.
