Okay, you have a hypothesis. It seems a little unlikely, but I agree that it could be true.
Now, let's get to the proof side of things. What evidence makes you think this is a good explanation for the range of phenomena that you see? What else does it explain? Why can we discount other explanations, etc.
When it comes to social science, there is no one single comprehensible good explanation for the vast majority of phenomena - what I was pointing out is that there are systematic biases when comparing "adopted Asian Americans" and "Asian American immigrants". These biases - financial, psychological, etc - will have a significantly larger influence on how children perform than what you're testing for (genetic differences).
Only they don't, because when you measure it, you can predict 80% (studies differ on the exact number) of IQ from parent's IQ. The rest is mainly unshared environment (what we don't know how to fix).
Oh hey, I remember you from last time. No, I'm a number of years past that age.
I am a little depressed to be arguing with people who think that calling names is a valid way to argue this sort of thing. The closest I've gotten to a real intellectual response is someone who claims that thinking you're Asian will make you better at math (alert the schools of this discovery!).
I thought that Hacker News was a place where intelligent people were willing to hold intelligent discussions. If you're going to talk about immigration (which HN wants to talk about a lot) you have to consider this sort of thing at least.
Instead, what I see is the view: "On this subject it's okay to turn off our reasoning facilities." Why? I guess because thinking about it would be wrong. You'd have to be a Nazi to know about the Hapmap data or brain genes that vary across population groups like ASPM and microcephalin. Ah well.
Maybe I should begin attacking people for being dirty culturists instead. Attacking African culture, claiming that it causes IQ drops, is a terrible slander against what are sometimes a very beautiful set of social systems. Only evil people could claim that.
Now, let's get to the proof side of things. What evidence makes you think this is a good explanation for the range of phenomena that you see? What else does it explain? Why can we discount other explanations, etc.
