&gt; However I have tried to point out that the evidence doesn&#x27;t lead you to this conclusion since other variables may correlate (...)<p>They may correlate, but genetic is by far the biggest driver. Identical twins (same DNA) have between 0.76-0.86 correlation between their IQs. The 0.76 is raised separately; a completely different environment and they are still almost identically smart!<p>The other numbers you&#x27;ve written are the effect of moving away from perfectly identical DNA.
(You could argue that part of the difference is cultural, but that doesn&#x27;t change anything if we don&#x27;t know which part of the culture is negatively impacting the child.)<p>&gt;because assuming regression to the mean, if I pick a 160IQ black woman and a 150IQ white man, we&#x27;d expect their kid to be centered around 155, regardless of race.<p>No, see my Japaneses example. Two geniuses of 160IQ will most probably have children returning closer to the mean (tho probably a little higher). In this case, the mean is different for every race.<p>If I&#x27;m a white with a IQ of 100 and I have a child with a black with a IQ of 100, the expected result <i>is not</i> 100, because the black is an outlier at this IQ.<p>&gt; Nonetheless you have repeatedly brought it back to race, which means that this is tremendously important to you. On that topic I&#x27;m curious why. You&#x27;re probably pretty intelligent (though introspection is a skill separate from observing the outside world), so I have high hopes for a good analysis ;)<p>I do too. :-)<p>I brought race because that was the topic at hand and because we are talking biology here (reproduction).
Obviously &quot;white&quot; isn&#x27;t my only criteria. I could speak at length how I like girls with a fighting spiring, but that&#x27;d be a little out of context.<p>Like I said in a parent post, my previous position was pretty much &quot;all races are the same&quot;. It took -months- before I really changed that. What really prevented me from accepting the various studies was the survivor bias: All the individuals from the other races I ever saw was on TV. Actors, political commentators and such. If they got their job, it&#x27;s because they were good. I wasn&#x27;t looking at the average here.<p>The same apply for people of the same race by the way. Many people of IQ 120+ went to university and their entire social group is composed of smart people. They don&#x27;t realize (and can&#x27;t conceive) that a huge part of the population is less intelligent.<p>------<p>&gt; I am aware that white men have the highest suicide rate of all races, so there&#x27;s something going on there.<p>I have no clue why that is, but I&#x27;d very much like to know.
