I used the race-intelligence connection as an example because it was the example used in Morendil's post to which this was a reply, which itself used it because it was the topic of the comment Morendil noticed was doing it wrong. I probably should have made this clearer; if you weren't following the history, it does look like a really really badly chosen example.

I personally have no strong opinion one way or the other. IQ is very hard to pin down genetically, seems to be distributed across hundreds of genes, and would probably be much harder to change than things like skin pigmentation or lactose tolerance. But generally I classify it in the category of "things whose political flammability is so far out of proportion to its actual importance that it's not worth thinking about unless you're itching for a fight".
