Can you point to specific parts of that post which are in error owing to ideologically motivated thinking?
A piece of writing biased for ideological reasons doesn’t even have to have any specific parts that can be shown to be in error per se. Enormous edifices of propaganda can be constructed—and have been constructed many times in history—based solely on the selection and arrangement of the presented facts and claims, which can all be technically true by themselves.
In areas that arouse strong ideological passions, all sorts of surveys and other works aimed at broad audiences can be expected to suffer from this sort of bias. For a non-expert reader, this problem can be recognized and overcome only by reading works written by people espousing different perspectives. That’s why I recommend that people should read Shalizi’s post on heritability, but also at least one more work addressing the same issues written by another very smart author who doesn’t share the same ideological position. (And Sesardić′s book is, to my knowledge, the best such reference about this topic.)
Instead of getting into a convoluted discussion of concrete points in Shalizi’s article, I’ll just conclude with the following remark. You can read Shalizi’s article, conclude that it’s the definitive word on the subject, and accept his view of the matter. But you can also read more widely on the topic, and see that his presentation is far from unbiased, even if you ultimately conclude that his basic points are correct. The relevant literature is easily accessible if you just have internet and library access.
