Every objection that has been posted thus far to Saletan's article is addressed in the articles that he links to the text. Clearly environment matters in the case of IQ. But all of the objections around culture, nutrition, education, parenting and such being the sole determinant of IQ are addressed and countered with a tremendous amount of evidence.

It appears no one here actually read any of the articles he linked to and then criticized him for not providing sources.

I have recommended your post more for these statements than for anything else, although I'm sure you meant "every" to stand in for "almost every scientific" (i.e. there have been objections posted relating to what this all means, rather than if it is scientifically valid).

I take your general point about posters not following the links, and this is a chronic problem I've found with this forum (i.e. the Human Nature Fray). For his part, Saletan's problem is that he doesn't always sufficiently group concepts within paragraphs such that it is made obvious to the reader where he got his information. But yes, it would certainly benefit this board (and make Saletan's life easier) if people would dig a little deeper into his articles before posting.
