Is this actually true? It's one of those bits of "telephone wisdom" I've heard passed from commenter to commenter on Hacker News (and Slashdot before that) for as long as I can remember, but nobody ever seems to have a primary source for it, it's always been a "just trust me" bit of knowledge.

It isn't true. Advertisers think in broad social groups. ("25-44 women with kids", "men with college education", etc.)
