CNN reports, in huge big black letters: "Older mothers' kids have higher autism risk, study finds."
Eleven paragraphs in: "The study authors emphasize that while autism rates have risen 600 percent in the past two decades, older women having children contributed to only 5 percent more cases of autism." Emphasis mine.
Nowhere does the article make any effort to distinguish between an increase in autism and an increase in the diagnosis of autism.
Who cares anyway. Mothers suck. That's the important thing.
