New York Times helps promote book poorly reviewed by New York Times

In the past year, The New York Times Sunday opinion page has run three different columns by Moises Velasquez-Manoff, a writer whose new book argues that the hygiene hypothesis — the idea that over-cleanliness can make you sick — is the one true cause behind everything from autism, to celiac disease, to allergies. While the hygiene hypothesis, itself, is perfectly plausible, Velasquez-Manoff's extension of it to cover a host of hot-button disorders and cures for said disorders is much less plausible ... something that was pointed out in a negative review of his book that ran in, yes, The New York Times. Matthew Herper explores this strange dichotomy at Forbes.
