Disclosure doesn't excuse a conflict

[yendi]

From today's New York Times review of Blake Bailey's memoir, by Janet Maslin:

The writers Richard Yates, John Cheever (my father-in-law) and Charles Jackson, who wrote what he knew in his novel “The Lost Weekend,” all spoke to Mr. Bailey’s own turbulent background.

Um?

I'm sorry, but if you're reviewing a book by someone who wrote a book about your family, it's a conflict of interest. Period. Dicslosure does not make it right, and the Times has more than one person who can review books.
