Former First Lady Jill Biden’s memoir, View from the East Wing, debuted at No. 1 on the New York Times Hardcover Nonfiction bestseller list on June 21. But how much of its sales were genuine sales from interested readers is unclear.

In fact, when the book appeared on the bestsellers list, it came bearing a dagger (†) symbol, the small mark the Times attaches when retailers report bulk purchases mixed in with regular sales. A book doesn’t earn that symbol by accident. It earns it because the paper suspects something other than organic demand is propping up the number.
Whatever propped it up didn’t hold.
The book slid to No. 3 the following week, then vanished from the list entirely. Circana BookScan, the retail data source most of the publishing industry actually trusts, tells an even blunter story: the memoir dropped from No. 2 to No. 5 to No. 16 on its hardcover nonfiction chart across successive weeks. By the week ending June 20, it had moved just 3,221 print copies, bringing its total U.S. print sales to 29,539. For a book marketed as a cultural event timed to a midterm cycle Democrats are already sweating over, those numbers look thin.
Statistician Nate Silver, the founder of FiveThirtyEight, noticed the pattern immediately.
