> But a factual controversy can also be costly, driving down sales and, in extreme cases, forcing the publisher to recall and destroy finished copies.
Are there examples of this happening? Michael Wolff's book was a bestseller, for example, despite many of the factual disputes coming up prior to its release.
In theory, lack of fact-checking would seriously hurt a traditional media outlet, as it could reduce traffic or subscriptions. For authors, however, it's not exactly the same calculus. Once the book is sold, it's sold (I realize it's a bit more complex than this with advances and returns, my point is that convincing someone to keep paying them monthly isn't a concern). Once they become a best-seller, they'll be able to put "best-seller" in their "About the Author" section. While there's a future credibility argument (which can be partially mitigated by the value of being a "best-selling author"), I'd argue that from a pure "maximize returns from this publication" perspective, there's really only an incentive to fact check things that are so egregious that it could lead to a recall or stop the book from being published in the first place.
This is not a good situation to be in, but the job a publisher is hired to do is to take a manuscript and turn it into something that can be sold in bookstores. I'm not really sure that it should be their role to police this, unless it's published by a media outlet explicitly as journalism.
