Literature

The author of a nonfiction book about the effects of artificial intelligence on truth acknowledged on Monday that he had included numerous made-up or misattributed quotes concocted by A.I.

The author, Steven Rosenbaum, whose book “The Future of Truth” was released this month to great fanfare, incorporated more than a half-dozen misattributed or fake quotes in sections of the book reviewed by The New York Times.

The Times asked Mr. Rosenbaum about the quotes on Sunday and Monday. On Monday night, Mr. Rosenbaum acknowledged in a statement that the book had “a handful of improperly attributed or synthetic quotes” and said that he had started his own investigation.

He said that the inclusion of the incorrect quotes was an accident and that he had “no intention of fabricating any viewpoints” while writing the book.
