In The Chicago Guide to Fact-Checking, Brooke Borel, an experienced fact-checker, draws on the expertise of more than 200 writers, editors, and fellow checkers representing the New Yorker, Popular Science, This American Life, Vogue, and many other outlets. She covers best practices for editorial fact-checking in a variety of media-from magazine and news articles, both print and online, to books and podcasts-and the perspectives of both in-house and freelance checkers. In this second edition, Borel explores the evolving media landscape, with new guidance on checking audio and video sources, polling data, and sensitive subjects such as trauma and abuse. The sections on working with writers, editors, and producers have been expanded, and new material includes fresh exercises and advice on getting fact-checking gigs. Borel also addresses the challenges of fact-checking in a world where social media, artificial intelligence, and the metaverse can make it increasingly difficult for everyone-including fact-checkers-to identify false information. The answer, she says, is for everyone to approach information with skepticism-to learn to think like a fact-checker. The Chicago Guide to Fact-Checking is the practical-and thoroughly vetted- guide that writers, editors, and publishers continue to consult to maintain their credibility and solidify their readers' trust.
