"Dan Ariely argues that, to understand the irrational appeal of misinformation, we must first understand the behaviour of 'misbelief': the psychological and social journey that leads people to mistrust accepted truths, entertain alternative facts, or embrace full-blown conspiracy theories. Misinformation, it turns out, appeals to something innate in all of us, and it is only by understanding this psychology can we blunt its effects."--Back cover of paperback edition.
