In his fourth book, Everything Bad Is Good for You, iconoclastic science writer Steven Johnson (who used himself as a test subject for the latest neurological technology in his last book, Mind Wide Open) takes on one of the most widely held preconceptions of the postmodern world-the belief that video games, television shows, and other forms of popular entertainment are detrimental to Americans" cognitive and moral development. Everything Good builds a case to the contrary that is engaging, thorough, and ultimately convincing.
