Only on the "CBS This Morning" podcast, co-host John Dickerson talks to the authors of a new book who suggest the culture of safe spaces and trigger warnings on college campuses is limiting students' intellectual development. In "Coddling of the American Mind: How Good Intentions and Bad Ideas are Setting Up a Generation for Failure," authors Greg Lukianoff and Jonathan Haidt argue that by purging campuses of ideas, subjects or even people who they may not agree with and make students uncomfortable is doing them a disservice. They join Dickerson to discuss why parents should shelter their children less at a young age and they make the case for why we need to be more intellectually humble.
