Only on the "CBS This Morning" podcast, the authors of "Meltdown: Why Our Systems Fail and What We Can Do About It," Chris Clearfield and Andras Tilcsik, discuss their book with "CBS This Morning" co-host John Dickerson. Whether it's Thanksgiving or Three Mile Island, Clearfield and Tilcsik argue it is important to have systems in place that do not lead to a failure. They introduce us to the terms of loose and tight coupling. The two authors say the need for skepticism and a group of truly diverse people are needed to ensure complex systems do not fail. They say the 2017 Academy Awards Best Picture mix-up is an example of how safety features actually add complexity to a system.
