When it comes to computers, people either understand them or don't, and everyone is fine with it. When it comes to math, people never pretend to be good at it – most readily admit they aren't. Yet when it comes to "softer" issues, people who have no clue what the hell they are doing think they are experts. Why is that? Good ideas do come from outside sources and novices, but why do people who know nothing about marketing assume they are experts? Politics is the same way. Why can't people acknowledge that they know as little about some of the "soft stuff" as they do about the hard sciences?
