>It’s amazing what happens when you become open to the best ideas, rather than the most credentialed voices. Is it though? For starters, you're going to have to listen to a lot of terrible ideas, which is time-consuming even if ideas are easy to evaluate (like jokes). If we're talking business strategy or science or technology, ideas can be very difficult/expensive/time-consuming to evaluate, credentials serve as a useful filtering step[0]. Next time the author has a health problem I suspect they'll go to a credentialed doctor rather than polling random people on the street. I agree that smart people can be overconfident, so it's good to have some humility, but it's also good to try to spend time effectively. And dumb people are perfectly capable of being overconfident as well, it's not like this is a problem unique to smart people. Ignorance can breed overconfidence just as much as knowledge; it's easy to "solve" a problem when you don't actually understand why it's difficult in the first place and your solution never gets tested against reality. [0] The extent that this is true is also a way to judge the credentialing system. Most areas have informal "credentials" based on experience/reputation, eg Jerry Seinfeld and Larry David are considered authorities on comedy and it's not because they have PhDs.
