In a wide-ranging interview on Masters in Business, Ray Dalio – the super successful investor – said this about opinions while discussing his process question, “How do I know I’m right?”:

BARRY: When should you not have an opinion?

RAY: Well, a lot of times, right? I mean, opinions – particularly in any – is a zero sum game. So many people have opinions that they’re attached to, and they don’t know whether they’re right, and that bias is killing them. I think one of the greatest tragedies of mankind is people stupidly holding on to opinions that could be wrong, that they could be so easily put out there and stress test, and that emotional attachment to these opinions is one of those things, where instead you could just say, let me get the best thinking I can have, it doesn’t even have to come from me. Why does it have to come from you?

Although it’s an investing/money podcast, the interview should be valuable for just about anyone since it’s primarily process-oriented, with concepts that apply to just about everywhere else.
