I'd say the cost being wrong depends on the people. For a lot of people being in the state of unknown is better than random guesses with 0 expertise. Not everyone like to flaunt their ignorance

Not sure why r u so insist that only your way is right. That's ur choice of course

The fear of being wrong is a crippling one that haunts ineffective people. Effective people don’t care, because they know they can update their beliefs when new information is introduced.

You’re talking about pride. Prideful people are not effective.
