One of the best ways to promote the pursuit of truth is to not be melodramatic when people make mistakes and sincerely own them.
“We all make mistakes” > “Ha, I told you so”
“What matters is that you understand where you went wrong and how to fix it” > “You just got owned”
Praise people for being honest instead of bashing them for having flaws and imperfections that they need to be honest about.
Discovering our errors is a beautiful thing. How beautiful would it be if we didn’t make people feel ugly about that?
