I had a very successful "someone is wrong on the internet" interaction today, where that someone happened to be [checks notes] me.

In 2006, when Howard Stern moved from terrestrial radio to paid satellite radio, ClearChannel hired Penn Jillette to sort of take Howard's place (on the west coast).
On the very first episode, Penn was taking calls about a controversial subject and someone pointed out a fact that directly contradicted his stated position on the issue.
There was an awkward pause, and Penn said "Ok, that had not occurred to me, and I was wrong," and then proceeded to state his new (accurate) position.
As a longtime talk radio listener I was flabbergasted.
This was an extremely formative experience for me, because I instantly realized that Penn was actually happy about being proven wrong, and didn't even hesitate to throw his whole opinion out the window. (I could also practically feel the radio people screaming "what are you doing?!")
I made a concerted effort from that day forward to try to find joy in changing my mind about something.
I highly suggest this.
