Only if it actually matters, or if very little time has passed, and only if I have previously demonstrated that I’ll also go back unprompted and admit to being wrong. And I’ll prefer to demonstrate good behaviour and pointing out when I’m being wrong multiple times before pointing out when others were wrong.

Others need to know I’m not going to be a dick about it and I’m just looking for truth in either direction, so they don’t feel personally attacked or defensive.

It also depends highly on the topic and my relationship with the other person.
