A mistake made in public does not require every witness to contribute a verdict.

Visible mistakes attract commentary out of all proportion to themselves, because each person adding a view believes theirs is one of only a few. The weight lands on someone who already knows precisely what happened and has known since the moment it did. Restraint leaves no trace, which is why it feels like nothing.

When you watch somebody fail publicly, notice the pull to weigh in and let it go past. If you know them, send something private that is not about the mistake at all.
