Nick Punt, observing that on social media “it is far easier to escalate than it is to de-escalate”, proposes a pretty fantastic new Twitter feature: the Mea Culpa. (I’m sorry; I’ve lost where I found this.)

Twitter Mea Culpa is a way for a poster to flag their tweet as a mistake and de-escalate a situation, using the same action menu that deleting a post uses, and the same visual design as flagged tweets[.]

By admitting a mistake, the poster stops the runaway train of replies and amplifications of their mistake, and the reputation damage that follows. In other words, Mea Culpas are intentionally designed to favor respectful debate and ability to cool off over maximal information exchange.
