Owning your fumble out loud makes it safe for everyone else to own theirs.

Whether mistakes get admitted in a group depends almost entirely on what happened the last time one was. When the person with the most to lose says plainly that they got it wrong, the cost of admitting things drops for everyone below them. Concealment is not a character flaw in a team; it is a response to conditions.

Name your own error before anyone else has to raise it, in one sentence, without decorating it. Say what you are changing and move on. The point is not the confession; it is the permission it creates.
