Let people change their minds without making them grovel. You’ll want that same room someday.

Charging somebody for changing their mind teaches everyone watching to never do it again. If a reversal costs an apology tour, people learn to defend positions they stopped believing in. You are also setting the price you will pay yourself, because you will be wrong about something in front of these same people. The room you leave is the room you get.

When somebody backtracks this week, say some version of fair enough and move straight on. No teasing, no bringing it up again on Friday. Making it boring to change your mind is how you get people to do it early.
