A compass that swings toward whoever is loudest isn’t a compass. It’s a weather vane.

An opinion that moves with the room is not an opinion, it is a reading of the room. The tricky part is that it feels like open-mindedness from the inside, and being genuinely persuaded is a good thing. The difference is whether you shifted because of the argument or because of the volume, and volume is not evidence.

After you change your view, check what moved you. If you can name the specific point that did it, you learned something. If you can only name who said it, wait a day and see whether you still agree.
