A bad idea doesn’t get safer because twelve people are doing it at once.

Numbers change how a thing feels, not what it is. A group makes a risk feel shared and normal, and each person quietly assumes that somebody in the room has checked, when in fact everyone is drawing the same reassurance from everyone else. The odds do not move because the company improved.

Ask yourself what you would think if you were the only one considering it. That question strips out the crowd and leaves the actual decision. If your only reason is that others are doing it too, you have found out something useful about the reason rather than the thing.
