The truth doesn’t get less true because everyone around you is lying. It just gets lonelier.

Being outnumbered is not evidence, although it feels exactly like evidence while it is happening. A room agreeing on the wrong version can make you doubt what you saw with your own eyes, and the pressure to fold is mostly the pressure of standing alone. The fact does not change with the head count. The cost of holding it does.

Keep your own account of what happened somewhere private, in your own words. Find one person outside the group to say it to. And be the second voice when somebody else is out there alone, because the second voice costs far less than the first.
