Accountability

Some people try to force others to believe.

Appearing to believe can be a manifestation of fear, or a need to fit in. Fitting in is evolution in action. Herds, packs, flocks, schools, all rely on it to protect the whole, so people who acquiesce without really believing are common.

People who stand up for the truth and don't just pay lip service to the herd must be very brave.

Or very strong.

Or very stupid.

And fear of looking stupid is very strong in many people.

Everyone makes mistakes, or has accidents. The difference lies in how people respond. The honest ones admit it and learn from them.

The others will pretend you are the bad one, because God forbid they should take responsibility for their own actions. They might be held accountable.
