It’s true, I was reading some psychological website the other day and yes, there are some people who will not believe some things even if you have proof on video. They will deny it ever happened and call you a liar.
Of course we’ve all seen this in religious circles, but this was talking about secular things, not religion.
They will close their minds to whatever you are trying to convince them of and ignore your proofs because it does not fit their preconceived notions.
I saw this personally.
My younger brother was not a good person, always in trouble with the law from the time he was six. He was diagnosed as a sociopath by psychologists when he was about 12 or 13.
When he grew up he became a gigolo in South Florida, and preyed upon wealthy older women. He was apparently good at it, since he could lie with a straight face and make them believe anything.
Eventually he left there to seek other victims elsewhere. He never stayed anywhere very long.
We would get calls from these women trying to find him and they would not believe us when we tried to tell them what he was. He apparently had told them he was raised by really evil people who beat him and stole all his money and mistreated him all his life.
These women were absolutely enthralled by him, and wanted him back. We could not convince them they were victims of a con man! They thought we were the con artists!............
