Every now and then I see the mental blocks some people put up unconsciously, when they've preemptively decided they're going to disagree with new data.
Today someone mentally blocked out every identifying marker in a video I'd shared with them, so they could claim they didn't know who was in the interview.
But there was no *conscious* intent to their actions. Some deeper part blocked them from being able to recognize the interviewee clearly labelled all throughout.
Fascinating and disturbing.
