“Accept reality”
Not all conspiracy theorists are dumb.
Some of them could be on to something.
But for the ones who are less intelligent it’s just that they only look for proof that they are right, and mostly ignore proof that they are wrong.
Take Friday the 13th a a metaphor for this. If you were someone who believed it was unlucky:
If you got fired from your job you would probably think it was the date’s fault.
But on any other day you would be ashamed at yourself or mad at whoever fired you.
