I've observed that no matter what a study says, there will be people on HN contradicting it, no matter how ridiculous.
Humans can't tickle themselves? I can.
Humans think in pictures? I don't.
Humans don't remember the moment of their birth? I do. (Followed, of course, by "I thought this was normal").
Do people lie out of defiance, or to make themselves sound like special snowflakes, or what? Is there a term for this?
