I suspect a lot of people have difficulty recognizing that what they believe about the world may not be representative of how the world actually behaves. I certainly do, frequently.
Like with politics, people think they need to go vote and march and stuff to effect change, but if you're willing to accept the idea that there are limits to your ability to perceive the world and your perceptions are misleading, you can pretty reliably go and see that isn't true.
You can also decipher deeper realities like you can basically put whatever you want on flat bread, or that you dadskf;'akse'wfaegqrwt;'lj'a fuck my brain. I'm asd I'm not sure what I was trying to say.
Along those same lines, I'm always bothered when in movies, there's a seemingly unstoppable evil that the people can't kill, then a little girl spills some water on one of the beasts, and it works. Word spreads and there's a montage of people in the US, France, India, China etc spilling water on the creatures and winning. Like, motherfucker they are organic beings! There are hundreds of ways to kill them!
Also, the "we tried something once, and did a bad job at it, so we won't try it again" movie trope.
