Fundamental attribution error. Wanting something to happen ≠ believing it should happen. When wanting becomes believing, you are fucked.
Too many people think that the world should bend the laws of reality to conform to their ideas. Gamblers are the prime example. They take something solvable by pure math and completely discard the solution, opting for a solution based on their wants instead of reality.
I think you're conflating a fundamental attribution error with a some other cognitive bias.
The fundamental attribution error refers to an individual's tendency to attribute another's actions to their character or personality, while attributing their behavior to external situational factors outside of their control. In other words, you tend to cut yourself a break while holding others 100 percent accountable for their actions.
It is amazing to me that millions of idiots whole heartedly believe in some variant of magic/placebo/prayer/astrology, some very slightly different version of it becomes popular when someone figures out some new lingo that sounds neat, and can lie convincingly in a video.
