That's an interesting thought. I wonder if you can quantify this belief? That Weibull (presumably) distribution would be an interesting and useful thing to know.
But if you don't see how people yearn to believe in big dramatic things like conspiracies, aliens, bigfoot, or even simple narratives about single people changing the course of history, and how they only accept the complicated and/or boring reality with conscious effort, then, well, you seem to be living in a better universe than I am.
At least in the case of things like migrations, we're starting to get overwhelming genetic evidence.
