Everybody has beliefs. Many are so deeply ingrained that we do not even recognize them as such. The most staunch scientist—who spurns belief in Santa Claus or God—still operates on a metaphysical foundation of beliefs about how the world works: e.g., that the scientific method is the only valid path to truth, and that unproven conjectures have little worth—and unprovable ones even less—even if quite possibly correct (and important). For instance, science can probably never tell us if animals experience emotions the way humans do, but isn’t it obvious by non-scientific interactions? Maybe some animals experience a sense of awe for natural phenomena, or notice the stars and wonder, or are more aware of their own mortality than we could ever know. Plants “scream” when attacked; will science ever deliver an understanding of what it is like to be a tree? How could it?
But I digress, already. This post is not about the narrow, literalist, and almost certainly incomplete metaphysics of science, but about the stubbornness of brains. People have a very hard time getting rid of some notions, or accepting something that runs counter to their assumptions. One might even suspect some “hard” wiring at play! Hey wait—people’s predispositions, personalities, and beliefs must indeed map to real neural connections in their brains (where else: we don’t use cloud storage!). Changing minds means down-weighting or destroying some connections and making new ones: not easy. Incomplete attempts often “repair” themselves back to something close to the original state, as beliefs are woven into so many offshoots as to be difficult to eradicate fully.
But neither is this a post about brain functions. Come on, Murphy, get it together! What this post is about is how intransigent people are, in general. After a few familiar examples, we’ll turn an important case: people have a very hard time seeing how unusual and temporary this moment is, it having lasted all their lives and more. The claim that most humans don’t appreciate the obvious temporary nature of modernity might seem as dismissive as the claim that animals don’t appreciate their own mortality. Yet some can, and that’s very important.
