One of the most aggravating things to me in this world has to be the absolutely rampant anti-intellectualism that dominates so many conversations and debates, and its influence just seems to be expanding. Do you think there will ever actually be a time when this ends? I'd hope so once people become more educated and cultural changes eventually happen, but as of now it honestly infuriates me like few things ever have.
It's not so simple I think. Anti-intellectualism is a symptom of the greater human condition. Part of it is the scapegoat aspect. If something has a name then it's easy to point a finger at it, easy to blame the person who named it. Part of it is envy, people trying to tear down those who they feel are superior to them. Part of it is propaganda, if not caused by certainly exacerbated by.
Like many things in life it's complicated.
You forgot laziness. Intellectualism is difficult, and letting your emotions do your thinking is super easy. Then there's the greed, or more accurately the greedy, who will use anti-intellectualism to get what they want from others, be it money, power, or something else.
I maintain that it's pretty simple, actually. Humans are animals, just like any other. That comes with irrationality baked in. We think we're so much better than, say, orangutans, but are we really? I'm not impressed. I often think about how we would behave if we didn't have language or opposable thumbs. I realized one day that all we have to do is observe traffic.
I mean, the thumbs help hold stuff, sure, but it's our large pre-frontal cortex that really comes in clutch. That and our penchant for violence. There's evidence to show that the Neanderthals were possibly more advanced than us before they "died out," but also less violent and selfish. It's those traits that led us to kill them or cut off their access to resources while we took them all.
We are still animals. Any biologist will tell you that, but that's not a negative thing, it's just a facts. It's like saying we're mammals. It really comes down to how you define "better." and "successful." Obviously, we are making those determinations from our point of view, so we tend to define them with the things only we do. But if we're defining successful by technological advancement or the ability to do advanced math, or even versatility in abilities, we're at least top 3. But those orangutans are pretty nifty with their use of twigs sometimes, so don't count them out.
