For me, it’s a matter of how little they know the world around them and how things affect other things. Case and point, when voters thought that voting Trump in, that he would magically make egg prices go down. They’re going down now, from what I saw shopping earlier today, but they weren’t because of him.
Another example is how when shop lifters, when they shoplift, always think that they’re harming who they call ‘The Man’ aka corporate operating the stores, directly. That’s not entirely true and I know this having worked retail several times and currently.
Who you’re hurting, really, is the store itself and those that work in it. The store pulls its own profits in by how many people shop there and part of that profit, is distributing to those who work there. When you’re stealing from that store, you are actively harming that store’s profits and in turn, harming those that work there.
The CEOs and executives are still raking in millions and they aren’t above having to shut down stores over dipshit thieves which in turn, costs a lot of jobs in that store to absorb the profits to make up whatever costs.
Intelligence is a difficult thing to measure, especially merely by interacting with a person for a little while.
Many of the answers in this thread amount to privileged assumptions that fail to account for the fact that what they describe as signs of lacking intelligence could also be symptoms of exhaustion and alienation inherent to conditions such as living under a capitalist system and/or neurodiversity and/or disability and/or sickness and/or…
For example, when someone works 16 hours a day for 5/6 days a week, they are far less likely to have the energy for using their little free time away from work to ponder deep questions at the same level as someone privileged enough to have a less demanding existence. This is not correlated with their intelligence in any way.
