There’s a reason why most anti-social, violent behavior is carried out by people in the lowest IQ groups. Low IQ means you can’t appreciate or predict consequences. It means you don’t know how to create mechanisms to keep impulsivity in check or that you don’t even know why it’s necessary to do that. It means you can’t comprehend the perspective of other people or figure out that it exists and that it’s different from yours.
Low IQ means experiencing a constant, daily, grinding frustration because people around you keep saying and doing things that you just don’t understand. If you ever traveled to a foreign country where you don’t speak the language, that’s how a low-IQ person feels always. Like you are in a group where everybody understands the in joke except for you. Living like this eats up so much energy that very little is left to control the already very weak system of checks over one’s impulsivity.
A low IQ is not anybody’s fault exactly like one’s height or eye color aren’t. It’s not a moral flaw. It’s a physical reality and denying it doesn’t help. It’s not kind to pretend that people don’t exist who under no circumstances will be able to perform the cognitive operations that we carry out without noticing.
The only real kindness is to recognize that this is real, it’s not anybody’s fault, and we need to help low-IQ people to handle their largest problem which is impulsivity. There are many completely physical factors that weaken impulse control. Processed food, sugary beverages, light pollution, certain types of medications, disordered living. Interestingly, people who have pretty excellent impulse control avoid all of this on their own initiative.
The saccharine pieties of the quoted tweet are completely counterproductive. Because we collectively refuse to accept the physiological reality of intelligence, we make things a lot worse than they need to be. Think about the students who have been told their whole lives that you can only flunk out of college if you don’t try hard enough. They try their hardest and still have absolutely no idea what the textbook is saying. They end up feeling terrible when this whole time they had as much change of understanding the textbook as I have of reaching the top shelf of my kitchen cabinet without climbing on a chair. These are people who get into debt to acquire an education they will never be able to complete. We are defrauding them. I recently saw the statistics for people with college debt and no degree. It should be criminal to do this to people.
