There’s nothing inherently wrong with having low intelligence. Sure, the person may have their fair share of difficulties, particularly when it comes to solving complex problems or managing daily tasks, but a lack of brainpower isn’t morally offensive.
It only becomes an issue when the individual in question comes off as obnoxious about their intellectual flaws. Like when they use TikTok as their primary source of information, refuse to hear other opinions, or the many other examples people shared in this recent Reddit thread.
If you think there are other things worth mentioning that aren’t on this list, feel free to add them in the comments below.

They are unable to understand that personal experience is not viable argument for wider and nuanced problems.
There was politician who literally said she does not believe poverty exists because “I was from poor family and we always had huge Christmas meals”.

When they try to make a point by just repeating themselves louder and louder.

When they can’t admit they’re wrong about something small. Not the big stuff. Everyone struggles with that. But the little things like mispronouncing a word or remembering a date wrong. If you can’t just say oh my bad and move on, that tells me you’re more interested in being right than being accurate. Smart people are wrong all the time. They just don’t stay wrong.

Not being able to understand that there is usually a lot of nuance in complicated topics. Believing pseudoscience over actual science is also a big one!

My mother’s current bf says I’m stupid all the time. Says he’s not stupid. He asks me a question, ignores my answers and asks my mother who says the same thing as me. He wants to calculate something, I give a mental answer. He ignores that and types it in a calculator, I was right.
TL;DR: People who ignore others, even after asking them for an answer!

When english is their first language and they can barely speak.

Low intelligence is not the same as poorly educated. Someone can be extremely intelligent but not well educated, therefore their grammar, use of certain phrases may not come across as intelligent. I work with a broad variety of the public on a daily basis. For me, I can tell if somebody legitimately is low intelligence or has some cognitive impairment because it seems like they’re trying very hard to understand something but just can’t. I’ll explain something several times and I’ll walk away knowing they are going to try their best but only a little bit is going to be absorbed. I’ve also noticed low intelligence people seem to be attracted to other low intelligence people and vice versa with people of higher intelligence.

When I say I have ADHD and they instantly begin self diagnosing themselves because they’re always so messy and forgetful. But an ADHD radar works the same way as a gay-radar. I can spot them both from a mile away and I wouldn’t miss one right in front of me.

When they’re right even when they’re wrong. Accepting you were wrong in a debate is a sign of intelligence. Rejecting even the notion shows a lack thereof. You’re not standing up for what you believe in, you’re ignoring any evidence that disproves your original assessment.

A pattern of bad choices, but blaming everything else. Complaining, but adding more to the bad choice pile. Never has an urge to learn. Asks questions about basic things even in topics or around hobbies they are interested in.
