I was thinking about this. I went to university, and I worked in tech for decades. I met many assholes but I didn’t meet anyone that would fit on the left half of the bell curve (less than 100 iq).
Since I’ve been living in that bubble my entire life, I’m curious of your stories. Have you met someone who was actually quite dumb (not just having opinions you don’t agree with) and do you have an example situation you remember you can share?
Hopefully this becomes more funny than hateful since intelligence is not the value of a person, but it can be funny to read the stories.
When I was in high school, I volunteered for a couple of days in a special ed class, which, I guess by definition, contained people with sub-100 IQ (sub-70, even). I guess that fits your specifications. One thing I remember observing was that the girls were more capable of stringing together coherent sentences than the boys.
Also, a couple of years ago, I worked as a school bus driver for 3 months while looking for a tech job. There seemed to be much more variance in intelligence among my colleagues than I was used to: some seemed to be just as smart as most of the ones in my previous tech jobs, but others, while they were generally nice enough, seemed to fail to grasp basic concepts or retain information very well during the training.
