> There is not really that much deviation in intelligence among most adults.
I cannot think that you have a lot of experience with all social classes if you think this. I have extremely disordered family members with mental disabilities and I regularly come into contact with their friends and service-industry coworkers. A lot of adults struggle with memory, comprehension, logic, speed, and reasoning, which I would call "large deviations in intelligence".
It's one of those luxury and insular beliefs that could only possibly arise from a sheltered existence. Just for example, anyone who both went to a decent university and grew up in a not-decent public school could not possibly have this opinion.

Yeah I really can't take this share by OP seriously and can't help but wonder if the post is on some level clickbait. I keep my circle pretty diverse and have had a few jobs where I interact with people outside of my norm... I've met some people that truly lack in areas that are clearly identifiers of "intelligence": critical thinking, problem solving, memory, communication and social skills... Intelligence can be defined as a lot and yet I still have met some people who are clearly an idiot - and I don't really consider myself to be super intelligent either. After getting into the workforce, I would maybe describe myself as above average but that's only because of the people I've met bringing down the average to below my level.
