I've been randomly looking up stuff about the movie Idiocracy. After watching a video on youtube claiming that the world of Idiocracy is actually a Utopia (because the world seems to not have the problems that real-world incompetence causes), that got me thinking: what would a world where everyone had below average intelligence actually look like?
However, I've been having a hard time doing research for this topic. I've tried to look up what people with an iq of 80 are actually like, only to find widely contradicting claims as to their capabilities. I found one who claimed he couldn't even drive a car because he was so bad at multi-tasking. Another claimed that they can function in society perfectly fine, but with the caveat that they couldn't take any jobs that require a degree. Another claimed that their 80 iq was enough to get them classified as 'special' (even though I thought you had to have an IQ of 70 or lower for that, but what do I know?)
The problem with such a conworld, regardless of whether we're talking about a world with below or above average intelligence, is that we have no real-world examples to draw on. Yes, there's people with non-average IQ scores, but they've lived their whole lives in a society where they're the minority (obviously). This means that, honestly, real-world people with non-average IQs simply could never give us an idea of what a world would be like if they were the norm. For instance, one common thing I've come across is that people with below-average IQs tend to suffer from an inferiority complex. Questionable reliability aside, if this was true, it certainly wouldn't be true in a world where they were the norm. Also, its not really possible for a person to realistically write a character that's smarter than they are. And as for below-average intelligence, I just don't know where I could look to get realistic information. The movie itself was clearly not based on research (and really, the movie was intended to be a satire of consumerism anyway). All I can really say for a fact is that people with below-average IQ don't talk in the stereotypical way you often seen protrayed in media. And this is something I've long known from my studies in linguistics; people who seriously are 'special' don't make grammatical errors or pronunciation mistakes (unless they have some kind of problem with motor skills), but they do demonstrate a (relatively) limited vocabulary.
So yeah, how could I find reliable research on this, and could anyone reveal to me their own research (preferably with citations) into this matter?
