It's not. Everytime there's a new form of media or communication there's an uptick in "bad actors". Think yellow journalism or any of the moral panics around TV programming. Even back when the printing press was invented there was an uptick in troll behavior. One of the Green brothers posited that martin Luther was really just a pamphlet troll.
With social media and the Internet, stupid just got louder. I don't think people got stupid.
IQ tests are administration-sensitive and have changed dramatically since the beginning of such a Flynn effect study. The population makeup of many countries has changed in recent years to include many immigrants for whom the study would make exceedingly little sense to include. IQ tests do not cover and do not claim to cover a comprehensive view of human intelligence, famously lacking verbal and social components entirely. It is possible past IQ tests were simply overtuned and we’re now seeing the natural correction.
Amplifying stupid can be very deadly, though. In some sense, the printing press caused the 30-year war, and radio brought us World War II. Eventually, society will adapt. I just wish we could find a way to adapt faster than the bad actors do.
Just to be clear, that "speed-up" is not a good thing: Those 100 years were a lot less deadly in total. The World Wars were even shorter and much deadlier still. A possible next full-blown conflict between major powers will only last hours -- and end civilization.
I feel like declining human intelligence is a result of advancing machine intelligence. Computers are a force multiplier and societal pressure towards building intelligence is reduced.
So the AGI/ASI problem might solve itself: we slowly become incapable of iterating on the problem while existing AI is not nearly advanced enough to pick up the slack.
It’s quite beautiful. Once a civilization tries to build machine intelligence it slowly degrades its own capacity during the process thus eventually losing all hope of ever achieving their goal - assuming they still understand their goal at that point. Maybe it’s an algorithm in the Universe to keep us from being naughty.
The human brain optimizes for efficiency, if that extra intelligence doesn't confer survival benefits it'll be lost. I can't imagine that intelligence doesn't confer survival and reproductive benefits though, it's more likely that the gradient of survival and reproduction between the most intelligent and least has shrunk. In a sense civilization is coddling the weak, and humanity is getting weaker for it.
Yes, the strongest man who ever lived is alive today. The best player of every sport is alive today . It absolutely supports the theory support the theory that the smartest person ever is alive today, etc. etc..
Maybe on average, but I think it’s probably correlated to inequality. The kid of two Oxford professors will probably be smarter than a kid that grew up in poverty. The school system is aimed at mitigating these differences, but if on average everyone gets less intelligent maybe the school system is working poorly.
