I wonder if you could analyze internet discussions for an effect.

      Heavy metal exposure

      Sugar

      The proliferation of food additives being used that are known to dramatically lower IQ

      The gelding of our education system by morons who favor religious dogma over scientific fact

      Criminally underfunded schools thanks to political leaders who see investing in future generations as budget waste

      Failure to teach children critical thinking skills before exposing them to technology that makes it simpler for them

      Being constantly bombarded and overstimulated every waking moment by media

      Being chronically overworked and underrested

      Climate change

      Take your pick. The answer is “probably, yes.”

      Short form content like those found on reddit and here on Lemmy have retrained my brain, I’m sure of it. I’m actively trying to fight it, by forcing myself to read full articles, scroll more slowly and try to engage more fully rather than just endlessly scrolling for the next dopamine hit.

      It’s easy to justify this behavior because “I’m just getting my news and staying informed” and while partially true it comes at the cost of the medium it’s provided by. Screen “reading” has definitely changed our brains for the worse and most people have no clue its even happened.

        So far I’m liking lemmy more because there is a lot less per post. I find I’m enjoying each thread more fully. It’s like I’m not endless scrolling because I can’t. I’ve actually read more articles in the day since I’ve joined than in my last 3 months on reddit.

      In my personal observations less intelligent people tend to have more children.
      Therefore population IQ drifts towards bottom.

      I suspect that’s because they do not fully understand all their future struggles and fates of their children in the world, fucked up by climate crisis and resource scarcity.

    So, I’ve seen a lot of people who were extremely sharp as PhD students become blunted as soon as 9–5 starts.

    A lot of decline among adults can likely be traced back to increased cognitive load during working hours, which chips away at intelligence over time as folks burn out.

    With kids it’s harder to place, maybe it’s walking the tightrope that is modern social interactions?

    Bored people can now tune into (source of entertainment) instead of learning.

    I don’t think the capacity for intelligence has dropped significantly, rather we as a society dedicate our time differently.

      Bingo. We have a winner.

      Lack of mental lifting. Critical thinking becomes too hard. Why innovate? The country has become fat, dumb and happy.

    is anyone here talking about the systematic dismantling of public education and starving of teachers and children in terms of learning resources and actual food

    also i again have to complain about Idiocracy, the comedy film that suggests intelligent rich people will solve our problems and stupid poor people will doom society, where in reality you have incredibly wealthy and also incurious, unintelligent ghouls hoarding generational wealth, making it a top priority to have tons of children in order to make their ‘superior’ genes take over.

      The fact that teachers need to beg for pencils is disgraceful. Teachers should get paid more and not have to pay for their supplies.

    I can believe it. Physical inactivity, less creative play for children, distraction all the time.

    Mind you, in some ways I don’t buy it - the two of my kids who were very academically motivated both learned much more in school than I did (I went during a conservative time when the schools were doing “back to basics” which didn’t help, but simple research before the Internet was so difficult that I didn’t have access to as much as they did, it took more effort to learn less) and those two are whip-smart. So I think the potential to be smart is higher now. Also maybe we have included more people in the measurements now that it’s easier to get the data.

    But physical inactivity does harm brain health, plastic probably does, the dumbing down again in the schools here (is this some 40-50 year cycle?) certainly does. I do, like @drascus@sh.itjust.works work at maintaining my thinking by trying to learn new things, not just get good at what I am good at already; and do a lot to maintain physical health, meditate, and try to guard my sleep as much as possible within the context of a normal life.

    Tech companies hire psychologists to behavior modify us to be engagement zombies. That alone must have done a number on intelligence.

      One, we’ve off loaded much of our critical thinking and researching skills to Google et al. This will only get worse as we develop stronger AI assistants that perform a majority of the “thinking” tasks. Technology frees the mind in some ways and reduces the need for certain functions. I read an article probably 10 years ago about how Japanese struggle to write because cell phones and computers have taken over much of that skill.

        To be fair, the idea that writing has to be this perfect penmanship that will be readable in 1000 years is silly. Write things down in a good enough style for the task at hand.

    Summary The article describes a decline in human intelligence, particularly among young people. The decline is attributed to reducedk reading habits and the negative impact of excessive screen time on cognitive abilities.

    The FT source seems to be behind a paywall, and this article seems to be jumping between a bunch of possibly unrelated issues (focusing on young adult cognitive decline but looking at whole population reading rates and numeracy ability).

    Every generation will be more intelligent than the last, our exponentially complicating world requires it.
