      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.

        This is the plot to a fictional movie. Intelligence is a factor of many things, and most of those factors are not genetic.

        Your observation seems close to the opinions of old school eugenicists. “The wrong people are having children”.

          it is not genetic, it is environmental. Children of parents with less intelligence will not be raised to be intelligent. They might be lucky/resilience and try to get the most support outside the house, but it is much harder to accomplish, and often is even met with harassment at home, due to the rest of the family being insecure about their own lack of intelligence. And that is only if they rebel, which is not necessarily true as they will not only lack easy access to basic knowledge about the world/science, but will also not be introduced to the importance of learning about it from their closest figures of authority. Escaping that cycle it is even harder if the family is facing economic hardship, which is true for most modern families in general. It really isn’t that hard to figure that out, the kneejerk reaction that the statement always gets is annoying.

          The intro to Idiocracy doesn’t actually mention genetics.

          Smart people value intelligence and people who value intelligence will raise their children as such.

          Parents who don’t value intelligence don’t raise their kids with intelligence in mind.

          Public schools aren’t actually about education. They’re about job training and obedience, so they wont fill the gaps the parents are leaving.

      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.”

      idiocracy intro?

      (IE the theory it pushed was in short, smart people do family planning, try to wait for everything to be perfect… and forget to get around to having kids).

      Meanwhile on the less intelligent spectrum. Shit I’m pregnant again!!!.. Oh and I got the girl in the trailer next door pregnant.

      Or for a real world example… look at Lauren Boebert, the 35 year old grandmother in congress.

        Yes absolutely (and i was afraid to say it out loud).
        But now, we have also to explain why it did not so much apply in the past millennias … or tens of past millenias. (again, i am afraid to say it … don’t want a shitstorm)

          The massive lowering of the bar of “good enough to stay alive”. Life expectancy was consistantly in the 30s up until the 1870s. Simply having kids was life threatening… doing so while malnourished even more so.

          Natural selection favors traits that increase the odds of having offspring, as well as those that avoid death before having offspring. Avoiding death is a lot easier than it used to be.

            For what it’s worth the average life expectancy was 30-something. That didn’t mean that everyone, or even the mostly everyone, just dropped dead at 30.

            It did, however, involve an awful lot of people dying in childhood. Often due to diseases that these days we’ve almost stamped out, but now antivax morons are working hard on bringing back!

              Yeah, I at least assumed that was understood with just “expectancy”, obviously people live longer than expectations, and some die unexpectedly young. Key point is if you were given a mission where you must become a baby, and carry on life until you have 6 kids reach the age of 18. But you could chose what time to be born in (but not pick location, class or race), the lowest difficulty mode of that game would almost certainly be after 1950s… and prior to the 1800s would be viewed as very hard mode.

          Part of the answer is that mortality rates were far higher 150 years ago. A couple might have 5 children but only 2 survive to adulthood.

        Lead was a much bigger problem in the 1970 when it was in road vehicles fuels. But now its only use in some small plane fuels. There is also much less use of lead paint and lead in water pipe systems.
        N.B. : Study in that article is about decline from 2010 until today in 15-year-olds.

          I remember still having to ask for unleaded gas, and that was in the '90s. Plenty of houses still have lead paint and lead pipes. Sure it was more of a problem in the 70s, but it didn’t go away after that.

            Lead paint is encapsulated and not going to enter your body. Which houses have lead pipes? Even the houses I’ve lived in over 100 years old have all had complete copper plumbing.

        i agree that some aggregate of all of these, and to various degrees, and differently for different people, would apply. Also, i did not say more so to let the discussion open.

        Now, about text formatting in here :

        .
        i wanted one line for each items
        yet I didn’t want it in 2 lines/items

        see examples here :


        line # 1(no spaces + one line feed) line # 2


        line # 1(no spaces + 2 line feed)

        line # 2


        So, the only way to get the formatting i wanted is to have two spaces at the end of each lines followed by one line feed.

          For future reference, you can add a \ at the end of your sentence.

          So you can accomplish this.
          And then this.
          But don’t put one on the last listed sentence, or it will look like this.\

          I meant between your last letter and the punctuation marks. Not the spacing of the lines. Use an asterisk for lists if that’s your goal?

            instead of “goal?”

        Yes it is possible … but this factor is difficult to measure, as it may go both ways, depending on motivation to learn new things and if that AI is a good teacher or … is giving ready-made (and bad) answers without helping to go further.
