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."

Heavy metal exposure

🤘😠🤘

[–] dutchkimble@lemy.lol 0 points 5 months ago (1 children)

Everything you said makes sense...except heavy metal exposure. Unless you mean lead or something...

[–] Schmoo@slrpnk.net 1 points 5 months ago

I know the phrase is ambiguous but from context they clearly meant actual metal.

All of these and more. Did you know our carbon emissions are changing the ratio of oxygen in the atmosphere as a whole? Guess which species is known to get dumber when oxygen deprived. Don't worry about the warming ocean's increasing acidity, it just makes the ocean a more difficult habitat for the phytoplankton that make 65%of the oxygen in the atmosphere.

I'm sure our normalcy bias will protect us or maybe the invisible space monkey will save his favorite primates if we can commit a few more hate crimes in his name.

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.

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".

[–] AA5B@lemmy.world 1 points 5 months ago* (last edited 5 months ago)

The problem with eugenics is proposed solutions, or criteria based of prejudice.

I claim it’s both fine and correct to state that the wrong people have too many children. You’re the wrong people if you have more children than you can adequately care for, to raise sufficiently for them to have a successful life. You’re the wrong people if you have children you’re not prepared for or otherwise can’t commit to raising or don’t have the ability to raise.

It’s wrong, eugenics, when

  • it’s prejudicial such as based on race, culture, religion
  • you’re judging another person’s worth, their rights on that worth, or their opportunities on their worth
  • you take it to an extreme, such as only the wealthy should have children.
  • you prescribe a solution that imposes your will on other people, or worse, legal or medical intervention


Better answers include

  • better education helps people make better choices
  • better medical care helps people know their choice will succeed
  • better safety nets help each child succeed even when their parents made a poor choice or had unexpected life events
  • better childcare options help give the parents a chance to succeed with trying to earn a living while raising a child

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.

[–] A_A@lemmy.world 0 points 5 months ago (1 children)

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)

[–] TheFogan@programming.dev -1 points 5 months ago

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.
