Some environmental factor — or collection of factors — is causing a drop in the IQ scores of parents and their own children, and older kids and their younger siblings. One leading explanation is that the rise of lower-skill service jobs has made work less intellectually demanding, leaving IQs to atrophy as people flex their brains less.There are also other possibilities, largely untested, such as global warming making food less nutritious or information-age devices sapping our ability to focus.Ultimately, it’d be nice to pin down the precise reason IQ scores are dropping before we’re too stupid to figure it out, especially as these scores really do seem connected to long-term productivity and economic success.And while we might be able to compensate with skills besides intelligence, like determination or passion, in a world where IQ scores continue to fall — and where the drop expands to places like the United States — there’s also a bleaker scenario: a global intelligence crisis that undermines humanity's problem-solving capacity and leaves us ill-equipped...
You have not seen a functional, non-corrupt democracy in any country with an average IQ below 90...IQ is related to criminality... there's a sweet spot for criminality around IQ 85...IQ is related to the stability of marriages... ...
I'd like to see the breakdown on this by race.
some environmental factor is afoot.
information-age devices sapping our ability to focus
There has been at least 60 years of television that would argue your average person doesn't have a hight IQ to begin with. What a load of crock. I do believe Ivy League graduates IQs are dropping though. There are Walmart shoppers more intelligent than those Liberal douche bags.
If you could elevate IQ through mental calculations and short term memory routines, we wouldn't have so many inadequate simpletons around.
It's proven that you can enhance your brain function with mental calculations and single-threaded - i.e. no multi-tasking - focus. Play an intense 2 hour game of chess, do some math on paper, solve crosswords, sudokus whatever. Multi-tasking and loss of attention-span is negative for the IQ. Of course there are many other factors as you mentioned.

Or gain skill at a particular task. But that's not IQ.
All mental exercises aside, there is a couple of environmental factors that have changed from previous centuries. 1)GMO food bred for looks but not nutrition.2)low-fat diets have been promoted as healthful for several decades now, and they include less of essential fatty acids for brain development. Specifically Omega 3 fats have been replaced with Omega 6 fats because they’re less hydrogenated which is supposed to be better for you, but really these fats (canola oil, etc) just increase inflammation and contribute to heart disease. 3)most critically: women aren’t building up their supply of essential fatty acids which they carry on their hips to make them curvy and pleasing to men’s eyes. Instead they are putting on far too much weight (in pursuit of adequate fatty acids), which cause less fertility and more health problems. 4)Then, the women aren’t breastfeeding, or aren’t breastfeeding enough. Breastfed infants are scientifically proven to be smarter than formula ...
After-school activities are more structured than ever (it's sports practice verses "go play in the yard with the other neighborhood kids").
"The results show that large positive and negative trends in cohort IQ operate within as well as across families. This implies that the trends are not due to a changing composition of families, and that there is at most a minor role for explanations involving genes (e.g., immigration and dysgenic fertility) and environmental factors largely fixed within families (e.g., parental education, socialization effects of low-ability parents, and family size). While such factors may be present, their influence is negligiblecompared with other environmental factors"https://conversableeconomist.blogspot.com/2019/01/the-flynn-effect-rising-iq-scores-over.html
Ok so smart women have less offsprings. i.e. dysgenic fertility. I didn't get how this explains a loss of IQ within the same family from parents (mother) to kids.
Check out the link in your post above. The "same family" was based on father to son comparison (that's why I said the methodology was entirely wrong, as most genes relating to IQ/intelligence are located on the X-chromosome). Fathers don't pass X-chromosome to Sons. Sons only get X-chromosome from mothers. The post-modern culture of encouraging women to put in their best biological years for the boss and the taxman is making less smart women available for choosing by fathers, and the sons only get X-chromosomes from mothers.
Interesting! Single Mothers, the #1 Social and now Genetic Disease effecting the nation.
Shitty parenting is to blame. Dude, some our neighbors don’t parent children, they think it’ll stomp their creativity. Too fucking many very shitty liberal minded parents fucking up their own kids.
