A defining trend in human intelligence tests that saw people steadily obtaining higher IQ scores through the 20th century has abruptly ended, a new study shows.
The Flynn effect – named after the work of Kiwi intelligence researcher James Flynn – observed rapid rises in intelligence quotient at a rate of about 3 IQ points per decade in the 20th century, but new research suggests these heady boom days are long gone.
…
The researchers sourced their data from the IQ test scores of 18- to 19-year-old Norwegian men who took the tests as part of their national, compulsory military service.
Between the years 1970 to 2009, three decades of these young men (born between 1962 to 1991) were conscripted, resulting in over 730,000 IQ test results.
What the results show is that a turning point for the Flynn effect occurred for the post-1975 birth cohorts, equivalent to 7 fewer IQ score points per generation.
…
In the new study, the researchers observed IQ drops occurring within actual families, between brothers and sons – meaning the effect likely isn't due to shifting demographic factors as some have suggested, such as the dysgenic accumulation of disadvantageous genes across areas of society.
Instead, it suggests changes in lifestyle could be what's behind these lower IQs, perhaps due to the way children are educated, the way they're brought up, and the things they spend time doing more and less (the types of play they engage in, whether they read books, and so on).
Another possibility is that IQ tests haven't adapted to accurately quantify an estimate of modern people's intelligence – favouring forms of formally taught reasoning that may be less emphasised in contemporary education and young people's lifestyles.

Harvard does do real studies and not just bull crap.
You can blame the way IQ’s are measured.
The overall populace in the western world has become more educated as a trend since the dark ages, and that would be measurable on tests and are oriented to measure for it, but people in modern civilization are NOT becoming more intelligent in my opinion. Civilization is exchanging practical problem solving and critical thinking for socialized behavior and rote specialization of knowledge and skills.
Pot
Don’d worry our SJW’s will soon have the IQ test “adjusted” for “diversity”.
White guys will instantly become dumber.......
LOL!
No worries....smoking more dope will ensure nobody cares about IQ....
Your calculator analogy also applies to spelling.
I used to be a great speller. Over time, I’ve leaned on autocorrect so much that sometimes it can’t even make a suggestion.
Factoring in “Norwegians” named Mohammed is going to lower the score.
...But the median IQ is still 100, right?
Do i have to come over there and slap you silly?
What was the percentage of immigrants taking the tests then and now?
Al Gore warned us about that! He told us that inhaling increased amount of CO2 makes you dumb.Never mind that atmospheric CO2 is less than 1% of the atmosphere, and the concentration of CO2 in the lungs after inhalation must be at least an order of magnitude greater than that, considering that you can never exhale all of the gas in your lungs (if you do, you have what doctors call a “collapsed lung” - and that ain’t good).
I did not allow my kids to have or to use a calculator until the algebra teacher said to get one in ninth G
No video games, one tv in the house. One computer.
I guess i shouldn’t wonder at the 3.6 + gpa s but it’s scary that kids feel good about not thinking
I used to tell my ninth grade english class, no, your computer can’t do all this for you i knew guys (father) who worked on the ground floor inventing and putting out personal computers. Tgey went to school when they were 14. They had to learn shakespeare, american lit, so get back to work
The IQ drop begins with those born in the mid 70s.
The massive technology revolution begins in their teenage years, rapidly spreads to play, work and education and with it performs many skills we use to have to employ from our brains alone. That aspect - do it by technology not by our brains, as even escalated more each decade.
But nothing in the article suggests the researchers are even considering it.

BK Eakmann is why i home schooled as long as practical and chose high school very carefully
That's equality of "outcome", not "opportunity". Not quibbling; there is a huge distinction, though.
Simple. I have no verification about your IQ and if I call you a liar, I am right 99.9998467663% of the time. Pretty good odds, I’d say. And, on the non objective side of things, I know from experience with persons beyond gifted, that it is almost an article of faith that they do not quote a number like you have. So, I put you in the crackpot braggart bucket for that fact alone and then, of course there are the odds.
Since the early 20th century, raw scores on IQ tests have increased in most parts of the world.[62][63][64] When a new version of an IQ test is normed, the standard scoring is set so performance at the population median results in a score of IQ 100. The phenomenon of rising raw score performance means if test-takers are scored by a constant standard scoring rule, IQ test scores have been rising at an average rate of around three IQ points per decade. This phenomenon was named the Flynn effect in the book The Bell Curve after James R. Flynn, the author who did the most to bring this phenomenon to the attention of psychologists.[65][66]
