IQ Scores Are Falling in "Worrying" Reversal of 20th Century Intelligence Boom
sciencealert.com ^ | 13 JUN 2018 | PETER DOCKRILL

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.

Okay. I have been invited to join Mensa more than once, I always decline. If you ever meet a Mensa member, the first thing you’ll learn is that he or she is a Mensa member. So I actually try to avoid being a ‘crackpot braggart’. I simply said something that I thought was in context to this thread.

My favorite low IQ question I heard from a worker. If we make buildings too tall will they hit the moon?

The answer to that question is: Yes. (NOTE: "Too" = approx. 238,000 miles high, though only in the case of building sites roughly within the Tropics.)

Regards,

“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.”

Whenever data doesn’t align to the existing standard, the standard is at fault. It’s the essence of liberal belief.

What I gather is this: Focusing on feelings and emotions, doing what makes you “happy”, and allowing everyone to “win”; actually makes people dumb.
I believe those of us with common sense knew this already.

Just to be sure, my comment was odds related, not intended to be personalized. The crackpot bucket thing was sarcasm, sort of.

I raised a son with an IQ of more than 20 points higher than my own and know that being smart is not always an easy path. Good luck.

We’re cool, thanks. You’ve been here about as long as I have, so I respect your opinion. Yeah, I was always in the ‘gifted’ class in school. Best with your son.

Intelligent Americans, millions of them, have murdered their own offspring in abortion. Millions of unintelligent people are having kids out of wedlock. Given 30 or 40 years of that, an overall drop in the IQ of American society is no surprise at all.

The other day the “Pluggers” cartoon was a plugger liking to get the kind of astrophysics question he can handle—his grandson asking if birds were in danger of hitting the moon.

A liberal recently told me that if Trump is impeached, Hillary automatically becomes president because she got the second most electoral votes.

A real constitutional scholar that one.

“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.”

You guys are just now figuring this out? Well, I guess that makes sense.

This is based on a survey taken in Norway. Ethnicity isn’t really a factor. Lifestyle probably is.
