Rising stupidity rates since 1975

Bernt Bratsberg and Ole Rogeberg at Norway's Ragnar Frisch Center for Economic Research have gathered “scientific proof” that we're all getting dumber. In their paper it’s reported that IQ scores have been dropping since 1975.

The study analysed 730,000 IQ test results from young men entering Norway's compulsory military service from 1970 to 2009. IQ scores declined by an average of seven points per generation, a reversal of the so-called “Flynn effect”, where IQ was rising in the 20th century until 1975.

Bratsberg and Rogeberg discounted as significant causes: parental education, family size, increased immigration, and genetics.
They couldn´t figure out what the ultimate cause is.

According to the following, only in a small amount of countries, besides the Kingdom of Norway, IQ has declined…

In the Kingdom of Denmark the IQ of male conscripts declined about 1.5 points from 1998 to 2004.
They thought that this has to do with the simultaneous decline in students entering 3-year advanced-level school programs for 16–18-year-olds and/or the rising proportion of immigrants (and their children).

In the United Kingdom, the IQ score of an average 14-year-old from 1980 to 2008 dropped with more than 2. However, the IQ for children aged between 5 and 10 saw an increase over these decades.
Flynn argues that the abnormal drop in British IQ from 10 to 14 is because the youth culture has dumbed down, including an orientation towards computer games instead of reading and talking.

It has also been argued that a higher fertility is associated with lower IQs.

In British colony Australia, the IQ of 6–12 year olds has shown no increase from 1975 to 2003: https://en.m.wikipedia.org/wiki/Flynn_effect


In 1968, George Land researched the creativity of 1,600 children starting in age from three-to-five years. He re-tested the same children at 10 years and again at 15 years of age. The results were astounding.
Test results 5 year olds - 98%
Test results 10 year olds - 30%
Test results 15 year olds - 12%

The same test was given to 280,000 adults, who were only 2% “creative”.
A good explanation could be, that our educational system was designed to train us to be good workers that follow instructions: https://www.creativityatwork.com/2012/0 ... be-taught/


Several studies have shown that humans become (even) more stupid from watching TV.
For example one study followed 3,247 people over a 25-year period, whose average age at the beginning of the study was 25 years old.
The researchers then divided the people into four groups, depending upon the number of hours they watched television per day. Approximately 11% watched more than three hours of TV per day and were put in the high television-viewing group (353 of the entire Group). There were 528 low television watchers (16%).

At the end of the 25 years, those in the high television-watching group scored significantly lower on 2 of the 3 intelligence tests (56-64%): https://www.realnatural.org/excessive-t ... mpairment/
