Being real, IQ scores are falling
This is something many people that like me noticed that came out
of school from the 80's into the 90's. Education now seems to be lower
than it was for me back then. For my time from High school going into
college I was upset when I found out Hoover wore a dress and I knew
nothing about the Coolidge effect. My High school never told me this
now I have to catch up I'M NOT READY FOR COLLEGE!!!
But I adapted and pushed more in what I was missing so I could catch up.
My education was all over the place. I seen it as disabling yourself by
limiting your education to a box. Life is not boxed so accordingly
I learned all I could. A point of deeper learning, multiple intelligence's
from it all making me more of a INFJ as consequence or my dad being a
oil engineer and others in my family I had a background so I was able to
just jump into college. But I felt that High School in the 80's was not
covering it enough for me back then. But also I was fresh so I didn't know
what I was doing and so is why you go to college to know
what you are doing. Don't hold yourself back learn all you can!
I noticed the change in the kids the riff when I was in my final years in college.
I was taking a drug class but the freshmen students seemed to be obsessed
with things un-relating, un focused etc! I noticed it.
It gave me a red flag back then!
IQ's are getting lower, and if you are like me you noticed it.
It wasn't just you, this is real! There are many real reasons for this.
Many teachers suspected why it is but as it is many are right.
~~~~~IQ scores are falling and have been for decades, new study finds
IQ scores have been steadily falling for the past few decades, and environmental factors are to blame, a new study says.
The research suggests that genes aren't what's driving the decline in IQ scores, according to the study, published Monday.
Norwegian researchers analyzed the IQ scores of Norwegian men born between 1962 and 1991 and found that scores increased by almost 3 percentage points each decade for those born between 1962 to 1975 -- but then saw a steady decline among those born after 1975.
Similar studies in Denmark, Britain, France, the Netherlands, Finland and Estonia have demonstrated a similar downward trend in IQ scores, said Ole Rogeberg, a senior research fellow at the Ragnar Frisch Center for Economic Research in Norway and co-author of the new study.
"The causes in IQ increases over time and now the decline is due to environmental factors," said Rogeburg, who believes the change is not due to genetics.
"It's not that dumb people are having more kids than smart people, to put it crudely. It's something to do with the environment, because we're seeing the same differences within families," he said.
These environmental factors could include changes in the education system and media environment, nutrition, reading less and being online more, Rogeberg said.
The earlier rise in IQ scores follows the "Flynn effect," a term for the long-term increase in intelligence levels that occurred during the 21st century, arguably the result of better access to education, according to Stuart Ritchie, a postdoctoral fellow in cognitive ageing at the University of Edinburgh whose research explores IQ scores and intelligence and who was not involved in the new study.
Researchers have long preferred to use genes to explain variations in intelligence over environmental factors. However, the new study turns this thinking on its head.
Intelligence is heritable, and for a long time, researchers assumed that people with high IQ scores would have kids who also scored above average. Moreover, it was thought that people with lower scores would have more kids than people with high IQ scores, which would contribute to a decline in IQ scores over time and a "dumbing down" of the general population, according to Rogeberg.
Anyone who has seen the film "Idiocracy" might already be familiar with these ideas. In the scientific community, the idea of unintelligent parents having more kids and dumbing-down the population is known as the dysgenic fertility theory, according to Ritchie.
The study looked at the IQ scores of brothers who were born in different years. Researchers found that, instead of being similar as suggested by a genetic explanation, IQ scores often differed significantly between the siblings.
"The main exciting finding isn't that there was a decline in IQ," Ritchie said. "The interesting thing about this paper is that they were able to show a difference in IQ scores within the same families."
The study not only showed IQ variance between children the same parents, but because the authors had the IQ scores of various parents, it demonstrated that parents with higher IQs tended to have more kids, ruling out the dysgenic fertility theory as a driver of falling IQ scores and highlighting the role of environmental factors instead.
What specific environmental factors cause changes in intelligence remains relatively unexplored.
Access to education is currently the most conclusive factor explaining disparities in intelligence, according to Ritchie. In a separate study that has not been released, he and his colleagues looked at existing research in an effort to demonstrate that staying in school longer directly equates to higher IQ scores.
But more research is needed to better understand other environmental factors thought to be linked to intelligence. Robin Morris, a professor of psychology at Kings College in London who was not involved in Ritchie's research, suggests that traditional measures of intelligence, such as the IQ test, might be outmoded in today's fast-paced world of constant technological change.
"In my view, we need to recognize that as time changes and people are exposed to different intellectual experiences, such as changes in the use of technology, for example social media, the way intelligence is expressed also changes. Educational methods need to adapt to such changes," Morris said.
