    IQ scores are falling

    Have been for decades apparently.

    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 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.

    Well, if this proves true, I guess I'll have to toss out my DVD of Idiocracy.

    My mom before she passed years ago predicted cell phones would "rot our brains and make us all dumber than a bag of rocks." Maybe she was right.

    Automation is the root cause. Common sense, the basis for IQ, is not developed by a mind that is not challenged to think.

    They do say that in regards to seniors, keep your mind active and alert. I do think it matters even for young people. Kids get intellectually lazy if they lay around all summer.

    And with no mental activity going on that requires logical and rational thought the mind does not develop the neural pathways for more critical thinking.

    So in a sense, reality tv has ruined the human race?

    It sure as hell hasn't helped! Hour after hour blathering NOTHING and tears, often at annoying decibel level. Has ANYONE ever learned anything from a reality show?

    Calvin, on the first day of summer vacation, is in bliss, and says to Hobbes, "I can already feel my brain turning to mush!!"
