    Lowering of human intelligence article

    Can't help but think this is funny-in particular the theory that it started right around the introduction of agriculture

    I can't get the link to work. Do I have to click on it or something?

    It's a theoretical/speculative article, not science. The article can basically be summarised as saying that because there's less selective pressure on populations now, by definition we must be getting dumber (since presumably intelligence would be selected for).

    In terms of actual data, the only period we have detailed information for is post 1940, and the Flynn effect (which is completely environmental, not genetic) completely swamps the theoretical intelligence degradation due to relaxed selection pressure.
    Disclaimer: I eat 'meat and vegetables' ala Primal, although I don't agree with the carb curve. I like Perfect Health Diet and WAPF Lactofermentation a lot.

    You write good!
    "I think the basic anti-aging diet is also the best diet for prevention and treatment of diabetes, scleroderma, and the various "connective tissue diseases." This would emphasize high protein, low unsaturated fats, low iron, and high antioxidant consumption, with a moderate or low starch consumption.

    In practice, this means that a major part of the diet should be milk, cheese, eggs, shellfish, fruits and coconut oil, with vitamin E and salt as the safest supplements."

    You are right. It seems his answer alone disproves the article. hehe

    I'm not sure if it is entirely based on genetic selection, either. There's a fair amount of environmental factors that could be relevant- chemical differences could cause a slowdown of synapse transmission. I have no idea if that's true or not, or even possible, but there are a lot of things to rule out before you can say it is definitely genetic.

    Also, children have become more children-ified. Parents don't let them do things they are capable of, and educators aren't any better. For example:
    think:lab: 8th Grade Examination from late 1800's
    I'd do terribly at this test, and I've seen similar ones that include a fair amount of Greek and Latin, which this one doesn't include at all.

    There's a lot of interesting stories from John Taylor Gatto's book, "An Underground History of American Education" that involve young people of 13-15 doing things like establishing their own homesteads, or becoming captain of a ship, with a full crew. My wife was just talking with a classmate who is about to graduate and hasn't found a job. She fully expects her parents to support her, because they supported her sister. My wife and her classmate are graduating from law school! Everyone is at least 25 years old! Society now has this extended adolescence that is getting longer and longer, where young people are not expected to make any kind of positive contribution to themselves, their families, or society.

    I'm ranting, but I'll stop now.

    This and PUFAs, fluoridation, aspartame, HFCS, vaccines, compulsory schooling, the media. etc.
