  2. Well, I think that we can safely discredit that one: http://en.wikipedia.org/wiki/Flynn_effect

    Socialism and the Welfare State are certainly not doing it any favours, though.

    Human brains have been shrinking since the Stone Age...
     
  4. That's true, but there is little reason to believe that the Flynn Effect has not been in action since then, and to a much higher degree.

    Anyway, as far as I've understood it, brain area (that is, if "unfolded") is more important than volume.

    Except the Flynn Effect claims intelligence has been increasing at the rate of roughly 3 IQ points/decade or 30 points/century. So if it’s been continuous since prior to the start of the Stone Age, and the Stone Age ended between 4k and 8k years ago; then around the start of the Stone Age we would have had around 1,200 to 2,400 fewer IQ points than we do today? :eek:
     
  6. Over greater stretches of time it is obviously not linear :rofl:

    That’s true. You did say “there is little reason to believe that the Flynn Effect has not been in action since then, and to a much higher degree.” ;)

    Probably. Some mix between genetics and epigenetics (‘dysepigenetics’?)

    And while we’re on the topic of dysgenics…
