  1. @spandrell – “Hey what’s the cut-off between normal links and bonus links? Never understood how you do it.”

    oh, it’s something like hbd topics=normal links, other interesting stuff=bonus links, but it’s kinda floating. sometimes i put particularly interesting science stuff in normal links, too — like today i threw in the article about agriculture and tooth decay ’cause i thought that was kinda cool/gross. (~_^)

  2. @big nose kate – “Do you have a team of people working for you? Just how fast is your reading speed?!!!”

    heh. (^_^) well, first of all, i (we) have no television machine. which is a good thing ’cause i’d just be glued to it watching all those nature/wildlife documentaries (we just buy the dvd sets instead). so, lots of time to spare to be online. (~_^) also, i will admit to sometimes, occasionally, perhaps, maaaaaybe … only skimming over some of the things i include in the linkfests. (shhhhhhhhhhh! don’t tell anyone!)

    “as gender roles are liberalized, the authors speculate that new studies may show even less divergence between men and women in the United States. The opposite may be the case in cultures that are far more prescriptive of male and female roles, such as Saudi Arabia, Reis and Carothers predict.”

    Such studies were already carried out and what they find out is that the more liberal society, the larger the differences. I mean, authors do not have to speculate, they could just check the literature for the God’s sake.
    E.g. schmitt, realo, volacek 2008 “why can’t a man be more like a woman? sex differences in big five personality traits across 55 cultures”:

    “Overall, higher levels of human development—including long and healthy life,
    equal access to knowledge and education, and economic wealth—were the main nation-level predictors
    of larger sex differences in personality. Changes in men’s personality traits appeared to be the primary
    cause of sex difference variation across cultures. It is proposed that heightened levels of sexual
    dimorphism result from personality traits of men and women being less constrained and more able to
    naturally diverge in developed nations. In less fortunate social and economic conditions, innate personality
    differences between men and women may be attenuated.”
