    UCLA Team Maps How Genes Affect
    Brain Structure, Intelligence

    UCLA brain mapping researchers have created the first images to show how an individual's genes influence their brain structure and intelligence.

    Published in Nature Neuroscience, very good..

    Very interesting, I'd rather have had them research twins which were brought up in different environments, but I guess those are hard to find..

    Btw, welcome to the Forums, Carlos Hernandez!

    Thanks for the welcome! Here are some twin studies that you were looking for: http://www.lrainc.com/swtaboo/taboos/tjbouc01.html

    Subject: The Smarter the People, the Richer the Nation

    Charles Murray is certainly correct that "The best source is Art Jensen's
    The g Factor (1998)" for his statement that despite thousands of attempts to
    show there is much more at work in human intelligence than the g, or general
    factor, it has simply not been demonstrated. Psychometricians who work in
    industry, the militray, and in education have done their utmost to find what
    they call "incremental validity" for predicting success, even to the point
    of loading in personality factors like conscientiousness to see if they can
    get better predictions for employers, etc. So far the evidence is not good
    that much more than g is operating. (Spatial ability may show increements
    for fighter pilots; conscientiousness for check-out counter employees).

    Having just come back from three days of talks on intelligence at the
    International Society for Intelligence Research at Newport Beach, I can say
    that this picture remains true. Moreover general intelligence is being
    mapped more and more as being in the forebrain and depends on the speed and
    efficiency of processing information. The g factor is even extractable from
    reaction time measures that everyone can do in less than one second. There
    are hopes that IQ research may be put on a ratio scale of measurement with
    chronometric apparatus in which there is an absolute zero. Chronometrics
    give very lawful results, correalting highly with standard IQ tests and
    brain scans and show steady increases in children all the way up to 24, and
    then steady decrements until death, just like do g measured IQ and as does
    the size of the brain.

    This is true cumulative science. Of all the conferences in social sciences
    that I go to it is the ONLY conference that seems to show the cumulative
    effects of knowledge and not trendy in-cliques that seem to characterize so
    much other work. (Admittedly not way beyond Spearman's 1904 model of general
    intelligence nor Karl Pearson's first heritability estimate for IQ of 50% or
    Paul Broca's 19th century finding that forebrain is responsible for the
    highest forms of abstract reasoning.) But at least it is correalted with
    incremental truth and that's a huge relief for some of us who sometimes
    think others don't even believe there is such a thing.

    Carlos, I didn't find the essay you quoted here at Rushton's homepage which you linked to. The partial URL you gave for the essay was no help either. Can you give me the correct URL? Thanks.

    The Rushton quote was posted by Rushton at I think the Evolutionary Psychology mailing list at http://groups.yahoo.com/group/evolutionary-psychology/ Yahoo groups is down right now, you'll have to check back later. And what other links are you referring to? Here is all the links I have on rushton's works:

    Okey, I found the link you wanted: http://groups.yahoo.com/group/evolutionary-psychology/message/28360 Professor Rushton is an active participant on that mailing list.

    Thanks Carlos. I bookmarked that whole message board, which I didn't know about. Seems valuable.
