    Louis Thurstone pioneered the concept of multiple intelligences, in opposition to the idea of Spearman's g-factor. After conducting his tests, he used a statistical fallacy called "restriction of range" to hide correlations between the abilities he was studying. Basically, he held IQ constant by only comparing, say, people who scored 100 IQ overall, and found that overall IQ score had no predictive power (which is true by definition).

    Later scientists found the expected g-factor in his data using factor analysis on the full dataset. Whether this was incompetence on his part or disingenuousness is a matter of speculation, but I believe it was almost certainly disingenuous.

    Might be "S-back" as well, although not on the level of Kim Jong Il or Pavel Grachev. It looks like he may have had a fairly wide head with the widest point on the cranium just above the ears.

    I agree with you that he was probably being intellectually dishonest in the promotion of his theory of multiple intelligences.

    Nasty looking dude. I would call that avgtemp. Explains the willingness to fudge data.

    Just for the maintenance of rigor, Koanic doesn't want unconfirmed traits listed in title names (rather, add them as initialed tags). That said, if you've signed on to crinklesock that may well be the crucial impetus for it to be considered consensus.

    Hehe. I make myself laugh sometimes.

    I'm almost certain that crinklesock refers to something real, but I'm not confident in my ability to read it at this point.
