Is there any indication of increased intellegence over time within the Human species?

RAZD, I just came across your post on this Vanderbilt study. Fascinating stuff.I had previously come across studies that suggested greater creativity in relatives of schizophrenics (as opposed to the cliche of the mad artiste).There is a broad streak of schizophrenia/bipolar disorder in my family, as well as one of musical, literary, and mechanical/engineering creativity in those not fully afflicted.Here is a multimedia presentation of the study you quoted: Oddball Creativity--Multimedia Report

Ambidextrous in early childhood--that was knocked out of me by those who feared my sinister powers.But I retained some unusual bimanual dexterity, including the ability to type more than 130 wpm on a qwerty keyboard by age 11. In my youth I eliminated that pesky backhand issue in tennis by switching hands--all my returns were forehand returns: drove my opponents to distraction and sometimes allowed me to defeat players of much greater overall skill; I also switch-hit in baseball. Curiously, I lack the typical left/right differential in bicep and calf muscle diameter as well.Another interesting correlation (DISCLAIMER: anecdotal, no scientific claim implied): Women are generally credited with a more balanced use of brain hemispheres. That research is often misunderstood (via the popular press left brain/right brain mishmash).Back in the days when I published, my manuscripts were often assumed to be the work of a woman (I used first initial/last name) when read by women editors, rarely so when read by men; one distaff editor explained that she made the assumption based on the "subtle emotional intelligence" of the work (perhaps I've changed since then... ). I think that is precisely the case. There is some data to suggest that the progression from genetic propensity to full blown psychosis requires an environmental trigger, prenatal (viral) or otherwise.
