The mind of an architect

In the early 1950s, the Institute of Personality Assessment and Research (IPAR) at the University of California, Berkeley began developing new and different ways to analyze personalities. The scientists at IPAR attempted what many thought was impossible: to study creativity in a methodical and scientific way, working to determine what specific personality traits make certain people creative.

IPAR found that creative people tend to be nonconforming, interesting, interested, independent, courageous and self-centered, at least in general. Creatives could make unexpected connections and see patterns in daily life, even those lacking high intelligence or good grades.
