The Patternists specialized in cerebral asymmetry. With grossly expanded right-brain hemispheres, they were highly intuitive, given to metaphors, parallels, and sudden cognitive leaps. Their inventive minds and quick, unpredictable genius had given them a competitive edge at first. But with these advantages had come grave weaknesses: autism, fugue states, and paranoia. Patternists grew out of control and became grotesque webs of fantasy.
