The Personality Assessment System Foundation exists to further the study of the relationship between intelligence and other personality variables as they interact to influence human behavior. In this endeavor we follow the example set forth by John Gittinger, who first developed the Personality Assessment System. To this end we attempt to examine current thinking on these topics, to stimulate research which will enhance our understanding, and to foster a sense of community among all parties who seek to pursue interest or study in these areas.
