Abstract

Science fiction about intelligent aliens has long imagined a science of sociology with typologies that apply universally, much as the periodic table of the elements applies to atoms on all planets. The GRIN model purports to offer such a universal typology. This study offers the first instrument to measure its manifestation in humans: the Gadfly-Relational-Institutional-Negotiator Self-Quiz (GRINSQ). It reports evidence of the GRINSQ's reliability, as well as its structural, content, convergent and pragmatic validity, including relationships to the Moral Judgment Test (MJT), Moral Foundations Questionnaire (MFQ), and Big Five personality traits. The evidence supports the hypotheses that humans specialize by GRIN-type, and that this specialization relates to differences in personality, morality, political orientation, career, religion, family type, and identification with crime.
