Personality as the basis for theoretical predilections.

Four groups of behavioral scientists with divergent theoretical persuasions--43 sociobiologists, 25 behaviorists, 35 personality psychologists, and 16 human developmentalists--showed significantly different mean scores on two measures of philosophical assumptions: the World Hypothesis Scale (WHS) and the Organicism-Mechanism Paradigm Inventory (OMPI). The OMPI, which appears to be more psychometrically sound than the WHS, showed in 12 additional groups of subjects (N = 622) consistent correlations with self-report and peer ratings of personality, intellectual and interpersonal style, and occupational interests. Taken together, the two studies suggest that behavioral scientists' philosophical presuppositions (e.g., whether reality is better described by stable, isolated elements or changing holistic patterns; and whether persons are passive and reactive or purposive and active) may mirror their views of themselves.
