People in high latitudes: the "Big Five" personality characteristics of the circumpolar sojourner.

The personality of the polar sojourner has been of interest to psychologists for a number of years. Using the NEO Five Factor Inventory, this study examined the general personality factors of the polar worker compared to a normative population, and how these factors differ according to the worker's occupational classification and the polar region in which he or she is working. It was found that polar workers scored higher than a normative group on all factors except Neuroticism. Comparisons across occupational groups showed that scientists were lower than military personnel on Extraversion and lower than technical/support staff on Agreeableness and Conscientiousness. The analysis by polar region indicated that Antarctic workers were higher than Arctic personnel on Extraversion, Agreeableness, and Conscientiousness. A group of Italian Antarctic personnel, completing a translated form of the NEO-FFI, scored lower than the rest of the polar groups on all factors. These findings are discussed in light of various features of the polar environment and Gunderson's 3-predictor model of polar adaptability.
