abstract The objective of this study was to examine the possible linkages of economic-demographic (ED) and physiological (PHY) (nutritional and health status) variables with political attitudes. The data were collected through self-administered questionnaire, measures of height and weight, and food intake from a sample of 101 people from the city of Chittagong in Bangladesh. The subjects included the faculty of the University, researchers of the Forest Research Institute, and administrators of the Court House. Surveys were conducted in November and December of 1978. Biopolitics is actually an offshoot of the behavioral revolution of the 1950s; both attempt at studying human political behavior as the key to the understanding of the dynamics of politics. However, biopoliticists believe that in order to gain a thorough understanding of political behavior, researchers must go beyond socio-cultural variables and integrate knowledge from other sciences, particularly from biological science. This study was conceptually conducted from a sociophysiological approach which was a synthesis between socio-environmental and physiological approaches. According to the socio-environmental approach human attitudes and behaviors are conditioned by the social environment. According to the physiological approach, physiological conditions (nutritional and health status, for example), irrespective of social environment, determine the attitudinal make-up of a person. The synthesized approach of this study proposed that both socio-environmental and physiological factors influence attitudinal disposition. In keeping with the approach, three alternate hypotheses were formulated: (1) attitudinal variations were attributable to variations in social environment; (2) attitudinal differences were attributable to variations in physiological conditions; (3) attitudinal differences were attributable to both the factors acting together. Analysis of the data by statistical technique such as frequency distribution, Pearson’s product moment correlation-coefficient, and stepwise multiple regression indicated that attitudinal variations were associated with both ED and PHY variables. None of them was statistically strong enough to eliminate the influence of the other. Of the ED variables, education (self or father’s) appeared to be most powerful. Among the physiological variables, it seemed that health status indicators exerted more influence than nutritional status. The findings of the study confirmed the third hypothesis which postulated that attitudinal variations are influenced by both social and biological variables. Due to weak statistical correlations, it was felt that the integration of social and biological concepts—the vision of biopolitics—needed methodological clarity. However, the findings of this study did provide some empirical grounds for suspecting that physiological variables, along with socio-environmental, may have some influence on political attitudes. This matter needs to be more rigorously researched for more precise answers.
