The aim of the study was to assess the heritability as well as the personality predictors of socio-economical attitudes. Attitudes were examined on two separate dimensions: moral conservatism - liberalism and free market economy - state interventionism. The studied sample comprised two groups of subjects: 242 twin pairs aged 18 to 25 (119 monozygotic and 123 dizygotic same-sex twins reared together), and 197 male and female students of the technical university aged 19 to 25. The authors detected a substantial input of the genetic factor exclusively in the variability of results on the conservatism-liberalism scale (0.28). Results on both scales were to a large extent explained by the impact of shared environment, and, to a lesser extent - of nonshared environment. Results of regression analysis have shown that only two personality traits: neuroticism and agreeableness may serve as best predictors of economical attitudes (high level of both dimensions was associated with state interventionism).
