This study examined the relationship between the number of tipped professions and national levels of extraversion, neuroticism and psychoticism in a sample of 21 countries. After two significant outliers were deleted, a simultaneous multiple regression analysis indicated that the number of tipped professions increased with national levels of extraversion and neuroticism and decreased with national levels of psychoticism. These findings are discussed in terms of their implications for: (1) the functions and underlying causes of a unique social-custom/economic-institution, (2) the validity of the EPQ as a measure of national personality, and (3) the breadth of phenomena that are influenced by personality traits.
