Moreover, in a classic text, Converse went even further by emphasizing that education 'is everywhere the universal solvent, and the relationship is always in the same direction. The higher the education, the greater the ''good'' values of the variable'. 4 This idea is, explicitly or implicitly, widely accepted in political behaviour research and the relationship between education and political participation is perhaps the most well-established relationship that exists in research on political behaviour.However, recently a number of studies have started dealing with the question of whether education is a direct cause for political participation or merely works as a proxy for other factors. 5 The question about causality has become disputed in political
