What drives the link between university study and attitudinal change?

What drives the link between university study and attitudinal change? While research shows that obtaining a degree tends to make students more socially liberal, little is known about what drives this effect. We address this ‘how’ question by testing the socialisation-based mechanisms through which university study may shift attitudes; combining individual-level panel data from the British Election Study Internet Panel with university- and constituency-level data about where respondents studied to estimate sub-group effects. Our results suggest that students tend to shift their attitudes subtly in a leftward and liberal direction whilst at university, but that this average effect is larger for: those who graduate younger, who study STEM and other non-HSS subjects (social attitudes only), who move away from home to study, who attend single campus institutions, and who live in ‘university towns’ and ‘cosmopolitan London’ while studying (all economic attitudes only). Overall, we find evidence to suggest that the socialisation experiences individuals are exposed to while studying have important shaping effects on their attitudes.
