Individuals with left-wing and liberal views are overrepresented in British academia. Those with right-wing and conservative views are correspondingly underrepresented. Around 50% of the general public supports right-wing or conservative parties, compared to less than 12% of academics. Conservative and right-wing academics are particularly scarce in the social sciences, the humanities and the arts.
Though relatively little information is available, evidence suggests that the overrepresentation of left-liberal views has increased since the 1960s. The proportion of academics who support the Conservatives may have declined by as much as 25 percentage points since 1964.
The left-liberal skew of British academia cannot be primarily explained by intelligence. The distribution of party support within the top 5% of IQ is relatively similar to the distribution of party support within the general population.
The left-liberal skew may be partly explained by openness to experience; individuals who score highly on that personality trait tend to pursue intellectually stimulating careers like academia. And within the top 5% of IQ, openness to experience predicts support for left-wing parties.
Other plausible explanations for left-liberal overrepresentation include: social homophily and political typing; individual conformity; status inconsistency; and discrimination.
Ideological homogeneity within the academy may have had a number of adverse consequences: systematic biases in scholarship; curtailments of free speech on university campuses; and defunding of academic research by right-wing governments.
Recommendations include: raising awareness; being alert to double standards; encouraging adversarial collaborations; and emphasizing the benefits of ideological heterogeneity within the academy.
