Politics of university academics

UK universities have always been left-wing, but they have become overwhelmingly so in the past 50 years. Is there enough cognitive diversity and disagreement at universities? What consequences does this have on the research being published (or not)? 

Political diversity has declined in UK universities over the past 50 years. Data shows that in 2015 almost 70% of academic staff (professors and lecturers) reported left-leaning political views. 

This lack of diversity has the potential to affect research emerging from universities. A diverse group of scholars will tend to cancel out each other’s confirmation biases when assessing or reviewing research. But less political diversity among academics can undermine the quality and rigour of research produced by universities. Research has shown that in the peer-review process of academic articles, reviewers are more inclined to accept articles which confirm their views and beliefs, including political views, and are more critical of research which challenges their views.

Lack of political diversity also has potential impacts on students. Graduates may emerge from university with an inaccurate or distorted view of the political spectrum. Low cognitive diversity among university professors and lecturers could also hinder the development of critical thinking in students.
