Stylized facts:
- Academia has always been predominantly left, but has become more and more so over time. This imbalance is stronger in Social Science and Humanities (SSH) than in STEM, but even in STEM the faculty are predominantly left of center relative to the general population.
- Leftists are becoming more and more intolerant of opposing views.
- Young academics (PhD students and junior faculty) are the least tolerant of all.
In my opinion the unique importance of research universiites originates from their commitment to the search for Truth. This commitment is being supplanted by a focus on social justice, with extremely negative consequences.
