**6. Conclusions**

This paper reviewed theoretical perspectives on and emerging trends in the suppression of academic scholarship. It provided several unique contributions to understanding suppression. First, we reviewed legal, moral, and social issues in distinguishing among free speech, free inquiry, and academic freedom. Second, we showed that, because academia is a social reputational system, it is especially vulnerable to groupthink and a stifling intellectual conformity, despite lip service or even bona fide protections resulting from academic freedom statements and tenure.

Third, we pointed out that protections and freedoms such as free inquiry and free expression, which are often used in ways plausibly viewed as interchangeable in much social discourse, can and are often in tension and conflict. The premier case is that of a denunciation mob; they are exercising their legal free speech rights, and, if they are successful, they will suppress certain ideas. We then reviewed theoretical perspectives on and the history of moral panics, which have long played a role in suppressing certain ideas. Finally, we reviewed a series of real-world cases where academics have been fired, successfully punished in ways short of firing, and targeted unsuccessfully for punishment by outrage mobs for their ideas.
