Introduction: In recent years, the number of deplatforming attempts has increased at universities. Deplatforming is an attempt to block a person from speaking when certain groups find their content to be objectionable. An institution's culture of free speech may affect the number of deplatforming incidents. Methods: This study utilized data from a new database of deplatforming incidents on campus. The data were tested for correlations in relation to an institution's free speech ranking and its level of DEI (Diversity, Equity, and Inclusion) staffing. Results: These initial results show a negative relationship between free speech ranking and deplatforming incidents, and a positive relationship between DEI staffing and deplatforming incidents. Discussion: Institutions face the challenge of balancing an inclusive and equitable environment with the preservation of robust intellectual diversity and academic freedom. Finding this balance requires a thoughtful and deliberate approach that considers the nuances of promoting diversity, equity, and inclusion while safeguarding the principles of free expression and open dialogue. Limitations: These results were only for Power 5 universities in the United States. A more diverse sample may show different results. Conclusions: The culture of an institution is related to the number of deplatforming incidents that take place. This culture can be examined via its commitment to free speech and to its DEI staffing levels. Initial results show that these two factors have a relationship with the number of deplatforming incidents.
