[4] He uses this data to support his claim that a substantial percentage of all hate crime allegations must be hoaxes, given that, per his analysis, only about 7,000 reported hate crimes take place in a typical year, and at most, 8–10% of these receive the national or regional reporting that is required for inclusion in his data set.
[5] In the wake of the Jussie Smollett hate crime hoax, Reilly authored an editorial outlining his case in USA Today.
[11][12] Reilly argued for the social value of diversity by contending that it makes life "more interesting, civilized, and fun" and used published research to point out that mono-racial societies (such as Bosnia and Somalia) are often no more peaceful or less conflicted than multi-racial societies because of the greater prevalence of tribal in-fighting within them.
Reilly's PhD dissertation, submitted in 2015, was The Effect of Racial Status and Other Core Characteristics on Collective Self-Esteem: A Quantitative Test of Divergent Theories of Identity Valuation.
