Numerous historians and social scientists have also credited Carey's outspokenness on her own multiracial heritage for facilitating public discourse surrounding race relations in the United States, as well as the advent of intersectional feminism, during the 1990s. As noted by Professor Michael Eric Dyson in his book, "Between God and Gangsta Rap: Bearing Witness to Black Culture," Carey's "refusal to bow to public pressure" surrounding the nature of her ethnicity exposed "the messy, sometimes arbitrary, politics of definition and categorisation" and "the racial contradictions at the centre of contemporary pop music" at the time. Sika Dagbovie-Mullins of Florida Atlantic University further credited Carey as being a trailblazing "multiracial heroine", remarking upon her ability to both exploit and critique "the various manifestations of the mulatta stereotype" throughout her career.
