I'm studying the effect criminology and the other social sciences have on racial bias compared to other majors. If there is a correlation I want to project this towards police as a critical area of study for police officers in higher education.
I'm not sure that one exists. In the first instance you might want to consider how you would measure it and then be able to attribute it to the influence of social sciences/criminology. I think it would be very difficult to control for the pre influence of environmental factors that may have already influenced such as bias.
It might be worth looking at some of the references in these papers; some might give too narrow a scope:
