Consider a racist stereotype you have encountered in your daily life or in the media that has been used to explain socioeconomic differences between racial groups. How did the presenter explain the existence of the stereotyped trait or behavior?
Now take the perspective of a biologist who has studied chronic stress, epigenetics, or a similar research area. To what extent does that science help us distinguish between traits or behaviors that are caused by biology and those which are caused by the impacts of racial bias on particular individuals or groups? What sort of scientific evidence supports an alternative interpretation of the stereotype you have described? If you can’t find any evidence, then what sort of hypothesis could you construct to work towards an experiment to debunk the racist stereotype?
