It's pretty well understood that there's an unfortunate bias towards white men in their early 20s. This is a pervasive sampling problem across all human studies because most researchers have historically been at universities. So their pool of subjects has naturally been nearby college students.

Just as those are the people who have historically been doing that research, the people who they have studied have been drawn from the same population. Over and over we find that problems from the assumption that the young, white, male college student is a model of "normal" for all of humanity.

Honestly, it's such a pervasive finding in medicine, psychology, and sociology that I think it says more about your relative inexperience in those areas than anything else.
