An excellent infographic about how Western research skews results, from Best Psychology Degrees:
Yes, but the intended audience is from the developed West as well. I don’t think many try to juxtapose a study on dating habits of college students to 19 year olds in a Sudanese village.

But to reduce this bias to “culture” also reveal some problematic biases. A report a few years ago better pointed out that this group is also fairly rich and educated (among other things).
