Practice citation counting: literally count how many women, poc, and other marginalized folx are included in your references. Count how many nontraditional sources you cited. Google the authors to see who they are if you need to. Don't make assumptions about gender. Do your research.
Push against the narrow definition of academic scholarship that is exclusive, misogynistic and racist. Just because someone's work has not been heavily cited does not mean it does not have value. Strive to towards citation politics that are feminist and anti-racist.
There are different kinds of authority. Consider the context in which you are writing and determine what kind of expert you need? For example when might a government site not be as reliable as a personal narrative?
There are more contributors to research than just the author(s). Take a critical look at the methodology section to see who contributed and who didn't.
