I was alerted to this problem by a fascinating article by Maha Bali in the Chronicle of Higher Education, Inclusive Citation: How Diverse Are Your References?. Inclusive citation involves searching outside your usual sources and actively connecting with colleagues from different parts of the world and with different cultural backgrounds to yourself. The article gives some practical advice about expanding your horizons by reviewing your present networks and sources and then connecting with people outside that sphere. Even if you have one contact from outside your standard sources, find out who they network with and cite and work from there. You will undoubtedly expand your horizons by doing so.
Have a look at the reading lists you recommend for students. Are we reinforcing a cultural bias and demonstrating to students which types of academic sources are the "right" ones to cite.
If your citations aren’t diverse and inclusive enough, chances are, you’re missing some valuable perspectives. Chances are, you’ll learn something new and it will resonate with you. And eventually, it will become habit, and you won’t have to count references any more because you will naturally already have a diverse list of authors whom you respect and read regularly.
