I do not know what it would be if not systemic racial bias within our society. In the mental health field, we have been mandated to learn, train, and practice multicultural competencies for my entire career. It's enshrined in our code of ethics, and we are formally evaluated on these competencies regularly as a condition of maintaining licensure.
There are very robust professional groups developing specialized programs for every group you can imagine. In my clinic alone, we have groups that specialize in Black, Latine, East Asian, Southeast Asian, South Asian, Asian American, First Generation, Transgender, Masculinity, Immigration Impacted, System Impacted, Neurodivergent, etc. mental health concerns. We also have multicultural and culture-specific trainings and consultations on weekly basis.
