Is there a branch of academic philosophy that specifically includes the study of what makes a person believe in something?

If you mean "causes" at the level of precedent individual determinants, that's psychology.

If you mean "causes" at the level of determinants in communicative interaction, that's rhetoric.

If you mean "causes" at the level of precedent systemic determinants, that's sociology or anthropology or political science.

Academic philosophy intersects with all of these, to varying degrees.
