The Deggans rule, or the Deggans test, is a test for analysis of depiction of people of color as characters in fiction works. Coined by TV critic Eric Deggans in 2008 for an NPR discussion on the impact of the Bechdel test, it tests the viability of POC characters along the following lines:

  1. At least two non-white human characters in the main cast...
  2. a show that's not about race.

TV Tropes covers example works of fiction which comply with the Deggans rule.
