Dr. Justin Mogilski


Doctor of Philosophy in Evolutionary Psychology - Oakland University


Fostering shelter animals; video games; and difficult conversations.


My current program of research examines:

  1. Conflict resolution within consensually non-monogamous (CNM) romantic relationships (e.g., polyamory, open relationships, swinging),
  2. How evolution has shaped moral decision-making, and
  3. Individual differences in predatory intimate relationship behaviors.

I currently lead an international team of sexuality and relationship researchers studying CNM relationship maintenance strategies in 10+ countries.

My published work is openly available through:
