Introduction to Ethical Non-Monogamy: Concepts, Structures, and History

Ethical non-monogamy (ENM) is a term that covers a wide and varied territory: polyamory, open relationships, swinging, relationship anarchy, and a range of hybrid and emerging structures. Yet public understanding of this territory is often shaped by misconceptions, incomplete information, or exposure to only one of its many forms. A clear, grounded introduction to the full conceptual landscape is the foundation for any further engagement with the subject. By the end of this course you will be able to accurately define ethical non-monogamy and its major subtypes, distinguish the values and practical structures associated with each, and describe the historical and contemporary social contexts in which consensual non-monogamy is practised. What you will learn: - Definitions and distinctions: what separates ethical non-monogamy from infidelity, and the key differences between polyamory, open relationships, swinging, relationship anarchy, and other structures - The foundational values of ENM: consent, honesty, communication, and autonomy — and how these translate into different practices across different relationship models - The history of non-monogamy: from communal living experiments and free love movements to contemporary polyamory culture and academic research on ENM - Demographics and prevalence: what research suggests about how common consensual non-monogamy is and who practises it - Common terminology in ENM communities: metamour, compersion, NRE (new relationship energy), kitchen table versus parallel polyamory, and others - Monogamy norms and how they are socially maintained: why consensual non-monogamy remains stigmatised in many cultural contexts - ENM in different cultural and community contexts: how race, gender, sexuality, religion, and other identity dimensions intersect with non-monogamy practice - Research on the wellbeing, relationship quality, and outcomes of people in consensual non-monogamous relationships compared to monogamous ones This course works through carefully structured readings drawing on sociology, psychology, and cultural history, complemented by case examples from people in a range of ENM relationship structures. Reflection prompts invite you to engage critically with the material and identify your own questions and curiosities. A comprehensive terminology glossary accompanies the readings. This course is suitable for anyone who wants an honest, thorough, and non-judgmental introduction to ethical non-monogamy. No prior knowledge of the topic is required. Whether you are considering non-monogamy for yourself, newly in a non-monogamous arrangement, or simply curious about a social phenomenon you have encountered, this course provides a reliable conceptual foundation.
