How common consensual non-monogamy is becoming (and why)
Chris and Justin start by situating consensual non-monogamy (CNM) in the broader dating landscape, including prevalence estimates and how many people try it versus stick with it. Justin connects the trend to cultural shifts like individualism, delayed marriage, and expanded life options beyond traditional family formation.
- •Estimated prevalence: many try CNM, a smaller percentage maintain it long-term
- •Cultural/economic changes reducing marriage as a necessity
- •Delayed marriage/family and career focus creating space for alternative arrangements
- •CNM framed as a strategy that may fit modern motives better for some people
- 1:39 – 6:24
Sex differences in interest and motivations for CNM
They explore whether men and women differ in desire for CNM and why. The discussion contrasts short-term sexual opportunity motives (more common among men on average) with concerns about commitment and potential interest in multiple emotional bonds (more common among women on average).
- •Men report higher interest in CNM on average, but the gap isn’t enormous
- •Men’s motives often tied to increased sexual opportunity and casual sex interest
- •Women’s lower average interest linked to commitment/partner investment concerns
- •Polyamory can appeal via emotional support networks and practical benefits (e.g., childcare)
- 6:24 – 8:56
Jealousy, mate-guarding, and why CNM often breaks down
Chris and Justin identify jealousy as a central friction point and discuss how jealousy differs by sex (sexual vs emotional jealousy). Justin explains CNM’s coordination problem: adding additional partners introduces rivalry, uncertainty, and resource/attention competition that monogamy structurally avoids.
- •Men tend to show more sexual jealousy; women more emotional jealousy (in monogamy data)
- •CNM failure risk rises with additional partners and complex coordination
- •Third-party dynamics create competition and new demands
- •Monogamy reduces rivalry by removing extra-partner competition from the system
- 8:56 – 12:54
Mate value disparities: who wants CNM and who predicts jealousy
They examine how perceived mate value might shape openness to CNM and anticipated jealousy. Justin references preliminary patterns suggesting higher mate value individuals show more interest and project less jealousy, linking to perceived security and willingness to take risks.
- •Higher relative mate value may correlate with greater interest in CNM
- •Higher mate value individuals may expect less jealousy (projection vs reality caveat)
- •Security in attachment and attractiveness can increase risk tolerance
- •Discussion connects to broader risk-taking logic beyond dating
- 12:54 – 16:59
Who practices CNM: personality traits, demographics, and misconceptions
Justin outlines what research suggests about predictors of CNM involvement, emphasizing openness to experience and sociosexuality. They also challenge the assumption that CNM is only about sex, noting some people pursue multiple attachments and emotional needs rather than novelty alone.
- •Big Five: openness to experience is the standout personality correlate
- •Higher rates among LGBTQ+ individuals (demographic predictor)
- •Unrestricted sociosexuality predicts CNM, but CNM isn’t only about sex
- •Some people use CNM to meet diverse emotional/intimacy needs
- 16:59 – 19:15
Common CNM configurations: polyamory, swinging, and “open” relationships
They define major CNM categories and why counting them is difficult. Justin contrasts polyamory’s emotional-attachment emphasis with swinging’s sex-focused, more private culture, and highlights the stigma that complicates measurement and public understanding.
- •Three common research buckets: polyamory, swinging, open relationships
- •“Open” is broad and can mean many rule-sets
- •Polyamory: multiple emotionally attached relationships (often sexual too)
- •Swinging: more sex-focused and often more secretive
- •Stigma leads to underreporting and measurement challenges
- 19:15 – 23:10
One-sided openness and the “one penis policy”: jealousy and fairness tensions
Chris raises the manosphere claim of one-sided non-monogamy; Justin notes limited direct data but discusses the common ‘one penis policy’ dynamic. They connect it to paternal certainty and male jealousy, while also noting how such policies can feel restrictive and inequitable to women, creating new conflict.
- •One-sided arrangements are hard to quantify with existing surveys
- •“One penis policy” as a recurring configuration and its evolutionary logic
- •Addresses men’s cuckoldry concerns but can generate female restriction/resentment
- •Solves one partner’s anxiety while potentially increasing the other’s
- •Different CNM rule-sets attempt to manage jealousy asymmetrically
- 23:10 – 26:48
How CNM conflict differs from monogamy: secrecy, STIs, and childcare complexity
They compare conflict sources across monogamy and CNM, arguing many baseline conflicts remain but CNM adds unique stressors. These include managing additional relationships, STI risk, parenting logistics, and reputation costs—especially because secrecy tends to harm relationship health.
- •Baseline couple conflicts remain similar (plans, living, fights)
- •CNM adds: fear of loss intensified by additional partners
- •More sexual network density increases STI-management demands
- •Childcare coordination becomes more complex with more adults involved
- •Reputation management and secrecy can damage relationships
- 26:48 – 29:35
The Multi-Relationship Maintenance Strategies Scale: why agreements matter
Justin introduces his work on a set of maintenance strategies people report using to make multi-partner relationships function. They begin with exclusivity agreements—explicitly defining rules and revisiting them—while acknowledging the measurement nuance that this factor didn’t persist statistically in their final scale despite community endorsement.
- •Framework: strategies intended to improve CNM relationship maintenance
- •Exclusivity agreements: clarify expectations early to avoid mismatches
- •Rules vary (sex-only vs love-only boundaries), and can be hard to separate in practice
- •Revisiting agreements is crucial because attachments and desires change over time
- •Community-nominated “best practices” don’t always map neatly onto statistical factors
- 29:35 – 32:20
Attraction disclosure: telling the truth to reduce speculation spirals
They dive into attraction disclosure—sharing attraction to others instead of hiding it—and why it correlates with better outcomes. The core claim is that secrecy creates an information vacuum that partners fill with worst-case simulations; transparent disclosure can lower uncertainty and preempt escalating mistrust.
- •Attraction disclosure explained: proactively admit outside attraction
- •Strong correlations with relationship satisfaction and lower conflict
- •Secrecy fuels anxious “simulations” about replacement and betrayal
- •Causality unclear (cross-sectional data), but behavior plausibly improves trust
- •Practice appears beneficial even among monogamous participants
- 32:20 – 36:44
Compersion and jealousy regulation: cultivating alternative emotional responses
Justin defines compersion as feeling happiness for a partner’s positive experiences with someone else, and argues it may require deliberate reasoning rather than arising automatically. They connect it to secure attachment and then pivot to jealousy regulation—especially the importance of being able to talk openly about jealousy to resolve it.
- •Compersion: joy at a partner’s positive experience with another person
- •Likely less spontaneous than jealousy; may require cognitive work
- •Security of attachment may enable compersion
- •Jealousy regulation emphasizes freedom to communicate jealousy openly
- •Open discussion reduces solo rumination and catastrophic interpretations
- 36:44 – 43:06
Managing sexual jealousy in practice: avoid avoidance, use reframing and mindfulness
They outline strategies for dealing with sexual jealousy, starting with what not to do. Justin argues avoidance is often the worst tactic, and suggests cognitive reframing and mindful observation—checking whether jealousy is serving its relationship-protective function or becoming chronic and destructive.
- •Avoidance is framed as a particularly harmful coping strategy
- •Cognitive reframing: consider how a partner’s other relationship could enrich life
- •Potential benefits cited: partner returns happier; more personal time; healthy distance
- •Mindfulness-style approach: observe jealousy rather than act out possessiveness
- •Evaluate whether jealousy is functional (problem-solving) or corrosive (chronic)
- 43:06 – 51:39
Threesomes, hierarchy, sexual health, reputation, and resource distribution (the remaining strategies)
Justin runs through additional maintenance strategies and why they matter: partner hierarchy (primary/secondary), sexual health maintenance (testing/safer sex), sharing extra-pair sexuality (including a partner in outside sex), reputation management (secrecy), and resource distribution (time/attention/money across partners). Together, these address predictable CNM pain points like neglect, uncertainty, and unequal investment during “new relationship energy.”
- •Partner hierarchy: primary/secondary structures vs non-hierarchical ideals
- •Sexual health maintenance: testing norms, contraception, reducing network risk
- •Sharing extra-pair sexuality may reduce conflict by making benefits mutual (but can backfire emotionally)
- •Reputation management: hiding CNM can limit social integration and harm relationships
- •Resource distribution: manage time/attention fairly; counter ‘new relationship energy’ neglect
- 51:39 – 1:13:22
CNM’s branding problem, cultural condemnation, and ancestral mating myths
They zoom out to why CNM is stigmatized: jealousy risks, social instability fears, perceived threats to monogamy, and concerns about sexual ‘redistribution’ and intrasexual competition. They then discuss evolutionary perspectives on ancestral mating systems—arguing humans likely exhibited a contextual mix of monogamy and non-monogamy shaped by ecology and resource concentration.
- •Stigma partly driven by legitimate perceived risks: jealousy, aggression, chaos
- •Fear CNM threatens monogamy by making alternatives salient and tempting
- •Concerns about sexual competition, inequality, and ‘harems’ (debated)
- •Evolutionary view: humans likely practiced a mix depending on environment and wealth concentration
- •Modern conditions (women’s independence, resource access) may alter classic polygyny dynamics
- 1:13:22 – 1:16:19
What Justin is researching next and where to follow his work
Justin closes by outlining future research directions: publishing existing datasets, studying parenting in CNM, and investigating how CNM can go wrong—particularly through exploitation by people with dark personality traits. He shares where listeners can find updates and academic outputs.
- •Next steps: write up and publish a large backlog of collected data
- •Parenting in CNM is understudied; ongoing work with Elizabeth Sheff
- •Goal: ‘steelman’ CNM best practices and then study failure modes
- •Interest in exploitation risks tied to dark triad traits (narcissism, psychopathy, Machiavellianism)
- •Where to follow: Twitter/Facebook for announcements; ResearchGate for academic updates
