This puzzle bothered behavioural economists: You offer a friend $10 to help you move a sofa, and he is offended. You offer nothing and simply ask for help, and he shows up on Saturday with coffee and good humour. Everyone intuitively senses what went wrong in the first scenario, but the field has never had a fully satisfying account of the mechanism. Jara-Ettinger and Dunham (henceforth JED) finally provide the connection: behavioural economics and social psychology have been studying stance deployment for decades without realizing it. The JED framework gives this scattered empirical landscape the theoretical backbone it has been missing and, as we argue, explains why parts of that landscape failed to replicate.

The deepest connection lies in Margaret Clark and Judson Mills’s (Reference Clark and Mills1993) research programme on communal and exchange relationships: when you help a friend, you give because they need something; when you help a business partner, you give because they gave first, or because you expect them to give later. Communal and exchange logics generate very different downstream consequences when they get mixed up. Monitoring contributions in a friendship – Clark and Mills’s term for tracking who gave what to whom – feels like a betrayal rather than just awkward social behaviour, because it signals that you have stopped reading your friend’s helpfulness as an expression of genuine care and started reading it as the discharge of a role obligation.

The JED framework explains exactly why this reclassification carries such weight. Exchange relationship behaviour follows naturally from the institutional stance: behaviour gets attributed to role-based entitlements, tracking is appropriate because role compliance is what matters, and violations signal role-departure. Communal relationship behaviour follows from the mentalistic stance: helpfulness gets attributed to accurate perception of the other’s needs and genuine desire to meet them, and tracking is harmful because it overwrites a personal attribution with an institutional one. When your friend starts keeping score, the offence runs deeper than a mere norm violation because an entire attributional framework has shifted. The two stances generate fundamentally different answers to the question of what the same behaviour reveals about the person performing it. JED supply Clark and Mills’s architecture, explaining why the two modes feel so qualitatively different and why crossing between them carries such costs.

Market mindset research adds another layer. People turn toward market relationships specifically when they feel a threat to personal control and need predictability in their social environment (Gasiorowska & Zaleskiewicz, Reference Gasiorowska and Zaleskiewicz2021), and more anxiously attached individuals are especially likely to do so under threat (Gasiorowska & Zaleskiewicz, Reference Gasiorowska and Zaleskiewicz2023). The structured, rule-governed quality of transactional interactions becomes psychologically attractive precisely when communal relationships feel too uncertain or demanding, a finding that maps directly onto JED’s argument that the institutional stance reduces the cognitive demands of full mentalistic inference.

When both stances are simultaneously active, JED predict interference rather than a clean blend. This pattern has a vivid real-world signature: the moral suspicion surrounding philanthropic entertainment – the genre of YouTube creators who fund surgeries and give away cars while filming everything for millions of viewers – where identical charitable outcomes attract criticism simply because the transactional structure is too explicit to suppress (Białek, Reference Białek2026). Newman and Cain (Reference Newman and Cain2014) demonstrated the laboratory analog: charitable acts that also benefit the donor receive less moral credit even when the net good is greater. The same logic that explains co-activation interference also predicts which behavioural economics findings will hold under replication and which will not.

Stance-based effects tend to be most robust when a manipulation genuinely places participants inside real role structures and real relational stakes, but most fragile when it tries to activate a mindset through incidental semantic exposure without changing anything about the actual relational context. Vohs and colleagues’ money priming paradigm exemplifies the fragile end: participants count Monopoly money or unscramble sentences containing financial words, manipulations that alter semantic context without embedding participants in any actual institutional relationship, and large pre-registered replications failed to reproduce the originally reported behavioural effects (Rohrer, Pashler, & Harris, Reference Rohrer, Pashler and Harris2015; Vohs, Mead, & Goode, Reference Vohs, Mead and Goode2006, Reference Vohs, Mead and Goode2008).

Gneezy and Rustichini’s (Reference Gneezy and Rustichini2000) daycare study is more instructive because it looks like genuine contextual manipulation: introducing a fine into an ongoing parent–caregiver relationship explicitly reframes the interaction in transactional terms, turning late pickup from a breach of trust into a paid service. The original field study produced the famous counterintuitive result, with late pickups increasing after the fine was introduced and not recovering after its removal. But Metcalf, Powell, and Zhong (Reference Metcalf, Powell and Zhong2020) found the opposite pattern in a survey-based replication, with fines reducing non-compliance and effects reversing cleanly. We suggest that the JED framework explains this divergence. Vignette participants evaluate a hypothetical scenario involving strangers rather than navigate a real relationship with caregivers they see daily, and we hypothesize that this strips away the embeddedness in an actual role relationship that the institutional stance requires to engage. If so, the methodology was rigorous but theoretically misspecified, and what a study needs to replicate a field finding is not just methodological rigour but genuine embeddedness in an actual role relationship. This tells us not just why some studies fail to replicate, but what a study needs to contain if it genuinely deserves to succeed.

One might ask whether mapping behavioural economics onto the JED framework is merely relabelling – attaching new vocabulary to patterns researchers already understood. We think not. The JED framework specifies the mechanism rather than the pattern. Prior accounts described that market norms displace social norms; the institutional stance explains why the substitution is so cognitively abrupt, why the two logics cannot simply coexist, and why embeddedness in a real role relationship is a prerequisite rather than a convenience. This clarifies why some findings have proven robust for thirty years while others evaporated under replication, and why disparate phenomena share a common cognitive source. The JED framework explains this uneven landscape and tells us what to do differently.
