Queue Fairness Is a Moralised Norm, Not a Practical One
Research on queuing psychology finds people care more about first-in-first-out fairness being observed than about actual wait time, and violations produce reactions wildly out of proportion to the seconds lost. That disproportion is the point — a proportionate response would deter nothing. Queues have no paid enforcer, so participants' willingness to punish at personal cost is the entire enforcement infrastructure, which is why the norm is defended even when nothing is scarce.
Queue fairness behaves like a **moral** value rather than a practical one. Research on queuing psychology finds that people care more about first-in-first-out fairness being observed than about how long they actually wait — and violations produce reactions out of all proportion to the time lost. ## The disproportion Someone cutting into a line ahead of you might cost you thirty seconds. The response — tutting, glares, verbal confrontation, occasionally physical escalation — is not calibrated to thirty seconds. It is calibrated to the fact that a norm was broken. This is not irrationality. It is **norm enforcement**, and the disproportion is the point: a response proportional to the harm would not deter anything. Humans behave in these settings as *strong reciprocators* — deferring to the norm themselves and punishing defectors at cost to themselves. See Altruistic Punishment: Paying a Personal Cost to Enforce a Norm. The moralised character shows up in the language. Queue-jumping is described in the vocabulary of cheating and theft rather than inconvenience, and the offender is characterised as a *type of person* rather than as someone who made an error. ## Why queues in particular Queues are an unusually pure case of a fairness institution. They allocate a scarce good by a single legible rule, with no enforcement mechanism other than the participants. Nobody is paid to police a line. It works entirely because everyone in it is willing to defend it, which means the willingness to punish *is* the infrastructure. That also explains why the anger persists when the queue is not scarce at all. The norm is defended as a norm, because a norm that is only defended when the stakes are high does not survive. ## The consequence for arguments about place-holding Because the reaction is moral rather than practical, it does not respond to the practical defence. Pointing out that a marker in a line costs nobody any time is true and does not address the objection, which is about whether a claim was legitimately earned. That is the setup for a fight that cannot resolve: two coherent and incompatible views of what earns a place.
