School of Emergent Priorities researchers estimate what customers actually choose between at a swap-and-go gas cylinder cage, and find a presentation standard built from the attributes they price highest and audited quarterly.
A discrete-choice study of 214 forecourt customers, and the national loading standard an exchange network wrote from the results
Two hundred and fourteen people at a service-station forecourt were each asked, eighteen times over, which of two gas cylinders they would take out of the cage. Towards a Cage-Loading Standard, released today by the School of Emergent Priorities, turns their answers into a price. A collar sticker still legible enough to read is worth 41 cents against the swap fee. The certification date printed on that sticker is worth six.
The University regards the work as characteristic of the School’s interest in how a preference, once measured, becomes an instruction. The exchange network’s revised loading standard now prescribes a presentation order taken from the three attributes customers priced highest, and audits that order every quarter.
The interesting part is not what people chose. It is what the choosing was then used to arrange.

The study pairs a designed choice experiment with a follow-up count of front-row cage positions across 34 forecourts, bringing stated preference and physical arrangement onto a single footing. Dr Petra Umbile, Postdoctoral Fellow, said the exercise had shifted the questions the group asks of its own instruments: “We are practised at asking whether a measure is sound. This one asked what a measure gets used for once everybody agrees it is.”
