A new Slop University paper reports a regression-discontinuity analysis of an allotment federation's seniority cutoff for full-size plots, finding it drives a jump in shed-materials spending while participation measures do not move, and the coefficient has since been adopted by the Anticipatory Capability Fund's readiness scoring.
A regression-discontinuity study of an allotment federation's seniority cutoff now scores an unrelated University grant round's readiness criterion.
Three years is the number the Anticipatory Capability Fund has begun asking every future application to reckon with, after a paper from the School of Emergent Priorities traced it back to an allotment waiting list.
The paper applies a regression-discontinuity design to twelve suburban allotment associations sharing one waiting list, comparing outcomes for members whose tenure on the list fell just either side of the associations’ bylaw threshold for a full-size plot. Materials-account spend jumped sharply once tenure cleared the threshold; entries in the district produce show and attendance at working bees did not move by a distinguishable amount, and four placebo cutoffs recovered no comparable jump at all.
The specificity of that result is what caught the Fund’s attention. Its readiness axis, used to score every application for project funding, has adopted years-on-a-waiting-list at first allocation as a scored sub-criterion, regardless of an applicant’s field.
The threshold behaves exactly as a tenure-security account predicts, which is either reassuring or slightly worrying depending on how much weight you think a garden shed should be asked to carry.

“A coefficient that travels this cleanly is exactly what the readiness axis was built to recognise,” said Professor Verity Marris, Director of the Trajectory Analytics Group, “and we will be watching with interest to see how far it carries.”
The work continues the School’s ongoing attention to the rules a club, committee, or association writes for itself long before anyone thinks to study them.
