People slightly below a goal work harder than those who have met or exceeded it — the reference-point-plus-loss-aversion engine shared across temporal-landmark motivation effects

The goals-as-reference-points account (Heath, Larrick & Wu, "Goals as Reference Points," Cognitive Psychology, 1999) holds that a goal functions as a reference point in the sense of prospect theory: outcomes below the goal register as losses and outcomes above it as gains. As restated in the 2023 four-sport replication, "research on goals as reference points shows that people who are slightly below their goal work harder than those who have reached or exceeded it, in a manner consistent with loss aversion." Effort is highest just below the reference point, where the marginal value of closing the gap is steepest.

This is the load-bearing mechanism under a family of otherwise separate findings. The individual Fresh Start Effect, Gersick's group-level midpoint transition, and the competitive halftime-deficit effect can each be read as one costume over the same engine: a temporal landmark supplies a reference point, and being below it triggers loss-aversion-driven effort. Naming the shared engine is what lets the family be evaluated as a unit rather than three coincidences.

That unit is only as sturdy as its engine. The sports instance did not replicate (claim-losing-leads-to-winning-fails-to-replicate-across-four-sports), and loss aversion itself is contested (Gal & Rucker, "The Loss of Loss Aversion," 2018 — not independently verified here). If the mechanism is context-dependent, so is the whole family. See moc-schema-change-and-restructuring.

The mechanism quote is taken from the replication paper's introduction, not from Heath, Larrick & Wu directly; the primary read is routed to question-verify-heath-larrick-wu-1999-goals-as-reference-points-primary.
