Primes¶
- Overshoot and Collapse
- In incentive design, a reward is motivating up to a point, but incentive saturation past the ceiling inverts it — crowding out intrinsic motivation, inducing gaming — and the depleted secondary resource is trust or intrinsic engagement, which does not return when the over-strong incentive is removed.
This sourceOver-strong extrinsic incentives crowd out intrinsic motivation, depleting a reserve that does not return when the incentive is removed.

Mechanisms¶
- Incentive Floor Testing
- Its strength is that it prices behavior change empirically and exposes the perverse economics of over-rewarding: a big incentive that "works" may be buying gaming and eroding the intrinsic motivation that would have carried the behavior for free — the motivation-crowding effect.
This sourceFinds that expected tangible rewards contingent on performance or completion can undermine intrinsic motivation for the rewarded activity.

- Time Bank or Service Credit System
- Putting a number on help can crowd out the intrinsic and gift motives that made helping feel good — once neighbors ask "what's that worth in credits?", some of the warmth that powered the exchange leaks away.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. Neither this nor any other of the 3 citations of this work carries a recorded support check.
Was it audited? Yes. A second, independent pass read the citation against the article text and recorded a verdict.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
