In Simple Words
Imagine a local library paying teenagers $10 every time they visit the reading room. Instead of viewing reading as a valuable opportunity to learn, teenagers interpret the payment as a sign that sitting in the library is a boring job they are being hired to endure. They show up to swipe their attendance card and collect $10, but never open a book or engage with the reading materials.
Young jobseekers in 82 French youth centers
- Standard career guidance
- 7.3 counselor meetings
- Guidance plus cash offer
- 5.3 additional meetings
Over two years. Meetings recorded by youth centers. The study did not directly establish a loss of intrinsic motivation.
See source →Research question
Attaching financial rewards to developmental or guidance services can alter how participants perceive the purpose of those services, signaling that the activity is inherently unpleasant or burdensome. When incentives focus strictly on meeting attendance rather than genuine skill building, extrinsic rewards crowd out intrinsic motivation without driving real developmental effort.
Participants
N = 5,498 young unskilled jobseekers aged 18–22 across 82 Job Youth Centers in France (2,661 treatment, 2,837 control).
Study Design
Nationwide randomized controlled trial (RCT) tracking 24-month program engagement, workshop uptake, human capital investments, and labor market entry.
Results
Offering €250 per month increased meeting attendance by 5.3 meetings (ITT, p < 0.01) from a control mean of 7.3, costing an additional €1,530 to €1,868 per participant over two years. However, treatment generated precisely zero impact on overall human capital investment (index effect +0.019, p > 0.10) and caused a temporary 3 percentage point decrease in full-time employment during the first six months (p < 0.05).
Takeaway
Design social policy incentives around end-goal achievement milestones rather than intermediate attendance compliance to avoid crowding out intrinsic motivation for self-improvement.

A study that uses chance, like drawing lots, to decide who receives each option being compared. Researchers compare the groups’ outcomes to estimate the effect of those options.
ExampleA lottery assigns volunteers to a training programme or a comparison group. Researchers then compare their outcomes.
