In Simple Words
Imagine a teacher asking students to vote on which classmate gets a free laptop, where students naturally vote for their best friends rather than the most deserving student. When rankings directly control who wins a valuable grant, evaluator self-interest and social loyalty override honesty, causing respondents to systematically inflate scores for close peers.
Amravati peer-reporting groups
- Rankings did not affect grants
- Comparison accuracy
- Rankings affected grant chances
- 30% to 34% lower accuracy
Randomized reporting stakes, pooling the other reporting conditions. Rankings changed grant-winning chances in the high-stakes condition; no absolute accuracy levels are supplied.

When community members know peer evaluations directly determine who receives tangible financial benefits, personal incentives conflict with truthful reporting. Evaluators distort rankings to favor family members, close friends, or business partners, degrading the diagnostic value of peer information.
Participants
1,345 households in 274 peer groups of five microentrepreneurs in Amravati, Maharashtra, India.
Study Design
Randomized field experiment varying reporting stakes (High Stakes where top-ranked peers received extra lottery tickets vs. No Stakes) and visibility (Public vs. Private).
Results
Ranking report accuracy dropped by 30% to 34% when financial resources and grant allocations were at stake due to nepotism and peer favoritism.
Takeaway
Decouple peer-ranking surveys from direct, unadjusted grant allocation decisions to prevent strategic distortion and nepotistic reporting.
