MWITA-EBRO-2026-009 · Evidence A · P1
Performance-contingent referral rewards induced high-ability participants to refer higher-performing contacts, whereas larger fixed referral payments did not improve referral quality; high-ability referrers possessed useful private information but used it selectively when incentives aligned.
What this does not establish
This is a laboratory-style casual-work experiment, not an employer's production workforce; it does not establish hiring, retention, demographic equity, or the effect of ordinary employee-referral bonuses when job performance is multidimensional or delayed.
Counterevidence & uncertainty
More money as a fixed finder's fee did not solve the screening problem; reward contingency and referrer ability, not bonus size alone, determined informational value.
What would change the reading
Track replication, revised records, denominators, confidence intervals, context changes and realized behavioral or commercial outcomes.
