Proportion of participants paying back at least $0.10 in Study 3 for all conditions. Proportions are shown as markers for each condition with bars corresponding to the 99% CI (confidence interval). The payback proportion is relative to the number of participants accepting the higher amount. Payback rates are presented unfiltered (larger markers) and filtered (smaller markers). Arrowheads mark the estimated rates of payback when replacing expected zero payments (10% of participants) with observed rates from the corresponding clear conditions.
