What was done
Six experimental and natural field studies examined whether individuals underestimate others' willingness to comply with direct requests for help. Studies 1–3 compared predicted versus actual compliance across diverse request settings. Studies 4 and 5 experimentally manipulated participants' perspective as either help seekers or potential helpers. Study 6 tested the underlying cognitive mechanism by measuring attention to the instrumental costs of helping versus the social costs of refusal.
What was found
Participants underestimated the likelihood that others would comply with a direct request for help by as much as 50% across experimental and field contexts. Perspective manipulation confirmed that being in the help-seeker role elicited this bias. Help seekers focused primarily on the instrumental costs of compliance (costs of saying "yes"), while potential helpers were heavily influenced by the social costs of refusing direct requests (costs of saying "no"). Specific sample sizes, confidence intervals, and effect sizes beyond the 50% figure were not reported in the abstract.
Why it matters
People often hesitate to ask for assistance because they fail to appreciate how socially difficult it is for targets to decline a direct request. This establishes a systematic egocentric bias in social prediction and interpersonal coordination.
Limits
The abstract does not report participant counts, demographic characteristics, or specific request types tested. It does not provide statistical test parameters, leaving power and precision unverified from the abstract alone.
