In stated preference studies, consequentiality is expected to increase the validity of the results, where consequentiality means that respondents believe that the survey outcome will have real-life consequences. Sample size has received little attention so far in this literature. In an online single-bounded dichotomous choice field study dealing with underwater turbines, we provide information on sample size to a part of participants, where the information varies across participants. We find that sample size information has no effect on subjective consequentiality, which suggests that consequential single-bounded contingent valuation studies can still ensure incentive-compatible behavior when the benefits from voting becomes very small.
