As with any thoughtfully-executed experimental design, our procedure was not without limitation. All subjects completed the survey in the same room and at the same time as multiple subjects; the anxiety caused by wanting to finish before (or at the same time as) other subjects may have interrupted the cognitive processes used to make the decision in each scenario. The length of the survey may also have caused subjects to tire and pay less attention to the questions towards the end. Also, even though we offered a forced-choice survey, some subjects felt it necessary to provide written justification for some of their selected answers. Justification for a decision has been shown to weaken the framing effect (Kim, et al. 2005), and those subjects providing justification may have confounded the study. In addition, because the degree to which a scenario offered a low or a high payoff was determined by the experimenters and not subjected to measures of validity, the results of the experiment may not be as legitimate as possible.
