Three studies, conducted on a total of 302 college student participants, used an "optimal stopping" paradigm, in which participants viewed a series of options (in Studies I and 2, the options determined how their time would he spent in the latter part of the study: in Study 3, the options represented qualities of a hypothetical potential housemate). Participants had to choose or reject each in turn. I show consistent support for two hypothesis: Decision-makers continue to view and review options in order to gain a better understanding of the distribution of potential options, and decision-makers who have a better understanding of the option space end up with higher-quality decisions, using objective, subjective, and revealed-preference measures of quality. These results were consistent for multi-attribute decisions, single-attribute decisions. hypothetical decisions, and non-hypothetical decisions using both within-subjects and between-subjects designs. Individual differences among decision-makers did not show any consistent individual difference results, though decision-makers higher in numeracy appear to make better use of the cues available to them. In sum, decision-making appears to he aided by understanding the distribution of options, suggesting that it is occasionally wise to delay or "procrastinate" choice in order to gain an understanding of potential options when choosing. === Committee in charge: Sara Hodges, Chairperson, Psychology; Sanjay Srivastava, Member, Psychology; Paul Slovic, Member, Psychology; Lynn Kahle, Outside Member, Marketing
