The representativeness heuristic (RH) proposes that people expect even a small sample to have similar characteristics to its parent population. One domain in which it appears to operate is the preference for combinations of numbers on lottery tickets: Most players seem to avoid very characteristic, “unrepresentative” combinations, for example, only containing very low numbers. Likewise, many players may avoid betting on a recently drawn combination because it would seem particularly improbable that the same numbers would be drawn a second time. We confirmed both of these tendencies in a lab experiment and corroborated their external validity in two field experiments. However, we only found a weak link between these two choices: The same people do not necessarily exhibit the two biases. In this sense, there is little consistent manifestation of the RH across different tasks at the individual level. Nevertheless, there are some links related to rationality across the two choices—people who are willing to forgo a monetary payment to get the preferred ticket in one task are also willing to do so in the other. We find such preferences to be related to the misperception of probabilities and the providing of intuitive, incorrect answers in the cognitive reflection test. Our findings suggest that there are few individual differences in terms of the propensity to be impacted by the RH—instead, such occurrences are determined by circumstances and pure chance.
