When offered an opportunity to win $1 on every ''win'' trial in which
they drew a red jelly bean, subjects frequently elected to draw from a
bowl that contained a greater absolute number, but a smaller proporti
on, of red beans (e.g., 7 in 100) than from a bowl with fewer red bean
s but better odds (e.g., 1 in 10). Subjects reported that although the
y knew, the probabilities were against them, they felt they had a bett
er chance when there were more red beans. Similar, but less extreme re
sults were obtained on ''lose'' trials, where drawing a red bean meant
losing $ 1. These results were predicted from the concretive and expe
riential principles of cognitive-experiential self-theory. Nonoptimal
choices in the laboratory were significantly correlated with heuristic
responses to relevant vignettes and with self-reported gambling in re
al life.
