Individuals are often ambiguity-averse when choosing among purely
chance-based prospects (Ellsberg, 1961). However, they often prefer
apparently ambiguous ability-based prospects to
unambiguous chance-based prospects. According to the competence hypothesis
(Heath & Tversky, 1991), this pattern derives from favorable perceptions
of one’s competence. In most past tests of the competence hypothesis,
ambiguity is confounded with personal controllability and the source of the
ambiguity (e.g., chance vs. missing information). We unconfound these
factors in three experiments and find strong evidence for independent
effects of both ambiguity aversion and competence. In Experiment 1,
participants preferred an unambiguous chance-based option to an ambiguous
ability-based option when the ambiguity derived from chance rather than
uncertainty about one’s own ability. In Experiments 2 and 3, which used
different operationalizations of ambiguity in choice contexts with actual
consequences, participants attempted to avoid both ambiguity and chance
insofar as they could. These findings support and extend the competence
hypothesis by demonstrating ambiguity aversion independent of personal
controllability and source of ambiguity.
