Abstract
Previous work has showed that people are averse to ambiguity and prefer to bet on known probabilities over unknown probabilities There is also evidence that ambiguity aversion is stronger in comparative contexts rather than in noncomparative contexts In the present paper we suggest that ambiguity aversion depends on people’s affective reactions and therefore the effect is more evident in comparative contexts because the comparison between the clear and ambiguous alternatives leads to more positive affective reactions toward the former rather than the latter The present study extends the previous findings while at the same time supporting the “comparative ignorance hypothesis”
