In my own case, with regard to investments, I call it the “you only live once and don’t get greedy” paradox. “The Ellsberg Paradox and Risk Aversion: An Anticipated Utility Approach .” International Economic Review, 28(1): 175–202. To capture this distinction, we adopt the multiple-priors utility model. Schmeidler, D. (1989): “Subjective Probability and Expected Utility without Additivity,” Econometrica 57: 571-587. I think it's completely consistent with expected-utility theory; it's standard risk-aversion in a vNM utility function. Subjective expected utility theory does not distinguish between attitudes toward uncertainty (ambiguous probabilities) and attitudes toward risk (unambiguous probabilities). The paradox was popularized by Daniel Ellsberg, although a version of it was noted considerably earlier b Se-'o~J, U., 1985, The Ellsberg paradox and risk aversion: An anticipated utility approach, International Eco[lomic Review While in some cases ambiguity aversion is an adaptive strategy, in many situations it leads to suboptimal decisions, as illustrated by the famous Ellsberg Paradox.

(1987) The Ellsberg paradox and risk aversion: An anticipated utility approach. The Ellsberg Paradox explains why we aim low and settle for the mediocre. A resolution of Ellsberg’s paradox is thereby provided, in which ambiguity aversion/seeking is “rational”, but the normative status of expected utility remains unassailed. This approach has been developed, with some success, in Epstein and Miao (2001).3 Further applications of our model are suggested by the related Selten, Reinhard, Karim Sadreih, and Klaus Abbink (1995) “Money Does Not Induce Risk Neutral Behavior, but Binary Lotteries Do Even Worse,” University of Bonn, Discussion Paper. Behavioral interventions for reducing ambiguity aversion should therefore be of substantial practical … The Ellsberg paradox is a paradox in decision theory and experimental economics in which people's choices violate the expected utility hypothesis. 62.
