The evolutionary stability of optimism, pessimism, and complete ignorance
Schipper, Burkhard - 2019
We provide an evolutionary foundation to evidence that in some situations humans maintain either optimistic or pessimistic attitudes towards uncertainty and are ignorant to relevant aspects of the environment. Players in strategic games face Knightian uncertainty about opponents' actions and...

Navigating ambiguity : imprecise probabilities and the updating of disease risk beliefs
Kerwin, Jason; Pandey, Divya - 2023
Probabilistic risk beliefs are key drivers of economic and health decisions, but people are not always certain about their beliefs. We study these "imprecise probabilities", also known as ambiguous beliefs. We show that imprecision is measurable separately from the levels of risk beliefs. People...
