ADVERTISEMENTS: When such conditions of uncertainty is there then … In particular, people underweight outcomes that are merely probable in comparison with outcomes that are obtained with certainty. framework to understand and guide decision-making under uncertainty in the context of the COVID-19 pandemic. Conditions under certainty are which the decision maker has full and needed information to make a decision. decision making problems, including reinforcement learning. Because of the importance of risk aversion in decision making under uncertainty, it is worthwhile to first take an ”historical” perspective about its development and to indicate how economists and decision scientists progres-sively have elaborated upon the tools and concepts we now use to analyze risky choices. What follows is a framework for determining the level of uncertainty surrounding strategic decisions and for tailoring strategy to that uncertainty.
