The Decisions under Risk and Uncertainty Exploratory Course takes a broad view technological risk and how people respond to risks (for example by taking/accepting risks, avoiding risks, trusting others to deal with risks, analyzing risks scientifically, or designing technology more safely). Many important problems involve decision making under uncertainty—that is, choosing actions based on often imperfect observations, with unknown outcomes. Under conditions of certainty, accurate, measurable, and reliable information on which to base decisions is available. Some estimated probabilities are assigned to the outcomes and the decision making is done as if it is decision making under risk. Insurance 8.
