Abstract [en]

Two types of measures of probabilistic uncertainty are introduced and investigated. Dispersion measures report how diffused the agent's second-order probability distribution is over the range of first-order probabilities. Robustness measures reflect the extent to which the agent's assessment of the prior (objective) probability of an event is perturbed by information about whether or not the event actually took place. The properties of both types of measures are investigated. The most obvious type of robustness measure is shown to coincide with one of the major candidates for a dispersion measure, the mean square deviation measure.
