Each lottery can yield one of two monetary outcomes (all positive outcomes, no losses). The range of magnitudes of the outcomes is {0,50}, the range of probabilities for each outcome {0,1}. Each lottery is displayed as a pie chart with the outcomes' probabilities represented by a shaded area of the pie and the magnitude displayed as a number in the respective area of the pie. Subjects are assumed to choose mostly the lottery with the higher subjective value.
