Summary:An experimental study of the efficiency of human information processing is based on the Bayesian model for simple hypothesis testing with fixed binomial sampling. Each of 60 subjects is analyzed with separate ANOVAs focusing on two efficiency variables. Sample size and critical value are also analyzed. Subjects show very different utilization of the independent variables diagnosticity, prior probability and loss, both for their choices and their efficiency of the choices. Giving a part of the experiment as a group test generates similar efficiency results. Efficiency does not seem to be related to intelligence. Final comment connects the experiment with the lens model. (Author/LH)
