200 Ss judged 4 stimulus persons in 20 experimental conditions with varying amounts and categories of information given them. The greatest judging accuracy was obtained when total information input of different amounts and categories was greatest. Adding more input did not result in greater accuracy of judgment with all stimulus persons, however, and actually reduced accuracy for some stimulus persons. Further, considering the disproportionate amount of input increase necessary in order to yield small amounts of increased predictive accuracy, a question was raised concerning whether it is practically profitable to attempt to maximize predictive accuracy.
