Abstract : The paper begins by pointing out the logical similarities between Expected Value (EV) theory and a number of theoretical formulations that have had successful careers in diverse areas of psychology. The notion is introduced that the failures of EV in contrast to the successes of the other theories may reside in the overprecision of the predictions and measurements in EV research as opposed to the rough predictions (e.g., more than, less than) and measurements (e.g., frequency response ratings on 7-point scales) in research deriving from the other theories. Then data are introduced from three experiments that imply that subjects are more tolerant of variance in their responses than EV experimenters are and that it, therefore, may be futile to try to expect highly precise predictions to be supported by the subjects' imprecise responses.
