In considering personality measurement in medical education, we are interested in measures t hat can be used for some purpose, such as selection , placement, counseling , or program design. If measures are to be useful in this sense , then we must be able to use them to predict something with greater accuracy than we would be able to achieve without them . There are at least two ways to go about improving the accuracy of one's predictions . The first is to improve the measures on the basis of which the predictions are made . Earlier in this conference Jackson ( ) , Stein ( ) , Fiske ( ), and Sechrest ( ) have already suggested ways in which this might be done . The second is to improve the way in which predictions are made on the basis of those measures which are available . It is this second possibility that I am going to discuss . The general logic of what I will say applies to any of the uses that might be made of personality measurements , but , because it is easier to discuss one procedure at a time, I will talk only about selection.
