Three major conclusions may be drawn. First, the hypothesis that graphologists' predictions are more valid than those of psychologists when based on the same written material cannot be adopted. Second, the ability to predict behavior on the basis of written material seems to be allied with individual differences among the various evaluators. Third, since the psychologists' assessments were largely derived from the contents of the written material, and not its form, it may be deduced that the graphologists also (or only) based their assessments on the contents of the written material as did the psychologists (Fredrick, 1965). Whatever the case, this study cannot indicate the precise process by which the assessments were made by the graphologists, whether aware or not.
