Validation of Graphoanalysis by “Global” or “Holistic” Method

Abstract

Graphoanalysis is the most systematically developed and best researched of all methods of handwriting analysis (genetically called graphology). This is a projective expressive movement that is neither better nor more poorly validated than most projective techniques as a means of personality assessment, which is inadequate because their subjectivity makes statistical study difficult. With all projective techniques "sign" or trait validation has been minimal, and the best validation has come from "global" or "holistic" methods. The present study presents a paradigm for the latter type of approach to handwriting analysis, using a matching technique with probabilities of 1/5, wherein five subjects were matched by people who knew them to one of five blind Graphoanalyses of the subjects' writing. This design is herein replicated five times, with total data significantly different from chance expectation (p less than .001), supporting the hypothesis that it is possible to evaluate personality through analysis of handwriting.
