An experiment was conducted to investigate whether a graphologist (a handwriting analyst) could distinguish a normal person’s handwriting from that of a psychotic. A wellknown expert was given 10 files, each containing handwriting samples from a normal person and from a person diagnosed as psychotic, and asked to identify the psychotic’s handwriting. The graphologist made correct identifications in 6 of the 10 trials (data taken from Statistics in the Real World, by R. J. Larsen and d. f. Stroup [New York: Macmillan, 1976]). Does this indicate that the graphologist has an ability to distinguish the handwriting of psychotics? |
