Abstract
Considered as a personality assessment technique, graphology is defended by some but finds weak scientific base. Validation studies often suffer from methodological weaknesses. In this study, 145 participants wrote a text on a white sheet and answered the NEO PI-R, personality inventory. Having built a reliable grid of analysis of the handwriting, we correlate 13 graphological variables and 35 personality features taken from the five-factor model (FFM). After controlling sample effects, one correlation is compatible with graphology, one contradictory to it and most of them are unexpected. These results evoke type I errors and confirm the very low validity of graphology as a personality assessment technique. (C) 2008 Societe francaise de psychologie. Publie par Elsevier Masson SAS.
