I’m surprised because I saw that graphology is a pseudoscience. Probably my problem is that I confused graphology with graphanalysis. The second term makes references at analysis of letters of documents to identify the writer by comparison.
In the case of graphology , not only identify the writer, at the same time try to define his character, and his job performance.
During sometimes it’s considered available to predict characters and personalities but nowadays it’s considered in the same category that astrology or palmistry.
