Trained handwriting analysts are able to determine if a particular writer executed a specific piece of suspect writing. For best results, even that requires the voluntary submission of handwriting exemplars from the suspect. They are unable to determine anything at all about the psychology of the writer.

Graphology is a hoax, and a surprising number of graphologists are co-located with palm readers.
