Forensic Document Examination v. Graphology

Graphologists claim to be able to determine personality traits based on an examination of your handwriting. I personally have as much faith in this as I do the astrological forecasts in the newspaper...in other words, not much.

But I still read my horoscope occasionally. Why? Because it's fun! So if you want to have a graphologist examine your handwriting, go ahead. Enjoy yourself.

But asking a graphologist to do Forensic Document Examination is like asking an astrologer to help you land a rocket on the moon. Graphologists and Forensic Document Examiners look at some of the same things (handwriting) but using different methods and for different purposes.
