Palmistry Criticism of palmistry due to its "lack of empirical evidence" for efficacy and accuracy has largely been dispelled. Simply stated, this is inaccurate. The advent of forensics and psychodiagnostic tools have brought palmistry into the forefront of the sciences. Ironically, handwriting analysis and fingerprinting have become widely used and accepted.
The study of the palm in relationship to individual psychology is called Psychodiagnostic Chirology. It's application, reasonably enough, has always been very limited to biological and organic disorders. The concept that the hand is a reliable source of information concerning deeper aspects of the individual has been slow to take traction in the behavioral sciences due to its association with charlatanry.
