Decoding the language of the hand: how to find 36 conditions with 56 major hand signs!

How to decode
the language of the hand
for a specific condition?

The contents in the table above point out for each condition which hand sign combinations bare the highest significance - see especially the hand signs labeled with a golden square. You can start using the contents of the table by first choosing a condition in order to find a combination involving two hand signs that bare high significance for that specific condition; the table allows you to rule out the possibility that the hand sign combination choice also bares significance for other conditions!

The continuation of this article below presents a quick summary of the most signficant hand signs for every individual condition, often featured with a reference to related materials (including phantom pictures & other detailed guidelines).

NOTICE: The left column summarizes all 56 hand signs + a summary of the most significant hand signs is presented below for each of the 36 conditions!





TIP: In order to find highly significant hand sign combinations for a specific condition, combinations involving both the palm and the fingers is the 1st strategic step to strive for to make sure that various parts of the hand get included; additionally, combinations involving multiple hand levels is the 2nd strategic step. For far most conditions both steps are required to make sure that an accurate assessment is made; more details on the significance of this fundamental issue are outlined in the section
Multi-Perspective Hand Reading.

- Hand level 3: low hand index.

- Hand level 5: high finger length to palm breadth ratio, tendency towards long distal phalanges + short proximal phalanges.

- Hand level 8: combinations involving the following dermatoglyphic features bare potential to become significant: large palmar triradial area, many non-radial small/arch related patterns, ulnar (tented) arch combined with ulnar loops, pocket loop on the middle finger.

- Hand level 9: combinations involving the following crease features bare potential to become significant: long proximal crease & distal crease combined, well developed mid-axis line with tendency to be located towards ulnar side.

Phantom pictures for the hand in the Big Five personality dimension Conscientiousness.

[38]: N- = low conscientiousness (= casual):

IMPORTANT: The effect-size of individual hand signs associated with the Big Five personality dimensions is relatively small, and always much weaker than the largest effect-sizes seen in syndromes & disorders. This suggests that at best only a combination of hand features bares the potential to produce high significance, and this might even be typical for any aspect of personality!

Summary of the most significant hand signs in Conscientiousness low scorers:

- Hand level 3: high hand index.

- Hand level 5: low finger length to palm breadth ratio, tendency towards long proximal phalanges + short distal phalanges.

- Hand level 8: combinations involving the following dermatoglyphic features bare potential to become significant: small palmar triradial area, radial whorl-related fingerprint patterns with both triradii extralimital, large amount whorls and/or extralimital patterns, whorl- & arch combinations in 1 or both hands, unusual distribution of arch-related patterns.

- Hand level 9: combinations involving the following crease features bare potential to become significant: short proximal crease & distal crease combined, weak developed mid-axis line with tendency to be located towards radial side.
