Hand Diagnostics & Psychology:

Charlotte Wolff, intelligence, feeble minded people, syndactyly & abnormal creases!

A few decades ago Charlotte Wolff¹ reported dermatoglyphics can provide some clues related to the intelligence of a subject, see table D-1.

Only a few years ago some Spanish researchers reported some supportive evidence from the hands of feeble minded children. In the hands of 62 feeble minded children these Spanish researchers observed a high number of arches and radial loops, and a high number of abnormal creases was reported as well. By the way, Wolff described more specific a relationship between low IQ and 'an arch pattern on the thumb' combined with 'abnormal creases'.

Table D-1: Observations by Wolff on feeble minded people (N = 412, IQ<70)
and a control group (N = 150, IQ>70).¹

-	- Feeble minded	- Control group
- DIMENSION 1 - dermatoglyphics:	-	-
- Arch pattern on the thumb	- 8.1 %	- 6.0 %
- Arch patterns on fingertips	- 22.0 %	- 20.0 %
- Whorl or loop on the thenar or hypothenar	- 25.6 %	- 15.0 %
- DIMENSION 2 - morphology:	-	-
- Small thumb	- 31.1 %	- 3.0 %
- Short fifth finger	- 26.3 %	- 10.0 %
- Missing crease on the on the fifth finger	- 2.2 %	- 0.0 %
- Syndactyly (failure of finger differentiation)	- 1.0 %	- 0.0 %
- Underdeveloped finger nails	- 33.3 %	- 2.0 %
- Concave primitive fingernagels	- 9.8 %	- 0.0 %
- DIMENSION 3 - creases:	-	-
- Simian crease	- 19.9 %	- 2.0 %
- Missing vertical palmar crease	- 27.0 %	- 5.0 %
- Chaotic palmar creases	- 7.7 %	- 0.0 %
- Short head line	- 9.6 %	- 1.0 %
- Irregular developed head line	- 54.7 %	- 19.0 %
- Short heart line	- 4.1 %	- 0.0 %
- Irregular developed heart line	- 32.3 %	- 27.0 %
