Do you have a radial loop fingerprint? In people who have radial loop fingerprints these are usually spotted on the index finger(s); in the field of hand reading it is a common beliew to associate radial loops with ‘people who do not go with the flow’ – refering to the fact that the radial loop represents sort of the opposite of the much more common ulnar loops. But what are the facts and how do they develop?

The latest research points out that a radial loops might have a connection with the Big Five personality dimension Extraverion (see picture below).

This article presents 10 facts about radial loops:

The family tree of fingerprint types

In 1943 Cummins & Midlo presented a work which became known as the Bible of fingerprints, titled: “Finger Prints, Palms and Soles”. The book is e.g. featured with a model named: ‘a family tree of finger print types’: see the picture above.

This ‘family tree’ presents an interesting perspective on how various types of fingerprints are related. Starting with the ‘concentric whorl’ (which sort of raises associations with various phenomena – such as: a solar system in the cosmos, or force fields in the atmosphere, hair streams on the human body, etc.), progressing via the ‘loop’, and ending with the ‘simple arch’ (which raises associations with more stable, inert phenomena).

At Amazon you can order a copy of ‘Finger prints, Palms and Soles’, or another fingerprint book (such as: ‘The Science of Fingerprints’ – a FBI production). For more details about the book, see: Google books & Ed Campbell’s article ‘Fingerprints & Palmar Dermatoglyphics.

New research links the ‘Moon whorl’ with autism! (On top of Down syndrome & schizophrenia)

In 1892, Sir Francis Galton published his highly influential book, ‘Finger Prints’ in which he described his classification system based on the number of triradii. On of the 3 most well-known fingerprint types is the ‘whorl’ (next to the ‘loop’ and ‘arch’), which is often found on the fingertips – but rarely found on the hypothenar (in palistry: ‘mount of Moon’)!

What was already known about the ‘hypothenar whorl’?

Quote from the article:

“While the classic palmistry literature describes that the ‘hypothenar whorl’ (a.k.a. ‘whorl on mount of Moon’) can be recognized as a sign for finding a ‘highly imaginative person’, various scientific studies have indicated that dermatoglyphic whorls on the mount of moon are linked with Down’s syndrome + a few other medical problems.”

NEW RESEARCH FINDING ON AUTISM!

Another quote from the article:

“A study on the hands of 30 people with autism (25 men, 5 women) revealed a surprizing high percentage of a specific (very rare) variant of the ‘hypothenar whorl’ – the ‘hypothenar composite whorl’.”

Some examples of the ‘hypothenar composite whorl’ are presented below.
3 Examples of a variant of the 'hypothenar whorl': the 'hypothenar composite whorl'.

In the perspective of the fact that in the science of fingerprints the ‘composite whorl’ is related to the ‘double loop’, it is interesting to notice here that the new finding relates to an earlier reported finding which pointed out that the hands of people with autism are often featured with a ‘double loop’ in the fingerprint of the pinky finger and the presence of 2 palmar loops below that 5th finger.

In cases you’re interested to learn more about the basics of fingerprint classification – the illustration below describes the 8 most common types of fingerprints (including: 2 ‘arch’ variants, 2 ‘loop’ variants, and 4 ‘whorl’ variants).

NOTICE: The ‘composite whorl’ whorl does not belong to the 8 basic fingerprint types (the name ‘double loop whorl’ in the picture below is traditionally described as a ‘double loop’).
