Finger length research: will the 2D:4D digit ratio become the new Chiromancy?
April 28, 2009
Chiromancy (cheiromancy), the notorious pseudoscience, has for two decades been creeping back into scientific favour. Is John T. Manning its new high priest?
The simplicity of the measure has inevitably launched a thousand research papers on hundreds of topics – including: heart attacks, breast cancer, running speed, football ability, sexual attraction, homosexuality, and schizophrenia.
|THE NEW CHIROMANCY
How to understand the new Chiromancy? Hold up your right hand, and put your palm towards you and keep your fingers together; then measure the lengths of the 2th finger (index finger) and 4th finger (ring finger) – measure each finger from the tip to the crease where it joins the palm: see the picture below. Dividing the length of the 2th finger by the length of the 4th finger gives what in the jargon is known as the 2D:4D ratio!!!
Folk mythology has long suggested that men with large hands or feet will be well endowed, but there seems to be biological truth in that adage, with biologists finding that the same gene family, the Hox genes, underpins the development of “apical appendages”.
Professor John T. Manning says:
“I believe that the pattern and nature of our decline in middle life and the disease which will eventually lead to our death, is dependent to a large extent on our experiences as a foetus.”
The handedness-expert Chris McManon (psychologist from the UK) wrote a critical review of John T. Mannings ‘digit ratio’ work. You can read the full review via:
