Palmistry’s finger analogue: will the 2D:4D digit ratio become the new Chiromancy?

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.


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!!!

Fingers of fate - 2D:4D ratio: how the measure the length of the index finger + ring finger?

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:

Britsh research points out that men whose ring fingers are longer than their index fingers run faster.

‘The World’s Fastest Hand’ – research points out: long ring finger relates to a fast sprint!

The 2008 olympics in Beijing pointed out that Jamaican sprinter Usain Bold has the world’s FASTEST hand… ever!

How come that Jamaican sprinters run so fast? John Manning’s new finger research points out that a long ring finger (low 2D:4D ratio) relates to a fast sprint – other research indicates: Jamaicans have the longest ring finger!

British researchers have found that finger length might be a key factor in Bold’s world records at both the 100m and 200m. For, Jamaicans are known for having a low ‘2D:4D digit ratio’.

The British ‘finger professor’ John T. Manning has recently presented new research which indicates that men who have a relatively long ring finger run faster! The research was done on 241 young male sprinters at a sports talent-spotting competition in Qatar.


Manning reported in his book ‘Digit Ratio’ (2002) that the average 2D:4D digit ratio in Jamaican people is among the lowest of the various populations in the world (a finding which was confirmed in a 2004 study). This might implicate that Usain Bolt’s digit ratio is actually not very low at all … in the perspective of the fact that he is a Jamaican man! The photo below illustrates that Asafa Powell, former world record holder & the second most famous sprinter from Jamaica, has the long ring finger as well!

While Leonid Stadnyk from Ukraïne (unofficially the largest man on earth) has the world’s LARGEST hand, Usain Bolt is the fastest man ever and so he is: the World’s fastest hand!

Sprinters from Jamaica have the long ring finger.
