... Oh my god, interesting confirmation that 'hand shape' of various nations correlates with intelligence:

(This could become a 'tell-tale-story')

The new data CONFIRMS that there is a negative link between the 'hand index' the average IQ reported for most of these countries:

Sources for the IQ related data:

http://en.wikipedia.org/wiki/IQ_and_the_Wealth_of_Nations

Only the data for the relatively 'underdeveloped' Mauritius & India doesn't confirm the link; though when putten in the perspective of the data from Nigeria (which could also be described as an 'underdeveloped' country) ... it could make sense!!:

PS. thinking

NOTICE: The data from Jordania can not be used because the 'hand breadth' was measured with an alternative methode which includes the thumb.

... correcting the 'hand index' for the squarerooth of body length results in an even more impressive picture:

Which country has the largest hands in the world? - Page 2 Jp

Japan: average IQ = 105, average 'hand index/(sqrt body height)' = 3.33;
Which country has the largest hands in the world? - Page 2 Nl

Netherlands: average IQ = 102, average 'hand index/(sqrt body height)' = 3.41;
Which country has the largest hands in the world? - Page 2 Gb

UK: average IQ = 100, average 'hand index/(sqrt body height)' = 3.37;
Which country has the largest hands in the world? - Page 2 Cn

China: average IQ = 100, average 'hand index/(sqrt body height)' = 3.45;
Which country has the largest hands in the world? - Page 2 Us

USA: average IQ = 98; average 'hand index/(sqrt body height)' = 3.45;
Which country has the largest hands in the world? - Page 2 In

India: average IQ = 81, average 'hand index/(sqrt body height)' = ... females only: 3.25;
Which country has the largest hands in the world? - Page 2 Mu

Mauritius: average IQ = 81, average 'hand index/(sqrt body height)' = ??;
Which country has the largest hands in the world? - Page 2 Ng

Nigeria: average IQ = 67; average 'hand index/(sqrt body height)' = 3.70.

Only the relatively small Indian female sample results do not fit in this body-height-corrected 'hand-index' model; but the data clearly suggests:

The average 'hand index' does provide a clue for the average intelligence of nations!

(Though of course: we have to be aware of that cultural development should play a role in this matter as well!)

PS. I have also added the Nigerian + Indian data in the first post of this topic.

wow Martijn, I haven't digested all the info but at first reading this is an amazing discovery! well done and thanks for all your research! Thumb up

Thanks Lynn,

Yes, interesting stuff indeed... but just like in the '2d:4d digit ratio' (where any assessment should always be corrected for sexe & ethnicity)... we should be aware that any individual 'hand index' assessment should be corrected for: sexe, ethnicity + body length.

So, this might actually partly explain why so far the 'hand index' never really became a research object. It's a rather complex dimension of the hand (and you and I are aware than 'hand breadth' measurement is a rather complex measure on its own).

But I am exploring the possibility to combine 'hand index' with other related hand characteristics, such as the AtD-angle, and a new palmar dermatoglypic measure (that I will later describe with more details), plus some characteristics of the major palmar lines.

All these hand features appear to correlate with IQ (I am working on a growing database of statistics - which confirm the links).

Martijnji And Lynnji,
Namaste and Best regards.
I highly appreciate both of you for great efforts, data collection and thank you very much for healthy interaction only between you on Hand Index , I.Q. and their blending with formation as hand of nations. As an engineer I can say I.Q. graph is somewhat as a speed v/s fuel consumption graph. If hand index is decreased then I.Q. level is increased, after certain limit if it is decreased more I.Q. Level is also decreased. This notice is very critical “Hand breath is usually measured at the metacarpals, so the picture doesn't provide accurate information about that measurement.” It is not easy for palmists measure it at the metacarpals. If we put all people of nations in particular formats of hand it becomes funny to distinguish and to understand them.

Hello Mister U.B.,

What you write about how to measure the hand breadth is very true, and your other consideration might also be significant... if a hand is far too small, it might indicate an anatomical problem (and not a high IQ).

Thanks!

I have found another source which provides info anthropometic hand data which represents the average for Europeans & Americans (based on the average for males and females taken from from sources that represent very large populations), see page 8:
http://www.baua.de/de/Publikationen/AWE/Band3/AWE108e.pdf?__blob=publicationFile&v=6

I have listed the 'hand indices' resulting from those average hand measurements in the picture below!

PS. The details regarding the dermatoglyphics are explained here:

**Martijn (admin)** on Mon May 23, 2011 12:31 am

... and after studying the details in various populations, I can add that the averages for the world population appear to very close to the following data (after also considering data from China & Japan):

- The world 'hand index' (palm breadth vs. hand length) = close to 44.0
- The world 'palm index' (palm breadth vs. palm length) = close to 78.0
- The world 'finger index 1' (finger length vs. palm length) = close to 76.0
- The world 'finger index 2' (finger length vs. palm width) = close to 97.0

PS. Unfortunately there is no data available about the body height of the Chinese & Japanese samples, so I was not able to describe the hand characteristics of those samples in the perspective of their body height.

The content of this topic provided the basis for a brand new section at my website - presenting an introduction to the essence of finger length:

What can Finger Length reveal?

The article e.g. describes that when finger length is studied in the perspective of various dimensions of the palm, including length and bread... it turns out that people from India & Japan may have the longest fingers in the world!

(Though, so far based on a comparison between the finger lengths of people from Bangladesh, China, Colombia, India, Japan, Jordan, Mexico, Nigeria, UK, US and Vietnam)

Your thoughts & suggestions are welcome!

(Notice: the sub-sections are still under construction)

This Dutch website presents a anthropometry database for all regions around the world:
http://dined.io.tudelft.nl/en,international,6

(Hand length & hand breadt are included... EDIT: but based on the international studies that I have seen so far I think the hand-related numbers might not be reliable at all: e.g. Americans tend to have relatively wide palms - not narrow palms as suggested by this database!)

PS. Interesting, North Europe is not only the region with the tallest people, they also have the largest hands; the smallest 'hand index' (= relatively narrowest hands) is found in Latin America populations (+ North America & Japan)... and the largest 'hand index' (= relatively widest hands) is found in South China (West Africa, Eastern Europe & Australia).

PPS. Here's a list of data describing hand length versus stature (page 327: average hand length in various European populations is close to 11.5% of stature in both men and women - in western Europe the percentage is usually slightly smaller: close to11.3%).
