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:

Whether they’re soft and manicured, strong and calloused, weathered and wrinkled—hands come in all shapes and sizes and can often say a lot about you. They can reveal the tattered fingernails of nervous nail biter, the orange fingers of a cheese puff lover, or the worn hands of a grandmother. And when you look even closer at the many lines and wrinkles, is it possible that your hands can reveal even more? Some people believe that clues to our basic selves can be found in the details of our hands. But do our hands really tell us anything of importance about who we really are? Is it possible that the numerous bumps and ridges unique to every hand hold some insight into our level of intelligence or into our love lives?

In an eternal quest for self-discovery, people have looked towards hand readers, among other mystics, to see if the lines in their hands really tell them something meaningful about themselves and their future. In current times, people turn to internet quizzes and online hand reading to make sense of the heart and life lines and the shape of their hands. Although these tests and quizes can be fun, when put to the test of empirical science, most of these claims and predictions cannot be verified. Furthermore, these uncorroborated predictions about personality traits and future events leave palm reading in the category of a pseudoscience.

Despite the inaccuracy of palmistry readings, however, there are aspects of the hands that have been studied empirically, including finger length. When looking at the palm of your hand, fingers straight together, you will likely notice a difference between your second (index) and fourth (ring) fingers. On average women have longer index fingers, compared to ring fingers while men have longer ring fingers compared to index fingers. This association between the two fingers, called the 2D:4D ratio, is related to levels of androgen exposure (a sex hormone higher in men) in the womb. That means that the amount of male hormones a fetus is exposed to determines this very specific detail of finger length in the hands. The precise mechanism by which androgen works is not entirely clear, but in general most theorists believe that increasing androgen exposure will masculinize a fetus. There is also some evidence suggesting that either too much or too little androgen can be feminizing to the fetus.

Because androgen exposure is related to sexual development and masculinization, researchers have begun to wonder if the 2D:4D ratio, as a marker of hormone exposure, may also predict other characteristics. Hormone exposure has been linked to things like general physical health, cognitive abilities, personality, job preferences, attractiveness, and sexual orientation. While the 2D:4D ratio may relate to these developmental characteristics, thus far the evidence supporting such a link is at best described as mixed. For example, there has been much attention dedicated to whether the 2D:4D ratio relates to sexual orientation. While there have been several studies in this area, some have shown no differences between heterosexual and homosexual men in their 2D:4D ratios (e.g., Williams et al., 2000), and others, like Lippa, have shown heterosexual men having lower 2D:4D ratios compared to homosexual men. Similarly with other characteristics like personality and attraction, the research findings have been fairly inconsistent.

Another aspect of the hands that have been conclusively studied are the ridges, the ones that cover the palms and fingers, the ones that make up our unique fingerprints. The study of these ridges is called dermatoglyphics. Similar to the finger length, these ridges are known to be established earlier in the embryonic development, while the fetus is still in the womb. Researchers have shown dermatoglyphic differences between non-deficient people and those with cognitive or genetic abnormalities, like schizophrenia, Down’s syndrome, and intellectual disability. For example, individuals diagnosed with schizophrenia show fewer ridges between two specific points under the second and third fingers [a-b ridge count] compared to non-schizophrenic controls (Bramon et al., 2005). These findings support the idea that changes in the prenatal environment can display its effects in multiple ways, including changes in cognitive development and ridges of the hands. However, the findings do not assume that all people with fewer ridges have cognitive deficiencies.

To summarize, we do know that specific details in our hands are affected by early hormonal exposure and other environmental influences in the womb. And we know that this early exposure also affects other aspects of our development. While it is intriguing to speculate further that details in our hands can predict aspects of our personality or behavior, these conjectures have not been empirically supported. It’s also likely that there are more direct measures of personality, intelligence, and behavioral traits rather than the hands. But even though you can’t currently rely on your hands to unlock all of your mysteries, one thing you can count on is more studies and discussion about them to come.

VoiceAmerica & Kenneth Lagerstrom present new radio show: Your life is in your hands!


[tweetmeme source=”handresearch” only_single=false] This week’s episode (June 1) of VoiceAmerica radioshow “Your Life is in Your Hands” was featured with the presence of UK hand analyst Lynn Seal, who talked with host Kenneth Lagerström about ‘lines of the hands’.

During the hour various aspects of the hand lines were discussed, including: the mystery of the ‘palmar flexion creases’, the prenatal development of the (major) hand lines in the early life of the embryo, line variations among ethnic populations, the differences between hand lines in the left and right hand, and how the hand lines can be used for different purposes in palmistry. Lynn explained very well that in time the hand lines can show significant changes; this simple fact might explain why the validity of ‘future predictions based on the hand lines’ are even disputed from within the palmistry community!

The podcast of the show is available at ‘Palmistry – The Lines of The Hand‘.

Let’s take a closer look on some basic characteristics of the hand lines. How can we learn to understand them properly?

In modern palm reading (cheirology) the hand lines are not used for predicting the future; contrary the hand lines are recognized as ‘energy flows’ reflecting process in the body and the brain which related the various aspects of an indvidual, including temperament, personality & and interpersonal functioning.
Palmistry: the major hand lines & palmar creases.


Contrary to what many believe, the development of the hand lines does not directly relate to the movements of the hands. For example, the three major hand lines (life line, heart line and hand line), start developing in the hand of the little embryo in the 2nd month of gestation – while the first hand movements do not occure before the 2nd half of the third month.

Another indication is provided by the fact that usually the ‘passive’ hand (= left hand for righthanded people) shows more hand lines then the ‘active hand’ (= right hand for righthanded people). And often the hands of people who are active in jobs that require a lot of manual work, show less palmar lines than those who are active in jobs that are not featured with the use of the hands (such as social work).

After about 7 weeks the life line starts developing in the hand of the embryo.

Despite the fact that many palmists around the world – especially in Asia – still claim that the lines in the palm or our hands reveal information about our future, the truth is that within the global palm reading community there appears to be a growing number of debaters who actually question the validity of this claim.

While traditional palmistry has merely been a matter of using the hand as an occult ‘tool’ – focussed on making (future) ‘prediction’; in the 20th century modern palm reading became more focussed on the issue of understanding human nature, by studying the psychological- & spiritual life of individuals.

The most frequently asked question is probably: “what do my hand lines reveal?” Interestinly, the answer might actually depend on the person who is faced with this question! For example, a traditional palmist might point to your future, a modern palm reader might point of your brain, and a scientific hand analyst … might point to your genes!

[tweetmeme source=”handresearch” only_single=false] Earlier this month actress Megan Fox claimed to have Obsessive Compulsive Disorder (OCD). Psychodiagnostic Chirology describes some typical hand characteristics that have been associated with this disorder. Do Megan’s hands confirm that she has OCD?

In the in the June 2010 issue of Allure magazine (not yet published) Megan Fox describes that she suffers from Obsessive Compulsive Disorder and has problems with everyday scenarios.

Megan explained, “This is a sickness, I have an illness. Every time someone uses a bathroom and they flush, all the bacteria is shot into the air.”

Ms. Fox also brings her own silverware wherever she goes. “Putting my mouth where a million other mouths have been, just knowing all the bacteria that you carry in your mouth? Ucch!”

Fox also claimed that she can cope without food, Megan also insisted she wouldn’t mind going for lengthy periods of time without any human contact as she prefers her own company.

She said: “I could go days, weeks, without talking to another human being. I hate receiving compliments; I hate being told I’m talented or people think I’m going to be a movie star. I always feel that it’s forced and fake.”


PDC analyst Arnold Holtzman has described in his book about Psychodiagnostic Chirology a list of 7 hand characteristics that appear to be associated with Obsessive Compulsive Disorder. Let’s see if Megan Fox’s hand meet those characteristics:

NOTIFICATION: Holtzman described in this book very explicitly: “Each of the (7) features noted below must be in evidence for a diagnosis of obsessive-compulsive personality disorder to be valid.”

Example of a thumb with an 'OCD angle'.

>> 7 Hand characteristics of Obsessive Compulsive Disorder:

• 1 Hard & inflexible hands and the palms are never soft, nor dysplastic – No, Megan appears to have flexible hands;

• 2 Pronounced knuckles – No, Megan has smooth fingers;

• 3 Nail phalanges of ring- + middle finger are spatulate in shape & always heavier than the base phalanges – Yes, but Megan has only spatulate fingernails; but her ‘famous’ thumb appears to be significant here, for obviously the nail phalange of her thumb is ‘heavy’ (it’s the condition named: brachydactyly type d);

• 4 Pronounced muscular tonus, including a sharp ‘thumb angle’ (see picture below) – Yes, Megan has the typical thumb angle;

• 5 Back of the hands: coarse skin with a masculine texture – No, obviously Megan doesn’t have a masculine texture;

• 6 Ring finger is longer than index finger – Yes, Megan’s ring finger is a bit longer than her index finger (though her finger length appears to be within the range of ‘normal’: see picture below);

• 7 Palm is square shaped, and never long and narrow – Yes, Megan’s palm appears to be a bit square shaped.

Megan seeking for obsessive attion?


Megan Fox appears to have some of the typical hand characteristics that are associated with Obsessive Compulsive Disorder, but no more that 4 out of 7 of the OCD associated hand characteristics – which is formally not high enough to confirm Megan’s problem.

What do you think? Does Megan Fox have ODC?

Barack Obama's hands: the hand of power!

Where does the charismatic strength of Barack Obama come from. Hand analysis and hand language experts provide an interesting answer from his hands only!

British palmist Palmist Lori Reid & U.S. hand analyst Ronelle Coburn provide some tell-tale lines that reveal Obama’s personality and his complex background.

Both are authors of hand reading books, and they described their interpretations of: Barack Obama’s hand shape (I), the length and width of his fingers (II), his palm (III), and his hand lines (IV).

Another interesting feature of Barack Obama’s hands concern his ‘low 2D:4D digit ratio‘: the ratio combination of his a bit too short index finger, and a rather long ring finger. The low ‘finger ratio’ has been associated by the ‘finger professor’ John T. Manning with a rich number of typical male characteristics, such as: sensation seeking, aggression & assertiveness, and autism.

By the way, this hand characteristic that is seen in quite of lot of hands of powerfull men – including dictators like North Korean dictator Kim Jong Il and Myanmar dictator Than Shwe. Barack Obama’s hand is for sure a hand of power!

Palmist Lori Reid says:

“Mr Obama’s hand (left) has extraordinarily long fingers and a long palm. This hand shape fits into a category known as The Water Hand and is a common feature of artists, writers and thinkers.”

Hand analyst Ronelle Coburn says:

“The most striking thing about Obama’s hands is their narrow width and extreme length. The overall shape of someone’s hands indicates the foundation of their personality and Obama’s is a combination of the elements water and air indicating a very thoughtful, and even visionary approach to relationships.”
