5 Things a Man's Finger Length Says About Himby Tanya Lewis,
Staff Writer | February 21, 2015 07:39am ET
Men, take a look at your right hand. Is your index finger
shorter than your ring finger?
The ratio of these digits' lengths could hint at everything from
personality to intellect to physiology, anumber of studies
suggest.
Here are some of the things a man's finger length may say about
him. [Macho Man: 10 Wild Facts AboutHis Body]
Nice to women?
Men with short index fingers and long ring fingers tend to be
nicer toward women, according to a new study, to be published in

journal Personality and Individual Differences. The finding
could be a result of sex hormone exposure in the womb, scientists
say.
In the study, more than 155 individuals (78 men and 77 women)
filled out forms for every social interaction with a member of the
opposite sex lastingfive minutes or longer in a three-week period,
using a checklist of "agreeable" or "quarrelsome" behaviors. Men
with small digit-ratios (shorter indexfingers relative to ring
fingers) engaged in roughly a third more agreeable behaviors toward
women, and a third fewer quarrelsome ones, than men withlarge
digit-ratios, the reports showed.
Previous research has found that this "2D:4D" ratio the ratio of
the length of the second digit (the index finger) to that of the
fourth digit (the ringfinger) reveals the amount of male hormones,
mainly testosterone, a person is exposed to in the womb. The more
testosterone, the longer the ringfinger grows.
And studies have also linked this ratio to a host of other
qualities.
Penis size
A smaller 2D:4D ratio has been linked to a longer stretched
penis size, according to a 2011 study published in the Journal of
Andrology.
The study involved 144 volunteers ages 20 and older who were
undergoing urological surgery. While the men were anesthetized,
researchers measuredthe lengths of the men's fingers and penises
(both flaccid and stretched, which is linked to the erect penis
size).
The shorter the index finger relative to the ring finger, the
longer the stretched penis was likely a result of testosterone
exposure in the womb, theresearchers said,
Facial attractiveness
Men who have a shorter index finger than ring finger may also
have more handsome faces, suggests a 2011 study published in the
journal Proceedingsof the Royal Society B.
The amount of testosterone a baby is exposed to before birth can
affect how the individual's face develops, and how attractive that
face is, theresearchers said.
Previous research suggests that women prefer men with masculine,
cavemanlike faces. In other words, women are traditionally more
attracted to menwho have relatively short, scrunched upper faces,
as found in Will Smith and Brad Pitt.
SAT performance
Many of the finger-length correlations hold true in men only,
but some apply to women as well.
For children of both sexes, digit ratio was linked to scores on
the SAT college admission exam, a 2007 study published in the
British Journal ofPsychology found.
A team of scientists made photocopies of children's palms and
measured their digit ratios. Then the researches compared these
measurements with boys'and girls' performances on the SAT. Both
boys and girls whose index fingers were shorter than their ring
fingers scored higher, on average, in the mathsection than the
verbal. And girls with larger digit-ratios (ring fingers longer
than index fingers) scored better on the verbal portion of the test
than themath one, the study found.
Prostate cancer risk
But while having a short index finger relative to ring finger
has its advantages, they may come at a price: a higher risk of
prostate cancer, according to a2010 study published in the British
Journal of Cancer.
Researchers looked at the ratios of these finger lengths in
1,500 prostate cancer patients and 3,000 healthy men over a period
of 15 years. The scientistsasked the men to look at pictures of
hands and choose the one most similar to their own.
Men whose index fingers were the same length or longer than
their ring fingers were 33 percent less likely to be diagnosed with
prostate cancer duringthe study than men whose index fingers were
shorter, the study found.
The good news is, 33 percent is still a pretty small effect, so
men with smaller digit ratios shouldn't be too concerned, the
researchers said.

Gerald Playle Chico, CaliforniaYou are right. It doesn't
necessarily mean that, but it can. Although in thissituation, what
you said isn't really a refute towards the study. In this,
fingerlength and other aspects are correlated, but the article is
hinting at thecausation is the same for finger length ratio and
these other aspects. Ergo,recording one aspect, the finger length
ration, gives you an idea about otheraspects.Reply Like Edited

Zane Massey Star Command of Dank Memes at PhysioGainsthe
variable 'ring finger' has strong causation with the variable 'sex
hormoneexposure' which determined the rate of 'prostate cancer'.
just because avariable appears extraneous doesn't mean it's
irrelevant. Any purported formof science that neglects statistics,
is a pseudoscience my good sir.Reply Like March 19 at 10:04am
