To support our nonprofit science journalism, please make a tax-deductible gift today. If papers published in the past 6 months are right, a single number is enough to show whether people are likely to suffer a premature heart attack, land first authorship on published papers, become dependent on alcohol, or put on fat around the middle.

That magic number is the ratio between the lengths of the second and fourth fingers, known as the 2D:4D ratio.

It tends to be lower in men—meaning their fourth fingers tend to be longer than their second—than in women.

Researchers who believe in its predictive power say it reflects a fetus's exposure to testosterone and other hormones that guide development, including that of the brain. The idea that the lengths of human fingers reveal so much stems from the work of evolutionary biologist John Manning, now at Swansea University in the United Kingdom. But the field he inspired has ballooned beyond what he could have imagined.

More than papers in just over 20 years have linked the finger ratio to attributes such as personality, cognitive abilities, and sexual orientation as well as to risk of illnesses such as cardiovascular disease, cancer, and amyotrophic lateral sclerosis. Researchers have even tried to use ratios gleaned from stenciled handprints on cave walls to determine whether the artists behind ancient paintings were men or women.

But the notion has also riled plenty of critics, who argue that researchers who rely on the 2D:4D comparison have been seduced by a simplistic, faulty measure. Some doubters contend that the difference in ratios between the sexes is an illusion resulting from men's larger hands or that the measure itself is statistically problematic.

Other detractors argue the field is rife with irreproducible findings. It's "like a house of cards built on an unknown and uncertain base," says psychologist Martin Voracek of the University of Vienna, who compares the work on finger ratios to phrenology or physiognomy, the discredited ideas that people's head shape or facial features, respectively, reveal their personalities, character, and intelligence.

Yet as a simple, easy-to-measure quantity that promises insight into a hidden time of life—early fetal development—the finger ratio has enticed an entire generation of researchers while dismaying many others.

To behavioral neuroendocrinologist Kim Wallen of Emory University in Atlanta, a skeptic, the debate over the ratio and its significance "raises some fundamental issues about what we consider evidence. A German anatomist first reported in the s that finger proportions typically differ between the sexes, but the observation remained a curiosity until Manning hauled the ratio into the spotlight in He was collaborating with colleagues at a fertility clinic in Liverpool, U.

The disparity suggested a role for certain sex-related hormones. When he and colleagues measured finger ratios for patients at the clinic, lower ratios in men's right hands correlated with higher testosterone levels. John Manning and colleagues' study comparing the lengths of index 2D and ring 4D fingers found a subtle difference between the sexes, which they and others attributed to hormones affecting early fetal development.

By studying children and young adults from the Liverpool area, the scientists also discovered that the finger ratio discrepancy between the sexes held for kids as young as 2 years. That finding led the researchers to postulate that the difference arose before birth and reflected hormone levels in the womb.

The finger ratio, Manning explains, indicates the relative levels of testosterone and estrogen during early development. Manning, who has written two books and more than 60 papers on the ratio, didn't expect that his findings would have such an impact.

But the measure caught on. The idea that one number reveals so much about us is irresistible, notes statistical geneticist David Evans of the University of Queensland in Brisbane, Australia, who has studied the genetic basis of finger ratios. Researchers have used scanners, photocopiers, calipers, rulers, and even x-ray machines to assess finger length; in some studies the subjects measured themselves.

Scientists can swiftly and cheaply amass large amounts of data.

In addition, they are more aggressive and decisive and it is no problem for them to take a risk. The profession they usually have is: soldier, engineer, chess player and they are also successful in solving crosswords.

Whether they are calloused for instance, or cotton soft. The fingers in particular can give you further insights. A collaborative study conducted by Oxford and Northumbria researchers in the UK, found that differences in the lengths of certain fingers indicated whether a person tended to be more promiscuous or monogamous by nature.

The secret lies with the ring finger in comparison to the index. After studying North American and British men and women, they found that those who had longer ring than pointer fingers, in either sex, tended to be more promiscuous. While those who had a longer pointer than ring fingers tended to be more monogamous. A longer ring finger was associated with more testosterone exposure in the womb, the hormone responsible for the libido in both genders.

Men and women have differing levels of each sex hormone. Levels vary greatly among both genders. Some men have high testosterone for instance, as do some women, some men low testosterone, and so on.

Longer ring fingers were associated with a tendency toward more promiscuous relationships in one study. A McGill University study, including men, found that those with shorter index fingers in comparison to the ring finger were more agreeable and treated women nicer, than those with longer index fingers and shorter ring fingers.

The first case is called a small digit ratio.

These men, researchers assume, may be more willing to compromise, a trait necessary to healthy relationships. Debbie Moskowitz was the lead author in this study. A professor of psychology at the university, she said that men with a larger ring finger tended to have more solid relationships and were more likely to have children, due to their agreeable nature.

In this latest study, neuroscientists at The Norwegian University of Science and Technology NTNUfound that they could predict whether a person was a good athlete or if they were more of the anxious type, by examining index to ring finger ratios. Both men and women with longer ring fingers are better at spatial tasks, researchers determined. As such, they are better at physical jobs and athletics.

There are drawbacks however to those with a longer ring finger. These conditions are more prevalent in men. There are also advantages for those with a longer pointer finger. Low testosterone exposure in utero has been linked with better verbal memory.

A greater surge of prenatal testosterone can be an indicator of high levels of achievement in sports, as well as a mental toughness in athletics. In one study, college varsity athletes male and female were found to have shorter index fingers than other students.

In women, a more masculine digit ratio tends to predict a better sense of direction, backing up past research that found men tend to have better spatial cognition than women.

Men with shorter index fingers are more likely to pick fights. Women with the same hand shape are more likely to react with aggression after being provoked. Men who experience a higher surge of prenatal testosterone, and thus have longer ring fingers, tend to be risk takers. One example: The most successful financial traders tend to have the longest fourth fingers.

These behavior patterns seem to apply only to men. A high digit ratio — those with very little difference between the index and ring finger, or with a longer index finger — was found among men with oral cancer, compared with men with pre-cancerous oral lesions or no lesions, according to one all-male study.
