Many of us have studied our hands and noticed whether our index or ring finger is longer. For most, this is a purely aesthetic concern, or the vague memory of something we heard somewhere about what this difference means. It turns out, whether you have a longer index or ring finger means a lot.
Research suggests that having a longer ring finger compared to index finger reflects greater exposure to male hormones during an individual’s time in their mother’s womb. There are differences between and within sexes in finger lengths associated with relatively more masculine versus feminine development. In fact, prenatal hormone exposure may provide important insights into the sources of sex differences in a variety of health conditions in adults.
Of course, we cannot measure prenatal hormone exposure in people. But we can use relative length of the second and fourth digits (that is, the index and ring fingers) as an indirect indication.
Two studies presented at the Alzheimer’s Association International Conference last week present new data about the link between relative digit length and whether individuals develop cognitive impairment or dementia when they are older.
Gatz and her colleagues used USC’s Understanding America Study, a probability-based online panel of more than 8,000 American households, to compare those who reported relatively longer index finger to those who reported relatively longer ring finger. Panel participants previously completed three web-based cognitive tests—number series, picture vocabulary, and verbal analogies.
The team reported a statistically significant pattern for women, especially on number series and verbal analogies. At younger ages, women with relatively longer index fingers scored higher than women with relatively longer ring fingers, consistent with verbal abilities being better in girls than boys. Also in women with relatively longer index fingers, those who were older scored lower than those who were younger, consistent with age-related changes in cognition. However, at the oldest ages, women with relatively longer ring fingers scored the same or higher than women with relatively longer index fingers, and older women scored just as well as younger women. There were no statistically significant differences for men.
Pike and his colleagues recruited older adults from community adult care centers and assisted living facilities. Those with a positive history of dementia or significant memory impairment comprised the ‘dementia’ group; all other subjects were classified as ‘non-dementia’. Research assistants used a scanner to make an image of the participants’ hands. Then they measured lengths of second (2D) and fourth digits (4D) using a caliper. These values were used to calculate a ratio of 2D:4D. All measurements were made by an investigator who was blind to who was designated as dementia status.
Women with dementia had a significantly more feminine (higher) 2D:4D compared to women without dementia, suggesting a female pattern of early development may predispose to dementia. The difference was not statistically significant for men.

The results of these two studies suggest that prenatal male hormone exposure may help to preserve cognition in older women, potentially making them less vulnerable to Alzheimer’s disease. These findings contribute to understanding possible bases of sex differences in dementia risk. Currently the best recommendations for maintaining healthy cognition at older ages include a healthy lifestyle such as regular physical activity and good cardiovascular health.

People with higher digit ratios tend to score higher for the personality trait of agreeableness (ie they're just nicer people). Men with higher ratios do better in exams but are more likely to have paranormal and superstitious beliefs.
The length of your fingers can indicate dominant traits, intelligence, and hidden desires. A shorter index finger compared to the ring finger suggests higher prenatal hormone exposure, indicating exceptional leadership skills, resourcefulness, intelligence, goal orientation, and analytical temperament.
Research suggests that having a longer ring finger compared to index finger reflects greater exposure to male hormones during an individual's time in their mother's womb. There are differences between and within sexes in finger lengths associated with relatively more masculine versus feminine development.
It is believed that having the index finger bigger than the thumb can mean that you are stubborn. However, it can help you achieve great success in life. The expert told us that you may be someone who doesn't give up easily under any circ*mstances.
The ratio of index finger to ring finger length was significantly different between the sexes on both sides of the hand (p<0.001). In terms of the right hand, the threshold value was 0.9666 for men and 0.9952 for females, while in terms of the left hand, the values were 0.9638 and 0.9920, respectively.
Straight finger shapes indicate honesty and a strong aversion to lies, while pointed finger shapes suggest being an ardent dreamer who believes in love. Knuckled finger shapes indicate valuing truth and integrity, being calm and open-minded, but also having intense anger.
For the visual test, the results were unambiguous. "The longer the ring finger compared to the index -- that is, the greater the exposure to testosterone -- the more attractive the face was rated," she said by phone. "We also found that attractiveness and symmetry in the face are highly correlated."
It is believed that the shape of your hands can reveal insights into your personality traits. For example, people with short fingers and small palms are often described as honest, conscientious, and traditional, while people with long fingers and long palms are often described as creative and imaginative.
The size of a man's hand size can, however, reveal a lot about his biology. Studies have shown that whether a man has small hands, big hands, or average hands, male hand size gives away a ton of information about everything from a man's athletic ability to his sex life and even his penis size.
Women whose forefinger was shorter than their ring finger were more likely to describe themselves as 'assertive and competitive' than women whose forefinger was longer than their ring finger. This finding could reflect the simultaneous effect of prenatal sex hormones on body and brain.
Research papers suggest the “best” length for a middle finger is 9cm, not only does it indicate righteousness, but that person would also continue to progress in life. However, if the person's middle finger is longer than 9cm, his or her life is more likely to be riddled with dangers, risks, and failures.
In human hands, the relative lengths of the second and fourth fingers differ between males and females. In males, the second digit (2D, or index finger) is usually shorter than the fourth digit (4D, or ring finger), whereas in females the index finger is generally equal to or longer than the ring finger (Fig.
A Morton's toe otherwise called Morton's foot or Greek foot or Royal toe is characterized by a longer second toe. This is because the first metatarsal, behind the big toe, is short compared to the second metatarsal, next to it.
The second metatarsal, the long bone in the foot connected to the second toe, is the longest bone in the foot. It's natural for some people that the second toe protrudes out further than the great toe. This condition is genetically inherited and occurs in three to fifteen percent of the population.
The Celtic foot is believed to be a variation of the Greek foot with toes of different lengths that don't follow a strict descending order. A Celtic foot may have third or fourth toes that are about the same length as the big toe! Or the third, fourth, and fifth toes have a grouping of the same size.
The second digit is typically shorter in both males and females, while the difference in length of the two digits is greater in males than females. The normal range of 2D: 4D ratios among males and females have been reported to be 0.947±0.029 and 0.965±0.026, respectively [13].
Some of the variation in ratios is due to genetics. So a significantly longer ring finger for instance could be partly due to the DNA you get from your biological parents. Your digit ratio may also be related to the relative levels of testosterone and estrogen you were exposed to in the womb.
Finger length ratio (2D:4D) is a sexually dimorphic trait. Men have relatively shorter second digits (index fingers) than fourth digits (ring fingers). Smaller, more masculine, digit ratios are thought to be associated with either higher prenatal testosterone levels or greater sensitivity to androgens, or both.
Both males and females tend toward longer ring than index fingers. The 2D:4D ratios for men range from 0.92 to 0.98 while those for females are slightly larger, ranging from 0.92 to 1.00.
