After reading this article, you’ll never look at the length of the fingers on yourself or others quite the same way again!
Studies on the lengths and size ratios of the second digit (2D or index finger) and the fourth digit (4D or ring finger) on men and women have been going on since the 18th century. Why is that? Research has shown that the length of the 4D tends to be longer for people who were exposed to more testosterone in the womb. For the most part, the 4D tends to be the longer of the two fingers in males, but in females the digits tend to either be equal size or the 2D is slightly longer. Why is that? Some scientists believe that the more testosterone (male sex hormone) that was present in the womb will make the 4D longer, whereas more exposure to estrogen (female sex hormone) will make the 2D longer. Keeping up?
What does it mean for guys?
In men, the longer the 4D is above the 2D, the more you should exhibit certain characteristics, including:
• Greater fertility
• Larger chance of being a homo or bi-sexual
• The better you’ll be at sports
• The better you’ll be at playing music
• A more aggressive personality
Conversely, for men, the longer your 2D is above your 4D, the better your chances of having heart disease.
In women, the longer the 4D is above the 2D, the more you should exhibit certain characteristics, including:
• A more aggressive or assertive personality
• Greater predilection towards being homo or bi-sexual
• Better athletic skills
Conversely, for women, the longer your 2D is above your 4D, you’ll be more fertile and have a higher chance of getting breast cancer.
Basically what this tells us is that the more testosterone or androgen a baby is exposed to in the womb, the higher the incidence of the child displaying heightened male or female characteristics as an adult. But, these studies shouldn’t be seen as way to predict the current hormonal levels in men or women. Many men who suffer from low testosterone levels (a hormonal imbalance that can lead to erectile dysfunction) do so regardless of the size of their fingers.
Studies have also shown that higher amounts of testosterone in the womb may have a correlation to autism and Asperger’s syndrome. Another study linked a longer ring finger to be very beneficial to Wall Street traders. The study went so deep as to explain how the digit ratio can not only explain profitability, but also predict the length of their career in trading.
Although there has been more and more scientific research being done on the digit ratio, many still see the “science” to be a bit of a crude way of measuring hormonal exposure in the womb, predicting future behaviors or determining a person or couple’s ability to reproduce. Some scientists believe that the study of digit ratios speaks more to the truth of genetics rather than actual hormonal exposure or secondary sexual characteristics.
