Can financial success be measured by a person's fingers? Researchers from Higher School of Economics was able to demonstrate the link between the length of a person's fingers and its impact on the person's financial success. And this is not based on superstitious beliefs but on the magic of science.

According to researchers, the length of a person's fingers, in particular, the ratio of the length of the index finger and the ring finger can help determine a different number of skills and possible successes a person can have in life. The ratio of the fingers is known as 2D:4D ratio or the digit ratio reflects the level of perinatal testosterone the person as a fetus was exposed to during pregnancy.

The study, published in the journal Economics and Human Biology, is the first to examine the link between the digit ratio and a person's income. The study analyzed data collected from the Russia Longitudinal Monitoring Survey - Higher School of Economics (RLMS-HSE). A total of 1600 people, 700 men and 900 women, participated in the study with ages ranging from 25 to 60 years old. The participants were also asked about income and salaries.

The findings of the study show that there is a negative correlation between the 2D:4D ratio and income or salary in women. This means that women with high digit ratio, women having a longer index finger and shorter ring finger, will most likely have higher financial success. This finding is true regardless of taking into account factors affecting income like gender, educational level, age, job position, and job position's economic sector.

On the other hand, the result in men was opposite of that in women. Men who have low digit ratio, or men with a shorter index finger and longer ring finger, will most likely find higher financial income. The results for men and women are more or less the same except for a small number of the male respondents whose high level of education affects the person's financial success.

Previous studies have found that people with index and ring fingers of the same length are more likely to be faithful to their partners. Moreover, people who have longer ring finger are more likely to cheat around.
