Finger length may directly relate to risky behavior in men

New studies show a link in men between finger length and testosterone, risk-taking, and financial success. The study at Concordia University, found in Personality and Individual Differences, explains the length between the index (second) and ring (fourth) fingers may be due to prenatal testosterone levels.

Researchers believe these alpha males may be more likely to take risks in relationships and when investing.

Past studies have shown links between testosterone levels in men and potentially risky behavior, sometimes linked to financial success. This study evaluated testosterone levels in men, specifically prenatal testosterone. Discoveries were made about risk-taking behaviors in financial, social, and personal situations.

As women are usually more attracted to men who are healthy and wealthy, many men engage in potentially risky behavior to be more attractive. Interesting findings in this study show a link between these behaviors and testosterone exposure when in the womb — more testosterone means higher chances of risky behavior.

For the study, researchers used a survey to evaluate 413 students , both male and female. The study compared index finger length with other finger length. Researchers discovered people with lower ratios were more likely to be risk-takers. Additionally, researchers compared index finger length to ring finger length and noticed similar results.

These findings were only discovered in men. Researchers believe women usually avoid risky behavior to appear more attractive, while men show opposite behavior.
