How Do You Measure Up?
Increased verbal aggression Fq < 1
The shorter your index finger, the sharper your tongue: In both men and women, a lower Fq can predict more verbal sparring.
Improved athletic ability Fq < 1
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.
Improved sense of direction Fq < 1
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.
More physical aggression Fq < 1
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.
More risk taking Fq < 1
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.
Healthier knees Fq > 1
An index finger that’s shorter than the ring finger can be a sign of knee osteoarthritis risk, particularly in women, compared with people whose fingers are equal lengths, or who have a longer index finger.
Increased risk of oral cancer* Fq > 1
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.
Lower prostate cancer risk Fq > 1
Men with long index fingers and shorter ring fingers have a 33 percent reduced risk of prostate cancer. If they’re younger than 60, the risk is even less — 87 percent.
