A study from Japan found that in rats, the ratio of the second to fourth finger (2D:4D) can predict sexual activity and preference, suggesting a link between prenatal hormone exposure and adult sexual traits, with potential implications for understanding human behavior.
Scientists have found a potential link between psychopathic tendencies and finger length, specifically a lower 2D:4D ratio (a longer ring finger than index finger), which is influenced by prenatal hormone exposure. A study of 80 participants revealed that those with a lower 2D:4D ratio exhibited higher levels of psychopathic and antisocial traits. However, it's important to note that this ratio is not a definitive indicator of psychopathy, and it's also associated with better sports performance.
