"Hand Structure and Psychopathy: What Your Fingers Can Reveal"

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.
