"Psychopathic Tendencies Revealed by Surprising Physical Trait, Study Finds"

A study in Canada found that individuals with clinically diagnosed psychiatric issues, particularly those with "Dark Triad" traits such as psychopathy, are more likely to have a shorter index finger and longer ring finger, indicating a lower 2D:4D ratio. This ratio is associated with prenatal exposure to higher testosterone and lower estrogen, but the lead author warns against interpreting finger length as a person's irrevocable fate.

"Hand Structure and Psychopathic Tendencies: What Your Fingers Reveal"

A study from the Centre de Recherche Charles-Le Moyne in Quebec suggests that individuals with a longer ring finger than index finger are more likely to have psychopathic tendencies, indicating a potential biological root for psychopathy. The research, which involved 80 participants, found a clear link between a lower 2D:4D finger ratio and antisocial traits, as well as higher scores on Dark Triad personality tests. Lead researcher Serge Brand explained that these results are associated with increased exposure to testosterone and decreased exposure to estrogen in the womb, but emphasized that finger length ratio is not an absolute indicator of psychopathy.

"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.
