Palmistry: A Scientific Exploration of an Ancient Practice
Studies have investigated the relationship between palmistry and personality traits, such as extraversion, neuroticism, and conscientiousness. One study found that individuals with a "long" life line (a line extending from the base of the thumb to the edge of the palm) tended to exhibit higher levels of conscientiousness and agreeableness (Jiang et al., 2018). Another study reported a correlation between the presence of a "simian crease" (a single palmar crease) and increased creativity (Kalmann et al., 2017).
