Type: article

Abstract: This study explores the correlation between the 2:4 Digit Ratio and trait Neuroticism alongside gender expression. In all, 260 adults indicated the 2:4 Digit Ratio on their left hand and completed a work-related personality measure. As established in many studies, sex differences were present in the ratio. We also identified significant differences associated with masculine-feminine ratings and trait Adjustment (low Neuroticism). Implications and limitations are discussed.
