Evaluation of the Relationship Between Aggression and Digit Ratio Through a Cross‐Sectional Study Among Hitit University Students

The findings indicate that digit ratio does not exhibit marked sexual dimorphism; however, the expression of aggressive behavior appears to differ by sex. In females, shorter digit lengths (2D and 4D) are negatively associated with specific subdimensions of aggression, whereas in males, higher 2D:4D is positively correlated with anger and hostility. Although these results diverge from trends commonly reported in the literature and reached statistical significance, the low correlation coefficients warrant cautious interpretation.
