Article Synopsis
- The study explores the relationship between second-to-fourth digit ratio (2D:4D) and various factors in firefighters, noting it didn't show a lower 2D:4D compared to local male controls, contradicting findings in other athletic populations.
- Lower 2D:4D was linked to lower service ranks, larger family sizes, and traits like left-handedness and sensation seeking, while showing no correlation with body-mass index or sporting performance.
- Additionally, novel findings suggested lower 2D:4D was associated with lower relationship satisfaction and smoking habits, emphasizing the need for further research on sex-hormonal effects on personality through both 2D:4D and absolute finger length.
