Summary
This study looks at whether the ratio of a person's index finger to ring finger (2D:4D)—a marker of prenatal hormone exposure—relates to mental toughness in amateur soccer players. Researchers measured finger lengths and surveyed 270 players about their mental resilience. The goal is to see if brain type, playing position, and psychological strength are connected.
