Some of the interpretations are as follows:
Longer Ring Finger (Low 2D:4D Ratio): Having longer ring finger is often associated with people who are believed to be risk-takers, assertive, and have high self-esteem. Further, these people are believed to be competitive, ambitious, and outgoing.
Longer Index Finger (High 2D:4D Ratio): Having longer index finger is associated with people who are compassionate, emphatic, communicative, and nurturing. These individuals tend to avoid conflicts.
Equal Length: These individuals might display a combination of assertiveness and empathy, showing both competitive and cooperative behavior depending on the circumstances.

According to Science, the idea that finger lengths reveal significant personality characteristics comes from evolutionary biologist John Manning, now at Swansea University. His work has inspired over 1,400 studies in just over 20 years, linking finger ratios to personality, cognitive abilities, and disease risks. Some researchers have even used these ratios to speculate on the gender of ancient cave painters.
