A Study of Finger Length Relation ( Ring finger & little finger i . e . 4 D 5 D ) with Human Personality

Several studies in the past have demonstrated a strong correlation of finger lengths ratio and human personality. This current prospective study attempts to correlate the finger length ratio of the 4 to 5 finger in males and females with the human personality traits --Psychoticism, Neuroticism & Extraversion using EPQ (Eysenck Personality Questionnaire). The hypothesis in this study is that males and females having the tip of the little fingers below the distal finger mark on the adjacent ring fingers in both their outstretched hands (arbitrarily named Group C) will have higher Neuroticism scores (i.e. they will be more anxious, worried, moody, and unstable), compared to the males and females who have the tip of the little fingers above the distal finger mark on the adjacent ring fingers in both their outstretched hands (arbitrarily named Group A). The results of this study shows that Group C females have a significantly higher Neuroticism and Psychoticism scores compared to Group A females. Similarly in case of males the results show that Group C males have a significantly higher Neuroticism and Extraversion scores compared to Group A males. So, there is a genetically predetermined physical marker i.e. whether the tips of the little fingers are above or below the distal finger mark on the adjacent ring fingers in both hands that determines the characteristic personality traits of a person.
