BackgroundThe ratio of the index finger (2nd finger) to the ring finger (4th finger) (2D:4D) can give information about harmony between personality and career of individuals. The developing technology makes it difficult to choose a profession.AimThis study aims to contribute to the career choice of individuals by analyzing the relationship between the 2D:4D finger digit ratio and personality traits of individuals working in different professions (Educator, Worker, Housewife, Civil servant, Healthcare professional/ EWHCH).MethodThe participants were three hundred twenty-five individuals living in the province of Malatya. The SPSS 26.0 software was utilized in the data analysis. The p value of 0.05 was accepted as significance level in comparison testsResultsA statistically significant difference was determined between the participants, who had the 2D shorter than the 4D in right hand, in terms of professional groups (p<0.05). In healthcare workers, a low level (r=0.305) positive correlation was found between right hand 2D4D and both control (r=0.264) and curiosity and left hand 2D:4D, and a low level (r=0.255) negative correlation was found between Conscientiousness and right hand 2D:4D in housewives. There was a statistically significant difference between the groups (educator, worker, housewife, civil servant, healthcare professional) in terms of total score of the Five-Factor Personality Inventory (FFPI) and scores of extroversion, agreeableness, conscientiousness, neuroticism, and openness to experience subscales (p<0.05). a weak positive statistically significant correlation was detected between the healthcare professionals' score of Career Adapt-abilities Scale (CAAS) control subscale and the right-hand 2D:4D ratio. Conclusions: It is suggested to investigate the 2D:4D ratio over different professional groups. The present study is important since it gives information about personality and associates such information with the 2D:4D ratio.
