The ratio between second and fourth finger (2D:4D) is sexually dimorphic; it is lower in men than in women. Studies using broad personality domains yielded correlations of 2D:4D with neuroticism, extraversion or agreeableness, but the obtained results have been inconsistent. We correlated 2D:4D of 184 women and 101 men with their scores in Cattell's 16 Personality Factor (16PF) Questionnaire. We found women with a higher (more ‘feminine’) right hand 2D:4D to score lower in emotional stability…

The 2D:4D-Ratio and Neuroticism Revisited: Empirical Evidence from Germany and China
Prenatal exposure to sex steroids appears to influence the personality factor Neuroticism in females specifically, and this finding potentially has implications for mental health, as neuroticism has been shown to be a risk factor for various forms of psychopathology.
Domain Specific Relationships of 2D:4D Digit Ratio in Risk Perception and Risk Behavior
It is revealed that 2D:4D shows not only gender differences but also individual differences in personality and risk-taking behavior, particularly in the financial domain activities of investing and gambling.
The Relation of Digit Ratio (2D:4D) and Absolute Finger Length to Pavlovian Temperament Dimensions
Both prenatal and postnatal androgen action may contribute to small amounts of individual differences in Pavlovian temperament dimensions in men but apparently not in women.
Emotional stability is related to 2D:4D and social desirability in women: Possible implications on subjective well-being and psychopathology
A positive association is found between 2D:4D and emotional stability, as well as with its subdimensions emotion control and impulse control, but no association was found with the other four dimensions.
Second to Fourth Digit Ratio and the Big Five Aspects and the Externalizing Spectrum of Psychopathology
The ratio of one’s second to fourth finger is a marker of prenatal testosterone exposure. The current study seeks to examine this phenomenon as it relates to the Big Five Aspects of personality and
Finger Length Ratio (2D:4D) in Left- and Right-Handed Males
The result can be interpreted as proof that left-handers were subjected to higher levels of testosterone in utero, and the value of Dr–l in left- handers was significantly lower than Dr-l in right-hander.
Differences in the 2nd to 4th digit length ratio in humans reflect shifts along the common allometric line
It is demonstrated that the sexes do not greatly differ in the scaling between the 2nd and 4th digit, and previously published results on the 2D : 4D ratio are biased by its covariation with finger length.


Second to fourth digit ratio and the 'big five' personality factors
The 2nd:4th digit ratio and asymmetry of hand performance in Jamaican children
Testosterone, particularly prenatal testosterone, has been implicated in the aetiology of many extragenital sexually dimorphic traits and it is suggested that the 2D:4D ratio may be associated with the expression of other sexuallyDimorphic behavioural traits.

Second to fourth digit ratio, testosterone and perceived male dominance
High prenatal levels of testosterone serve to ‘organize’ male facial features to subsequently reflect dominance and masculine characteristics presumably activated during puberty, and attractiveness is not directly related to testosterone levels.
