It has been shown that a smaller ratio between the length of the second and fourth digit (2 D :4 D ) is an indicator of the exposure to prenatal testosterone ( T ). This study measured the 2 D :4 D of men and assessed dominance as a personality trait to investigate indirectly if the exposure to prenatal T is related to a dominant personality later in life. Results showed that men had a more aggressive dominant personality when having a more masculine (lower) 2 D :4 D , while there was no relationship between sociable dominance and 2 D :4 D . Findings from this study indicate that it is important to distinguish different forms of dominance since other studies failed to find relationships between dominance and 2 D :4 D . Aggr.
