A Biochemical Property Relating to Power Seeking in Humans

The disposition to seek power in a social arena is tied in this research to a biochemical marker, whole blood serotonin. This finding constitutes the first systematic evidence of any biochemical property in humans which differentiates power seekers from others. The disposition itself is given empirical content with the use of measures of three components of the Type A behavior pattern--aggressiveness, competitiveness, and drive--and of distrust and self-confidence. The statistical fit with serotonin is very good. This discovery echoes similar findings in a species of subhuman primates.
