|Abstract: ||The human amygdala responds to
rst impressions of people as judged from their faces, such as normative
judgments about the trustworthiness of strangers. It is unknown, however, whether amygdala responses to
rst impressions can be validated by objective criteria. Here, we examined amygdala responses to faces of
Chief Executive Of
cers (CEOs) where real-world outcomes could be measured objectively by the amounts of
ts made by each CEO's company. During fMRI scanning, participants made incidental judgments about
the symmetry of each CEO's face. After scanning, participants rated each CEO's face on leadership ability.
Parametric analyses showed that greater left amygdala response to the CEOs' faces was associated with
higher post-scan ratings of the CEOs' leadership ability. In addition, greater left amygdala response was also
associated with greater pro
ts made by the CEOs' companies and this relationship was statistically mediated
by external raters' perceptions of arousal. Thus, amygdala response reflected both subjective judgments and
objective measures of leadership ability based on
