||Confidence is necessary for effective top management team (TMT) functioning, however overconfidence or hubris has been associated with poor outcomes. Researchers have struggled to untangle questions of how much confidence is functional and whether there are different forms of confidence. Using data from a field study of 54 public high-technology firms we provide a richer understanding of the complex influence of one type of confidence, TMT potency on strategic decision-making. Specifically, using a field study of TMTs of 54 public high technology firms we find potency at least partially mediates the relationship between TMT experience and knowledge, TMT interaction process, and strategic decision speed. Post-hoc analysis of high potency teams suggests that potency may be either functional -- leading to high performance, or dysfunctional -- resulting in low performance. Potency appears to be a multi-faceted construct consisting of both level and domain boundedness. We offer propositions that begin to untangle the origins of functional versus dysfunctional potency or hubris.
