Abstract: The position of an internal audit function as a “servant of two masters” (i.e. management and the audit committee) may lead to a conflict of priorities. In this setting, the tone at the top set by the Chief Audit Executive (CAE) plays a critical role in balancing the potentially competing preferences of management and the audit committee. We examine whether the emphasis in the CAE’s communication with internal auditors influences their judgments. We also test whether such influence is more pronounced in an internal audit task where potential for justification created through task complexity and ambiguity is high, as compared to low. We test two hypotheses in a mixed experimental design with the communicated preferences of the CAE to subordinates (cost reduction vs. effectiveness of internal controls) as a between-subjects factor, and levels of opportunity for justification (low, medium, high) manipulated within subjects. Findings suggest that the emphasis in the CAE’s message can bias internal auditors’ judgments, and such influence is more pronounced when the opportunity for justification is high, resulting in the elimination of a significantly greater number of internal controls and the design of less effective processes.
