Inheriting vs. Developing Data Analytic Tests and Auditors’ Professional Skepticism

As the use of audit data analytic (ADA) tests matures and becomes increasingly common in practice, auditors will transition to a situation where they typically inherit ADA tests developed by others (e.g., other audit team members or a centralized data analytics team). Despite the potential benefits of ADA, using ADA tests inherited from others, rather than developed by auditors themselves, could hinder auditors’ application of professional skepticism due to their lack of psychological ownership of the ADA tests. In an experiment where an ADA test identifies a fraud red flag, we find that auditors who inherited the ADA test are less likely to exercise professional skepticism compared to those who were personally involved in the development of the ADA test. We then provide evidence that informing auditors who inherited the ADA test about the test development activities (e.g., a brief ADA memorandum documenting the ADA’s development) boosts their skepticism levels.
