Inherent Outcome-Favorable Biases and Mitigating Effects of Principles-Based Standards: A Study of Accounting Students’ Tax Decisions

This study documents that an outcome-favorable bias is greater when the quantity of information describing a balanced tax-decision context is substantially increased. Second, the study demonstrates that an outcome-favorable bias can be offset by the use of principles-based ethical standards. Specifically, we examine the effect of AICPA Code of Conduct Section 54 for integrity and Rule 102-6 for advocacy. Students volunteered to participate in this study examining the manner in which accounting novices initially process principles-based standards. Prior studies using student subjects in an audit setting have found that principles-based standards were effective only when students had high levels of moral reasoning (Herron & Gilbertson, 2004), and rules-based technical standards had no impact on student subjects when making financial adjustments (Pflugrath, Martinov-Bennie, & Chen, 2007). If professional standards increasingly rely on principles-based standards, then understanding the impact of such standards on future entrants into the profession would provide guidance in the creation and implementation of future standards, as well as assist educators in the development of accounting curricula. We extend the pattern of past research to a tax setting and show that tax-saving recommendations are a function of the presence of a professional standard and the level of contextual detail.
