The Impact of Cognitive Biases on Fraudulent Behavior : The Leeson Case

Inattentional blindness, also known as perceptual blindness, is the phenomenon of not being able to see things that are actually there. This concept is not covered in traditional accounting classes in general and forensic accounting and auditing in particular. We discuss why forensic accountants and auditors should be aware of inattentional blindness and we show how it may impact the behavior of the individuals investigating and being investigated. We use a video to illustrate how this concept could be meaningfully incorporated into a teaching curriculum with a focus on forensic accounting and auditing. In particular, we provide illustrations of how this video could be used in forensic accounting and auditing classes to heighten student awareness of how "blind spots" could adversely affect the investigation process. We conclude by using the Leeson/Barings scandal (involving the fraud that brought down Barings bank) to illustrate how inattentional blindness can occur in a real-life fraud situation. We also provide additional material showing the relevance of inattentional blindness to the Madoff Ponzi scandal
