This paper describes the development of the Probability Evaluation Game (PEG): an innovative teaching instrument that emphasises the sophistication of listening and highlights listening as a key skill for accounting practitioners. Whilst in a roundtable format, playing PEG involves participants individually evaluating a series of probability terms and then calling out their evaluations amongst fellow players who have done the same. When listening to peers' responses, any difference in evaluation of the same term confronts players with the knowledge that without skilled, reflexive listening conversations are dangerous playgrounds of miscommunication. The PEG presents a valuable learning opportunity where the potential impact of this issue for accounting and business world can be discussed. This paper details how PEG was developed, its format and how it has been used with students and accounting practitioners. Furthermore emergent, and often intriguing, learning points are discussed and related to accounting and the workplace more generally.
