ABSTRACT
This chapter presents the results of experiment designed to investigate differences between the belief revision and open mind approaches. The comparisons carried out between the open mind and belief revision groups would provide an answer related to the effect of the belief revision approach on audit efficiency. Investigating the effect of the evidence evaluation mode is carried out in the case of following an open mind approach between the open mind step-by-step group and open mind end-of-sequence groups, and a belief revision approach between the belief revision step-by-step group and belief revision end-of-sequence groups. The chapter presents an attempt to investigate the effect of employing a belief revision approach on the efficiency and effectiveness of the audit process. As effectiveness is measured in terms of achieving the required outcome, comparing the results of the experiment with the 'benchmark opinion' will enable to draw some conclusions about the effect of the belief revision behaviour on the effectiveness of the audit process.
