The auditor’s judgment process has been subjected to extensive study since Ashton’s
seminal work in 1974. In general, the results of audit judgment research are consistent
with those of prior psychological research. The literature review revealed that much of
this research suggests that audit judgment can be improved through the use of decision
aids. The purpose of our research was to analyse the effect of a joint audit on the auditor’s
report. The area of study concerning the joint audit is relatively untouched, in contrast to
that concerning general group decision making in accounting, and there has been little
empirical research on the joint audit. As Francis et al. (2009) acknowledged in their paper,
“…we do not know if the joint audit requirement in France is more efficient or effective
than the single audit approach used in the rest of the world”
