The importance off skepticism in performing audits has been recognized from the time the very first auditing standard was implemented (Fullerton and Durtschi, 2012). The recent financial crises and audit failures have caused the profession to reassess and emphasise the importance of skepticism during an audit engagement, ensuring that auditors increase their level of skepticism (Fullerton and Durtschi, 2012). Auditors are now asked to expand their skeptical perspective to the level used by forensic experts, which according to Fullerton and Durtschi (2012) assumes that management is dishonest unless there is evidence to disprove this. The following summary discusses whether a higher level of skepticism by the auditor would enhance audit quality.
Professional Skepticism
Before assessing whether a higher level of skepticism would enhance audit quality, it is important to understand what professional skepticism is. According to Fullerton and Durtschi (2012) the early audit standards define skepticism as an attitude that includes a questioning mind and a critical assessment of audit evidence, which was often interpreted as neither assuming managerial honesty nor dishonesty.
The IAASB staff question and answers (2012) state that The International Standards on Auditing (ISAs) define professional skepticism as an attitude that includes a questioning mind, being alert to conditions which may indicate possible misstatement due to error or fraud, and a critical assessment of audit evidence. This explicitly requires auditors to plan and perform an audit with professional skepticism realising that circumstances may exist that cause the financial statements to be materially misstated.
The IAASB staff question and answers (2012) do mention that it is difficult to capture the definition of professional skepticism in one single definition, however the ISAs definition helps to understand the important elements of professional skepticism.
