Professional scepticism

Professional scepticism is an attitude that includes a questioning mind, alertness to conditions indicating possible misstatement and a critical assessment of evidence. It applies throughout the engagement, including when information appears to support management’s position. A sceptical auditor seeks corroboration and considers contradictory evidence without presuming dishonesty. It is particularly important when evidence is inconsistent, the reliability of documents is questionable or management uses uncertain assumptions. The auditor considers both supporting and contradictory information rather than seeking only evidence that confirms an initial view.
