Professional Skepticism

AUD tests this with a scenario where management gives a plausible-sounding explanation and asks what a skeptical auditor does. The credited answer almost always corroborates the explanation with independent evidence rather than accepting it because management has “always been honest” or because controls looked fine last year. Watch for the tell of contradictory or inconsistent evidence (a confirmation that disagrees with the ledger, an unusual related-party transaction): skepticism means investigate the discrepancy, never explain it away. AU-C 200 requires this mindset throughout the engagement, and AU-C 240 makes it particularly important for fraud risk — you maintain skepticism notwithstanding any prior experience of management’s honesty.

The classic trap is confusing skepticism (a state of mind) with independence (freedom from impairing relationships) or with audit evidence (the information examined) — you can be perfectly independent yet insufficiently skeptical. Skepticism is neutral: you neither assume guilt nor presume honesty. Memory hook: skepticism is the verb, evidence is the noun — the attitude that drives you to gather and challenge proof.
