Agnosticism
Appearance
Agnosticism is uncertainty that leads one to disclaim any opinion on a matter due to lack of sufficient evidence to justify adhering to a belief about what the facts are. It is sometimes viewed as a cop-out, but in some cases it is the most reasonable stance. An auditor, for instance, would not want to either certify a company's financial statements as fairly presenting the company's financial position or, on the other hand, accuse the company of fraud, without enough evidence.
