I think it&#x27;s better to have some weighted account of what you know and don&#x27;t know then to assume that any process, framework, theory, or person can&#x27;t be relied on for signal.<p>Daring to have an opinion and daring to be wrong can be just as much of an exploratory process; that, and it sounds less anxious.<p>A lot of people say &quot;nobody knows anything!&quot; and leave it at that. It&#x27;s more often used as an anti-intellectual tool, or a license to say whatever you want since you&#x27;ve just established that everyone in the room is ignorant.
