Risk springs from uncertainty,' uncertainty invites error, and, since error can be costly, we would prefer to avoid it (provided, of course, that avoidance is not more costly yet). While there is much in the Noll and Krier article2 about judgmental error under conditions of risk and uncertainty, there is little about ways to avoid it. So avoidance-more accurately, minimization-of error costs is the topic I want to address very briefly and partially here.
