Judging for ourselves

Suppose I hear from a trusted friend that The Shining is scary. Believing them, I decide not to watch the film. Later, we're talking about the movie and I say, “The Shining is scary!” My assertion here is misleading and inappropriate—I misrepresent myself as having seen the film and judged whether it is scary. But why is this? In this paper, I clarify the scope of the observation, discuss existing explanations of it, and argue that they are all lacking. I argue that the observation is best explained as a particular instance of a general norm which holds that authorities should make assertions about matters in their authority only if they have judged those matters for themselves. Along the way, I offer a theory of judgment which distinguishes it from mere belief.
