 Fake barn cases, by contrast, may be less easily accommodated by Sosa’s AAA approach. When Henry looks at the only real barn in a countryside full of barn facades, he uses a generally reliable perceptual faculty for recognizing barns, and he goes right in this instance. Suppose we say the accuracy of Henry’s belief manifests his competence as a perceiver. If so, we would have to judge that his belief is apt and therefore qualifies as an instance of knowledge. That would be a problematic outcome because the intuition the case is meant to elicit is that Henry does not have knowledge. There are three ways in which an advocate of the AAA approach might respond to this difficulty.
