 As with the clairvoyance objection, one response is to move from simple reliabilism to approved list reliabilism (see  §2.1  above). As before, approved-list reliabilists will maintain that a potential attributor constructs lists of belief-forming processes, one for approved process types and one for disapproved types. Perceptual processes (of various sorts) would be on the approved list. Since the people in the evil-demon case use perceptual processes that would be on the approved list, an attributor would consider their resulting beliefs justified—even though s/he is told that the perceptual processes in the evil-demon world are unreliable.
