Wizards seem to be overly skeptical of the information that they get from their magical detection spells, an analogue to what some muggle scientists call algorithm aversion. (As evidenced by the current confusion about Hermione’s nature, and the lack of response when the wards previously identified The Defense Professor as her killer.)
When a magical detection spell says that a human is really a unicorn, is it likelier that the spell is accurate or that whatever Dark ritual fueled Hermione’s resurrection has residual effects that interfere with the usual function of said detection spell?
