I could understand "checking under the bed" to calm the patient's nerves from a purely consequentialist standpoint, but legitimately saying "I don't know, could be demons" is A: saying nothing at all as it could be anything currently unexplainable and B: lending too much credence to a specific unverifiable "cause". As others have said, demons of the gaps. It's not an intelligent position and not particularly interesting. I wish we could all just get to a point where we answer "I don't know" with "We'll find out" instead of "<Popular mythology>!"
