That is different from what I was saying. I was referring to explanations of earthquake sensitivity. If one believes that, say, having a headache is a precursor of a magnitude 7 earthquake, then it beggars belief to suppose that the same highly specific cause and the same highly specific symptom may be underlain by two totally different processes.

Mixing "general" psychic ability with earthquake sensitivity is not the same. There is still, to some extent, an inherent improbability in being doubly gifted - if the chances of being earthquake sensitive are one in a million and the chances of being psychic are one in a million then the chances of being both are a long shot indeed. Though you could argue that, say, psychic people are inherently more prone to being sensitive. Either way, the processes by which the prediction is arrived at are different by the psychic or physical route, and I don't see you confusing the two.

Whereas if I see someone saying they predict something for psychic reasons, and then switching to a physical model as it suits them (to avoid admitting a failure), then some hard questions need to be asked.
