Well, because the laws of physics do not react to doubt (someone may doubt the existence of Newton’s Third Law, but that won’t protect them from beng hit by a train), doubt should not have a place in defining what is paranormal, i.e. in violation of the laws of physics. Consider someone giving a demonstration of a heavy object floating in midair:
Audience: WOW! That must be the work of something paranormal!
Exhibitor: No, it’s just an application of superconductivity combined with magnetism.
Does the fact that the audience was unfamiliar with the relevant laws of physics justify the “paranormal” label? Suppose the Exhibitor never explained the actual science involved, letting each audience member continue to believe they’d witnessed a paranormal event. Does that unshattered belief make the event paranormal? Suppose some time later, an audience member describes the event to a nonwitness, who doubts the veracity of the account. Does that doubt make the event paranormal? Exactly when does the paranormal label attach, anyway?
Now suppose the Exhibitor isn’t a flesh-and-blood person, but just the randomness of the universe, which one day gives a spectacular display to a bunch of witnesses, with the same (unexplained) results. Does it only become “paranormal” as soon as someone who didn’t see it, doubts it? By that logic, anything that was ever doubted by anyone could qualify as paranormal. Your definition seems restricted to scientists, though, so is something only paranormal if it is doubted by someone with a university degree in a scientific discipline?
Actually, that sounds bang-on to me (and nearly identical to the definition I offered earlier in the thread) except you’re putting too much weight on “currently known” to justify too broad a use of the word, in places where “unexplained” would do nicely. Heck, Columbus had no knowledge of the Americas when he set sail for Asia. That doesn’t make the Americas paranormal by European standards. Even when Columbus returned, describing all the wierd things he’d seen, some scientists of the day might have thought such things impossible. That doesn’t make the Americas paranormal, either.
Incidentally, do reputable scientists ever actually use the word “paranormal”? Seems to me if they saw something the violated known laws of physics, the first thing to do would be to check their instruments, then test again, then make a note of the event (if it recurs) and continue analysis, on the assumption that every effect has a cause, even if the cause is currently unclear or generally assumed to not exist.
