Well, okay, what you saw suggested to you that Connie has no paranormal abilities. But, what I am saying is that what you saw should not have suggested that Connie has no paranormal abilities but that, if she does have the paranormal ability being tested for, she did not demonstrate this ability on this occasion and under these circumstances.
Sorry, but this is just silly. All prior evidence says that no-one has ever had any paranormal ability, and that nothing paranormal has ever been shown to exist. Sure, in theory we can't be 100% sure that the paranormal does not exist, but in practice you would be a fool not to act as if it were certain. The burden of proof lies squarely on the claimant. Until Connie can prove that without doubt she does have paranormal abilities, she does not have those abilities. Absence of evidence is evidence of absence. Certainly not absolute proof of absence, but with the only evidence saying that there is nothing there it is just silly to keep assuming that there might be.
The evidence that Connie has magic powers is exactly as strong as the evidence that I have a pet Tyrannosaurus Rex in my flat. It's not just that there's evidence to suggest it's the case, it's also that it's not physically possibly to fit one in there. Pointless semantics about absolute certainty are, in fact, pointless. Given probabilities that would run out of electrons before you run out of zeros, there's really no point in worrying about the fact that there's a "1" at the end somewhere.
Connie Sonne does not have paranormal abilities. End of story. Until she demonstrates otherwise, there's absolutely no point in saying anything else.
