So, he says "most" of the 80% of NDEers stop watches... This means that at the very least, 51% of the 80% stop watches. That places us at about 40% at the very least. Again, comparing this to the 4% of non-NDEers, there is a chasm of difference.
As for Morse's numbers, I quote: "Morse says 4% of normal adults and 2% of out-of-body experiencers claim they make watches stop". An OBE is not an NDE, and vice versa. Do not equate the two. This statement says nothing about NDEers, only OBEers.
I accept your point about definitions.
Forgetting the Morse survey. From a skeptical POV there's still nothing to it. Nothing at all.
You can't just say most must translate into a figure greater than 50%.
That's something we might expect, but one of the important steps in making a skeptical appraisal is to compensate for the bias caused by expectation.
The percentage is not stated so therefore is unknown (I'm still bugged by the question: why is it unknown? Seems a huge oversight on behalf of the author - did he forget to count them?)
But anyway, as I said earlier: there is nothing here but anecdotal evidence, and anecdotal evidence is no evidence at all.
Anyone who can stop watches, do what the earlier poster said, go visit James 'The Amazing' Randi and collect your million dollars.
