"Echoes of medieval wrangling about "how many angels can dance on the head of a pin"...."

You might want to do some more reading on that. The question was, are angels purely spiritual or corporeal? If corporeal, the number is finite, if purely spiritual, infinite. The "head of a pin" thing was shorthand for this, not an indication of any real concern with the absolute or approximate value of such a number.

"Point is, how do you set up a control group?"

Why would I do that? Physical science is by definition the wrong tool for the job.

I have never before had anyone raise the exact issues I was suggesting (albeit subtly) and think they were correcting me.
