To which I pointed out that a valid argument may have false premises and a true conclusion. Do you really wish to rehash this all again? "Who's on first?" might be more entertaining to the lurkers, after all...

To which I pointed out that a valid argument may have false premises and a true conclusion.

Valid has more than one meaning. I put quotes around it. You asked me what I considered invalid. I answered you.

val·id   Pronunciation Key  (vld)
adj.

1. Well grounded; just: a valid objection.

I do not consider it a "valid" use of the experimental results. Why? Because I do accept the premise. Therefore it is not well grounded to me.
