I am unaware of any evidence to ignore. I see lots of anecdotal reports, none of them any more convincing to me than my own. Aside from that, have you any evidence? (And, yes, I have read the puffery in that so-called lab report.)
Your statements about the symmetry of predisposition are well taken but those are partly defined by our personal philosophies. Mine, as I said, is conservative in these matters but I am fully prepared to change, given cause.
