What Cofty said.
I have had this argument, the one made in the O.P, from several JW's since I have left, and it is, as Cofty says, utter nonsense.
Of course we ,at some point, have to trust that the people working in a particular field have done their studies properly, that they are honest, and that we understand the nature of their findings.
The latter takes a little work on our part, and with all due respect, I think you need, dear E.O.M , to do some reading yourself at least.
Scientific studies are subject to peer review, the evidence is laid out for all to see, results can be tested. It does not take anything in the way of faith to trust that the conclusions are true.
Having said that, caution is called for, there have been frauds in Science, but the fraudster has a huge amount to lose, as opposed to religious hucksters.
Since leaving the W.T, and educating myself, I have learned the art of Critical Thinking, and now have a fully functioning BullS**t Meter, so I certainly do not accept things just because the source may have been trusted by me or others in the past. Respected Academics and Scientists can be wrong, or sometimes Headline seeking, wanting notoriety.
I decided early on after leaving I would be fooled no more, or shame on me.
