How do you know somebody who calls themselves an expert are 'smart'. Isn't that a religious belief, when you accept what somebody says without question? I don't accept your experts. I reject them. I will not treat them as though they are priests emitting the gospel. Just as I did with the 'experts' who pushed the lipid hypothesis using precisely the same 'peer review' and 'scientific journals'. Over time that turned out to be a fallacy. Why is this any different? You have to be very sceptical of anything that is not subject to double blind testing. Belief and bias affects everybody.
