Biba but how do you decide who is trustworthy
Trust is partly based on instinct, but if you are talking about scientists, and you want an objective definition, if someone can back up their assertion with evidence, if what they say is rational and logical, if they are capable of expressing their thoughts clearly and succinctly, and if they appear to have no political or financial motives for what they assert.
you say it is good that experts disagree
I said it’s good that evidence is continually reviewed and that minds are open as to how best practice needs to change in the light of new evidence. This inevitably involves people changing their opinions and disagreeing with each other.
yet you only agree with those who disagree in the way you agree I have no idea what this sentence means - please don’t accuse me of expressing myself in such a gobbledygook manner.
