I agree with this statement. However, at what point, or what would have to happen for you to cease to trust in these particular third parties. Would there have to be research to contradict the current evidence? Research, so damning that the past decades would be for naught? If so, do you believe such research or evidence would ever see the light of day?

A lot of the loss of trust is due to the lack of accountability and the unwillingness for people/institutions to admit their mistakes publicly and take responsibility. I agree with you that for progress to succeed and for knowledge to be exchanged and for our understanding to flourish we need to seek the advice of experts, but I also understand deeply how the experts have been wrong before. At one point, the experts of North American thought it was best to kill 55 million buffalo and erase a culture.
