Trust is a feeling:
Trust is the ‘faith or conviction in the loyalty, strength, veracity, etc., of a person or thing; reliance on the truth of a statement etc., without examination’ … and faith is ‘belief, especially without evidence or proof’ —On Faith and Trust
How does this feeling morph itself into existance? How can we intelligently deal with it?
A couple of useful heuristics in regards to the feeling of “trust”:
First, from Scott Adam’s Loserthink 1
it is a bad idea to trust the majority of experts in any domain in which both complexity and large amounts of money are involved.
Second, my own (example),
if something is controversial, with its heterodox views being censored, there is a good chance of the corresponding orthodox narrative being less than true.
