This is a thought-provoking article, James. When I was providing therapy, I worked with many individuals who struggled with trust in their romantic relationships. They were hurt before in previous relationships and found it difficult to put trust in their new partner even when there was no reason not to trust them.
My question to these individuals was usually, What if you give your partner trust and see what they do with it?
If we assume someone is not trustworthy, we interact with them in a way that fulfills this expectation. If we assume someone is trustworthy, this also impacts our interactions.
Having more faith and trust in our fellow humans is important!
