Trust is an important layer to the human experience that is required, secured and applied to navigate uncertainty in the present. This uncertainty is primarily introduced by human actors capacity for unpredictable actions. Trust is placed in the expectations of others to uphold commitments to fulfil certain obligations in the future that they are judged to have made based on the identities applied to them within an interaction. Trust, like identity, is not static or fixed, but contextually dependent, individually perceived and constantly changing in response to information. For trust to be placed intelligently, identities and their binding to entities must be stabilised by systems of trustworthy information flows that provide assurances in the constancy and continued applicability of these identities within future presents. In doing so, trust structures possibilities from a meaningful experience reducing the complexity of action selection in relation to an uncertain future populated with unpredictable entities.

I also strongly believe that instead of trying to design systems based on a pattern commonly used today of identify, predict and control at ever greater fidelity so as to reduce the uncertainty and need for trust is a mistake.
Trust is a powerful tool that allows us to navigate uncertainty without proscribing the form the future will take. It keeps the future open to possibility and emergence. We should design for that.
