Take a look at the web-of-trust concept in PGP - this might give you some ideas: https://ldlus.org/college/WOT/The_PGP_Trust_Model.pdf
I have published on easily programmable and psychologically interpretable models of trust. In short someone tells you that something occurs with probability p, but you have a certain trust/mistrust of this person (or source of information) and instead of p, you say the probability must be p'. The function f(p) =p' gives a subjective probability from a source probability p. Read this:
