Depends on how much information you have about someone, obviously, but one could look for situations with traditional game theory scenarios—may I’m just trying to use fancy words. When I’m in public places I sometimes watch people, trying to imaging (or just taking note) of what kind of person they are—just for fun, there is rarely any feedback but for example if a person goes through some trouble to but a book back on the right spot on a shelf in a library (in a situation where thinks it’s not being watched) I take that as quite good correlate for trustworthiness/ability to uphold social contracts.
