Very interesting thought experiments! If I were ever to go for my masters or doctorate in philosophy, I think you just gave me an idea at least for a lit review! I wonder how the trust game would play out if it used food instead of money? Or if there were time delays on when one of the participants could “cash out”. I know I can’t be the only person to ever think about tweaking the basic game and seeing what those tweaks do, so I know there’s gotta be tons of literature on it.
Thank you for writing about this! I think you made fair points regarding the assertion of “goodwill”.
