Deciding which psychological drives to keep, and which to abandon, is the same as figuring out full formal preference (assuming you have more expressive power than just keeping/abandoning), so there is no heuristic for doing that simpler than full formal preference. This problem isn’t just unresolved, it’s almost FAI-complete (preference theory, as opposed to efficient implementation).
