The alternatives available are the exercise of power (coercion), incentives (calculation), acculturation (aligning interests), and communication—the four basic modes of human interaction. PAT implies the possibility of using just one of these (calculation) to solve the problem of creating order and predictability under uncertainty between divergent (real) individuals—and it should be questioned on that ground alone. A more commonsense approach is to do what we all do, learn from the experience of interacting with agents generally, and with this particular agent over time.
