I know this isn’t quite rigorous, but if I can calculate the counterfactual “what would the other player’s strategy be if ze did not model me as an agent capable of responding to incentives,” blackmail seems easy to identify by comparison to this.
Perhaps this can be what we mean by ‘default’?
I think this ties into Larks point—if Larks didn’t think I responded to incentives, I think ze’d just help the child, and asking me $1,000 would be blackmail. Clippy would not help the child, and so asking me $1,000 is trade.
