I actually have found an example of a strategy that doesn’t incentivize someone else to self-modify into Hawkbot: https://www.lesswrong.com/posts/TXbFFYpNWDmEmHevp/how-to-give-in-to-threats-without-incentivizing-them
Basically, when you’re faced with a probable extorter, you play Cooperate some of the time (so you don’t always get nuked) but either Defect or Nuke back often enough that Hawkbot gets a lower expected value than Cooperate/Cooperate.
