A famous economist, Albert Hirschman, had a wonderful phrase, "self-subversion." Some people, he thought, were capable of thinking in self-subverting ways. What would a self-subverting liberal or conservative say about the Cold War? A self-subverting liberal might say, "I don’t like Reagan. I don’t think he was right, but yes, there may be some truth to the counterfactual that if he hadn’t been in power and doing what he did, the Soviet Union might still be around." A self-subverting conservative might say, "I like Reagan a lot, but it’s quite possible that the Soviet Union would have disintegrated anyway because there were lots of other forces in play."

Self-subversion is an integral part of what makes superforecasting cognition work. It’s the willingness to tolerate dissonance. It’s hard to be an extremist when you engage in self-subverting counterfactual cognition. That’s the first example. The second example deals with how regular people think about fate and how superforecasters think about it, which is, they don’t. Regular people often invoke fate, "it was meant to be," as an explanation for things.
