None especially I think (although I haven’t reread it). You necessarily must ultimately take a guess (metaphysical speculation, a leap of faith) and just get on with it; perhaps the difference is in how much the great doubt imposed by this necessary guess influences one’s worldview: the straw rationalist says “great, now we can get on to other things!” and the straw postrationalist says “good enough for the moment, we have to get on with other things”.
To put it in other terms: the straw rationalist becomes cognitively fused with their worldview, and the postrationalist does not. Even when one believes that one is not fused with a worldview, there is almost always a cognitive fusion with one’s metaphysics going on. It’s what gives rise to one’s very experience of reality in the first place.
