How should we accommodate our future misbehavior? The answer turns on how bad it will be

Professor Procrastinate receives an invitation to review a book. Best would be to accept it and then write the review. But if he accepts it, he will never get around to writing. And this would be worse than declining. Should he accept? Possibilists say yes, Actualists say no, and I say we need more information. In particular, we lack some information about the level of goodness of the various options. For example, we lack information regarding how much better it would be to accept and write than it would be to decline. In the course of defending my view, I discuss its implications for ethical theory and our everyday actions.
