Of course, after you make the precommitment you are no longer a strict consequentialist.

Fair enough. Rather than talking about precommittments to X, I ought to have talked about assertions that I will X in the future, made in such a way that the benefits of actually Xing in the future that derive from the fact of my having made that assertion (in terms of my reputation and associated credibility boosts and so forth) and the costs of failing to X (ibid) are sufficiently high that I will X even in situations where Xing incurs significant costs. Correction duly noted.

Boy would I like a convenient way of referring to that second thing, though.
