Not only that, but that section should also include a monetary deposit that the author forfeits if his predictions turn out to be false.

That I strongly disagree with. We don't want to discourage people from taking risks, we want them to improve with time. If there's money involved, then people will be far shyer about the rigour of the "failure section".

Ideally, we want people to take the most pride in saying "I was wrong before, now I'm better."

Stuart, and Ilkka, how about you guys go first, with your next paper? It is easy to say what other people should do in their papers.

Alas, not much call for that in mathematics - the failure section would be two lines: "if I made a math mistake in this paper, my results are wrong. If not, then not."

However, I am planning to write other papers where this would be relevant (next year, or even this one, hopefully). And I solemly swear in the sight of Blog and in the presence of this blogregation, that when I do so, I will include a failure section.

And the people here are invited to brutally skewer or mock me if I don't do so.

Fine print at the end of the contract: Joint papers with others are excluded if my co-writer really objects.
