As a firm believer in TDD and pair programming, I would caution you that since ultimate goal of programming productivity is unmeasurable, defect rate could also just be a measure of how much slower those practices are.

I don't think that's the case, but really we have no way to prove that it's true. Just a word of caution if you are ever trying to convince someone, it's best to be up front with the possible flaws of those studies.
