Then I'd be skeptical about those results. Releasing the code allows others to judge the likely accuracy and integrity of the results. A lot of things can go wrong in complex, multi-step computational processes. If care and rigor has not been put into them, then I'd have no reason to believe in the integrity of the output. I want the general public right to judge that, as well as build on it when it's useful and valuable. Every publication involving data and technical analysis should publish them to a degree that makes validation possible in at least as detailed a way as portrayed in "Does High Public Debt Consistently Stifle Economic Growth?
