I'd take the imperfect studies listed in the article I provided over two anecdotes. However, for the scenario of using TDD with the Sudoku, where it was done with less chaos, other anecdotes are there: http://johannesbrodwall.com/2010/04/06/why-tdd-makes-a-lot-of-sense-for-sudoko/ http://johannesbrodwall.com/2010/04/06/why-tdd-makes-a-lot-o... I say this as a person who likes Norvig more than I like TDD (I'm interested in TDD to see if it is useful for my day to day work, Norvig is more of my high level guilty pleasure, such as his spell checker article or his speech on using lots of data and then algorithm becomes less important)
