Wired magazine editor Kevin Kelly explains that a great deal can be learned from things going wrong unexpectedly, and that part of science's success comes from keeping blunders "small, manageable, constant, and trackable". He uses the example of engineers and programmers who push systems to their limits, breaking them to learn about them. Kelly also warns against creating a culture (e. g. , school system) that punishes failure harshly, because this inhibits a creative process, and risks teaching people not to communicate important failures with others (e. g. , null results).
