All models are wrong, but some are useful. George E. P. Box More Quotes by George E. P. Box More Quotes From George E. P. Box All models are approximations. Essentially, all models are wrong, but some are useful. However, the approximate nature of the model must always be borne in mind. George E. P. Box statistics mind science Statisticians, like artists, have the bad habit of falling in love with their models. George E. P. Box statistics falling-in-love artist Remember that all models are wrong; the practical question is how wrong do they have to be to not be useful. George E. P. Box errors remember science The only way to know how a complex system will behave-after you modify it-is to modify it and see how it behaves. George E. P. Box complex-systems behave way Statistics is, or should be, about scientific investigation and how to do it better, but many statisticians believe it is a branch of mathematics. Now I agree that the physicist, the chemist, the engineer, and the statistician can never know too much mathematics, but their objectives should be better physics, better chemistry, better engineering, and in the case of statistics, better scientific investigation. Whether in any given study this implies more or less mathematics is incidental. George E. P. Box engineering branches believe Just as the ability to devise simple but evocative models is the signature of the great scientist so overelaboration and overparameterization is often the mark of mediocrity. George E. P. Box mediocrity signatures simple Discovering the unexpected is more important than confirming the known. George E. P. Box testers unexpected important The business of the statistician is to catalyze the scientific learning process. George E. P. Box statistician learning-process process The old-fashioned idea of a good manager is one who is supposed to know all the answers, can solve every problem himself, and can give appropriate orders to his subordinates to carry out his plans... A good modern manager is like a good coach who leads and encourages his team in never-ending quality improvement. George E. P. Box team order ideas The management system which makes only a pretense of valuing employee involvement and encouraging employee empowerment merely breeds cynicism. George E. P. Box cynical empowerment management To find out what happens to a system when you interfere with it you have to interfere with it (not just passively observe it). George E. P. Box observation research science One important idea is that science is a means whereby learning is achieved, not by mere theoretical speculation on the one hand, nor by the undirected accumulation of practical facts on the other, but rather by a motivated iteration between theory and practice. George E. P. Box practice mean hands The benefits provided by worker participation are twofold. Quality is improved because of the finding and fixing of a very large number of problems, but also, and perhaps equally important, moral is improved. George E. P. Box risk important numbers Management must provide employees with tools that will enable them to do their jobs better, and with encouragement to use these tools. In particular, they must collect data. George E. P. Box data encouragement jobs For the theory-practice iteration to work, the scientist must be, as it were, mentally ambidextrous; fascinated equally on the one hand by possible meanings, theories, and tentative models to be induced from data and the practical reality of the real world, and on the other with the factual implications deducible from tentative theories, models and hypotheses.
