    Hi

    I’ve read that the quote along the lines “In God we trust, others please bring data!” is from the writings of W Edwards Deming. Can anyone confirm this and, if so, give chapter and verse?

    Best Wishes

    “In God we trust; all others must bring data.” W. Edwards Deming

    I came across that Deming quote in a book I’m currently reading, Competing on Analytics: The New Science of Winning.

    I can’t claim authorship – I found this via Google (which, I’m surprised you haven’t heard of BC).

    Greetings from Scotland!

    Thank you for your response. Google has indeed reached the wilds of Scotland but fairly diligent research did not yield the actual source. I was hoping to learn e.g. that the quote may be found on page x of his book y or some such reference so that I could look it up and read what else he had to say.

    Best Wishes

    I’ve given you the source – best way to find exact page and verse is to get an electronic copy and search. Otherwise, best that can be done is to cite a chapter as often different printings change page numbers.

    And all hail he who comes from the most holy land, birthplace of the nectar of the gods – I’m a speyside connoisseur myself.

    Thea quote widely attributed to W. Edwards Deming. Interestingly enough wide spread and accurate are not the same.

    I can not find it in any of his writings. I am looking for its source.

    The quote seems to contradict what I have found in his writings. I am interested in the context in which he made the statement (if he did).

    ++++++++
    Two examples (of many) in his writings that seem in conflict with the statement follow, both from the pages of the Second Edition of The New Economics.

    P 35 “The magnitudes of the most important losses from action or inaction by management are unknown and unknowable (Lloyd S. Nelson; see Out of the Crisis, p. 20). We must nevertheless learn how to manage these losses

    He seems to be saying that the most important data can not be captured AND that we need to learn to manage despite our lack of data.

    Later he states we need to be guided by theory.

    P 63 ”A simple example is training. The only immediate evidence is its cost, expense. The effect of training will not be realized for months or even years in the future. Moreover, the effect can not be measured.
    Then why does a company spend money for training? Because the management believe that there will in the future be benefits that far outweigh the cost. In other words, the management are guided by theory, not by figures. They are wise

    The book “Statistically Speaking: A Dictionary of Quotations” gives Robert W. Hayden credit for that statement – unfortunately they don’t had a date of attribution.

    Seems as if hayden didn’t say it.

    Trevor Hastie, Robert Tibshirani, and Jerome Friedman, co-authors of The Elements of Statistical Learning in their Preface to the Second Edition have a foot note which reads: “On the Web, this quote has been widely attributed to both Deming and Robert W. Hayden; however Professor Hayden told us that he can claim no credit for this quote, and ironically we could find no ‘data’ confirming Deming actually said this.”
