Are any of the leading players in the movement scientists of any kind? I have worked with many people who while being obviously very smart, including engineers of many kinds and software developers, who don't have any idea about errors and compounding of errors.

When I studied physics in the mid-70s a compulsory feature of every experimental report was the expected error in the result which had to be justified with reference to the expected errors in all of the measurement equipment and any other sources of error.

When I got into industry this discipline seemed to be pretty much absent.

In my 40 year career in electronic and electrical engineering I don't think I ever saw an engineer include any information on the expected error of a set of measurements even though most were familiar with the concepts of statistical curve fitting and so on. They were not much better than social scientists and would plot the results of an experiment in Excel, click the button to get a polynomial fit and accept the coefficients as gospel totally disregarding the R value. And most of them didn't care that the polynomial form wasn't even applicable to the data.
