Abstract. Contrary to the claims put forward in “Evaluation of measurement data – Guide to the expression of uncertainty in measurement”, issued by the Joint Committee for Guides in Metrology, the error concept and the uncertainty concept are the same. Arguments in favour of the contrary have been analyzed and were found not compelling. Neither was any evidence presented in this document that “errors” and “uncertainties” define a different relation between the measured and the true value of the variable of interest, nor does this document refer to a Bayesian account of uncertainty beyond the mere endorsement of a degree-of-belief-type conception of probability.

Short summary
Contrary to the claims put forward in “Evaluation of measurement data – Guide to the expression of uncertainty in measurement”, issued by the JCGM, the error concept and the uncertainty concept are the same. Arguments in favour of the contrary were found not compelling. Neither was any evidence presented that “errors” and “uncertainties” define a different relation between the measured and the true value, nor is a Bayesian concept beyond the mere subjective probability referred to.
