Making ergonomics accountable: Reliability, validity and utility in ergonomics methods

In this paper, we discuss the ways in which Neville Stanton has challenged himself, his research colleagues, PhD students, the many co-authors and contributors to his publications, and the entire Ergonomics community to determine what it means for there to be ‘consistent standards for how [Ergonomics] methods are described and reported.’ Only in this way, can it be possible to make claims about whether or not a method in Ergonomics is effective. Given that he is Chartered as both an Occupational Psychologist and an Ergonomist, it is not surprising that he has been concerned with the question of the reliability and validity of Ergonomics methods. In Occupational Psychology, psychometric and personnel selection methods are expected to exhibit acceptable levels of reliability, but this is an expectation which is still somewhat alien to Ergonomics. Neville's work has been instrumental in raising this issue and in providing approaches which can be used to critically evaluate the methods we use. We think that, despite his ground-breaking work, there is still much to do in the Ergonomics community to create the situation for which he has long argued. •An overview and celebration of Neville Stanton's work on the reliability, validity and utility of Ergonomics methods.•A discussion of evaluating the predictive validity of Ergonomics methods, with examples of formulae.•Discussion of how Ergonomics involves a body of knowledge applied through methods, and the implications of this for training and practice.
