Is there a valid test of Herzberg's two‐factor theory?

Abstract

There are several ways of stating Herzberg's two‐factor theory of motivation and each version can be tested in various ways. Those who defend the theory argue that researchers who fail to find support for the theory have usually departed from the procedures used by Herzberg. There have been variations in methods of gathering data, categorizing the responses, and analysing the results. These variations may be justified on the grounds that the strength of any theory lies in its logic and in its ability to withstand deviations from a set method. Some tests of Herzberg's theory are more likely to produce support than others. This was confirmed in a study of London bus crews. However it can be argued that there is more than one valid test of Herzberg's two‐factor theory, though some of these are likely to produce contradictory results.
