In this concluding part of our discussion of The Social Problems of an Industrial Civilization - one of the texts comprising the famous Hawthorne Studies - we devote more attention to Mayo's social commentary, the methodological implications of qualitative empirical research as well as to the remaining three case studies. Learn more about what Mayo and colleagues did, how they came about to realize the significance of their findings, and why none of this has any bearing on the social problems of a post-WW2 industrial civilization.
