The Mayo lighting experiment is an awesome and sadly typical example of the kind of shit poor "research" that goes into the field. With premises, methodologies and outcomes so flimsy a six year old could poke holes in it. Yet these kinds of "studies" are published and taken as a great advances and contributions to "management science".
Before you know it, based on one or two of this "studies", great fads sweep the ranks of professional management and we end up with bizarre and counter-productive management initiatives. When those plans inevitably fails and some consulting firm is brought in and recommends a house cleaning, new management is brought in who's only worth is that they're more up to date on the latest fads and reshape the company along those lines...generating lots and lots of activity (reorg after reorg after reorg) but no actual value.
