Campbell’s Law: Why your metric will be gamed

The more any quantitative social indicator is used for social decision-making, the more subject it will be to corruption pressures and the more apt it will be to distort and corrupt the social processes it is intended to monitor.

–Donald Campbell, 1979

Campbell, originally an experimental psychologist and trained in experimental method as was customary in his field, soon realized that true experiments could not be done in any of the social sciences because no one would let social scientists treat human beings the way laboratory scientists treated rats and other experimental animals. You couldn’t manipulate people that way because they were free enough to reinterpret the conditions of any experiment and because the institutions where experiments were done were sensitive to the public relations, if not always the moral, issues involved.


An experimenter might choose a condition for the social program to be tested, but the subjects of the experiments–organizations and the people responsible for them–inevitably and quickly understood how the numbers their actions piled up could be used in ways that might help or hurt their interests. And so, just as routinely, did their best to make sure that the numbers came out the way that gave the best outcome from them, manipulating them in ways their organizational positions and knowledge made available to them. Who knew better how to to that? And that’s been a robust finding. It’s what people organizations do, if they can (and usually they can).

Why Management Science Fails to Perform, according to Peter Drucker

Parts exist in contemplation of the whole.

There is one fundamental insight underlying all management science. It is that the business enterprise is a system of the highest order: a system whose parts are human beings contributing voluntarily of their knowledge, skill, and dedication to a joint venture. And one thing characterizes all genuine systems, whether they be mechanical like the control of a missile, biological like a tree, or social like the business enterprise: it is interdependence. The whole of a system is not necessarily improved if one particular function or part is improved or made more efficient. In fact, the system may well be damaged thereby, or even destroyed. In some cases the best way to strengthen the system may be to weaken a part–to make it less precise or less efficient. For what matters in any system is the performance of the whole; this is the result of growth and of dynamic balance, adjustment, and integration, rather than of mere technical efficiency.

Primary emphasis on the efficiency of parts in management sciences is therefore bound to do damage. It is bound to optimize precision of the tool at the expense of the health and performance of the whole.

Organization Design: “All the elements interact in a system”

Organizations, like individuals, can avoid identity crises by deciding what it is they wish to be and then pursuing it with a healthy obsession.

Some organizations do indeed achieve and maintain an internal consistency. But then they find that it is designed for an environment the organization is no longer in. To have a nice, neat machine bureaucracy in a dynamic industry calling for constant innovation or, alternately, a flexible adhocracy in a stable industry calling for minimum cost makes no sense. Remember that these are configurations of situation as well as structure. Indeed, the very notion of configuration is that all the elements interact in a system. One element does not cause another; instead, all influence each other interactively. Structure is no more designed to fit the situation than situation is selected to fit the structure.

The way to deal with the right structure in the wrong environment may be to change the environment, not the structure. Often, in fact, it is far easier to shift industries or retreat to a suitable niche in an industry than to undo a cohesive structure.

Essentially, the organization has two choices. It can adapt continuously to the environment at the expense of internal consistency—that is, steadily redesign its structure to maintain external fit. Or it can maintain internal consistency at the expense of a gradually worsening fit with its environment, at least until the fit becomes so bad that it must undergo sudden structural redesign to achieve a new internally consistent configuration. In other words, the choice is between evolution and revolution, between perpetual mild adaptation, which favors external fit over time, and infrequent major realignment, which favors internal consistency over time.

–Henry Mintzberg, 1981
