34 What are challenges to utilitarianism?

In utilitarianism, the emphasis is on finding the best possible results and the assumption is that we can measure the utilities involved. (This turns out to be more difficult that you might think.) Notice also that “the sum total of utilities” clearly implies that in doing utilitarian analysis, we cannot be satisfied if an act or set of acts provides the greatest utility to us as individuals or to a particular corporation; the test is, instead, whether it provides the greatest utility to society as a whole. Notice that the theory does not tell us what kinds of utilities may be better than others or how much better a good today is compared with a good a year from today.

An individual or a company that consistently uses the test “What’s the greatest good for me or the company?” is not following the utilitarian test of the greatest good overall. Another common failing is to see only one or two options that seem reasonable. The following are some frequent mistakes that people make in applying what they think are utilitarian principles in justifying their chosen course of action:

1. Failing to come up with lots of options that seem reasonable and then choosing the one that has the greatest benefit for the greatest number. Often, a decision maker seizes on one or two alternatives without thinking carefully about other courses of action. If the alternative does more good than harm, the decision maker assumes it’s ethically okay.
2. Assuming that the greatest good for you or your company is in fact the greatest good for all—that is, looking at situations subjectively or with your own interests primarily in mind.
3. Underestimating the costs of a certain decision to you or your company. The now-classic Ford Pinto case demonstrates how Ford Motor Company executives drastically underestimated the legal costs of not correcting a feature on their Pinto models that they knew could cause death or injury. General Motors was often taken to task by juries that came to understand that the company would not recall or repair known and dangerous defects because it seemed more profitable not to. In 2010, Toyota learned the same lesson.
4. Underestimating the cost or harm of a certain decision to someone else or some other group of people.
5. Favoring short-term benefits, even though the long-term costs are greater.
6. Assuming that all values can be reduced to money. In comparing the risks to human health or safety against, say, the risks of job or profit losses, cost-benefit analyses will often try to compare apples to oranges and put arbitrary numerical values on human health and safety.

A general problem with utilitarianism is that, due to the issues in the list above, it can be used to justify actions which many would consider immoral. Further, it does so while giving those actions a veneer of scientific rationality through calculation of costs and benefits. If you see a utilitarian-style analysis that leaves you feeling queasy, often there might be one of the problems in the list above. Next, simply doing a real utilitarian analysis can be next to impossible to do realistically. (See here for an example of just how complicated this analysis can be.) Finally, truly living as a utilitarian may be paralyzing. Can one ever justify taking a vacation when the money might be better spent doing good elsewhere?

Whatever its difficulties, utilitarian thinking is alive and well in US law and business. It is found in such diverse places as cost-benefit analysis in administrative and regulatory rules and calculations, environmental impact studies, the majority vote, product comparisons for consumer information, marketing studies, tax laws, and strategic planning. In management, people will often employ a form of utility reasoning by projecting costs and benefits for plan X versus plan Y. But the issue in most of these cost-benefit analyses is usually (1) put exclusively in terms of money and (2) directed to the benefit of the person or organization doing the analysis and not to the benefit of society as a whole.
