What is the main drawback to utilitarian reasoning?

• A. It is difficult to accurately measure both costs and benefits.
• B. It ignores costs and benefits.
• C. It is too costly to compute.
• D. It focuses only on legal compliance.

Answer: (A)

The main challenge here is accurately measuring and comparing the costs and benefits of an action across all those affected. Utilitarian reasoning rests on evaluating the overall welfare produced, but many important consequences are hard to quantify or monetize—things like pain and pleasure, dignity, environmental effects, or future harms and benefits. When values differ between people and outcomes unfold over time with uncertainty, putting a precise number on costs and benefits becomes messy and controversial. This makes it difficult to determine which action truly maximizes total welfare. So, the key difficulty is the measurement and comparability of costs and benefits, not the idea that we ignore them, avoid computation, or focus on legality.
