A company promotes a new process after one employee's success; therefore, the process will be successful for everyone. Which flaw best describes this reasoning?

• A. Generalization from a single case.
• B. Correlation does not imply causation.
• C. Ignoring alternative explanations.
• D. Scaling issues are ignored.

Answer: (A)

This question tests a tendency to generalize from a single instance. It spots a hasty generalization: drawing a universal conclusion about all employees from the success of just one person. Just because one case went well doesn’t prove the process will work for everyone— outcomes can vary due to individual skills, circumstances, or luck, so more evidence across many people is needed before making a broad claim. The other options describe related but different flaws: mistaking correlation for causation means assuming a cause from a mere association; ignoring alternative explanations means not considering other reasons the success might have occurred; and assuming scalability ignores how results might change when applied more broadly.
