Which problem arises when users focus on a single number rather than a range of potential outcomes or confidence intervals?

• A. Overfitting
• B. Confirmation Bias
• C. Overemphasis on Point Estimates
• D. Lack of Comprehension

Answer: (C)

Relying on a single number without acknowledging uncertainty means treating a point estimate as if it were the exact outcome. In risk analysis, outcomes come with a range of possible values, captured by confidence intervals and scenario analyses that show how much results could vary. When you fixate on that one value, you underestimate tail risks and misjudge how much capital, hedging, or contingency planning you actually need. This tendency—emphasizing a single point rather than the whole distribution—drives overconfidence and poor risk management under uncertainty. The other issues listed describe different problems: modeling to noise (overfitting), seeking confirming evidence (confirmation bias), or simply not understanding the topic (lack of comprehension).
