Which of the following is a risk of using heuristics?

• A. Faster decisions with no risk
• B. Improved accuracy in all cases
• C. Overconfidence leading to incorrect judgments
• D. No cognitive bias occurs

Answer: (C)

Relying on heuristics means making quick judgments using simple rules of thumb to save mental effort. The trade-off is speed with potential inaccuracy: these shortcuts can create overconfidence and lead to judgments that aren’t supported by the full evidence. That’s why the best choice is that overconfidence leading to incorrect judgments can occur when using heuristics. The other ideas don’t fit because heuristics don’t eliminate risk or bias, they don’t guarantee better or universal accuracy, and they don’t remove cognitive biases—they can actually introduce them. In everyday family and consumer contexts, this means quick judgments about products, health, or budgeting can feel right but mislead you if you don’t check the details.
