Which statement best defines critical thinking and provides a relevant example?

• A. Critical thinking is simply agreeing with the majority opinion.
• B. Critical thinking is emotional decision making.
• C. Critical thinking is biased reasoning based on assumptions.
• D. Critical thinking is objective analysis to form a judgment; for example, evaluating data and identifying a flawed assumption in a plan.

Answer: (D)

Critical thinking means looking at information impartially, weighing evidence, and forming a judgment based on reasoning rather than feeling or popularity. It involves analyzing data, questioning assumptions, and checking for logical flaws. In the example, evaluating data and identifying a flawed assumption within a plan demonstrates this kind of careful analysis, where you test premises, weigh alternatives, and spot where a hidden error could mislead the outcome. This is what true critical thinking looks like in practice: an objective assessment that leads to a well-supported conclusion.

The other options miss the mark because they rely on consensus, emotion, or biased starting points rather than objective analysis. Simply agreeing with the majority isn’t evaluating evidence; making decisions based on emotions isn’t analyzing facts; and reasoning that starts from a biased assumption isn’t testing or challenging that assumption.
