In critical reasoning, what is a 'logical fallacy'?

• A. A type of mathematical proof
• B. A flawed argument due to errors in reasoning or evidence
• C. A universally true statement
• D. A detailed factual analysis

Answer: (B)

In critical reasoning, a logical fallacy is a flaw in reasoning that weakens an argument because the conclusion doesn’t properly follow from the evidence or the evidence is unreliable. Recognizing these flaws helps you evaluate whether a claim rests on solid reasoning or on misleading patterns, such as irrelevant information, biased assumptions, or faulty causal links. For example, arguing that a policy must be good simply because many people support it is an appeal to popularity, which doesn’t prove the policy’s merits. It’s not a type of mathematical proof, it’s not a statement that is universally true, and it’s not a detailed factual analysis.
