Which fallacy involves introducing irrelevant information to distract from the main issue?

• A. Red herring
• B. Post hoc
• C. Slippery slope
• D. Ad hominem

Answer: (A)

The idea tested here is using a red herring — a distraction tactic that introduces information unrelated to the main issue to derail the discussion. When someone brings up something irrelevant, the focus shifts away from the argument at hand, making it harder to address the real point. For example, if a debate is about the effectiveness of a policy and someone starts talking about an unrelated personal grievance, the distracting detail doesn’t help evaluate the policy itself; it sidesteps the actual evidence and reasoning. This differs from other common fallacies: post hoc mistakes causal order, assuming A causes B just because A happened before B; slippery slope argues that a small step will inevitably lead to a chain of extreme outcomes; ad hominem attacks the person rather than the argument itself. These address different errors in reasoning, not the use of irrelevant information to divert attention.
