五大常见逻辑错误（常见的11种逻辑错误）

逻辑错误1.草率前提 (Dicto Simpliciter)　　例如：Women are on average not as strong as men and less able to perform well politically. Therefore, women can't pull their weight in government work.

逻辑错误2.过度概化 (Hasty Generalization)　　例如：McDonald's and KFC offer foods with little nutrition, and thus we cannot expect any fast food restaurant to provide us with nutritious foods.

逻辑错误3.因果颠倒 (Post Hoc)　　例如：Most young criminals watch violent movies before they commit their crimes; obviously, violent movies lead to juvenile delinquency.

逻辑错误4.矛盾前提 (Contradictory Premises)　　例如：If God can do everything, can he make a stone so heavy that he can't carry?

逻辑错误5.感性论证 (Ad Misericordiam)　　例如：Think of all the poor, starving African children! How could rich countries be so cruel as not to help them?

逻辑错误6.错误类比 (False Analogy)　　例如：Young children are like flowers---flowers should stay away from terrible weather to grow, so children need to get rid of everything negative.

逻辑错误7.虚假假设 (Hypothesis Contrary to Fact)　　例如：If TV were not invented, today people would never have such wonderful entertainment brought by TV.

逻辑错误8.无关转移 (Red Herring)　　例如：Many people say we need to exploit the outer space, a point which I believe is wrong, because there are so many poor people on Earth who hardly make ends meet.

逻辑错误9.从众错误 (Bandwagon)　　例如：Everyone says it is justified to learn a second language so we must learn one.
