  1. Common Logical fallacies Warrants that don’t work

  2. Ad Hominem Attacking the character of the arguer rather than the argument itself. For example: Her opinion about the election is obviously idiotic; she is blonde.

  3. Ad Hominem attacks people, not ideas. Why would I vote for Obama Care? Don’t you know Obama is a satanic terrorist? Bill Clinton’s affair has shown that he is immoral, therefore his approach to national debt is meaningless.

  4. Bandwagon Suggesting that a person should agree to something because it is popular. For example: Everyone tells a white lie sometimes, so it must be okay to lie.

  5. Bandwagons don’t think for themselves. You should definitely jump off of that cliff; everyone is doing it. We can all agree, everyone is crazy. Galileo’s unpopularity clearly shows the earth revolves around the sun.

  6. Begging the Question Using circular reasoning to prove a conclusion. For example: The bible is an infallible source of moral principles because the bible says so.

  7. Question beggars bring nothing to the table We should all vote for a minimum wage increase because a wage increase is most desirable. President Obama is a great communicator because he has a knack for talking effectively to people.

  8. Either/Or (false dichotomy) Presenting someone with a limited choice, when other choices are possible. For example: It’s either all or nothing.

  9. False Dichotomies limit our options Socrates was either the wisest man alive or he knew nothing. They are either for us or against us.

  10. Post Hoc Reasoning Arguing that one event caused another when they are unrelated For example: Because my professor assigned too much homework, I wrecked my car.

  11. Post Hoc reasoning is a lost cause Welfare recipients are to blame for the increase in unemployment. Eliminating homosexuality would cut down on the spread of HIV.

  12. Hasty Generalizations Using a part to make an inaccurate claim about a whole For example: Michael Jackson’s untimely death shows that all rock stars meet with premature death.

  13. Hasty Generalizations jump to conclusions That guy was jerk, which just proves that all men are scum. If you’re on welfare, you clearly don’t want to get a job.

  14. Non Sequitur Stating a conclusion that does not follow from the premises For example: I had pizza for breakfast, so everything will be okay.

  15. Non Sequiturs are nonsensical Cars go fast. Bikes go slow. Bikes should stay off the road. I’m really good at tennis, so I would make an excellent president of the United States.
