Logical Fallacies

Appeal to False Authority (argumentum ad verecundium) “False Expert” Examples? I drink Vitamin Water because Brian Urlacher does!

Ignoring the Question Deflecting from the REAL issue Examples? My paper isn’t done today because I was really busy this weekend and my relationship just ended.

Irrelevant Emotional Appeal Using ethos (emotion) unnecessarily to make a point. Examples? You must enjoy seeing people suffer if you don’t support universal health care.

Hasty Generalization Using one or few examples to make a point. Examples? I failed my first quiz in class. What’s the point of trying any more? I can’t stand Bill Clinton, so I’m never voting for a Democrat again!

Card-stacking Information is only presented from one side while the other is given no support at all. “All the cards are stacked on your side!” Examples? A politician just “happens” to be in town when a new school is opening - so they just drop in, hi-jacking the press for their own means. Source: "Card-stacking." Changing minds and persuasion -- How we change what others think, believe, feel and do. Web. 19 Sept

Bandwagon “Everybody’s doin’ it!” Examples? If all of the other industrialized countries are going to year-round schools, we should too!

Begging the Question You assume what you are saying is true. Examples? Abortion is the unjustified killing of a human being and as such is murder. Murder is illegal. So abortion should be illegal. Assuming abortion is murder. Source: "Begging the question - logical fallacies -." The Skeptic's Dictionary - Skepdic.com. Web. 19 Sept

Fallacy of the General Rule What’s true for one is true for all! Similar to Hasty Generalization, involves absolutes Examples? "All chairs have four legs." Except that rocking chairs don't have any legs, and what is a one-legged "shooting stick" if it isn't a chair? Source: "A List Of Fallacious Arguments." Don Lindsay Archive. Web. 19 Sept

False Either/Or Only giving two choices. Examples? Either we put all terrorists in prison, or America is doomed!

False Analogy Claiming two situations are similar, even though they are not. Examples? We should nuke Afghanistan to end the war, just like we did in Japan.

Game On card, create an example of a fallacy of logic. Write the fallacy on the other side of the card. Divide into two teams. See who can identify the most.
