Logical Fallacies And Appeals Flashcards
Uses personal attacks rather than logic. The fallacy occurs when someone rejects or criticizes another point of view based on the personal characteristics, ethnic background, physical appearance, or other non-relevant traits of the person who holds it. When used in politics it is often called “mudslinging.” They are considered unethical because politicians can use them to manipulate voters’ opinions against an opponent without addressing core issues.
Ad Hominem
Attacks a different subject rather than the topic being discussed, often a more extreme version of the counter argument. The purpose of this misdirection is to make one’s position look stronger than it actually is.
Straw Man
Presents limited options, typically by focusing on 2 extremes when in fact more possibilities exist.
False Dilemma/False Dichotomy
Assumes that a certain course of action will necessarily lead to a chain of future events. This fallacy takes a benign premise or starting point and suggests that it will lead to unlikely or ridiculous outcomes with no supporting evidence.
Slippery Slope
When a person’s argument repeats what they already assumed before without arriving at a new conclusion
Circular Argument
A claim based on few examples rather than substantial proof. Arguments based on this fallacy often don’t hold up due to a lack of supporting evidence
Hasty Generalization
An argument that uses confusion or distraction to shift attention away from a topic and towards a false conclusion. Usually contains an unimportant fact, idea, or event that has little relevance to the real issue.
Red Herring
Informal fallacies that occur when an argument incorrectly concludes that a cause is related to an effect. It assumes that because 2 things occurred together, one must have caused the other
Causal Fallacy
When someone continues doing something because of the effort they already put in it, regardless of whether the additional costs outweigh the potential benefits.
Sunk Cost
Happens when a word, phrase or sentence is used deliberately to confuse, deceive, or mislead. Saying one thing but meaning another.
Equivocation
Assumes something is true (or right or good) because others agree with it. This fallacy argues that if everyone thinks a certain way, then you should, too.
Bandwagon
Argues that a proposition must be true because it has not been proven false or there is no evidence against it
Appeal to Ignorance
Focuses on the hypocrisy of an opponent. It deflects criticism away from oneself by accusing the other person of the same problem or something comparable
Appeal to Hypocrisy
Misuse of an authority’s opinion to support an argument. While an authority’s opinion can represent evidence and data, it becomes a fallacy if their expertise or authority is overstates, illegitimate, or irrelevant to the topic.
Appeal to Authority
Appeal to credible authority
Ethos
