fallacy

F. Fallacies


Definition

  • A fallacy is a defect in an argument that does not stem from false premises.

  • Detecting fallacies requires examining the content of the argument.

  • Fallacies often lead to false conclusions and can distort the truth.

  • Fallacies are prevalent ideas that many believe are true but are, in fact, false.


Common Fallacy Example

  • An instance of a common fallacy: "It is a common belief that women are worse drivers than men."

  • Fallacies tend to resemble good reasoning but should not be persuasive.


Are Fallacies Arguments?

  • While we label an argument as fallacious, strictly speaking, "fallacy" refers to a specific error, not the argument itself.

  • Arguments that exhibit these errors are instances of particular fallacies.

  • Fallacies are fundamentally considered types of arguments.


Types of Fallacies

A. Appeal to Pity (Argumentum ad Misericordiam)

  • This fallacy occurs when someone appeals to emotions, particularly pity, using unfortunate situations.

  • Example: "The defendant is innocent. His life will be ruined if you send him to jail for murder. Therefore, you must find him innocent."

B. Appeal to Ignorance (Argumentum ad Ignorantiam)

  • It suggests that if something has not been proven false, it must be true, and vice versa.

C. Equivocation

  • This fallacy involves using a single term to represent two different things, creating confusion.

  • Example: "Human beings have hands; the clock has hands."

D. Composition

  • This fallacy asserts that if something is true of a part, then it must be true of the whole.

  • Example: "This tire is made of rubber; therefore, the whole vehicle must be too."

E. Division

  • Involves assuming attributes of the whole must also apply to each part.

  • Example: "The United States is the richest country; therefore, everyone in the U.S. must be rich."

F. Ad Hominem

  • Latin for "against the man"; it undermines an argument by attacking the opponent’s character.

  • Types of Ad Hominem:

    • Abusive: Using insults against the person.

    • Circumstantial: Attacking the person’s situation.

    • Guilt by Association: Associating the opponent with something negative.

    • Tu Quoque: Referring to past actions of the opponent to discredit them.

G. Appeal to Force (Argumentum ad Baculum)

  • Occurs when threats or force replace logical reasoning.

  • Example: "If you don’t accept X as true, I will hurt you."

H. Appeal to the People (Argumentum ad Populum)

  • Relies on popular opinion rather than logical reasoning.

  • Often used to sway emotions in arguments.

I. False Cause

  • Assumes a causation based solely on sequential events.

  • Known as coincidental correlation.

  • Example: "A rise in prices causes fewer people able to eat."

J. Hasty Generalization

  • Generalizes from insufficient evidence.

  • Example: Online impressions based on a singular negative encounter.

K. Begging the Question

  • Assumes as true what one seeks to prove; a circular reasoning error.

  • Example: "I have a right to free speech; thus, you can't stop me from talking."

L. Cause-and-Effect

  • Incorrectly infers a causal relationship between unrelated events.

  • Example: "Ever since you bought that sweater, everything has gone wrong in your life."
