Types of Fallacies

Fallacies of Pathos

  • Argument to the People (Appealing to Stirring Symbols)
    • Appeals to the emotions of the audience, often using charged language and imagery.

    • Claiming something is true because it hasn't been proven false, or vice versa.
  • Appeal to Popularity—Bandwagon
    • Suggesting that a claim is true because many people believe it.
  • Appeal to Pity
    • Manipulating emotions to elicit pity in order to gain support for a claim.
  • Red Herring
    • Introducing irrelevant material to divert attention from the original issue.

Fallacies of Ethos

  • Appeal to False Authority
    • Using an authority figure to endorse a claim when the authority lacks relevant expertise.
  • Ad Hominem—to the Person
    • Attacking the character of the person making the argument rather than the argument itself.

  • Part for the Whole
    • Assuming that what is true for a part is true for the whole (or vice versa).
  • Post Hoc, Ergo Propter Hoc
    • Assuming causation from correlation, specifically: if one event follows another, the first must be the cause of the second.
  • Begging the Question—Circular Reasoning

    • Presenting two options as the only possibilities when more exist.

    • Suggesting that a minor action will lead to major and oftentimes ludicrous consequences.
  • False Analogy
