This deck explores common logical fallacies that weaken arguments and distort reasoning. Learners discover how flawed reasoning can appear persuasive while actually being logically incorrect. The cards help identify misleading arguments and improve critical thinking in discussions, debates, and decision-making.
Flashcards combined with spaced repetition improve active recall. You review at the right time, retain knowledge longer, and track progress card by card.
Card 1
It dismisses a claim by targeting the person rather than the reasoning.
Explanation
An ad hominem attack shifts focus from the argument’s content to personal traits, avoiding the actual issue.
Common mistake
People often think exposing a real character flaw automatically refutes that person’s reasoning.
Card 2
It rejects a criticism because the accuser is allegedly guilty of the same fault.
Explanation
Tu quoque attacks the opponent’s consistency instead of addressing whether the criticism is valid.
Common mistake
People confuse showing hypocrisy with actually answering the original objection.
Card 3
It accepts or rejects a claim based only on where it came from.
Explanation
The genetic fallacy focuses on the origin of an idea rather than the evidence for or against it.
Common mistake
People assume that exposing a biased source automatically proves the claim false.
Card 4
It preemptively attacks a speaker’s reliability to undermine any future argument.
Explanation
Poisoning the well biases the audience against a speaker so their arguments are dismissed automatically.
Common mistake
People think giving background context about a speaker is always neutral and fair.
Card 5
It claims an argument is invalid because of the arguer’s circumstances or interests.
Explanation
Circumstantial ad hominem suggests bias from circumstances is enough to dismiss an argument, without examining its logic.
Common mistake
People confuse pointing out possible bias with actually refuting the content of the argument.
Card 6
It attacks a distorted, weaker version of the opponent’s actual claim.
Explanation
A straw man argument replaces the real position with a caricature, then refutes that instead.
Common mistake
People think simplified paraphrases are harmless even when they change the original meaning.
Card 7
It shifts the discussion to a side topic that is not logically relevant.
Explanation
A red herring diverts attention so the original claim or problem is no longer being addressed.
Common mistake
People confuse raising a related background point with introducing a distracting tangent.
Card 8
It revises the standard of proof after it has been met to avoid conceding.
Explanation
Moving the goalposts makes a debate unwinnable by redefining what counts as adequate evidence mid‑discussion.
Common mistake
People think clarifying criteria mid‑debate is always neutral rather than sometimes evasive.
Card 9
It cites favorable cases but omits relevant conflicting data from consideration.
Explanation
Cherry picking creates a misleading picture by presenting a skewed subset of the available evidence.
Common mistake
People confuse careful selection of representative data with hiding inconvenient results.
Card 10
It lifts words from their original context to suggest a different conclusion.
Explanation
Quote mining hides clarifying context so the quoted words seem to support something they do not.
Common mistake
People assume any direct quotation is automatically a fair representation of the source.
