Logical Fallacies Flashcards
Slippery Slope
A conclusion based on the premise that if “A” happens, then eventually through a series of small steps “B-Z” will happen too. (Basically equating A to Z). SO if we don’t want Z to occur, A must not be allowed to occur either.
What is this an example of:
If we ban hummers because they are bad for the environment eventually the government will ban all cars, so we should not ban hummers
Slippery Slope
Hasty Generalization
A conclusion based on insufficient or biased evidence. In other words you are rushing to a conclusion before you have all of the relevant facts
What is this an example of:
Even though it’s only the first day, I can tell this is going to be a boring course
Hasty Generalization
Post Hoc. (Post Hoc Ergo Propter Hoc)
This is a conclusion that assumes that if A occurred after B, then B must have caused A
What is this an example of:
I drank bottled water and now I am sick, so the water must have made me sick
Post Hoc Ergo Propter Hoc
Begging the Question or Circular Reasoning
The conclusion that the writer should prove is already validated within the claim (Taking for granted something that needs proving)
What is this an example of:
Lying is wrong because people should always tell the truth
Begging the Question/ Circular reasoning
Either/ Or Thinking
A conclusion that oversimplifies the argument by reducing it to only two sides or choices
What is this an example of: Either you love your job, or you hate it
Either/ Or Thinking
False Analogy
Making a misleading analogy between logically unconnected ideas
What is this an example of:
If we can clone mammals, we should be able to find a cure for cancer
False Analogy
Red Herring
A diversionary tactic that avoids the key issues, often by avoiding opposite arguments rather than addressing them
What is this an example of:
The level of mercury in seafood may be unsafe, but what will fishers do to support their families
Red Herring
Argumentum Ad Misericordium (Argument towards pity)
Like a reverse ad hominem which also ignores the question. A fallacy in which someone tries to win support for an argument or idea by exploiting his or her opponent’s feelings of pity or guilt. It is a specific kind of appeal to emotion
