Logical Fallacies Flashcards
Post hoc
Assuming that, because one event follows another, the first event was the cause of the second.
Ex: Taxes were raised, then crime went up, so crime went up because taxes were raised.
Red herring
The arguer raises a side issue that has nothing to do with the original issue. It’s meant to distract from the original purpose.
Ex: Grading this exam on a curve would be fair because students and teachers should have a good relationship.
Reductio ad absurdum
Using an absolute to make it seem like denying the arguer’s thesis would be absurd.
Ex: Money always leads to a better education.
Non Sequitur
An argument that doesn’t follow the premise.
Ex: I hear rain falling outside; therefore, the sun is not shining.
Begging the Question
circular logic
Ex: This painting is trash because it is obviously worthless.
False Analogy
attempts to compare 2 things that are not enough alike to make a sound argument
Either or/If then
assuming there are only 2 sides to an issue, ignoring alternative viewpoints
Hasty Generalization
making an assumption about a whole group based on an inadequate sample
Slippery Slope
claiming a chain reaction ending in a dire consequence without proper evidence
Appeal to Authority
Getting readers to agree by having evidence given by a person the reader is familiar with who is not necessarily qualified as an expert
