Study Notes
Fallacies in Economic Reasoning
- Post hoc fallacy: the error of reasoning that a first event causes a second event because the first event occurred before the second event.
- Example: a rooster thinks that the sun rises because he crows, and he is proud of it.
Ceteris Paribus
- Means "other things being equal".
- Example: "Every time I go to a basketball game, our team wins" is an example of the post hoc fallacy, not ceteris paribus.
Fallacy of Composition
- The error of reasoning that what is true of the parts is true of the whole, or what is true of the whole is true of the parts.
- Example: a farmer thinks that adding more cows to his land will increase total milk yield, but the cows overgraze and the total milk yield falls.
Other Economic Concepts
- Normative statement: a statement about the way the economic world ought to be.
- Example: "Tariffs and import restrictions make most people worse off" is a normative statement.

- "To better see a football game, one spectator stands. Assuming that everyone trying to get a good view of the game can also stand" is an example of the fallacy of composition.
- "You are not surprised that it has started to rain. After all, an hour ago you just finished washing your car and you know it is raining because you just finished washing your car" is an example of the post hoc fallacy.
