1. Faulty Analogy Fallacy
Maddie Mount

2. Definition
This fallacy comes from assuming that because two things are alike in one way, they are alike in another way

3. Equation X has property Y Z is like X Z therefore has property Y
Example:
A blue bird has wings.
A dolphin is blue, just like a bluebird.
Therefore a dolphin also has wings.

4. What affects faulty Analogy
The amount and variety of examples in the analogy
The number of characteristics that the things being compared share
The relevance of the known similarities to the similarity inferred in the conclusion

5. Proof
Identify the two objects or events being compared and the property which both are said to possess. Show that the two objects are different in a way which will affect whether they both have that property.

9. Examples
How is a raven like a writing desk?
Poe wrote on both
People who buy stocks are no different from people who bet on horses. They both risk their money with little chance of making a big profit
