In-Class Fallacy Exercise

Take-Home Fallacy Assignment

Instructions:

Review your notes. Identify at least one fallacy per example.

Identify the fallacy by name, then explain so that someone who had never taken a class on fallacies would understand why you would question the argument.

Remember: (You must explain the fallacy. Just labeling the fallacy will not earn you credit.) Apply it to the argument! (Don’t just define the fallacy; show how it is used in the argument).

Example:

“I really don’t think you should buy a Ferrari. Someone told me that Ferrari’s have a very bad repair record.”

Questionable Authority: Who is the “someone” who said that Ferrari’s have a bad repair record? If it were a mechanic, I might be more likely to accept the argument. But without knowing who the authority is, I have to question the argument.
