For example, asking someone “Have you stopped cheating on tests?”, unless it has previously been established that the person is indeed cheating on tests, is a fallacy. A complex question fallacy occurs when someone asks a question that presupposes the answer to another question that has not been established or accepted by the other person.However, there is a difference between them: The complex question fallacy and begging the question fallacy are similar in that they are both based on assumptions.
