Deductive Fallacies

Disciplines > Argument > Fallacies >  Fallacies

Deductive reasoning uses a move from general rules to specific instances. Deductive fallacies fail due to breaking the rules of this form of reasoning.

• Accident: A general rule used to explain a specific case not covered by it.
• Appeal to Common Belief: If others believe it to be true, it must be true.
• Appeal to Common Practice: If others do it, it must be ok to do it too.
• Begging the Question: Circular reasoning to prove assumed premise.
• Ecological fallacy: Conclusion about individual from group data.
• Exception fallacy: Conclusions about group from individual data.
