Informal fallacies

Informal fallacies are types of invalid reasoning in the context of informal logic. There are fundamentally two ways a informal fallacy can emerge. Either the argument has insufficient justification, invalid reasoning or both.

All the following fallacies suffer from one or more of the former problems:

• Circular Argumentation

• Ad Hominem Arguments
• The Straw Man Fallacy
• A False Dichotomy
• Appealing to Ignorance
• Hasty Generalization
• Red Herrings
• Appealing to Hypocrisy
• The Causal Fallacy
• The Fallacy of Sunken Costs
• Invalid Authority Appeal
• Equivocation
• The Appeal to Pity
• The Bandwagon Fallacy
