Appeal to Ignorance Fallacy: Definition, Examples, and Rebuttals

📚 Quick Study Guide

🧐 The Appeal to Ignorance fallacy asserts something is true simply because it hasn't been proven false, or vice versa.

🙅‍♀️ It's a logical fallacy because a lack of evidence doesn't automatically make a claim true or false.

💡 Common forms include:
• "No one has proven X is false, therefore X is true."
• "No one has proven Y is true, therefore Y is false."

🧪 Scientific claims require empirical evidence, not just the absence of disproof.

🤔 Rebuttal involves pointing out that the lack of evidence proves nothing and shifting the burden of proof.

⚖️ Remember, absence of evidence is not evidence of absence.

📢 Example: "You can't prove that ghosts don't exist, therefore they must exist!"
