AI Overview
The shifting the burden of proof fallacy occurs when someone makes a claim but demands others disprove it, rather than providing evidence themselves. This error incorrectly transfers the duty of validation (onus probandi) from the claimant to the skeptic. It is often used to defend unproven or irrational beliefs.
Key Aspects of the Fallacy:

Fundamental Rule: The person making a claim, especially an extraordinary one, bears the burden of proving it.
Argument from Ignorance: It is a form of argumentum ad ignorantiam, falsely assuming a claim is true simply because it hasn't been proven false.
Unfalsifiable Claims: It often involves assertions that cannot be tested, such as "invisible ghosts live in my house, and you can't prove they don't".


Examples:

Conspiracy Theories: "The government is hiding aliens. Prove they aren't!".
Supernatural Claims: Asserting that psychic powers exist, then challenging skeptics to prove they do not.
Daily Conversation: "I know my business plan will work, I don't need to show you projections—show me why it won't work".
