Appeal to Ignorance

Claiming something is true because it hasn't been proven false, or false because it hasn't been proven true. Absence of evidence is not evidence of absence — but it's also not evidence of presence.

Example

"You can't prove aliens AREN'T visiting Earth, so they must be."

Theories on Conspirafy that exhibit this fallacy

• The Illuminati and New World Order — "You can't prove the Illuminati DON'T exist, therefore they do"
