The **negative proof fallacy** is where one assumes something is true if it cannot be proven false. It can also happen when one assumes that something is false if it cannot be proven true.

An infinite amount of silly statements might be declared and be completely unprovable, hence we cannot assume validity in the face of unprovability. This is what is known as **burden of proof**.

## Negative Proof Fallacy Example

### Ambiguous Negative Proof Fallacy

Argument: “X is true and you can’t prove that X is false, therefore it’s true”

Reality: X might be false and simply because one cannot prove a thing false does not mean it is true.

### Specific Negative Proof Fallacy Example

Person 1: “How do you justify your belief in god?”

Person 2: “Can you prove me wrong?”

Person 1: “I don’t have to prove you wrong, you are the one with the claim”

Person 2: “Your just making that rule up, you have to prove me wrong!”

Person 1: “No, for you see living with this type of ideology is ignorant and stupid, anyone making a positive claim or assertion has the burden to prove the claim. Otherwise, any and every idiot claim and false statement would have to be disproven in order to even live a somewhat normal existence. Allow me to demonstrate ‘there is a purple dragon behind the moon that created the earth…now prove me wrong’. It would be sheer lunacy and outright madness to expect you to have to prove me wrong, but it is logical to have to have me back up my claim”

Person 2: “B-b-b-but…”

Person 1: “There there now, let’s go get some iced cream”
