Why is it supposedly impossible to prove a negative? If I am wearing a red shirt and say I'm wearing a yellow shirt and ask you to prove I'm not waiting a yellow shirt, it's pretty easy to do so.

Why are philosophers so fucking stupid?

well how do you prove it then

How do you prove a tiny invisible unicorn that orbits the solar system doesn't exist?

The idea is that, e.g. in trying to prove something, you can't derive "false" in that proof. I probably won't explain it well, not being a mathematician, but check these stack answers out:

Why don't you explain it if its so simple?

Doesn't understand burden of proof.

You made the claim. Prove it.

>A common saying in pseudologic is "You can't prove a negative." This is, as the hatnote up top says, simply not true. This is clearly not true because any statement can be rewritten into the negation of its negation. Any provable statement can be written as a negative. For example, "X is true" can be rewritten as "X is not false", a negative statement! If "X is true" can be proven true, then you have also proven a negative statement "X is not false".

>If "X is true" can be proven true, then you have also proven a negative statement "X is not false".

No. "not false" =/= "true".

Especially if "X" isn't a truth statement.

>The idea that God doesn't exist is true
>The idea that God doesn't exist is not false
They both mean the same thing.

no

People see different colors, people see what they want to believe. You are discussing an opinion, a label for color defined by however many colors (shades) you consider main colors.

Given your choice of example, you likely also mistake and misinterpret the definition of "Negative" or you would understand, not have to question.

>>2174271
Are you trolling or actually fucking stupid?

The statement "It's impossible to prove a negative" is demonstrably false and has fuck all to do with the burden of proof.
