not-guilty is not the same as innocent

felipec.substack.com

In many discussions I'm pulled back to the distinction between not-guilty and innocent as a way to demonstrate how the burden of proof works and what the true default position should be in any given argument. A lot of people seem to not have any problem seeing the distinction, but many intelligent people for some reason don't see it.

In this article I explain why the distinction exists and why it matters, in particular why it matters in real-life scenarios, especially when people try to shift the burden of proof.

Essentially, in my view the universe we are talking about is {uncertain,guilty,innocent}, therefore not-guilty is guilty', which is {uncertain,innocent}. Therefore innocent ⇒ not-guilty, but not-guilty ⇏ innocent.

When O. J. Simpson was acquitted, that doesn’t mean he was found innocent, it means the prosecution could not prove his guilt beyond reasonable doubt. He was found not-guilty, which is not the same as innocent. It very well could be that the jury found the truth of the matter uncertain.

This notion has implications in many real-life scenarios when people want to shift the burden of proof if you reject a claim when it's not substantiated. They wrongly assume you claim their claim is false (equivalent to innocent), when in truth all you are doing is staying in the default position (uncertain).

Rejecting the claim that a god exists is not the same as claim a god doesn't exist: it doesn't require a burden of proof because it's the default position. Agnosticism is the default position. The burden of proof is on the people making the claim.

My example, that I made up on the spot, that there is a teapot orbiting Jupiter that will grant you one wish if you sing certain words every night for one year, is not impossible, just extremely unlikely?

Yes. That's a foundation of science: you cannot know something with 100% certainty.

The fact that you cannot do the same would seem to indicate a failure in your rationality, in my opinion.

I did not say I cannot do the same, I said do not do the same.

This is shifting the burden of proof: you want me to prove to you how X is not impossible. I don't have to do that, because I'm not making any claim. You can believe whatever you want.

If you want me to believe that X is impossible, then you have the burden of proof. But you can't do that, so you have no justification in questioning my unbelief.

I am perfectly entitled to stay in my skepticism. What you do is up to you, I'm not questioning your belief.

I do not want you to believe anything is impossible, what you do is up to you. I am simply commenting that your inability to concede that the extraordinary magic space teapot that I admit to you I fabricated on the spot does not possibly exist indicates a failure in your rationality.

You are welcome to hang on to your skepticism and hold a belief that it may exist, but the fact that you are not singing the song and dancing the dance (I assume) every night would indicate you don't think it exists any more than I do (which is not at all), since the payoff is so large for such a small cost.

I don't have an inability to do that. And even if I did, you are making an extraordinary claim, which requires extraordinary evidence. And if you think you can easily dismantle philosophical skepticism, I don't think you understand why it exists in the first place.

but the fact that you are not singing the song and dancing the dance (I assume) every night would indicate you don't think it exists any more than I do (which is not at all)

I specifically said I do not believe it exists. It seems you don't understand my position.

You said it was extremely unlikely but not impossible. If there is even a .000000001% chance you should be doing the song and dance because of the payout. Do you disagree?

Yes, I disagree, because I'm not a Bayesian. I don't believe X .000000001%, I don't believe X.
