In my post on why mass surveillance is not normal, I referenced how the Wikipedia page for the Nothing to hide argument labels the argument as a “logical fallacy.” On October 19th, user Gratecznik edited the Wikipedia page to remove the “logical fallacy” text. I am here to prove that the “Nothing to hide” argument is indeed a logical fallacy and go through some arguments against it.

The “Nothing to hide” argument is an intuitive but misleading argument, stating that if a person has done nothing unethical, unlawful, immoral, etc., then there is no reason to hide any of their actions or information. However, this argument has been well covered already and debunked many times (here is one example).

Besides the cost of what it takes for someone to never hide anything, there are many reasons why a person may not want to share information about themselves, even if no misconduct has taken place. The “Nothing to hide” argument intuitively (but not explicitly) assumes that those whom you share your information with will handle it with care and not falsely use it against you. Unfortunately, that is not how it currently works in the real world.

You don’t get to make the rules on what is and is not deemed unlawful. Something you do may be ethical or moral, but unlawful and could cost you if you aren’t able to hide those actions. For example, whistleblowers try to expose government misconduct. That is an ethical and moral goal, but it does not align with government interests. Therefor, if the whistleblower is not able to hide their actions, they will have reason to fear the government or other parties. The whistleblower has something to hide, even though it is not unethical or immoral.

You are likely not a whistleblower, so you have nothing to hide, right? As stated before, you don’t get to make the rules on what is and is not deemed unlawful. Anything you say or do could be used against you. Having a certain religion or viewpoint may be legal now, but if one day those become outlawed, you will have wished you hid it.

Just because you have nothing to hide doesn’t mean it is justified to share everything. Privacy is a basic human right (at least until someone edits Wikipedia to say otherwise), so you shouldn’t be forced to trust whoever just because you have nothing to hide.

For completeness, here is a proof that the “Nothing to hide” argument is a logical fallacy by using propositional calculus:

Let p be the proposition “I have nothing to hide”

Let q be the proposition “I should not be concerned about surveillance”

You can represent the “Nothing to hide” argument as follows:

pq

I will be providing a proof by counterexample. Suppose p is true, but q is false (i.e. “I have nothing to hide” and “I am concerned about surveillance”):

p ∧ ¬q

Someone may have nothing to hide, but still be concerned about the state of surveillance. Since that is a viable scenario, we can conclude that the “Nothing to hide” argument is invalid (a logical fallacy).

I know someone is going to try to rip that proof apart. If anyone is an editor on Wikipedia, please revert the edit that removed the “logical fallacy” text, as it provides a very easy and direct way for people to cite that the “Nothing to hide” argument is false.

Thanks for reading!

    From your source, we must first have P -> Q. You have not demonstrated that. Sure, if we assume that P -> Q, then P -> Q. That’s a tautology. OP’s goal is to prove P -> Q. I’ve said this multiple times as did OP. Your consistent sharing of a truth table is a necessary condition for P -> Q but it is not sufficient. If P -> Q, then the truth table is valid. That’s modus ponens. You still gotta show (or assume like you have been) that P -> Q.

    To quote OP,

    P -> Q

    I will be providing a proof by counterexample

    In other words, P -> Q is an unproven hypothesis. If P -> Q, then your truth table is correct. If we assume P -> Q, then your truth table is correct. But propositional calculus unfortunately requires we prove things, not just show things that will be true if our original assumption is true.

      With all due respect, get your head out of your arse and read this from what I posted:

      While modus ponens is one of the most commonly used argument forms in logic it must not be mistaken for a logical law; rather, it is one of the accepted mechanisms for the construction of deductive proofs that includes the “rule of definition” and the “rule of substitution”.

      Emphasis is mine. I cannot scream hard enough to get this simple message across to your flipping head. You are reading it wrong, and if you had done one class of prepositional calculus you would have known, therefore you haven’t.

      As for your foundationalist pursuits, most of science advances without getting back to the foundations, just as calculus was in practical use long before it was formally proven. So you see a person (OP) struggling with basic conception and composition of his argument, let alone the formal expression, and you raise the bar to the level of logical foundations of mathematics? If not dishonest, this is utterly unproductive.

        Sure! Let’s go back to foundations. The foundation of modus ponens is, quoting your source,

        If P -> Q and P, then Q

        In order for this to work, we must have both P -> Q and P. Will you please quote OP that shows we have P -> Q, as I have asked from the beginning, instead of making personal attacks? Alternatively, if I’m missing something in my foundations, such as “P -> Q can always be assumed in any basic symbolic context without proof,” educate me. As you have bolded, we can use modus ponens if and only if (necessary and sufficient) we have its requirements. If we don’t, per your source, we cannot use it to prove anything.

          No one is attempting to prove bleeding P->Q here.

          If P -> Q and P, then Q

          Sure, and when ~P^Q, then P->Q is still not false, and you can further use it in a proof, in the context of other given statements.

          This was never presented as a method to show that P->Q, which arguably can only be shown with data.

            other given statements

            Perhaps this is our fundamental misunderstanding! I am operating under these statements

            P: I have nothing to hide Q: I should not be concerned about surveillance

            In my opinion, everything after this is OP’s proof, ie we have no given statements ergo you calling out modus ponens is meaningless because, from our foundations, we could theoretically have ~P^Q, P^~Q, P^Q, and P^Q. Our foundation provides no context on how P and Q interact, and, as both of us state, albeit for different reasons, we cannot conclude anything about their interaction.
