You Ask, I Answer: How Reliable Are AI Detection Tools

In today's episode, John asks for RFPs that specifically prohibit the use of AI. How reliable are current AI detection tools? Current AI detection tools are garbage. They are worthless. They are, they are highly problematic in a variety of ways.

And here's where the problem is. The problem is in false positives. So false positive, there's there's two types of statistical errors that can occur anytime using any kind of detection tool or anything like that. False negative and false positive. What we call type one and type two errors.

A type one error is a false positive, right? You say something is true and it isn't. A type 2 error is you say something is not true and it is true. So a type 2 error would be uh I you I wrote this with AI, you failed to detect it. It is it is in fact AI, but you think it's human led.

That would be a type 2 error. Um that's not terrible. It's not great, but it's not terrible. Where the problem is today is in the type one error, uh, which is you say something you you falsely accuse, right? That's really what that's if we want to get away from the fancy legal or statistical language, type one errors are false accusations.

You use AI to write this, right? Um and you didn't. You didn't. And if there are repercussions that come from the use of uh a flawed tool, like you lose this RFP option, you get kicked out of school, your tenure is suspended as a professor. Um, these are very serious harms.

The problem is, oh, there's many problems. Um, first, all AI is probabilistic in nature. Uh probabilities, anytime you're doing probability and randomness, you're dealing with the fact that you could have random effects. You could have randomness. And a tool that is trying to tell you whether something is AI or not, is by its very nature a probabilistic tool, which means that there can be randomness, which means it can be wrong.

In the case of AI detection tools, they tend to be very wrong. They tend to be wrong anywhere, depending on the tool, five to I don't know, 50% of the time. For example, I took Federalist paper number 10 written by Alexander Hamilton. I put it in an AI tool, a detection tool. One tool said 72% of the document was written by AI.

Now I don't care how good Lynnwell Miranda is, there's absolutely no way Alexander Hamilton used Chat GPT to write Federalist papers. That is a just a time travel impossibility. It's completely wrong. And yet, this tool confidently says 72% of this paper is AI written. I took another article from the New York Times, 1924.

Oddly enough, talking about how immigration was ruining America. Nothing changes. And the tool confidently said 50% of this article is AI written. Ah, not in 1924. Uh, it's not.

And yet, companies and people are using these tools as though they were definitive answers on things. They are not. Another example, I took, I I I had some essays that my kids wrote in 2020 and 2021, long before Chat GPT, long before the Transformers model was available to anybody outside of Google or you know, a couple of very small AI labs. And the tool complicated says, yes, this paper is like 40% written by AI. The student has cheated as though using a tool for what its intended purposes cheating, and flagged it as such.

Guess what? 0% of that paper was written by AI. Because it turns out that high probability writing is also AI writing. So if you are writing a piece of text that is high probability, it's probably gonna get flagged as AI. If you write a book report about the declaration of independence, there's only so many things you can say in a factual book report about that document that will be coherent and meaningful, but will not be high low probability.

They'll not be unique, right? The declaration of independence was written in this year by these people. And if you're writing high probability language, and high probability language is what AI detector tools are looking for, you're gonna get flagged to the eye. Now, here's how this relates specifically to John's question about RFPs. Guess what an RFP is?

It's highly templated language. Highly templated language, right? You have to respond in a certain way. We expect these certain things. We want you to uh write about this thing and the clients that you've done this for and the financing for the project and so on and so forth.

Highly templated language. Guess what an AI detector is gonna say to a an RFP response that uses high probability language? It's gonna say this is written by AI. Even though it's not, even though it's specifically is language that the vendor has asked for, asked for by in the instructions for the RFP, it's going to get flagged. So my advice is twofold.

One, if you are a vendor issue, if you're a company issuing an RFP, do not use AI detectors. They're worthless, they're dangerous, they are counterproductive, and frankly, they make you look like an idiot. And if you are a vendor responding to an RFP, the easiest way that you can prevent being flagged by these tools, you can't prevent the tool themselves, but what you can do is provide documented evidence that you, the person, have in fact you then human-led in the process. The easiest way to do that is record your staff meetings, record your conference calls, your Zoom calls, all these places that you would say, like, hey, let's work on so-and-so RFP. Document that part so that A, the client can see what you're doing, which itself is an important thing to do, and B, when some of that language is later shows up in the RFP, and someone AI detector says, Oh, this is clearly written by ChatGPT, you could say, no, you have the video of me and my team talking about this RFP exactly as written.

Here is the proof that we did not use AI per your request. Um, and there you go. I will say this also philosophically, philosophically for an RFP. If you are issuing an RFP, and your expectation is that people don't use AI, you're doing it wrong. You're doing it wrong because what would I want you to use AI for on RFP?

I would want you to use AI to fact check my submission. I would want you to use AI to check that I didn't miss anything. I would want you to use AI to cover all the basers. An RFP is a highly templated document to begin with. So it's you're not exactly, you're not creating new content for like you know, someone's corporate website.

You're not creating art. You're you're you're it the opposite of art is an RFP. So if someone is using AI for it, what's the problem there? Why is that a problem? I don't that doesn't seem like a problem to you.

That seems like a solution that somebody's saying, hey, I used a this tool, which is functionally a second set of eyes to examine the work that I did to make sure it's quality, right? You require this, this, this, and this in the RFP response. I used AI to ensure the quality. Would you ever tell a company, hey, don't use a second set of eyes, don't use a proofreading team on an RFP? No, you would never say that.

That would be stupid. Um, well, guess what AI is? It's a second set of eyes if you use if you use it smartly. Now, could you have a vendor that submits a great RFP submission and does not in fact know what they're doing? Sure.

But you'll know that if your RFP process, uh when you go through the due diligence, because you're gonna do diligence due diligence, right? You'll know that the moment you talk to them, and you say, like, hey, in your RFP response, you said this, and they're all like, uh, didn't we? Like, okay, then you know. They they did they use AI and they have no idea what they're doing. But that's something you'll suss out regardless, right?

It is if you are any good at vetting, you will figure that out. So that's the answer to the question. Really good question, important question to answer. And boy, are there a lot of ways to do it wrong. Thanks for tuning in.
