Humans cannot recognize AI-written reviews - human reviews were often mistaken for AI-generated reviews, and even more frequently, AI-generated reviews were mistaken for human reviews

The Turing test of online reviews: Can we tell the difference between human-written and GPT-4-written online reviews? - Marketing Letters

Online reviews serve as a guide for consumer choice. With advancements in large language models (LLMs) and generative AI, the fast and inexpensive creation of human-like text may threaten the feedback function of online reviews if neither readers nor platforms can differentiate between human-written and AI-generated content. In two experiments, we found that humans cannot recognize AI-written reviews. Even with monetary incentives for accuracy, both Type I and Type II errors were common: human reviews were often mistaken for AI-generated reviews, and even more frequently, AI-generated reviews were mistaken for human reviews. This held true across various ratings, emotional tones, review lengths, and participants’ genders, education levels, and AI expertise. Younger participants were somewhat better at distinguishing between human and AI reviews. An additional study revealed that current AI detectors were also fooled by AI-generated reviews. We discuss the implications of our findings on trust erosion, manipulation, regulation, consumer behavior, AI detection, market structure, innovation, and review platforms.

Seems like good old Word Of Mouth where information is relayed among people who know each other in real life, is probably going to make a big comeback for this kind of stuff.

Because if you can't trust any media on the internet being "real" the only trustworthy sources you'll have is the real people in your real life.

Along with non-profit verified review orgs like Consumer Reports.

Maybe this will lead to the Internet going back to how it used to be in the beginning. Wouldn't that be something.

I would never trust any recommendations of any people I know.

zout

Are you sure? Because that might say as much about you as about the people you know.

Diplomjodler3

•

It definitely does.

The average person is notoriously shit at doing objective analysis, so yeah, you shouldn't trust people you know.

I don't read five star reviews ever anymore. If I want to find a believable endorsement of a product, I'll look for a four-star review that contains a criticism that isn't that bothersome to me personally, but legitimate enough that I can imagine a customer who would be deterred by it.

We moved a year ago, and I found my favorite pizza guy, Tony, by maybe the most convincing online review I've ever read. The most recent review on google maps was a one-star that was basically like "I met Tony and he casually used foul language etc etc there is no need for profanity etc pizza was some of the best I've ever had though"

I read all the one star reviews. If they are all something akin to "my food was too colorful" or "the waitress didn't refill my water enough" then it's probably ok

I love when owners give a sassy response, or when a one star review tells a story about the owner that makes me laugh.

My favorite local pizza shop is several generations family run, everything from scratch, and everything is done a certain way. I know everyone who works there and has ever worked there, and when me and the boys read this review, even though we all moved away, we knew it was true because it's completly on brand.

Best Pizza going, but their menu is on bristle board and they don't do complicated orders.

This is my favorite stupid review from a local bookstore:

Well, how was the fucking pizza?

Tony's great. He does a thing he calls "Detroit style stuffed pizza" which does not really seem to be a Detroit style pizza at all but it's fantastic nonetheless.

A lot of people like his sandwiches and visually they look very appetizing, but for whatever reason they don't hit the spot for me. His pizzas are spectacular, and good breadsticks and wings too.

We need smarter humans.

I completely agree. Schools need more funding

You can't outsmart fake reviews though. At this point the only smart thing is assuming all reviews are fake.

tsonfeir

•

We could, I dunno, ban misinformation 🤷‍♂️

Make it a crime or something.

jol

•

How would you enforce that?

tsonfeir

•

It would be difficult, but it would fund itself. Just fine them enough and they’ll stop.

Yeah, reviews are relatively easy to fake with current technology. They're short and most of them follow a fairly limited set of formats. This isn't like generating hands where there are a ton of ways for an AI to give itself away. Not that most humans are very good at drawing hands.

I mean, just look at reddit. It's full of whole fake threads of bots talking to bots using copied comments and the only way you can guess it's a bot is by going through their history.

Often times reviews are written by people with English not as a first language, or the reviews are machine translated (nowadays with AI itself). Many AIs use real reviews as templates to train on, so its not surprising to me that the differences aren't easily spotted. The main tells are when it uses too flowery language and tone and doesn't get to the point.

To me it seems similar to if you heard an electronic speaker playing a bird call vs. a real bird call, could you tell the real one from a distance?

If you were an expert birdwatcher you could probably tell easier. If the speaker repeated the exact same call on a loop you could tell, if you were in earshot of electronic buzzing in the background you could also, but depending on how sophisticated the speaker is setup (like delay and variety of calls, you might not.

I am not surprised. I can rarely tell the difference.

Is there a non paywalled article somewhere? It asks for a sub the alternative asks for sign up and free trial.

"Interestingly, this effect cannot be explained by differences in participants’ experience with generative AI models, as that variable is insignificant in the mode"

When predictors are correlated, which is most likely the case here, this analysis cannot separately estimate their effects. The software will end up splitting the total effect size between the two predictors. Without describing collineariry between predictors, it's not possible here to judge whether experience with AI is truly unimportant or the analysis is merely incapable of spotting the effect.

As for eroding confidence in reviews, this will make it worse, but I already put next to no stock in user reviews anymore. You don't need AI to make a good human-like review that lies about a product, and there are plenty of those around.
