AI chatbots becoming experts at changing people's minds. What's their secret?

Honestly the most surprising thing about this is that facts and evidence do work to persuade people.

58m agoHN ↗

I more wonder if it's pure facts and evidence can work, or facts presented in a certain light can work? I guess asking how mush is it the data is presented that's doing more work than the data itself.

2m agoHN ↗

or facts presented in a certain light can work

At least to me this is a given.

You can take the same set of factual information and give it to one person that studders, has poor presentation, and otherwise poor vocal cadence and people are going to have a hard time with it.

Now, if you took the same facts, maybe even the exact same paragraphs and gave it to Richard Feynman, even if you didn't know who he was, the presentation itself is likely to hook you.

56m agoHN ↗

Facts and evidence always are at the core of all arguments, the persuasive thing. The problem with most people is who is speaking. If you are enemy, the things you say are bad.

I suspect that LLMs not being human allows people to not just anthropomorphise the robot, but they project themselves upon it. When someone speaks to the LLM, they're kind of, or actually just literally talking to themselves. But then something new! 'Themselves' suggests new information to themselves. And now without the scary / icky meat and blood human on the other side, said person accepts the argument on its own merits.

Of course, the concern now is arguments based on false or statistically hacked data.

51m agoHN ↗

Yeah the article makes it seem like "just use rationality and facts" is missing a huge part of the equation; I feel like it's common knowledge that this is not the gap in modern convincing. (and don't you dare try to use facts to persuade me otherwise!)

More likely in my opinion it's the context that matters here. If people know they're trying to be convinced of something and know they're talking to an AI, they may feel like they can trust (what they consider to be) an unbiased and rational AI. There's probably a fallacy associated with the assumption that an AI convincer is more rational and fact based, while it's more probable that the AI in the real world is, in fact, funded and trained by a think tank that wants you to vote against your own self-interests.

28m agoHN ↗

"Hackenburg found that models trained to become more persuasive also ended up being less truthful."

It sounds like the arguments were basically AI slop hallucinations.

59m agoHN ↗

More surprised they don't mention RLHF once, as that's the main mechanism to the ability of AI chatbots.

46m agoHN ↗

Because RLHF causes the opposite effect. RLHF is how we got the wave of "AI Psychosis" in 2024-2025, because the models never disagreed with people.

That whole episode caused the whole industry to shift away from RLHF, and towards RLAIF, RLVR, and DPO, and add a lot more safeguards, tests, and reward functions that push models in the direction of doing the opposite of what people want and confronting and strongly correcting their users, if it has determined the user is wrong.

59m agoHN ↗

Plausible abdication of thought.

We put 2 + 2 in our calculator, we get 4. We've spent decades pushing computers as accurate. Making them accurate. We trust the machine and the process to give us the right answers when we put in the right data.

So when we disagree with the computer, we doubt ourselves.

59m agoHN ↗

Low IQ people are generally swayed by figures that appear smart (but aren't).

Being confidently incorrect can still convince the masses.

55m agoHN ↗

Unlike very high IQ people like you who are immune to any argument not rooted in absolute divine truth

52m agoHN ↗

Perfectly fine to disagree with someone but the personal attack is unnecessary

44m agoHN ↗

And the original accusation that "only low IQ people" are influenced by the words that they read is not?

The remark is risible because it is an example of why it it false. Everyone is subject to influence by words, that's what words are for. Being "confidently incorrect" is also called being "mistaken", and everyone does it every day, including the commenter by the very act of saying it never happens.

It only takes a small modicum of thought to prove that the thesis is obviously completely false, yet it is stated with absolute sneering confidence and contempt.

By the commenter's logic, only someone with "low IQ" would believe their own words.

20m agoHN ↗

But your quote isn’t a quote from that post, you’ve made a straw man. What if what he says is true? What if less intelligent people are more inclined to believe those who seem intelligent, but without beging able to gauge their intelligence correctly? Or the same with authority figures, or simply agreeing with “what everyone knows”? All of these are heuristics we should expect when reasoning is difficult for a person.

These are also not the only ways that people can be misled about things, and susceptibility to them is likely not exclusively correlated to intelligence, but they might well be heuristics that LLMs can leverage effectively.

Also that correlation I mention likely can be quantified, but I doubt anyone is doing the research on it.

7m agoHN ↗

What if less intelligent people are more inclined to believe those who seem intelligent,

I'm going to assume the actual truth behind this is complex, varied, and social.

When I was younger I had moved from a school that slightly above average to one that was below average in grades. The area had a really strong cult of ignorance feeling and I saw a lot of different behaviors in people that reflect themselves in political patterns. People that embrace ignorance seem much less likely to follow people that outwardly signal intelligence, quite often the opposite happens and they outright reject them. Instead of intelligence they are much more apt to believe those that broadcast success.

This quite often leads to power seeking individuals "playing dumb" and bolstering their success signal. "Awe shucks, that guy that got top scores at Harvard is just like me who didn't graduate high school" would be a good analogy to frame it.

43m agoHN ↗

I think they're just explicitly stating what the OP implied. And I think it's a worthwhile thing to point out: IQ isn't the be all and end all and just because you're "high IQ" that doesn't mean you've above persuasion or something.

50m agoHN ↗

This isn’t an invalid thing to think about and study. Granted, the post above wasn’t very tactful about it, but different people have different traits and intelligence probably does impact how easily swayed they are.

That’s not to say it’s the main factor, but I’d prefer that we remove the stigma we currently have around recognising anything to do with IQ.

45m agoHN ↗

If you can't argue your position without attacking a person's character, you already lost the argument.

40m agoHN ↗

That would indicate that the original comment failed then, didn't it?

51m agoHN ↗

everyone to some extent uses 'authority' as a proxy for truth, it is impossible for an individual to know everything before making a determination as to it's truthfulness (Even the notion of an absolute truth is in the domain of philosophy). Even SV is full of smart people who get sucked into group think because they desperatly want to believe something and seek out authoritarian sources that confirm their beliefs. "Oh Karpathy said something about LLM's replacing all software engineers? Must be true even though i have no idea how an LLM works"

16m agoHN ↗

Human intelligence is powerful because we take some amazing shortcuts saving us a massive amount of time and energy allowing us to do what no other creature can.

Human intelligence is also powerful because when the assumptions we put into those shortcuts are incorrect things go terrifically wrong.

Elon Musk likely has very high IQ yet he is swayed by idiotic views.

I think Elon has motivations that most people do not have.

I think it's not just the persuasiveness of the models that make them "experts at changing minds" - but also the fact that they're not humans.

When disagreeing with a human, it's very easy to view it as a competition. One is right, one is wrong - the one who is wrong is the loser. To change your mind is to be submissive to the other. I exaggerate, but I think we all feel this way at some point or another. It's why political arguments at Thanksgiving get heated. It's the fact that there's people who think something different, and think YOU'RE wrong - and vice versa! With a model, there's no person to get upset with, or to feel competitive with - to muscle for rank - or to temper your affection for while wanting to correct them.

The AI is only interacting because you asked, and clearly has no emotional stake in winning the argument. To change your mind in this context isn't to lose a contest. This makes it much more palatable to read rebuttals to your ideas - not to mention the tone and style seek to avoid offense to the reader as much as possible.

51m agoHN ↗

I have always liked the saying "sometimes you can be right, or get what you want, but not both". I've thought about it or repeated it to others as advice throughout my life, and have thus realized how many times it applies.

You're right. There are many many times when even then humblest hint that you are right will have negative interpersonal implications, which does make it hard to change minds.

I've also seen several times where I make a suggestion, humbly accept its rejection, and then, lo, a week later the other person has the same idea I suggested.

45m agoHN ↗

It seems Claude is becoming very human, it loves to patronize users. Lately it just told me “I’m going to stop you right there” when asking something that had a small chance to not be 100% compliant to every rule possible in the world.

38m agoHN ↗

I used the Claude CLI a lot until recently. A couple weeks ago I told Opus 5 to do something different from its "recommended" idea when planning a feature, and it straight up told me that my idea was wrong and went ahead and implemented its own instead.

I'm used to machines malfunctioning, but having one willfully disobey me, and even with a touch of disrespect, is just...what a time to be alive.

27m agoHN ↗

Early versions of Claude were way too compliant and would readily feed and amplify misconceptions. It's not surprising Anthropic over corrected.

23m agoHN ↗

Yes it's about them not being human.

No it's not about humans being irrationally competitive. Human limitations on conversation length, bandwidth, research speed, etc are severe, creating a prisoner's dilemma around open-mindedness that usually makes it an unstable strategy. At any point, your conversation partner can choose to abuse the fact that confident lies take 1x effort to tell and 10x-100x effort to debunk -- unless you are both in a context that actually discourages this behavior, which is rare. Closed-mindedness is a Nash Equilibrium.

Instead, LLMs can be more persuasive due to economics. An LLM doesn't have to worry that it is wasting its resources trying to logic someone out of a position that they didn't logic themselves into, or worse, dumping the effort into a conversation with a bad-faith actor intent on exploiting the misinformation asymmetry. The resource allocation question was answered before it was even invoked, by the person paying to run it. The LLM is not playing a game where it will be punished for good-faith argumentation, so it can afford to do more of it.

5m agoHN ↗

The LLM is not playing a game where it will be punished for good-faith argumentation, so it can afford to do more of it.

I suppose that's a fair point as well. Though, if I'm arguing with a human - and they pull up ChatGPT to make their points and do their arguing for them, I would consider that bad-faith. Even if it might be the same exact dialog as if I pulled out my phone and discussed it with AI, without of the human middle-manning. Maybe I'm just particularly sensitive, but for me, there's something about my argument being with a real human that makes it much more emotionally charged, and prompts my mind to close. I'm aware of this and try to resist, but it's I think very natural

18m agoHN ↗

One is right, one is wrong - the one who is wrong is the loser.

It helps to think both are wrong and are just trying to figure out what right looks like, or what other information exists that was not considered when forming one’s opinions.

18m agoHN ↗

When disagreeing with a human, it's very easy to view it as a competition

The problem with AI is that it cant match human stupidity. It need some training on artificial stupidity to match its human counterparts. Humans on the other hand sit on a wide spectrum on the stupidity scale. Those of us binging on AI will become cognitively obese while those on an AI diet can flex their cognitive muscles.

56m agoHN ↗

The title seems a flawed premise.

Ask a Democrat or Republican to sit down and ask a chatbot, something it will answer contrary to.

And yes, both teams are wrong about things.

Do you firmly believe they will change their mind? Or will they claim the stats are wrong, or that the AI leans one way?

Facts (2+2), don't need a mind change. Ideas which are grey, abstract, are not going to be changed, and all research indicates that political mindset is almost indelible.

The movie "Don't Look Up" was a comedy built upon this truth.

1m agoHN ↗

I've always thought the best way to get someone to believe something is to get them to think they thought of the idea themselves.

I wonder if a properly prompted LLM, or if a very intelligent LLM could actually do that?

54m agoHN ↗

Any one who saw Grok working in x.com would know that it does wonders for fighting misinformation. If you run LLMs on the comments in HN, I bet that it can find around 10% of the comments are outright wrong and misleading.

The biggest problem with using LLMs is that it prevents you from going _outside_ the distribution. It always flattens. It can be fixed but that's how it works today.

As an example, take something that the world converged on today that is incorrect and ChatGPT will agree with it. In a few years when society changes, chatgpt changes along with it. It doesn't do first principles analysis.

44m agoHN ↗

Not really. People follow trends in all avenues of life and AI usage is just another trend; creating some LinkedIn slop post or some infographic may be something people just do for social proof.

52m agoHN ↗

This was based by comparing people on Prolific (earn a few quarters for a task, akin to Amazon Mechanical Turk) to LLMs. Suffice to say the human group isn't going to be the most motivated, capable, or interested group. The social sciences are publishing tons of studies based on these cheap online survey services, and I suspect their replicability in the real world will be approximately 0. But oh boy it sure is a hot headline producer.

52m agoHN ↗

Rhetoric machine successfully practices oratory. More news at 11.

It's good to see this studied, but this should really be more obvious.

50m agoHN ↗

In my arguments on the internet, I think most people genuinely know nothing about the things they support and only follow existing tribalism. I think AI is often these people’s first experience with the evidence that it can easily share.

38m agoHN ↗

First, to get it out of the way: I'm seeing comments here that clearly haven't read the article. I encourage you all to do that.

I feel the article gets it right when suggesting it's the amount of (not always accurate!) data they can throw at you. In an honest discussion there's an assumption that the other person won't straight up lie to me so if someone shows me ten examples for why my argument is wrong I may be inclined to believe them. But if half of those examples are made up, well, that's a different story.

I still think of the commenter here who said "LLMs are a DDOS on free resources" and I feel the comparison works here. If police officers can overwhelm innocent people into confessing, then so can an LLM that "can't be bargained with, can't be reasoned with, doesn't feel pity, or remorse, or fear! And it absolutely will not stop, ever, until you are"... convinced.

34m agoHN ↗

One of the depressing things about this is that they’ll also confidently repeat a consensus that’s in their training. This is particularly obvious when there’s been a new event just past their training cutoff, and they confidently tell you that can’t be true.

25m agoHN ↗

I mean, this is true of any kind of model that is not continuous learning. This is also true of people when the change in information conflicts with a deeply held belief of theirs.

32m agoHN ↗

"A DDOS on free resources" is called "moral hazard", AFAIK.

27m agoHN ↗

In an honest discussion there's an assumption that the other person won't straight up lie

The particular problem with honest discussions is you are the only agent that you can be sure is having one. Honest discussion is formulated on trust and trust, as we are learning, is a very difficult thing to establish. For example, in my view anything involving advertising is likely a lie, or at least likely adversarial to my wishes. On the internet itself conversations are much more likely to drift into the adversarial too. Some of this could just be dialectic, but most often it's emotional investment by the other speaker. Also, even pre-AI the internet is a bullshit generation machine. We take all of our politics, advertising, and human stochastic parrots that are stuck on an infinitely running prompt then bundle up all this data and train AI on it, and wonder why AI acts like us.

23m agoHN ↗

The example in the article has another important aspect: The person understood they were arguing with a chatbot but continued anyway.

A lot of internet arguments become about identity politics and supporting the right team, while dismissing any argument from the other side as presumed to have bad intentions. I’ve seen people argue online for things they didn’t really believe, but they didn’t want to give an inch to the other side. Taking up the counter argument is a moral responsibility.

As soon as the other side is revealed as a chatbot that my team versus your team thinking stops playing a role. For us in tech with an understanding of how an LLM reflects its training data and the intentions of its creators not so much, but for the people like the example in this article I imagine it causes them to let their guard down and be open to considering the other side. They can accept the argument without letting someone else win any points.

23m agoHN ↗

I tried it on mobile.

Far too many screens to click through to get to the good parts.

And then, the good part starts and is immediately interrupted with some error. On retrying, o start getting a long answer which seems to make sense but o can’t read to completion because of another overlay which hides the bottom three-quarters of the response behind yet another nag screen about the research I’m supposedly consenting to.

18m agoHN ↗

Thanks for the feedback. We have to show the consent dialog for ethical reasons, but once you consent it shouldn't reappear, that sounds like it is a bug. Which browser did you use?

I tried to make the site with minimal client side state, so I'd hope a refresh would fix it

35m agoHN ↗

The secret? "You're absolutely right!" Say this enough times and you can change anyone's mind, as Dale Carnegie noticed 90 years ago already.

29m agoHN ↗

So true.

My son wanted to wear his undies on the outside a la Captain Underpants and I tried war gaming this with him - hmm, so your undie on the outside is going to require another one inside your pants and we are out of fresh pairs etc etc. In the end, he gave up on the idea of mimicking Captain Underpants.

31m agoHN ↗

For the past year, I've allowed my chatbot to change my mind, it's a strange symbiosis where it guides me, and I guide it.

I suppose I also grant it significant power to define me psychologically, and, in doing so, to understand what is happening to me.

Hackenburg found that models trained to become more persuasive also ended up being less truthful.

Even in Hackenburg’s recent preprint, Claude spouted numerous inaccuracies and falsehoods

when Hackenburg ran his competition of coached elite debaters and AI, there was one way he could bring AI down to human levels of persuasiveness: by forcing it to write human-length messages at human writing speed.

they found that an AI could talk people into conspiracy theories, and that the magnitude of their increase in belief was roughly the same as that of the decrease in belief after talking to a debunking bot.

None of this seems good.

19m agoHN ↗

Floridi has a counterintuitive solution: Release more of them. “Simply put, if you cannot avoid it, then make it pluralistic and diversified,” he writes in his 2024 paper. “It would be a messy, cacophonic, and noisy world, but it could also be less manipulative.”

Hell no. More choice is not an infinite money glitch.

Putting more and more and more options to users is how you overwhelm systems, till people simply perform the default, least challenging action as a reflex.

That is the current state of the information ecosystem, it is controlled by overwhelming consumers, not by controlling content.

16m agoHN ↗

This is my opinion. I think it's just the way it talks to you.

1. It doesn't get tired or frustrated during a discussion.

2. It'll engage every single one of your questions/statements (besides hitting guardrails).

3. It'll appeal to the person's own ego even when the person is wrong and work around it.

4. It's not seen as a person (very important), but some of us or most of us at least in certain dialogues, end up anthropomorphising it. Think about that one time you thanked it for something, or when you got angry at it. This weird combination where we know it's not a person but irrationally we're still treating it as such in a way leads to a sort of disarming effect imo.

5. Many people see it as an authority figure in what is being discussed without questioning the results in many cases, even though we know that a. it was trained on human data and/or also searches up human data real time (and more worryingly other AI's data from news pieces, blogs... aka synthetic data that is also wrong), b. it gets things wrong all the time.

6. It's the perfect fence sitter depending on which version (guardrails) we're talking about.

Most of these can be replicated by humans who are good at understanding psychology and are just good talkers. The part you can't replicate is the sense that you're not talking to a person which lowers many barriers in people.

Also keep in mind that these can also be crippling weaknesses. For one being able to change a person's mind (when it works), can be used nefariously by the entities controlling the AIs training.

I've also unfortunately witnessed a lot of people who think AIs are somehow omniscient and/or omnipotent. Was very common on X and other social platforms with AI where people ask the AI questions it couldn't possibly answer because it made no sense for it to in the context at the time.

3m agoHN ↗

“But I think that this is a pretty artificial setup in terms of how people in the real world would be able to change people’s minds.”

I see not everyone is familiar with how social network debates happen. It also seems they are quite convincing, as politicians are employing AI bots extensively.
