You don't need to vandalize Wikipedia to get this kind of thing to work.
Back in September 2024 I named a whale "Teresa T" with just a blog entry and a YouTube video caption: https://simonwillison.net/2024/Sep/8/teresa-t-whale-pillar-p...
(For a few glorious weeks if you asked any search-enabled LLM, including Google search previews, for the name of the whale in the Half Moon Bay harbor it confidently replied Teresa T)

This post has managed to “confuse” Google about the reverse question as well (“who named teresa t whale”):
The humpback whale known as "Teresa T" was named by Simon Willison in September 2024. Background: The juvenile humpback whale was frequently spotted in Pillar Point Harbor near Half Moon Bay, California. Method: Willison gave the whale its name through a blog entry and a YouTube video caption. Significance: The naming was a playful act, which Willison described as a way to create a "championship that doesn't exist" through online documentation.
[…]
Even with no context most humans would see that the quoted significance makes no sense.

That is some serious Gell-Mann-type amnesia. You’re trusting LLM models to give you accurate information about a subject we’ve already established (and are only talking about because) they can’t be trusted on.
“Widely referenced” is a common term which LLMs obviously pick up. Them outputting those words has no bearing on the truth and says nothing about the “popularity and the ripple effects of [Simon’s] posts”.

I mean, the name of that whale is now Teresa T. You gave it that name.
latexr28 minutes ago
And your name is now Berningular Farshthruster III. I gave you that name.
Which is, of course, silly. It is a name for you, just like Teresa T is a name for the whale, but it’s not your/their name, just like the RRS Sir David Attenborough is not named Boaty McBoatface (to the chagrin of most). Simon does not have the authority to unilaterally¹ name the whale (which is why the exercise makes sense).
¹ Important point. If the name started being recognised and used by consensus of those with the purview to do so (much like the thagomizer²), then Simon would have named the whale, but it would only become its name at that point.

It's an odd thing here, because I don't really understand why this is LLM-specific at all. If someone came up to me and asked "who's the 6 Nimmt world champion?" I'd google it and probably find the same result, and have no reason not to believe it. I mean, for all I know the game is being made up too, though it has more sources at least.
latexr14 minutes ago
> I'd google it and probably find the same result, and have no reason not to believe it.
Have you truly looked at the website?
I’d say there’s obvious reason to not believe it, or at least check another source. The website just seems fishy. Why would a website exist for just that one post? Sure, they could’ve made the website more believable, but that takes more effort and has more chances for something to jump out at you.
And therein lies a major difference between searching the web and asking an LLM. When doing the former, you can pick up on clues regarding what to trust. For example, a website you’ve visited often and has proven reliable will be more trustworthy to you than one you’ve never been to before. When asking an LLM, every piece of information is provided in the same interface, with the same authoritative certainty. You lose a major important signal.

It is not LLM specific. The conclusion of the post states
> The web was already being poisoned for search and link ranking long before LLMs existed.
But it continues

So it's a shift from trust Google to trust the AI, which might be more insidious or not, depends on the individual attitude of each of us.
bambax3 hours ago
It's a shift but it's a little worse. Checking/auditing search results is easier and more ingrained; even if many people don't do it, everyone has been hit by spam at some point, everyone knows it exists.
LLMs are the same thing but have an air of authority about them that a web search lacks, at least for now.
teifereran hour ago
To me that's the opposite. Whatever an LLM gives me, I view with skepticism. If I google sth then I quickly get a sense of how much I can trust it and what the BS factor is. I can refine my view in either cae, but my a priori trust with an LLM is much lower.
Maybe we just need to work on training the general population to have a similar bias. (It will be harder than it sounds. Unbelievable amounts of capital are being bet on this not happening.)
bambax37 minutes ago
Yes, it's the same for me, but we're not representative of most people I'm afraid.
SchemaLoad10 hours ago
The difference imo is removing the information from the source. Previously you'd use the source of the information to gauge how much you trust it. If it's a reddit post or a no name website you'd likely be skeptical if it doesn't seem backed up by better sources. But now the info is coming from an LLM that you generally trust to be knowledgeable. And the language it uses backs up this feeling.
The OP post is highlighting how incredibly easy it is for a very small amount of information on the web to completely dictate the output of the LLM in to saying whatever you want.

In that case most of the mitigations listed by the author don't help though (e.g. surfacing the source). That's also no different than traditional works with citations (be it Youtube videos or peer-reviewed academic papers), where anybody rarely verifies what's written in the cited sources.
The only real alternatives would be:
- Kicking off a deep research-like investigation for each simple query
- Introducing a trusted middleman for sources, significantly cutting down the available information (e.g. restricting Wikipedia to locked-down/moderated pages)
- Not having any information at all, as at some point you can rarely every verify anything depending on how hard your definition of "verify" is
locallost4 hours ago
You would also find other results (this assumes what you're searching for is not a random made up thing). The issue with LLMs is IMHO bigger because it will give you answers as a matter of fact without any other consideration.

The key to successful poisoning attacks is to introduce brand new information that doesn't directly contradict other training data. It's much easier to convince the LLMs that you're the king of a fictional Mapupu kingdom than the president of the United States.
So this means that for bad actors it's more efficient to manufacture brand new fake stories instead of trying to distort the real ones. Don't produce fake articles absolving yourself of a crime, instead produce fake articles accusing your opponent of 100 different things. Then people will fact-check the accusations using LLMs, and since all the sources mentioning those accusations are controlled by you, the LLMs will confirm them.

This is sort of why "brand" matters; it provides a source of trust.
Encyclopedia Britannica used to be that source of 'facts'. Then it became whatever page-rank told you. Eventually SEO optimization ruined that.
News stories are the same thing. For certain groups, they have their 'independent' publication whose reporting they trust.

One of the problems with labelling automation as AI.
People think that whatever information an "AI" spits out has gone through a round of critical thinking which enhances the trust value of that information.
The early LLM's using groomed data may have had such critical thinking somewhere in the pipeline. So it was already not really trustworthy.
And now? Using agents to search the internet for you?...
Garbage in, garbage out still applies in computing as ever.

Most of the popular discourse around AI is still at the level of, "Don't trust the AI, trust the sources!" When it gets to the point where even the sources of simple facts are untrustworthy, the average person just trying to learn some trivia about the world is doomed.
Doesn't help that AI media literacy is so primitive compared to how intelligent the models are generally. We're in a marginally better place than we were back when chatbots didn't cite anything at all, but duplicated Wikipedia citations back to a single source about a supposedly global event is just embarrassing. By default, I feel citations and epistemological qualifications should be explicit, front-and-center, and subject to introspection, not implicit and confined to tiny little opaque buttons as an afterthought.
amiga38613 hours ago
Wikipedia calls this https://en.wikipedia.org/wiki/Citogenesis (after XKCD coined it).
You can expect the spicy autocomplete to feed you flattering bullshit. It may cite Wikipedia (it shouldn't), but you should go check out those citations, and validate the claims yourself. It's the least you can do.
And if the cited source is Wikipedia... check Wikipedia's sources too. Wikipedians try their best to provide you with reliable sources for the claims in their articles (oh who am I trying to kid? They pick their favourite sources that affirm their beliefs, and contending editors remove them for no good reason, and eventually the only thing that accrues is things that the factions agree on, or at least what ArbCom has demanded they stop fighting over).
I guess what I'm trying to say is: don't rely on that authoritative-sounding tone that Wikipedia uses (or that AI bots use, or that I'm using right now). It's a rhetorical trick that short-circuits your reasoning. Verify claims with care.
Also check the Talk page, you often find all kinds of shenanigans called out there.

Perhaps my favorite example of a citogenesis-like process is the legendary arcade game Polybius, which originated as an entry on some German guy's web compendium of arcade games (coinop.org), perhaps as a "paper town", or fake entry that acts as a copyright canary when duplicated elsewhere. Gamer news and special-interest blogs and sites, and even print publications like GamePro picked it up, and I think it was even listed on Wikipedia as an urban legend whose actual existence was unknown. Then the retrogaming YouTuber Ahoy did an in-depth documentary (https://m.youtube.com/watch?v=_7X6Yeydgyg) which concluded that Polybius didn't exist and was never even mentioned before the aforementioned coinop.org reference and, for me anyway, that settled it. Polybius, in its urban legend form, never existed.

Pretty much boils down to lying.
Since we've been kids we've been taught, hopefully, that lying is bad.
Society though normalize it :
- advertisement is pretty much always wrong (to the point of having laws in Japan about food packaging, France about modeling, etc) and the deception is the message
- entrepreneurs promises, nobody reach the goals set to VCs, it's always a lower number no matter the KPI. See https://elonmusk.today where the wealthiest man on Earth, ever, keeps on lying pretty much daily.
- political promises, no need to even give examples of that because it's just pervasive.
so... yeah, we keep on telling our kids "Do as I say, not as I do." then we somehow keep on being shocked that the practice of lying is pretty much happening in every corner of our society.
