Within the case of AI Overviews’ suggestion of a pizza recipe that accommodates glue—drawing from a joke submit on Reddit—it’s possible that the submit appeared related to the consumer’s unique question about cheese not sticking to pizza, however one thing went improper within the retrieval course of, says Shah. “Simply because it’s related doesn’t imply it’s proper, and the technology a part of the method doesn’t query that,” he says.
Equally, if a RAG system comes throughout conflicting data, like a coverage handbook and an up to date model of the identical handbook, it’s unable to work out which model to attract its response from. As an alternative, it could mix data from each to create a probably deceptive reply.
“The big language mannequin generates fluent language based mostly on the supplied sources, however fluent language is just not the identical as appropriate data,” says Suzan Verberne, a professor at Leiden College who makes a speciality of natural-language processing.
The extra particular a subject is, the upper the prospect of misinformation in a big language mannequin’s output, she says, including: “This can be a drawback within the medical area, but in addition schooling and science.”
In keeping with the Google spokesperson, in lots of instances when AI Overviews returns incorrect solutions it’s as a result of there’s not a number of high-quality data obtainable on the internet to point out for the question—or as a result of the question most carefully matches satirical websites or joke posts.
The spokesperson says the overwhelming majority of AI Overviews present high-quality data and that lots of the examples of unhealthy solutions have been in response to unusual queries, including that AI Overviews containing probably dangerous, obscene, or in any other case unacceptable content material got here up in response to lower than one in each 7 million distinctive queries.

Though the pizza glue blunder is an efficient instance of a case the place AI Overviews pointed to an unreliable supply, the system may generate misinformation from factually appropriate sources.

Whereas Barack Obama is just not Muslim, making AI Overviews’ response improper, it drew its data from a chapter in an educational e book titled Barack Hussein Obama: America’s First Muslim President? So not solely did the AI system miss the complete level of the essay, it interpreted it within the actual reverse of the meant means, says Mitchell. “There’s a number of issues right here for the AI; one is discovering a very good supply that’s not a joke, however one other is deciphering what the supply is saying accurately,” she provides. “That is one thing that AI methods have bother doing, and it’s essential to notice that even when it does get a very good supply, it might nonetheless make errors.”
