To Google, that’s proof of its semantic search technology; to Googlers, it’s a convenience that saves them a few clicks. But to skeptics, of whom there are a growing number, it’s a looming public literacy threat — one that arguably dwarfs the recent revelations that Facebook’s trending topics are curated by humans.

“It undermines people’s ability to verify information and, ultimately, to develop well-informed opinions,” said Dario Taraborelli, head of research at the Wikimedia Foundation and a social computing researcher who studies knowledge production online. “And that is something I think we really need to study and process as a society.”

For Taraborelli, the primary issue with Google’s knowledge panels is that they aren’t terribly knowledgeable: They provide information but often leave out any context on where that information came from. That makes it difficult for readers to evaluate the accuracy of the statement or whether it’s the best and most complete of the available options.

They could just scroll down the page and click through some links, of course — but that becomes increasingly difficult as searchers migrate to voice and mobile, and as Google expands its rich-answer offerings without differentiating which programs those results source from.

There are “snippets,” for instance, which pull a portion of text from a cited webpage in response to a question like “how to lose weight.” There are maps, sourced from Google’s local search program, that will direct you to local businesses if you search something like “best pizza D.C.”

These are all concerning, as they algorithmically confer a lot of unearned authority. (There’s no indication as to what makes a restaurant the “best,” for instance — the locations proffered during a recent Google search wouldn’t make my top 10, let alone my top three.) But most pertinent to our interests are the modules and carousels linked to Google’s Knowledge Graph, an advanced database sourced largely from Wikipedia and constructed in part from user search patterns. According to a October 2015 analysis by the digital marketing firm Stone Temple Consulting, these knowledge panels, which are frequently unattributed, are one of the fastest growing types in Google’s arsenal.

In a 2012 blog post announcing the introduction of these modules, Google’s Amit Singhal rejoiced in the “critical first step” toward the future of search, an engine that “understands the world a bit more like people do.” Which is all well and good, until you get into subjects more complex than the current time in Timbuktu.

Mark Graham, a geographer at the Oxford Internet Institute, recently did just that: He and his colleague Heather Ford analyzed, in a paper published last month in the academic volume Code and the City, how the city of Jerusalem was represented both on Wikipedia and in Google knowledge panels. They found that while Wikipedia may explain the city’s contested geopolitical status in enormous depth — as of this writing, that portion runs to almost 1,500 words — the nuance was jettisoned completely when the article was deboned and ingested by Google.

“Google, through its data and algorithms, now controls how we interact with many facets of the cities we live in,” Graham warned. “So we should be asking whether we are happy ceding decisions about how we live our everyday lives to them.”

In fact, as Graham dug into other contested cities, he discovered that Google’s knowledge panels regularly, if inadvertently, make rather important decisions for us: Taiwan, you’ll remember, is described as if it were an independent nation, when only 22 countries actually recognize it as such. Meanwhile, Google corrects searches for “Londonderry,” Ireland’s fourth-largest city, to “Derry,” the (unofficial) term favored by Irish nationalists.

Since Google frequently does not cite its sources — a ploy, Taraborelli says, to make it seem more authoritative — there’s no way for users to double-check “answers” for bias or error, which doubtlessly exist.

In September, for instance, my colleagues in the Style section published a story on the peculiar fact that no one seems to know Hillary Clinton’s height — not even Google, which until recently listed it as 5-foot-7 in a prominent knowledge panel. That error appears to date back to an unsourced Wikipedia edit from 2007, which has since been debated and deleted by Wikipedians.

Now Googling Clinton’s height produces a mere rich-answer “snippet,” which incorrectly measures Clinton at “5 feet tall, maybe 5′ 2″.” But at least now you can click through to CelebHeights.com and see exactly what you’re dealing with.

In its defense, Google has made some changes to certain types of knowledge panels that suggest it’s aware of the whole sourcing thing. Medical queries now pull up proprietary editorial panels fact-checked by doctors at Google and the Mayo Clinic. And if you search for a food or recipe ingredient, the accompanying knowledge panel will also link you to the Agriculture Department’s database on food nutrition.

“Our goal is to be useful; we realize we’ll never be perfect, just as a person’s or library’s knowledge is never complete,” a Google spokesperson said in a statement. “We’re constantly working to improve search, and to make searching with Google easier and results more accurate for people.”

Unfortunately, as long as Google has a commercial interest in appearing omniscient, it probably won’t work to improve knowledge panel transparency. That burden will fall instead to people like Taraborelli and nonprofits like the Wikimedia Foundation, which is working on an open-license, machine-readable knowledge base that will both source all of its statements and accommodate conflicting sources. The hope is that Google will begin pulling from that database and citing its sources, instead of dumbing down Wikipedia.

Where history was once written by its victors, and later by its nerds, it’s now being shaped by its algorithms.
