Why Google Showed Capitalism in Search for Socialism and Racism

Google Search accused of political bias. Google explained why the results were shown, then removed them soon after.

Why Google Showed Capitalism in Search for Socialism and Racism

A former NYTimes reporter and novelist accused Google of having an ideological bias. He cited a search for “socialism and racism” that returns results that include “capitalism.” Google explained why this happened. Then days later the disputed search results changed and are no longer there.


Google’s search result for this search query has changed. The search results no longer includes results for capitalism.

According to Google, this wasn’t a manual change. It was part of changes that happen in the algorithm automatically.

Socialism and Racism

The search phrase “socialism and racism” also returns results for “capitalism.” Some took it as evidence that the search results have a leftist bias.

Here is the original tweet:

Some pointed out that DuckDuckGo and Bing don’t contain results for capitalism in a search about socialism and racism.

Google Explains Search Result

Google’s Search Liaison, Danny Sullivan, responded by tweeting an explanation why Google includes results for the word “capitalism” in a search for “socialism and racism.”

Danny responded in a tweet:

“By default, Google automatically looks for related words, often useful as creators might not use the same words as searchers. That’s what’s happening. The label is to explicitly alert searchers, in case they wish to restrict the expansion. More here:

Danny Sullivan then links to a graphic that shows how words used in a search query can be substituted with synonyms and related words while still conveying the same meaning.

That’s what “query expansion” is about, to find web pages that answer the question, whether or not they use the exact words in the search query.

It doesn’t matter if someone uses the word angler or fisherman, both words describe the same thing. By doing query expansion, Google can widen its search for the right answer.

In general this improves the search results.

But not in this case.

Many users on Twitter voiced their displeasure with search results that include the word, “capitalism” for a query that has nothing to do with capitalism.

Danny Sullivan answered the question from his official Google SearchLiaison Twitter account.


“When searching on Google, by default we automatically also search for any synonyms & related words to what was entered, as this is often helpful. Yesterday, our systems that do this raised concerns we were intentionally making some ideological statement. This was not the case…”

Followed by:

“If Google only returned documents that contained the exact words entered in a search, we would miss displaying relevant content. For example, “change” as used by a searcher might fail to match documents that talk about “replace” or “exchange” or “adjust” as written by a creator…”


“This type of query expansion happens regularly. But in some cases, we detect the top results returned may be further away in relationship to the original terms entered. In such cases, we automatically label that a broader expansion is happening & provide an override option….”

Google SearchLiaison then linked to the following examples:

Google then explained that the reason “capitalism” was included in a search that is about “socialism” is because the two words are “closely related.”

Some may arguably feel that capitalism and socialism are not closely related but rather broadly related. And for that reason, many users were unsatisfied by the search result that included capitalism.

Google explained further:

In the end, Google SearchLiaison implied the possiblity of using this feedback to improve.

Do Google Search Result Show a Leftist Bias?

Google SearchLiaison tweeted that they use feedback to improve their systems.

“Overall, these types of expansions are often useful for searches. However, we know they’re not always perfect. That’s why we notify when a broader one happens. And we use feedback as with this case to see if we can improve our automated systems further.”

Some are interpreting that the “Socialism and Racism” search result as evidence of a leftist bias from Google.

Google says it’s their query expansion algorithm that’s responsible for search results that feature the word capitalism in a search related to “socialism and racism,” not a political bias.
