TEHRAN (Press Shia) – Google CEO Sundar Pichai explained to Rep. Zoe Lofgren who asked why she gets pictures of US President Donald Trump when she searches for the word idiot as something that people are associating with that word.

In a House Judiciary Committee hearing on Tuesday, Google CEO Sundar Pichai was asked to explain why a Google image search for “idiot” turned up pictures of Donald Trump — and whether that was a case of intentional bias, according to the Verge.

The question came from Rep. Zoe Lofgren (D-CA), who was trying to refute the idea that Google is politically manipulating search results. “Right now, if you google the word ‘idiot’ under images, a picture of Donald Trump comes up. I just did that,” she said. “How would that happen?”

Pichai offered a long, general explanation of how Google search works:

Any time you type in a keyword, as Google we have gone out and crawled and stored copies of billions of (websites’) pages in our index. And we take the keyword and match it against their pages and rank them based on over 200 signals — things like relevance, freshness, popularity, how other people are using it. And based on that, at any given time, we try to rank and find the best search results for that query. And then we evaluate them with external raters, and they evaluate it to objective guidelines. And that’s how we make sure the process is working.

“So it’s not some little man sitting behind the curtain figuring out what we’re going to show the user?” Lofgren asked sarcastically.

“This is working at scale, and we don’t manually intervene on any particular search result,” replied Pichai.

News outlets reported on the Trump “idiot” results earlier this year. If you search the term now, in fact, you’ll mostly get pictures from stories explaining why it happened. It appeared to be the result of outside parties gaming Google’s search results, a well-known tactic known as “Google bombing.”

Trump isn’t the first president to get Google-bombed: in the mid-2000s, searches for “miserable failure” famously returned results about President George W. Bush. It can be a politicized (or just funny) extension of normal search engine optimization tactics.
