Google's Sundar Pichai explains to Congress why searching 'idiot' results in Donald Trump pictures
The House Judiciary Committee has questioned Google chief executive Sundar Pichai over why, when you search the word "idiot" in Google images, a picture of US President Donald Trump comes up.
"How does that happen? How does search work so that that would occur?" Democratic representative Zoe Lofgren asked.
Mr Pichai answered earnestly that Google stores billions of pages in its index, takes the keyword, matches it against the pages and then ranks them.
He said "things like relevance, freshness, popularity, how other people are using it" play a part in how items are ranked so that, at any given time, that rank will show the best results for the Google search.
"So it's not some little man sitting behind the curtain figuring out what we're going to show the users?" congresswoman Lofgren asked.
"[Instead it's a] compilation of what users are generating in trying to sort through that information?"
Mr Pichai answered: "Last year we saw over 3 trillion searches, so we don't manually intervene on any given search result."
Why was he even asked this?
In the past, Mr Trump has accused Google of rigging search results to suppress conservative viewpoints and highlight coverage from media that he says distribute "fake news".
In August, he tweeted:
Donald J. Trump
Google search results for “Trump News” shows only the viewing/reporting of Fake News Media. In other words, they have it RIGGED, for me & others, so that almost all stories & news is BAD. Fake CNN is prominent. Republican/Conservative & Fair Media is shut out. Illegal? 96% of....
....results on “Trump News” are from National Left-Wing Media, very dangerous. Google & others are suppressing voices of Conservatives and hiding information and news that is good. They are controlling what we can & cannot see. This is a very serious situation-will be addressed!
Google has denied any such bias, and while the question has dogged tech companies for years, there's no evidence of an anti-conservative or any other political tilt.
While a statement from Google at the time said search results are not dictated by a political agenda but are generated by algorithms which are constantly being improved, Mr Pichai told Congress on Tuesday "we don't participate in partisan activities".
"We engage with both campaigns. We support and sponsor debates on both sides of the aisle."
Top committee Democrat Jerrold Nadler called the notion of bias a "delusion" and a "right-wing conspiracy theory".
He said Tuesday's hearing was the committee's fourth to address the topic — and he suggested he would move on to other topics, like the spread of misinformation online and Russians' efforts to influence US elections online.
