In the United States' current polarized political environment, the constant publishing of articles with vehemently opposing arguments has made it almost impossible for Google to rank information properly.
So says billionaire Eric Schmidt, Chairman of Google's parent company, Alphabet, speaking at the Halifax International Security Forum on Saturday.
"Let's say that this group believes Fact A and this group believes Fact B and you passionately disagree with each other and you are all publishing and writing about it and so forth and so on. It is very difficult for us to understand truth," says Schmidt, referring to the search engine's algorithmic capabilities.
"So when it gets to a contest of Group A versus Group B — you can imagine what I am talking about — it is difficult for us to sort out which rank, A or B, is higher," Schmidt says.
Ranking is the holy grail for Google. And when topics have more consensus, Schmidt is confident in the algorithm's ability to lower the rank of information that is repetitive, exploitative or false. In cases of greater consensus, when the search turns up a piece of incorrect or unreliable information, it is a problem that Google should be able to address by tweaking the algorithm, he says.
"I view those things as bugs as a computer scientist, so if you are manipulating the information and then our system is not doing a good enough job of properly ranking it ... as a computer scientist, I can tell you, this stuff can be detected," says Schmidt.
