Google has tried numerous ways to get ahead of fake news since the 2016 elections, but its ranking algorithm has trouble judging the truth when opposing groups support two different "facts".
Besides the Russian trolling during the elections, Google The problem of promoting misinformation arose after the recent mbadive shootings in the United States, since the trolls use the event to blame the opposite political ideologies.
According to Eric Schmidt, president of Google father Alphabet, these online skirmishes make it difficult for Google's ranking algorithm to separate the truth from the lie.
"Let's say that this group believes in fact A, and this group believes in fact B, and you are pbadionately at odds with one another and everyone publishes and writes about it, and so on. We understand truth, "said Schmidt at the International Security Forum in Halifax.
"When you come to a group A contest in front of group B, you can imagine what I'm talking about, it's difficult for us to determine which rank, A or B, is higher."
Schmidt said it was easier for Google's algorithm to handle false or unreliable information when there is a greater consensus, but it is more difficult to separate the truth from the wrong information when opinions are diametrically opposed.
He also pointed out the issue of the echo camera often badociated with Facebook and Twitter, whose algorithms use friends and followers to create a news channel.
"Until we decide collectively that occasionally someone not like you should be inserted into their database, which is a kind of social values, I think we're going to have this problem," he said.
In an August interview with Fast Company Schmidt discussed the threat of network propaganda sponsored by the state. He said that Alphabet underestimated the extent to which governments would use hacking to control the information space and since then has been very interested in misinformation and how it works.
The president of the Alphabet also doubted that artificial intelligence could "avoid bad things", even if the algorithms were essential to eliminate the trolls.
