Big Tech companies Google and Facebook have enormous power to shift opinions and votes by manipulating content you see on their devices – without you knowing it.

That’s the finding of Dr. Robert Epstein, a senior research psychologist at the American Institute for Behavioral Research and Technology in California.

He calculated that if all the Silicon Valley companies pushed in the same direction, they could easily shift 15 million votes. That means they decide who the next President will be, Epstein told Epoch Times, a conservative online news outlet.

Epstein’s team set out “to determine what the big tech companies were showing people in the days leading up to the 2016, 2018, and now the 2020 election.”

They recruited “a diverse group of 733 registered voters, Republicans, Democrats and independents from critical battleground states Arizona, Florida and North Carolina.”

The team used special software to track voters’ searches on Google, Bing and Yahoo to see all election-related activities.

Epstein said that during the week of October 26 only the liberals received reminders to vote on Google’s home page.

Among those who identified themselves as conservative, “not a single person saw that reminder on the homepage,” he said.

“If you’re supporting one candidate, you want to get those voters off of their sofas if they haven’t yet voted by mail.

“Secondly, you want to discourage supporters of the candidate you oppose from voting, to keep those people home.”

To influence people who are still undecided, “you’re going to apply the most pressure … to try to nudge those undecided voters.

“Normally in a close election, those people decide who wins,” he said.

Google’s home page is seen in the United States 500 million times a day.

If that kind of reminder was being used systematically over time, it affected more than who voted on election day.

It affected who sent in mail-in votes, it affected who registered to vote,” Epstein said.
