Researchers believe they have identified the prime driver for a startling rise in the number of people who think the Earth is flat: Google’s video-sharing site, YouTube.
Their suspicion was raised when they attended the world’s largest gatherings of Flat Earthers at the movement’s annual conference in Raleigh, North Carolina, in 2017, and then in Denver, Colorado, last year.
Interviews with 30 attendees revealed a pattern in the stories people told about how they came to be convinced that the Earth was not a large round rock spinning through space but a large flat disc doing much the same thing.
Of the 30, all but one said they had not considered the Earth to be flat two years ago but changed their minds after watching videos promoting conspiracy theories on YouTube. “The only person who didn’t say this was there with his daughter and his son-in-law and they had seen it on YouTube and told him about it,” said Asheley Landrum, who led the research at Texas Tech University.
The interviews revealed that most had been watching videos about other conspiracies, with alternative takes on 9/11, the Sandy Hook school shooting and whether Nasa really went to the moon, when YouTube offered up Flat Earth videos for them to watch next.
Some said they watched the videos only in order to debunk them but soon found themselves won over by the material.
Landrum said one of the most popular Flat Earth videos, “200 proofs Earth is not a spinning ball” appears to be effective because it offers arguments that appeal to so many mindsets, from biblical literalists and conspiracy theorists to those of a more scientific bent.
One way or another, the interviewees found themselves believers and before long were asking “where is the curve?” and “why is the horizon always at eye level?”
