Survey: Two-thirds of millennials are certain the earth is round, the rest say it might be flat

Only two-thirds of millennials fully believe that the Earth is round, according to a study conducted by the British firm YouGov. The rest are open to the possibility that we’re living on a flat planet. Or, they aren’t quite sure.

Under the study, a total of 8,215 American millennials and other age groups were asked a series of questions about whether they believe the world is round or flat.

Here’s how they responded:

• I have always believed the world is round: 66 percent.
• I always thought the world is round, but more recently I am skeptical/have doubts: 9 percent.
• I always thought the world is flat, but more recently I am skeptical/have doubts: 5 percent.
• I have always believed the world is flat: 4 percent.
• Other/Not sure: 16 percent.

What about other adults?

Overall, an overwhelming majority of Americans — 84 percent — believe the Earth is round, the study found. But at least 5 percent said they used to believe that, but now have doubts and question whether the Earth is actually flat.

Americans who are older and hail from higher income brackets are less likely to believe in flat Earth theories, the study shows.

Seventy-nine percent of Americans earning less than $40,000 a year said the have always believed the Earth is round. That compares to 87 percent in the $40k to $80k income bracket. Ninety-two percent of people earning above $80,000 have always believed the Earth is round.

In recent years, the flat Earth theory has gained popularity and some celebrities and sports stars, such as rapper B.o.B and Celtics point guard Kyrie Irving have supported the movement.

Just two percent of all Americans resolutely say the Earth is flat.

Is there a spiritual link?

A majority of flat-Earthers call themselves spiritual, and claim scriptures support their belief. The study did not say which scriptures they believe provide proof of their claim.

Still, 52 percent of flat-Earthers call themselves “very religious.” That compares to just one-fifth of all Americans, the study stated.

According to YouGov, the results of the survey were weighted make it representative of the U.S. population.
