In recent years, along with the fake news and other creatures enlightened by social networks, the world witnessed the emergence of a minority but noisy movement: that of those who believe that the Tierra it’s flat. Those who run into one of its members tend to oscillate between argued confrontation or resignation to the useless.
But how did it get here, 22 centuries after Greek astronomy ended -or so we thought- with all possible speculations? To understand those minds, the economist Jose Arroyo-Barriguetefrom the Comillas Pontifical University, decided to carry out a study among 1,200 students of engineering, business and social sciences from that house of studies, and high-income professionals, also university.

The results left him stunned: 17% disbelieved that the Earth was round. Although flat earthers turned out to be the least scientifically literate, they were the most supportive of their position. It’s called effect Dunning-Krugerand it is the cognitive bias by which the less we know about something, the more we think we know about it.
“Certain types of people need to feel special”, sums up the professor, who suggests that the same profile of some interviewees may have had an influence. With the fantasy of being socially above others, self-perceived the only true skepticsdetermined not to believe anything they can’t prove on their own.
They discovered a new ‘moon’ that revolves around the Earth
They might be surprised to see that, in fact, the proof of the earth’s curvature is at your fingertips. It is enough to observe a ship that is lost on the horizon. First the hull disappears and then the mast; If the Earth were flat, the image would be smaller, but it would always look complete.
In addition to being directly visible on some transatlantic flights, the curvature can also be verified during a lunar eclipse, when the Earth casts its round shadow on the Luna. For those who continue to doubt, there remains a final obviousness: if the Earth were a plane, and not a sphere that rotates hiding the Sol at the end of the day, the night would simply not exist.
