There are a lot of “conspiracy theories” that are just true. Flat earth isn’t one of them. It’s not representative of the “conspiracy theories” that people would have reason to click.
Westerners “have more geology” than Easterners — mountains, deserts, volcanos, earthquakes — so they are more likely to click on something geology-related than New Jerseyans. More open spaces, more UFOs, so why not more queries about Flat Earth theories? They don’t necessarily believe the theories.
Who builds a computer that doesn't work in its environment?
Not to be a grammar cop, but it’s geography, not geology.
