Flat Earth Theory
Modern flat Earth societies consist of individuals who promote the idea that the Earth is flat rather than a sphere. Such groups date from the middle of the 20th century; some adherents are serious and some are not. Those who are serious are often motivated by pseudoscience or religious literalism.
Earth is not flat, by the way:
Flat Earthers fall into two categories:
1. People with very low intelligence in areas of critical thinking, logic, problem solving, etc. This group comprises the vast majority of flat earthers.
2. People with at least a modicum of intelligence who do not actually believe the “theory” of flat earth but stand to profit in some way financially or just like the attention. This is a much smaller percentage of total “believers”.
