This is why we, humans, institucionalize schools and teachers, research and scientific development, trying to perpetuate knowledge and even improve it.
This is why there are scientists, universities, technology development, health and food improvement.
The stupid and ignorants are easy pray for any wrong information and manipulation, bad guys knows it, and use it for their own gain and profit.
It is no surprise why most of the world's population still poor, hungry and sick.
Lots of people do not have a minimum idea where North direction is, or even read a map on paper. Do you really expect them to have a 3D mental mechanic visualization capability to understand the universe, gravity, elliptic orbit, shadow projections, photons and radiation path and refraction, stars, space and time, etc? They have no idea even what "elliptic" means. They can not understand.
For those people, if you promise them "a diploma, or making part of a group" without needing to think, learn, use a calculator, study, etc, just by following you, and listening to you saying "believe me, I know it", they will follow you easy, they will pile up to share your "knowledge without efforts". That is how humanity is behaving for thousands of years. The worst atractors are the ones without any logical of scientific explanations, you just need to believe, and that's it. On purpose they don't explain by numbers just to have an easy escape route in case of any contesting. If you state your home has 2000 square feet facing north, it is better to have it right, somebody may prove you wrong and a liar. But if you say "my home is big, facing the wind"... you can always get rid of someone trying to prove you wrong. A nasty trick used by many crooks.
One of the best things I learn in life was that people are not the same. If you learn something a little more than your neighbor, congratulations, but you will be along with few ones in this universe. You can try to teach your neighbor, but don't expect that he will be capable to understand a single word you say, or worse, he may not even want to hear you. For lots of people, the act of "thinking" hurts, it is difficult, tiresome, even boring.
Science and experience proves that to build a bridge or a building you need to do a lot of calculations, it could not be done only by guessing and believing.
