Why?

I'm trying to understand why something very straight forward can get so complicated. Is it because people only see what they are prepared to see.

We are limited not by our abilities but by our vision. Don't limit ourselves to fewer possibilities by the narrowness of our vision. Due to cognitive bias, these limitations may lead to the "bandwagon effect", the tendency to believe things because many other people believe the same. 

 

So a group of determined people could take advantage of this tendency to promote ideas that may lead to a wrong perception of the issues at stake. Once a bandwagon gets rolling, it can be hard to undo the damage. This happens a lot in our society...
