Propaganda

Misleading the human brain/mind is very easy. Notice how easy it is in the optical illusions below. Now imagine how easy it would be to create a logical illusion for each picture. We experience illusions of logic all the time - when we watch a commercial, or when a politician opens his mouth.

Something is surrounded by smaller things to make it look bigger, or larger things to make it look smaller. 

Facts are exaggerated to make something appear more or less than it actually is.

Our perception of the true nature of things is controlled by who ever designs the system, or reports events.

It's hard to see what's really going on when facts are mixed with misinformation.

Select facts are presented in a way to suggest something that didn't happen.
