Content: In this case when individuals are presented with ideas or data that contradict their beliefs, they refuse to "see" or recognize the information. If, despite their efforts, they have to confront these ideas, these individuals may try to discredit the source, or attribute the ideas to an incompetent, corrupt, or evil source. Sources of information that contradict 
	"approved ideas" are forbidden to be freely discussed and  considered. This approach has long been used in some conservative religions, and more 
	recently in right-wing political movements. You even find the suppression of "non 
	approved" ideas in some university classrooms where, according to the 
	definition of university, the open debate of ideas is supposed to be 
	encouraged. 3. Finally, there is selective recall. Simply put, 
some people tend to remember things that support their viewpoints and conveniently forget those that don't. For example, after a TV program is shown which contradicts some of 
their personal beliefs, they tend to remember only those facts that support their original beliefs. Or, 
they may remember "different facts," and feel that the program actually supported our views.
