Examine your memeplex

Basic definition of 'memeplex' from Wikipedia:

Much of the study of memes focuses on groups of memes called "memeplexes", "meme complexes" or "memecomplexes" — such as religious, biological organisms, cultural, or political doctrines and systems. Some selfish genes propagate more effectively together. Similarly some memes propagate more effectively together; they are called memeplexes. Examples are sets of beliefs like acupuncture and astrology, sets of traditions like Christmas celebrations, circumcision, languages, political ideologies, religions and scientific theories.

The enemy of the memeplex is called 'cognitive dissonance' - here is the basic definition of that from Wikipedia, again:

Cognitive dissonance is a psychological term describing the uncomfortable tension that may result from having two conflicting thoughts at the same time, or from engaging in behavior that conflicts with one's beliefs.

Cognitive dissonance can be good though, as it may force you to re-examine your beliefs. Then again, it could drive you insane.
