Is Contrarian a Psychology Problem?
Some time ago a contrarian (a concept more usually found in literary or journalistic circles), in psychology would be called 'contra suggestive' or 'contra suggestible'. The two are, however, subtly different.  A contra suggestible person simply believes or does the opposite of something suggested by someone else. 

Being a contrarian on the other hand usually involves going against cherished societal beliefs, or against prevailing group norms, and can be related to iconoclasm. 

Contra-suggestibility (sometimes hyphenated) came out of the psychoanalitic literature, with all the fun and games that entails.
