User:Titodutta/Essays/Self-contradictory reliable sources

We know one pillar of Wikipedia is Reliable Sources. In this essay we'll discuss on and try to make a list of some confused, self-contradictory reliable sources.

What not to add

 * We are not going to discuss on corporate, political influences on news media here. So, don't add such examples here. We can write a new essay on it.
 * This essay is not a comparison of different reliable sources (eg. Book B1 of Publisher P1 says this and Book B2 of Publisher P2 says completely different thing.) The contradiction must be in a single reliable source or books/articles written by same author or news articles published by same newspapers.
