It is my goal to unbias articles in Wikipedia. The methods I use are the following:
Monitor "ownership" or attempted hijacking of articles, such as is seen in the Circumcision article, where a single gay man spends his days biasing the article toward a single view. This is a simple metric which can be monitored through a Wikipedia's article history.
Monitor diction or word choice which produces bias and slights an article in one direction or another for reasons such as one's own personal opinion, colloquialism, prejudice. This does not mean merely specificity. Specificity and vagueness are two conflicting ideas which find their way into articles through use of diction, and, the opposite, maladiction. This aspect of the English language either defers concision (conciseness) or creates an undue amount of specificity.
