>>26Wikipedia can be trusted on topics which don't have a controversial nature such as "proton decay" or "float.h".
But once there is agenda the article cannot be relied on because there are factions which benefit from editing the article to promote their own agenda.
Ask yourself "What would this article look if i wanted to introduce bias towards a viewpoint opposite of the article viewpoint", and if there are major changes in text the article is probably already reflecting such a biased viewpoint.
