If you see a statement in a Wikipedia article that you are thinking of repeating or relying on for something, look first to see: does it cite a source? In this case it did not. In that case, stop here, you should probably not trust the statement. At least not if it's something that matters at all. If it does cite a source, then things are better, but there is still one more step before you should rely on it for anything more than barroom trivia (like, say, publishing an academic paper): you should probably take a glance at that source and see if it really says that.
Unfortunately that isn't enough, many sites copy unreferenced information from wikipedia without indicating their source. These sites can later end up being cited by wikipedia.
Especailly if you are new to a field it can be difficult to know who are the reputable sources and who are the not to reputable ones.
