A citation isn't a statement of fact in a general sense anyway. A bit of information from a study, means that under these very specific set of conditions, this happened. Your ability to generalise that to a 'fact' which is true in all cases is pretty limited. All citations do is add support for or against an argument, they aren't statements of fact.
