I discussed this elsewhere, and someone else brought the subject up, but it got lost in the noise.
One of the fundamental problems of the Wikipedian editing model about people, though this extends further, is that the majority of editors are locked into using the Internet as its main resource.
This leads to a few biases:
* News driven agenda for articles. People are defined by their newsworthy events, rather than a rounded view of their life.
* News articles are of the time and there may not be a newsworthy need to re-visit the subject after the event (this is happening, we think because of... vs that happened and we now know that...).
* Important topics are discussed in terms of the newsworthy elements which tend to be the controversy of the subject. Again, a well rounded article, though acknowledging the elements of public interest, needs to take a rounded view of the subject matter.
* Qualified editors who have access to specialised sources may have their sourcing excluded as it is not generally available, therefore not verifiable.
* The Internet represents a dubious subset of all possible sources: potentially missing sound, copyrighted printed sources of high value; sources written to push an agenda; poor evaluation of the quality of sources: if a quality name can be introduced into the sourcing, little account is given to the type of source (e.g. WP:Verification looks to mainstream newspapers, without explaining the myriad of qualifications that need to be considered).
What this type of problem tells me is that the current Wikipedia can never expect to produce a reliable article because there is no process to address this, it is simply illogical to claim that a system not designed to produce the ideal article can magically be expected so to do by the simple application of many pairs of hands of people who have no specific knowledge of the subject, and who will only gain a consensus of a subject based on reviewing the common flawed sources of the Internet?
The main process that a real encyclopedia would use to solve these issues is the skill of the authors (a word that comes to mind is TRUSTWORTHY), but the Wikipedian model, especially through policy of NOR, denies that it is appropriate for editors to apply reasoning in their editing process - this being identified as original research or synthesis (albeit that the original reasoning for NOR was sound, the impact of extending this concept into an all-embracing solution to improper editing is flawed).
