The problems with Wikipedia

February 18th, 2007

Wikipedia is one of the most incredible developments that I’ve ever seen. An

encyclopedia that anyone can edit? Sounds like a fruitbat notion doomed to failure. But it’s worked.

Mostly.

There are a few fault points developing. And these may show the beginning of the end for Wikipedia as

we know it. A couple of examples:

Exhibit one – the ongoing webcomics war on wikipedia.

There have been a strange, ongoing series of fights in Wikipedia over the question of notability in Wikipedia.

The story in a nutshell (see Websnark for a few more examples.

) is that some of the Wikipedia editors are systematically deleting the articles for many web comics.

Now web comics are probably not a hugely broad phenomena, but they’re certainly pretty popular with

a large number of people (even if the proportion is small).

The argument for deleting is ‘notability’. The guidelines state that there

need to be multiple, non-trivial mentions in newspapers, magazines and so forth. Given that there is

little coverage of web comics outside of the community (which, of course, doesn’t count for this) then

it’s very hard for even a relatively famous web comic to qualify.

(I could, by the way, go on about the strange anti-democratic nature of requiring some media gatekepper

to decide what’s notable, but that’s not really the point).

The real problem I have with this is that the rules for websites don’t really match up with the rules for fiction.

There is, for instance a fairly long article on the Kobayashi Maru,

a fairly minor plot point from a Star Trek film. There are almost five hundred articles

on different Pokemon species. There are many pages of Harry Potter characters, including Sir Patricky Delaney-Podmore.

Personally I don’t object to any of these being included in the Wiki. They are, after all, of interest

to some people. But what I find deeply perplexing is the low standard for inclusion set here compared

to elsewhere. So long as an article is well written and encyclopedic, does it really matter how many people

it’s of interest to? Just hit ‘Random Page’ a dozen times in a row to see what kinds of things do

make the cut.

So, problem one: where do you draw the line about what to include, especially when you need lines that make

sense for both apples and oranges?

Exhibit two – Microsoft hiring someone to edit articles in their favour.

A brief blog-storm came up recently over Rick Jeliffe’s revelation that Microsoft had offered to pay him

for a few days work to correct entries on their OOXML file format. Microsoft was more or less asking

him to go and improve the articles, without any editorial control. And, by all accounts, the articles

were in a pretty bad state of anti-Microsoft hysteria (although Rick does not appear to be hugely

impartial in the ODF versus OOXML fight).

There are a bunch of questions about the ethics or otherwise of this. But the bigger issue is that

it’s pretty much impossible that a lot of companies are not actively out there doing exactly this

sort of thing with far less disclosure than we see here. It is pretty trivial, after all, to use

an anonymising web surfing service to disguise your point of origin. And with the number of fanboys

(and -girls) out there for pretty much anything these days (I’m looking at you, Nintendo and Sony!)

it would be very hard to tell for certain that a person was an actual company shill.

This is a very important issue for trust in the Wiki. A very wise person once described Wikipedia as

being:

a kind of quantum encyclopedia, where genuine data both exists and doesn’t exist depending on the precise moment I rely upon your discordant (…) mob for my information.

If you’ve got agents in the system trying to actively mislead this problem can become a lot worse.

The objective of ‘Neutral Point of View’ that Wikipedia espouses can help, but it’s very hard to

achieve in the real world. Sometimes even attempting to create balance can itself violate NPOV – for instance,

should pure creationist arguments be given equal time with evolutionary arguments? And if not, exactly

how much less should they get? ‘NPOV’ is a lovely ideal, but it’s not really practical.

Exhibit 3 – Wikipedia hates experts

This is a simple case – there’s an article on a fairly abstruse bit of theoretical philosophy. A genuine

expert in the subject (tenured, wrote one of the books the article refers to) comes along and make

some suggestions. But gets (effectively) jeered out of the room.

Under the Wikipedia model all input has equal weight. So if I go and edit articles on economics (with

a background of a degree and seven years work experience) I get the same weight as someone who

can barely remember high school economics. I was actually a bit involved in Wikipedia for a while,

but gave up because getting quality edits to stick was just too hard. The normal answer to this

is that the expert has an obligation to convince people, which is fine – no one should take

my word for it just because I say so. But on the other hand, these are complex areas, which can

takes years of study to understand fully. If I wanted to teach my subject to people I’d be at

university, and I’m not prepared to conduct a tutorial online just to improve an article on

Wikipedia – I just don’t care enough.

This problem is particularly acute in areas which appear to be accesible to lay persons – economics

is one case in point, philosophy is another. These are both complex subjects with a lot of theoretical

background to them, but there are also both subjects where a lot of people think they have all the

answers.

The requirement for citations helps a lot here, and things are a lot better than they were 12 months

ago. But in cases where there are two conflicting citations, how do you decide what version is right?

You need experts to make Wikipedia work, and Wikipedia makes it very hard to be an expert without

getting very cranky.

So what does all this mean?

The three examples here all about the ‘meta’ layer of Wikipedia, the governance mechanisms that make

the whole thing keep ticking over. I think these three examples are all signs that Wikipedia is not

scaling well. When you have an encyclopedia of a few thousand articles it’s easy for everyone to

build a common consensus across the whole system about the rules that apply. But when there are (as of

the most recent count) over 1.6 million articles it’s not longer possible for a single group of

people to look over them all. Instead you end up with a collection of overlapping communities within

different sections of the Wiki. But different communities end up with different rules and values,

even if they operate within a common set of formal, written rules.

The breadth of wikipedia makes abuse easier, makes policing it far more difficult.

Can Wikipedia survive? My guess is that it can’t, not in its current form. More formal governance

mechanisms will be needed, a greater distinction between the ‘live’ sections of the site and the

ones the public see by default, and more accountability for those people who work in the governance

structure.

I hope it does survive – I don’t think there’s a site (other than Google) that I use more frequently.


The best eight word summary of the Iraq war plan

February 15th, 2007

The US National Security Archive (not an official body)

has just obtained the PowerPoint briefing on the Iraq war plan from 2002.

There’s lots of great stuff in this, but I was particularly struck by one sentence from the

second slide in the pack

Thinking “outside the box”, but “inside a compartment”

When they come to write the book on this war, that should be the title…


Movie Review: The Last King of Scotland

February 15th, 2007

Last week we went to see The Last King of Scotland, the new

film based on the regime of Idi Amin.

The film (based on the book of the same name) is a fictionalised account of a doctor (Nicholas Garrigan, played by James McAvoy)

who falls in with the regime of Amin. But the centre of the film is Amin, played in what is probably

the performance of the decade by Forest Whitaker. It’s

a very difficult role to play – Amin must appear charismatic in order for us to understand how

Garrigan (and, indeed, Uganda) can be attracted to him in the first place. But he also has to have

the underlying evil of the man too. Anything other than a brilliant performance would have undermined

the whole film.

It’s not an easy movie to watch, and gets a little graphic at times. There are also a couple of small

stylistic missteps (in my opinion, at least) in the final third as Garrigan begins to realise what

situation he’s in. But overall this is a fantastic movie well worth seeing.
