Statisticians Investigate Political Bias On Wikipedia

Hugh Pickens writes "The Global Economic Intersection reports on a project to statistically measure political bias on Wikipedia. The team first identified 1,000 political phrases based on the number of times these phrases appeared in the text of the 2005 Congressional Record and applied statistical methods to identify the phrases that separated Democratic representatives from Republican representatives, under the model that each group speaks to its respective constituents with a distinct set of coded language. Then the team identified 111,000 Wikipedia articles that include 'republican' or 'democrat' as keywords, and analyzed them to determine whether a given Wikipedia article used phrases favored more by Republican members or by Democratic members of Congress. The results may surprise you. 'The average old political article in Wikipedia leans Democratic' but gradually, Wikipedia's articles have lost the disproportionate use of Democratic phrases and moved to nearly equivalent use of words from both parties (PDF), akin to an NPOV [neutral point of view] on average. Interestingly, some articles have the expected political slant (civil rights tends Democrat; trade tends Republican), but at the same time many seemingly controversial topics, such as foreign policy, war and peace, and abortion have no net slant. 'Most articles arrive with a slant, and most articles change only mildly from their initial slant. The overall slant changes due to the entry of articles with opposite slants, leading toward neutrality for many topics, not necessarily within specific articles.'"

Equally biased != NPOV

One guy may say that the sun is green, the other guy may say it's purple. Having both of them in the same article does not make it neutral.

Would it kill you to read the paper?

We obtain a list of 111,216 articles. We then eliminate these articles that cover countries other than the United States.
[...]

For each of these articles, we construct a slant index by applying the methods and estimates developed by Gentzkow and Shapiro (2010), hereafter G&S. G&S select 1,000 phrases based on the number of times these phrases appear in the text of the 2005 Congressional Record, applying statistical methods to identify phrases that separate Democratic representatives from Republican representatives, under the model that each group speaks to its respective constituents with a distinct set of coded language. In brief, we ask whether a given Wikipedia article uses phrases favored more by Republican members or by Democratic members of Congress.

And the corresponding footnote:

The words “republican” and “democrat” do not appear exclusively in entries about United States politics. If a country name shows up in the title or category names, we then check whether the phrase “United States” or “America” shows up in the title or category names. If yes, we keep this article. Otherwise, we search the text for “United States” or “America.” If these phrases do not show up more than 3 times in the text, this article is dropped. This process keeps articles such as “Iraq War” but drop articles related to political parties in foreign countries.

Researchers do think of this stuff, you know.

Dangerous to Conclude this is "Slant"

[eldavojohn]

This is a neat study but I feel like the foundational assumptions are subjective and a little flawed.

(civil rights tends Democrat; trade tends Republican)

Could that be simply because Democrats invent/introduce/overuse new phrases and talking points for civil rights and Republicans invent/introduce/overuse new phrases and talking points for trade? For example, you'd probably hear Democrats say "Equal Opportunity Employment" or "Affirmative Action" a lot and you'd probably hear Republicans say "Laissez-faire" or "Free Market" a lot. What would be the antithesis of these phrases for the other side? I would posit that it's entirely possible that these articles are not on average biased and instead are merely explaining and using the phrases that each party has employed to tackle their number one priorities.

On top of that, I didn't see anything that seemed to indicate that they used windowing to determine when a phrase was opposed to the phrase they were using. For example if you found that the acronym ACORN indicates a Democratic slant but there's a whole section on its Wikipedia page full of negative criticism despite them using 'ACORN' frequently in that section. Would this section be identified as a Democratic slant?

Where is this G&S word bank? Where is the list of results so I can look up the ACORN article's scores?

Re:How to write without political bias?

[vlm]

What can be done to avoid political bias and how do we do it consistently?

Don't write about political topics that are relevant to you?

For example writing about modern civil rights (gay marriage, gun rights, etc) in the USA is going to get a intention and/or unintentional bias from me.

However if I research and report on the political situation in France, where I have no dog in the fight, I'll probably end up pretty much unbiased.

Its a big interconnected world... there's really no reason for locals to have to write biased filler about local issues.

Doesn't have to be geographic. I have no personal interest in the gay marriage thing, not being gay or close to those in their subculture and not being hyper-christian, so I can be extremely unbiased about the topic. This SHOULD work, but it fails anyway, because my completely unbiased view unsurprisingly seems to match the (few) non-cowardly (D) and oppose almost all the neo-(R) so I'll be accused of being "politically biased" based on results, although I obviously don't have any reason to care that would influence the process of writing about it. Think of how everyone naturally decides that slavery was a dumb idea now, but it was a hot political football around 1860 or so in the USA.

There's some other hints, like if you find evidence of sloganeering in your writing you're probably doing it wrong.

'America' appears 7 times in the article 'Irish republicanism' (3 times as 'America' 4 in 'American') and so by their metric (must occur 3 or more times) it would go in, in spite of being nothing at all to do with the US political party of the same name.

And this article is example 1: Apodixis

[Anonymous Coward]

Bias is rhetoric. Apodixis: A rhetorical device that stealthily inserts a false pretense of general knowledge. For example "As everyone knows..."

Or, as this article does: "expected political slant - civil rights tends Democrat"

Republicans broke the Democrats filibuster of the Civil Rights Laws of the 60's. The Republican Party was formed for the sole purpose of overturning Democratic Legislation that allowed slavery to expand into the Western Territories. The first Republican President freed the slaves. Every Governor of every state that let loose the fire hoses on and dogs on minority students was a Democrat.

Study rhetoric, and don't fall for it. We are most vulnerable to the rhetoric we cheer for. That's where we should put most of our scrutiny.
Being tricked by adversary is bad enough, being tricked by someone you support is truly insulting.

There are no other points of view.
