The New Orleans Times-Picayune
(or what’s left of it) picked
up on a piece, mentioned in several, mostly trendy lefty, media sites,
about an investigation of Twitter microblog communications (“tweets”) by a
group of geographers in the runup to election day last week that contained what
they coded as “racist” in nature. It proclaimed that Louisiana was the
fifth-highest location of such tweets, at 3.3 times the norm.
The idea found its inspiration from the website Jezebel, not exactly
celebrated for the analytical quality nor the intellectual heft of its post-feminist
contents and writing (as of this writing, its lead article weighed the question
no doubt every intelligent woman of high self-esteem routinely ponders, “Some
Things to Consider When You Think You Want to be a Prostitute”), where somebody
bored enough decided to collect some post-election tweets with decidedly
anti-black language. The geographer crowd at a group called Floatingsheep picked
up on it, produced
results and extended
commentary, pronouncing conclusions echoing a mildly ersatz version of the identity politics/post-Marxism all too prevalent
coming from academia: “Racist behavior, particularly directed at African
Americans in the U.S., is all too easy to find both offline and in information
space.”
And, “we believe that the concentration of racist tweets in the South
is indicative of the persistence of racism in the South, which is correlated
with, though not necessarily causally-related to, statewide voting for Mitt
Romney.” And, finally, “we hoped to use this exercise to show the persistence
of racism.” But their problem is, their analysis does nothing of the sort.
Understanding that what they did was not designed as a major research
effort but more on the fly, so you can be a bit picky about it. Their coding
scheme (what words were used as triggers to identify a message coded as racist)
was somewhat incomplete and subjective (they questionably imputed non-racist
content to at least one slang term generally considered racist). Theirs may not
be a representative sample because the protocol they used to be able to
identify the state from where a tweet came (“geotagging”) may not be randomly
distributed among cell phone users, nor did they control for the number of
messages sent out by users (for example, very plausibly a true racist would
have been more excitable and exercised by the election and tweeted out of
proportion to other users, where they assumed each tweet represented a unique
individual). Any or all of these cast questions of validity over their
conclusions.
However, setting these aside, they commit a fundamental error in statistical
inference – it’s not the quality of the data that may mislead them, but in
their understanding about what it means. As a teacher of research methods, I
have found decade in and decade out the most difficult task of students is to
interpret tests of data into a substantive meaning. And while I do not know
whether graduate level geography study requires coursework in research methods,
if this group had them, then the mistake they made in logical inference does
them no credit.
Even if we did a test of means that showed a significant difference,
for example, between Louisiana and the nation in the number of “racist” tweets,
consider that they identified 395 tweets coded as “racist” that represented
about 0.05 percent of the total reviewed – in other words, they collected a
sample of size roughly 790,000 and found
only 395 “racist” tweets among them. In other words, about 1 in every 2,000
tweets sent had “racist” content nationally, and in Louisiana the level was around
1 in 600. And they want us to buy the argument that there is “persistence of
racism” when 1 out of 600 people make such remarks? You’d have a stronger
chance of arguing racism was on its deathbed with a statistic like that, if
that’s all the people out there willing to voice racist sentiments (assuming
the distribution of “racism” was the same between the tweeting and non-tweeting
public).
The untutored student, if I set out for them a question with a null
hypothesis that racism doesn’t exist (that is, the population mean of remarks
is 0) with a sample that found some, and then did means tests comparing
regions, with a sample size of n=790,000 for the first and among all for the
second, I’ll bet analyses mathematically would find statistically significant
relationships that might tempt the conclusions that racism is alive and well and
it’s more common in the South, leading one to say it could be related to a vote
for a white presidential candidate facing a black one. But it has no
substantive meaning because the levels are so low. It’s like taking 600 ml of olive
oil, adding a single cc of vinegar, and declaring it salad dressing.
It’s not, it’s just very slightly diluted oil. But that’s the rationale
behind this declaration of significant racism in America. A miniscule number of
tweets relative to a far larger whole simply does not sustain that
interpretation; all it tells us is that a few nimrods are out there but in no
way represent any constituency of even the tiniest significance in American
politics and society. The untutored student might be pleased to have found a
significant relationship that the two means differ in the first instance and
that in the second case the mean varies significantly by region and even
strongly, but these results together do not then warrant a declaration that the
sample is evidence that the population exhibits characteristics in a way that demonstrates
“persistence of racism.”
However, that does not fit the narrative pushed in academia that a
significant portion of American political behavior, particularly among white
Southerners, can be explained by “racism” (whether genuine or manufactured by
researchers relying on an invalid concept called “symbolic racism,” that, for
examples, says it’s “racist” not to think that racism explains why generally
blacks are poorer than whites). The 1991 governor’s contest in Louisiana
provided potential fodder for this view, since
refuted, and, despite revisionist efforts since, imputed racist motives
never have been demonstrated to impact Louisiana voting outcomes in the
post-civil rights era, because the proportion of the public that uses racist
attitudes in a meaningful way in their voting choice remains so small. Yet the mythology
from the academy continues.
