Presidential speech word patterns

In the continuing saga of presidential campaign speech language, I’ve been analyzing parts of speech that don’t get much attention such as verbs, adverbs, and adjectives. Looking at the way in which each candidate uses such words over time turns up some interesting patterns. I don’t understand their deep significance, but there’s some work suggesting that variability in writing is a sign of health; and Ashby’s Law of requisite variety can be interpreted to mean that the actor in a system with the most available options tends to control the system.

Here are the plots of adjective use (in a common framework) for the 2008 and 2012 candidates (up to the time that Santorum dropped out of the race).

It’s striking how much the patterns over time form a kind of spiral, moving from one particular combination of adjectives to another and another and eventually back to the original pattern. The exception is Obama who displays a much more radial structure, with an adjective combination that he uses a lot, and occasional deviations to something else, but a rapid return to his “home ground”.

You can see (the extremal set of) adjectives and their relationships in this figure:

You can see that they form 3 poles: on the left, adjectives associated with energy policy; at the bottom, adjectives associated with patriotism; and on the right, adjectives associated with defence [yes, it is spelled that way]. This figure can be overlaid on those of the candidates to get a sense of which poles they are visiting. For example, Obama’s “home ground” is largely associated with the energy-related adjectives.

Comparing content in the US presidential campaign 2008 vs 2012

I posted about the content in the 2012 presidential campaign speeches. It’s still relatively early in the campaign so comparisons aren’t necessarily going to reveal a lot, but I went back and looked at the speeches in 2008 by Hillary Clinton, McCain, and Obama; and compared them to the four remaining Republican contenders and President Obama so far this year.

Here’s the result of looking just at the nouns:

The key is:   Clinton — magenta circles; Obama 2008 — red circles, McCain — light blue stars;

Gingrich — green circles; Paul — yellow circles; Romney — blue circles; Santorum — black circles; Obama 2012 — red squares.

Recall that the way to interpret these plots is that points far from the origin are more interesting speeches (in the sense that they use more variable word patterns) while different directions represent different “themes” in the words used.

The most obvious difference is that the topics talked about were much more wide-ranging in 2008 than they have been this year. This may be partly because of the early stage of the campaign, the long Republican primary season keeping those candidates focused on a narrow range of topics aimed at the base, or a change in the world that has focused our collective attention on different, and fewer, topics.

This can be teased out a bit by looking at the words that are associated with each direction and distance. The next figure shows the nouns that were actually used (only those that are substantially above the median level of interestingness are labelled):

You can see that there are four “poles” or topics that differentiate the speech content. To the right are words associated with the economy, but from a consumer perspective. At the bottom are words associated with energy. To the left are actually two groups of words, although they interleave a little. At the lower end are words associated with terrorism and the associated wars and threats. At the upper end are words associated with the human side of war and patriotism.

These two figures can be lined up with each other to get a sense of which candidates are talking about which topics. The 2012 speeches and Obama’s 2008 speeches all lean heavily towards the economic words. In 2008, McCain and Clinton largely talked about the war/security issues, with a slight bias by Clinton towards the patriotism cluster.

Obama’s 2012 speeches tend towards the energy cluster but, at this point, quite weakly given the overall constellation of topics and candidates.

The other thing that is noticeable is how similar the topics for some of the Republican contenders are: their speeches cluster quite tightly.

2012 US Election, Republicans plus President Obama

Yesterday I posted details about the levels of persona deception in the speeches by the Republican candidates since the beginning of 2012. In striking contrast to the 2008 cycle, the speeches fall along a single axis, indicating widespread commonalities in the way that they use words, particularly the words of the deception model.

Today I’ve included President Obama’s speeches this year in the mix. I’ve tried to select only those speeches where there was an audience. Of course, for a sitting president, the distinction between an ordinary speech and a campaign speech is difficult to draw. Almost all of these are labelled as campaign events at whitehouse.gov.

Here is the plots of the persona deception levels, with Obama’s speeches added in magenta.

Generally speaking, Obama’s levels of persona deception (see yesterday’s post to be clear on what this means) are in the low range compared to the Republican presidential candidates. This is quite different from what happened in the 2008 cycle, where his levels were almost always well above those of McCain and Clinton. It’s not altogether surprising, though. First, he can no longer be the mirror in which voters see what they want to see since he has a substantial and visible track record. Second, he doesn’t have to try as hard to project a persona (at least at this stage of the campaign) since he has no competitor. I expect that his values will climb as the campaign progresses, particularly after the Republican nominee becomes an actual person and not a potential one.

The interesting point is the outlier at the top left of the figure. This is Obama’s speech to AIPAC. Clearly this is not really a campaign speech, so the language might be expected to be different. On the other hand, if it were projected onto the single-factor line formed by the other speeches, it would be much more towards the deceptive end of that axis. Since the underlying model detects all kinds of deception, not just that associated with persona deception in campaigns, this may be revealing of the attitude of the administration to the content expressed in this speech.

Language in Presidential Elections — 2012 Season Opener

Readers of this blog will know that we spent a lot of time analyzing the speeches of the U.S. presidential candidates in the 2008 election. Our primary interest was in the use of the deception model, a linguistic/textual model of how freeform language changes when the speaker/writer is being deceptive.

In the political arena, factual deception, saying things that just ain’t so, plays very little role, perhaps because voters have very low expectations of politicians in this area. What we call persona deception, presenting oneself as a better,wiser,  more powerful, more able, more knowledgeable person than one really is is the heart of successful campaigning. It turns out that the deception model captures deception across the whole range from factual to persona deception, so it gives us a lens to look at candidates and campaigns. What’s more, because language generation is almost entirely subconscious, this lens is hard to fool.

The most important skill candidates and their campaigns have is the ability to reach out to potential voters to convince them that they are better than the other possibilities. The language that they use is an important channel, especially in settings where everyone is conservatively dressed, and standing behind a podium that conceals most of their body language, as the Republican presidential field was in Iowa yesterday.

Strong candidates understand, at least instinctively, that they are not making arguments to convince voters, but presenting themselves as more compelling human beings. Our analysis of the speeches of candidates in the 2008 U.S. presidential election showed that candidates use three different kinds of speeches: blue skies speeches that promise generically good things and could be delivered interchangeably by any candidate – they are aimed at a wide audience; track record speeches that use past achievements to imply special qualifications for future achievements – they are aimed at swing voters; and manifesto speeches that describe a candidate’s personal qualities directly – they are aimed at a candidate’s base and reinforce common identity. But in all three cases, it’s not the content of the speech that matters, but what it implies about the speaker.

Our analysis in the last election cycle showed that Obama was by far the best as presenting himself as a wonderful person, and many voters, and certainly many in the media, projected onto the persona  positive qualities that were perhaps not there. Interestingly, yesterday was the first time I have seen open Democratic buyers remorse about electing Obama, something I predicted would happen from the analysis we did.

The Republican candidates’ debate in Ames showed what a shaky grasp many of the candidates have on how to be a convincing candidate. Of course, this venue was a difficult one. Its overt purpose was for candidates to explain themselves to the local Republican base ahead of the Ames Straw Poll,which would have required largely manifesto content; but national television coverage made it an unmissable opportunity to reach out to a wider, but much more diverse audience, suggesting track record content. Blue skies content is always dangerous in the early stages of a campaign because grand but potentially unwise statements can come back to haunt a candidate.

Manifesto content was indeed popular – for example, we learned how many children almost every candidate has – typical content aimed at the base (“I’m a parent just like you”). Several candidates also tried for track record content, but got it quite wrong. The purpose of a track record speech is not for candidates to read their resumes to the audience; it’s to make the argument “I was able to do A, so you can trust me to be able to do similar-but-larger B” and this second part was notably absent.

Voters also want candidates to be sincere — recall the famous quotation “The secret of success is sincerity. Once you can fake that you’ve got it made” (Jean Girardoux). This is not just a cute quotation; this is what good politicians are able to do. In Iowa, this was another area where almost everyone stumbled. It was clear that most of the candidates had not only prepared talking point responses to probable questions, but has also rehearsed actual answers. Delivering from a prepared and memorized script and seeming sincere is a difficult business, and actors who can do it reliably command high rewards.  Most of the candidates failed at seeming sincere. Several managed the worst of both worlds by trying to combine their prepared scripts with some ad libbing and came across as quite incoherent. One of the reasons for Gingrich’s strong showing is that he stayed away from scripts and delivered his answers as if he had just thought of them. Huntsman and Romney, in contrast, were especially wooden.

When humans listen to humans, the content matters. But when character is the issue, other aspects of language matter more. Much language generation is subconscious, and therefore beyond a candidate’s control. This is good for voters because it means we can sometimes see through to the real person no matter how sophisticated their speech writers and spin doctors.

Language Patterns in the UK Election

There’s a nice article in New Scientist about the work of Pennebaker’s group, looking at the language patterns in the leaders’ debate last week in the UK election campaign. Details here.

Content in election speeches

I went back and looked at the collection of speeches by the three contenders in the 2008 U.S.presidential election, not from the point of view of spin, but just looking at what they were about. The results were a little surprising. Despite all of the thinking and polling that goes into a campaign, the speeches were about only three topics.

Structure of word usage in speeches

These three topics are: the economy, associated with words such as crisis, jobs, plan, pay; security, associated with words such as war, threat, Iraq, allies; and family, associated with words such as parents, children, living. This last group features only early in the campaign and a single speech by Obama given on Fathers Day.

It’s no surprise that these topics appear. What does seem surprising is how little else was mentioned: other topics words are all hidden in the center of the figure indicating that their pattern of appearance in not very interesting.

Canadian Federal Election — first analysis

I’ve done some analysis of the party leader speeches from the first week of campaigning. I am somewhat hampered by lack of data; only one speech by Jack Layton has been posted, and there are only three by Dion.

About the only conclusion so far is that language patterns are all over the place. There is no consistency in any of the campaigns. This might be because speechwriters are still settling in (but surely Harper’s at least must have known the election was coming?). Or it may be that all of the campaigns are unsure of their strategies in some less-conscious way. But it’s interesting, and slightly puzzling.

I’ll await more data.

Improving the process of detecting deception

The main problem with Pennebaker’s deception model, discussed in an earlier post, is that the signal for deception for two of the word classes is a decrease in word frequencies. But a decrease with respect to what? Without some care, a text that does not use any of certain word classes can look unusually deceptive, just because it happens not to use certain kinds of words. For example, formal business writing almost never uses first-person singular pronouns (“I”, “me”, “my”) so an occasional text that used one or two might be considered undeceptive just on that basis.

It’s better to consider the deceptiveness of a group of documents or texts from a common domain, and rank them from most to least deceptive, rather than imagining that deception is a kind of absolute property. Then it’s clear that decrease means “frequencies that are lower compared to the norms of documents in this domain”.

It also turns out to be useful to consider the correlations between word usage across the documents in a domain. There may be conventions about the way in which ideas are expressed that go beyond simple word frequencies. So deception detection is improved by considering the correlation among messages, and using it to pick out documents that are more unusual for enhanced consideration. This is the approach I’ve used to look at Enron emails and politicians’ speeches, for example
here for the US presidential election in February 2008, and
for the Canadian Federal election in 2006.
