New Scientist (a magazine that is incredibly interesting, but it is such an incredibly liberal mag, that I decided not to renew my subscription) has a very interesting article out about scientists that study micro-expressions and spin in political speeches:
BLINK and you would have missed it. The expression of disgust on former US president Bill Clinton’s face during his speech to the Democratic National Convention as he says “Obama” lasts for just a fraction of a second. But to Paul Ekman it was glaringly obvious.

Technology is here to help. Software programs that analyse a person’s speech, voice or facial expressions are building upon the work of researchers like Ekman to help us discover when the truth is being stretched, and even by how much. “The important thing to recognise is that politicians aren’t typically good at out-and-out lies, but they are very adept at dancing around the truth,” says David Skillicorn, a mathematics and computer science researcher at Queen’s University in Kingston, Ontario, Canada. “The 2008 election has so far given us plenty of chances to see them in action.”
Skillicorn has been watching out for verbal “spin”. He has developed an algorithm that evaluates word usage within the text of a conversation or speech to determine when a person “presents themselves or their content in a way that does not necessarily reflect what they know to be true”.
[...]
Each of the candidates had made speeches containing very high and very low levels of spin, according to Skillicorn’s program, depending on the occasion. In general though, Obama’s speeches contain considerably higher spin than either McCain or Clinton. For example, for their speeches accepting their party’s nomination for president, Obama’s speech scored a spin value of 6.7 – where 0 is the average level of spin within all the political speeches analysed, and positive values represent higher spin. In contrast, McCain’s speech scored -7.58, while Hillary Clinton’s speech at the Democratic National Convention scored 0.15. Skillicorn also found that Sarah Palin’s speeches contain slightly more spin than average.
So the analysis appears to back up McCain’s claim that he is a “straight talker”. However, for the purposes of political speech-making this may not be an entirely good thing for him. “Obama uses spin in his speeches very well,” says Skillicorn. For example, Obama’s spin level skyrockets when facing problems in the press, such as when Jeremiah Wright, the reverend of his former church, made controversial comments to the press.
“When you see these crises come along, the spin goes up,” Skillicorn says. “Obama is very good at using stirring rhetoric to deal with the issues. And it seems to work if you look at what happens in the polls afterwards.”
Ouch!
