Spin scores to the end of October

Here is the analysis of levels of spin in Obama and McCain’s speeches up to a few days ago. Usual labelling (refer to previous posts for background).

Spin scores (red - McCain, blue - Obama)

Spin scores (red - McCain, blue - Obama)

The most obvious thing to see in this plot is how McCain’s speeches all tend to lie on one side of the deceptiveness axis while Obama’s tend to lie on the other side. This is because McCain has started using motion words at high rates (and Obama does not). This has a small effect on deceptiveness score, but rates of use of motion verbs are not all that important to signalling deception.

The individual levels of spin from the convention to the end of October are here:

McCain

Obama

Obama

The last time I posted was during the period where Obama’s level of spin was quite low. As you can see, it has risen sharply again in the past week. This suggests that he is not as confident of winning now as he was then — he has consistently shown a pattern of stepping out from his facade and using lower spin when he feels confident about winning.
