‘Truthiness’ and Expression

There was an interesting article on Huffington Post by Chris Mooney, author of The Republican Brain, about the word ‘truthiness’ which was first used by Stephen Colbert on his The Word segment to describe the ‘quality of knowing something in your gut or your heart, as opposed to in your head’. It turns out that this relative bias does actually have some scientific basis in psychology and neuroscience as Mooney describes it in the article. He goes on to discuss the possible differences between conservative vs liberal brains.

Interesting, but what really caught me from a linguistic point of view what Colbert’s use of Expression stratum to emphasize this difference. Here is his definition of Truthiness:

Truthiness is, ‘What I say is right, and [nothing] anyone else says could possibly be true.’ It’s not only that I feel it to be true, but that I feel it to be true. There’s not only an emotional quality, but there’s a selfish quality.

Note the difference in meaning between “I feel it”, where the mental Process is emphasized (the “emotional quality”), and “I feel it”, which highlights the self as Participant (“selfish”). The key for Colbert’s definition, therefore, hinges not on a lexico-grammatical distinction but on a phonological one. I imagine this difference would be difficult for most learners if they only consider Expression in terms of ‘sounding natural’ and not how it relates to the Content stratum.
