Research was conducted, looking at three countries - Lebanon, Poland and the US, and comparisons were made between presidential speeches made by representatives of conservative and liberal political parties.
In the study, which can be found in the Political Psychology journal, Dr Aleksandra Cichoca asserted that:
In two studies we obtained consistent support for the hypothesis that conservative political orientation is associated with a linguistic preference for nouns.
Another interesting prospect is that political inclinations are affected by subtle linguistic cues, so that exposure to more abstract language could shift the receiver's political orientation in a conservative direction, at least under some circumstances. To the extent that conservative politicians use more nouns than liberal politicians in political speeches, this may serve a strategic function.
Noun forms may also turn out to be more persuasive to conservatives than liberals.
Nouns, it seems, are a conservative's best friend.
