I have a feeling if OP had read some of the papers surrounding Daniel Kahneman (and the works Kahneman cited) he wouldn't be so sure about mankind's rationality.

It's like the vast majority of experiments on the subject ends up with "and then they proceeded to use their intuition and who they like more to make their decision".

Also, I think it was "Classical Rhetoric for the Modern Student" that also said that logical arguments are the weakest kind of rhetorical arguments since basically anything else is more likely to convince people.
