“Man on the street“

Americans believe that complexity is only truly understood when it can be explained to the man on the street, meaning to the non-expert. To persuade in the American context means to use clear, transparent, straightforward language, spoken and understood by those of average education.

This is not a form of dumbing-down, but effective communication. Put differently, Americans believe that if you cannot make the complex understandable, then you have not mastered that complexity.
