Fair enough. Writing is actually kind of hard, and we should have some leeway in word choice and in forming our narratives without being constantly accused of egoism.
My wife is a designer, and her job involves lots of rigor even if her role is classified as creative (10% creativity, 90% perspiration!). I'm willing to give a pass to anyone who says a professional design involved "deep intellectual rigor" even if the design has yet to be evaluated by the marketplace.
