“We have the Mississippi Valley Association of State Highway Departments to thank for the stop sign’s iconic shape. In 1923, the association developed an influential set of recommendations about street-sign shapes whose impact is still felt today. The recommendations were based on a simple, albeit not exactly intuitive, idea: the more sides a sign has, the higher the danger level it invokes. By the engineers’ reckoning, the circle, which has an infinite number of sides, screamed danger and was recommended for railroad crossings. The octagon, with its eight sides, was used to denote the second-highest level. The diamond shape was for warning signs.”
“the circle, which has an infinite number of sides, screamed danger…”
circles always scream danger to me. you?
message and intent feel appropriate, even inspired, when you’re in the huddle working on the problem. take two steps outside the group, however, and suddenly both may be missing.
