1) The document examines whether using "penny" instead of "percentage" to describe economic policies in the UK distorts perceptions of their significance. It traces the historical origins of this practice back to the Napoleonic Wars, when penny was used because percentages were less familiar. 2) While penny avoids some ambiguity associated with percentages, its continued use distorts the interpretation of policies through its effect on language. Penny has little practical meaning today given inflation. 3) The document recommends replacing penny with percentage to minimize distortions and clarify policies' meanings. It suggests pursuing both a petition campaign and discussions with MPs to build support for the change.
