The term 'Show Me State' is a nickname for the U.S. state of Missouri, which has 8 letters. SKEPTICISM is a 10-letter word meaning a questioning attitude or doubt about accepted opinions. The phrase 'Show Me State' is derived from a saying attributed to Missouri's U.S. Congressman Willard Duncan Vandiver in 1899, who said, 'I'm from Missouri and you've got to show me.' This phrase has come to represent Missouri's independent spirit and its citizens' insistence on proof before accepting something as true.
