One survey question, asked of about a thousand people in more than 140 countries each year, decides which nation is called happiest. The episode traces the Cantril Ladder to Hadley Cantril, the Princeton psychologist behind the War of the Worlds panic study and wartime opinion research, through Gallup's World Poll, Bhutan's UN resolution, and the first World Happiness Report in 2012.
Scholars argue the 1938 mass panic was largely a newspaper-made myth. The ladder may prime thoughts of money and status, and cultural response styles may shift scores. Single-place rank differences often fall within overlapping confidence intervals.
