|---|---|
| Cantril Ladder | The Cantril Ladder is a visual scale used to assess general life satisfaction. It asks respondents to evaluate their lives on a ladder from worst (bottom) to best (top) possible life, making it a simple tool to measure subjective well-being. This measure has been widely used in various studies and surveys, including the Gallup World Poll, which collects data from over 140 countries annually. |
