What Is the Nolan Chart Based On?

The Nolan chart is based on the analysis of a particular person's political viewpoint. It is a visual representation of the political spectrum, measuring liberal versus conservative tendencies as well as libertarian and statist tendencies.

The Nolan chart was created by David Nolan — a Libertarian political scientist and lead founder of the Libertarian Party. Nolan oriented personal freedom issues along the Y axis and economic issues along the X axis, creating a two-dimensional chart analyzing a person's political viewpoint. The chart was modified by Marshall Fritz who added a 10-question quiz and turned it 45 degrees counter-clockwise, changing the chart into a diamond shape.
