A political spectrum is a system of classifying different political positions upon one or more geometric axes that symbolize independent political dimensions. - Political Spectrum - Wikipedia
The Nolan Chart is a political spectrum diagram. The chart divides human political views into two vectors—economic opinion and personal opinion—to produce a type of Cartesian chart. It expands political view analysis beyond the traditional "left–right" line, which measures politics along a one-dimensional line, into a graph with two dimensions: degrees of economic freedom and personal freedom. - Nolan Chart - Wikipedia
The Political compass (much more popular) is the Nolan chart rotated 45° clockwise and flipped vertically.
Is it true that radicals and reactionaries, falling on the edges of the compass, are the most deontological? And that centrists are the rational consequentialists? Is there a correlation? Or is it more complex and thus a 3rd axis would be informative?
