Now very quickly this runs into complications as their are actually two common axes that are not that closely correlated. They are the economic and social axes. The economic axis has capitalism at one end (i.e. no restrictions on money and business) and socialism at the other (i.e. government command of all important parts of the economy). Meanwhile the social axis has anarchism at one end (i.e. minimal restriction of self expression) and authoritarianism at the other (i.e. strength through conformity). This has long since been developed into the political compass model (my own version show below):
But a few years ago I wondered, could you fit a third axis on here, making the Political Compass three-dimensional, and if so what would that axis represent. After some musing I came up with the foreign affairs scale with globalism (i.e. attempt to influence or cooperate with other countries) versus isolationism (i.e. focus exclusively on the home country).
An important factor in trying to make a three-axis political spectrum graph is that the axes are not equally important. As a crude measure I would rate the economic scale out of nine, the social scale out of seven and the foreign scale out of five in terms of importance to individuals. Thus you get something like this:
The labels I went with have been chosen with to cause least confusion, but I could have replaced conservatism with authoritarianism and liberalism with anarchism for instance. Edit: I did.
The corners have been cut off the 2D graph because I don't believe there is much in the way of a difference in practice between communism (top left) and fascism (top right) or between anarcho-syndicalism (bottom left) and anarcho-capitalism (bottom right).
I think the ideal graph should result in the vast majority of people ending up in the middle.
The graphs have been changed with new labels added following commenter feedback. + Show Spoiler [old graphs] +
