When classifying European parties, I feel it is the height of stupidity to conflate economic and social left/right. Not only is there no correlation, but in some regions and ideologies, there is anti-correlation -- meaning that parties are at opposite extremes in the economic and social dimensions, resulting in a fake 'moderate' position in the conflated economic-social dimension.

Then again, a 3D map would be more difficult...
