A large fraction of my traffic these days comes from school sites. Sex, drugs, and rock ‘n roll are a lot more appealing if you are a teenager than if you are a parent of a teenager. I think this explains most of the bias to the upper left.
Then again, it is also possible that the government is biased to the lower right compared to the population. I center the diagram on the amount of government we have today vs. any attempt at finding an average or median viewpoint. Whereas a democracy is supposed to reflect the median in theory, in practice we have Gerrymandering, a two-party system, and a funding bias towards towards incumbents — i.e., bribery.
There are more people at the upper corner than at any of the other corners because the Nolan Chart is a projection of a higher dimensional space that makes libertarianism appear a more coherent political philosophy than others. Other projections are possible. The Political Compass uses a different projection which measures how libertarian you are not at all, but does measure how much you agree with a certain hard left political philosophy.
