During the winter of 2000, truckers blocked the main roads in and out of the Norwegian capital Oslo. The main cause was low profitability in the business, and the reason for that was claimed to be a steady increase in the environmental tax on diesel oil the preceding five years. As a consequence, the politicians removed the tax. When doing so, some politicians neglected the philosophical ground of being for their parties, and a majority of them ignored Kyoto Treaty obligations and stated preferences for green taxes. In this paper, I claim that all this happened because: Voters, media and policy makers do not quantify their arguments. Their focus is on actions rather than causes. Adam Smith’s invisible hand is still ’invisible’. There seems to be no institution readily available to correct misperceptions.
