For example, the intensity of preference is a one of many factors which are important in voting. The term is a measure of an individual voter's (or group of voters') willingness to do something. Intensity of preference focuses on the inconveniences involved in the act of officially registering a choice at a specific time and place, not the vote itself. For example, the lines for voting in South Africa's 1994 election were very long. The "intensity of preference" and the inconvenience of voting were factors in the election of Nelson Mandela.
