In an analysis of voting, for example, the intensity of preference is a measure of an individual voter's (or group of voters') willingness to incur the costs or inconvenience of the act of officially registering a preferential choice at the time and place required, not the vote itself.
[Arrow, Kenneth J. (1963). ]
Social choices
The "intensity" of preference can be a factor in aggregating individual choices into social choices.

"Proof of Arrow's Impossibility Theorem,"
citing J. Kelly, ''Social Choice Theory: An Introduction''
:Independence of irrelevant alternatives "... does not rule out "intensity" of preference in making social choices.
:(1) "It is part of our definition of a social choice rule/function that the choices are based only on the information in a profile of ordinal preference relations.
:(2) "These preference relations do not contain any intensity information that could be used by social choice rules, whether or not they violate the independence axiom."
