Luce's Choice Axiom

Luce's Choice Axiom states that the probability of choosing one option over another depends only on the relative attractiveness or preference of those options, and this ratio remains consistent regardless of other available choices. In simple terms, if you prefer option A over B, adding or removing other options won't change that ratio of preference between A and B. This principle helps model decision-making behaviors consistently, ensuring that preferences are transitive and proportionate, and it forms the foundation for how choices are predicted in probabilistic models of choice behavior.
