A preference is a technical term in psychology, economics and philosophy usually used in relation to choosing between alternatives: someone has a preference for A over B if they would choose A rather than B.
In psychology, preferences could be conceived of as an individual’s attitude towards a set of objects, typically reflected in an explicit decision-making process (Lichtenstein & Slovic, 2006). Alternatively, one could interpret the term “preference” to mean evaluative judgment in the sense of liking or disliking an object (e.g., Scherer, 2005) which is the most typical definition employed in psychology. However, it does not mean that a preference is necessarily stable over time. Preference can be notably modified by decision-making processes, such as choices (Brehm, 1956; Sharot, De Martino, & Dolan, 2009), even unconsciously (see Coppin, Delplanque, Cayeux, Porcherot, & Sander, 2010).
In economics and other social sciences, preference refers to the set of assumptions related to ordering some alternatives, based on the degree of happiness, satisfaction, gratification, enjoyment, or utility they provide, a process which results in an optimal "choice" (whether real or imagined). Although economists are usually not interested in choices or preferences in themselves, they are interested in the theory of choice because it serves as a background for empirical demand analysis.
"Preference" may also refer to non-choices, such as genetic and biological explanations for one's preference. Sexual orientation, for example, is no longer considered a sexual preference by most individuals, but is debatable based on philosophical and/or scientific ideas.
