Preference Theory is a concept in economics and decision-making that suggests individuals make choices based on their preferences and the perceived utility of different options. It posits that people evaluate alternatives and select the one that maximizes their satisfaction or benefit, taking into account their personal tastes and circumstances. This theory is often applied in various fields, including behavioral economics and consumer behavior, to understand how choices are made. It emphasizes that preferences can be influenced by factors such as cultural background, social influences, and individual experiences, leading to diverse decision-making processes among different people.
