انتظار (Expectation) refers to the anticipation or belief that something will happen in the future. It can be based on past experiences, social norms, or personal desires. Expectations can influence behavior and decision-making, as individuals often act in ways that align with what they believe will occur. In psychology, expectations play a significant role in shaping perceptions and outcomes. For instance, the placebo effect demonstrates how a person's belief in a treatment can lead to real changes in health. Similarly, cognitive biases can affect how people interpret information based on their expectations, impacting their judgments and actions.
