Platt's Principle is a concept in psychology that suggests that the accuracy of a person's predictions about future events is influenced by their past experiences. Essentially, it posits that individuals tend to rely on their previous knowledge and experiences to make judgments about what is likely to happen next. This principle highlights the importance of learning from past outcomes to improve decision-making. The principle is often applied in various fields, including economics, sports, and forecasting. By understanding how past events shape expectations, individuals and organizations can better prepare for future scenarios, ultimately enhancing their ability to make informed choices.
