Fortune-telling is a traditional method of divination that uses various symbols, numbers, or other means to speculate on a person's future or character. There are many ways of fortune-telling in different cultures, such as the eight characters, tarot cards, and horoscopes. Although many people believe that fortune-telling can provide guidance and enlightenment, from a scientific point of view, there is no reliable basis for fortune-telling to accurately predict future events. Many psychological studies have shown that the accuracy of fortune-telling often relies on the "ambiguity effect" (Barnum effect), that is, people tend to match broad, vague descriptions with their own personal circumstances, resulting in a sense of "accuracy". In general, fortune-telling may provide some interesting insights or a tool for personal reflection, but it is not a scientific method and cannot be regarded as an accurate prediction of the future. When people face the future, it is more important to rely on personal choices and actions.
