Uncertainty, or doubt, refers to a state of having questions or lacking confidence about something. It can arise in various situations, such as making decisions, evaluating information, or predicting outcomes. This feeling can lead to hesitation and may affect how individuals approach challenges or opportunities. In psychology, uncertainty is often linked to anxiety and stress, as individuals may worry about the unknown. It can also play a role in critical thinking, prompting people to seek more information or consider different perspectives before reaching a conclusion. Understanding and managing uncertainty is essential for effective decision-making.
