Doubt is a feeling of uncertainty or skepticism towards a belief, decision, or outcome. It arises when one questions the validity, truthfulness, or reliability of something. Doubt encourages critical thinking and can be beneficial in challenging assumptions and finding truth. It can stem from various sources such as lack of evidence, contradictory information, or personal insecurity. Doubt often leads to seeking clarification or evidence to confirm or refute ideas. While doubt can hinder progress and confidence, it can also serve as a motivator for deeper understanding and growth. How doubt is managed and resolved greatly impacts decision-making and personal development.
