A conspiracy is a secret plan made by a group of people to achieve a specific goal, often involving illegal or harmful actions. These plans are usually hidden from the public and can involve various individuals or organizations working together. Conspiracies can range from small-scale schemes to large, complex plots that may affect many people. Conspiracy theories arise when people believe that certain events or situations are the result of these secret plans, even without solid evidence. Examples include theories about government cover-ups or corporate manipulation. While some conspiracies have been proven true, many remain unverified and can lead to misinformation.
