To "scrutinize" means to examine something very carefully and in detail. This process often involves looking for specific information, flaws, or important features. People might scrutinize documents, artwork, or even a person's behavior to gain a deeper understanding or to make informed decisions. In various fields, such as science or law, scrutiny is essential for accuracy and reliability. For instance, researchers scrutinize data to ensure their findings are valid, while lawyers scrutinize evidence to build a strong case. This careful examination helps prevent mistakes and promotes thorough analysis.
