A think tank is an organization that conducts research and provides advice on various issues, often related to public policy, economics, or social matters. These groups typically consist of experts, scholars, and analysts who study complex problems and propose solutions. Think tanks can be independent or affiliated with universities, governments, or political parties. Think tanks play a crucial role in shaping public discourse and influencing decision-makers. They publish reports, host events, and engage in discussions to disseminate their findings. Notable examples of think tanks include the Brookings Institution, Carnegie Endowment for International Peace, and the Heritage Foundation.
