A think tank is a group or an organization that engages in research and analysis to develop new ideas, policies, and solutions for various social, political, economic, and cultural issues. These organizations typically consist of experts from different fields who come together to share their knowledge, expertise, and perspectives on important topics. Think tanks often provide policy recommendations to governments, businesses, and other institutions, and they may also publish reports, articles, or books to disseminate their ideas to a wider audience. The term "think tank" is used to describe both independent organizations as well as those that are affiliated with universities, research institutes, or political parties.
