Think tanks are organizations that conduct research and analysis to influence public policy and decision-making. They often focus on specific areas such as economics, education, health, or international relations. By providing expert insights and recommendations, think tanks aim to inform government officials, businesses, and the general public about important issues. These organizations can be independent or affiliated with universities, governments, or political parties. Some well-known think tanks include the Brookings Institution, Carnegie Endowment for International Peace, and the Heritage Foundation. Their work often involves publishing reports, hosting events, and engaging in public discussions to promote their findings.
