Think tanks A think tank (also called a policy institute ) is an organization, institute, corporation, or group that conducts research and engages in advocacy in public policy.  Many think tanks are non-profit organizations, which some countries such as the United States and Canada provide with tax exempt status. While many think tanks are funded by governments, interest groups, or businesses, some think tanks also derive income from consulting or research work related to their mandate.  In some cases, think tanks are little more than public relations fronts, usually headquartered in state or national seats of government and generating self-serving scholarship that serves the advocacy goals of their industry sponsors. Of course, some think tanks are more legitimate than that.
