Explanation:
The annual report published by the University of Pennsylvania on the quality of think tanks in the world classifies them as public policy research organizations capable of making recommendations to political acts.
The role of think tanks, according to the same report, is to fill knowledge gaps to improve public policies in areas important to collective well-being such as the environment, immigration, poverty, economics and public health.
To influence policy decisions and public opinion, think tanks bring together experts who develop studies on particular topics and publish the results. Their performance may either be more technical, seeking exemption in recommendations, or assuming religious or ideological assumptions - be they liberal, conservative or social-democratic.
