Think tanks are a common term for non-governmental or not-for-profit institutions, often affiliated with a university, which conduct research. Think tanks often have a specific focus to their work, for instance focusing on environmental research and public policy. Think tanks may be engaged in advocacy and may have an implicit or explicit political bias, and so it is important when using think tank materials to assess the quality of the research and not rely solely on their work to the exclusion of scholarly resources.
