Think tanks can be defined as "institutions affiliated with universities, governments, advocacy groups, foundations, non-governmental organizations, and businesses that generate public policy research, analysis, and activity." [Harvard Kennedy School, Think Tank Search: Inclusion Policy]. Think tanks may be partisan or non-partisan, and vary widely by ideological perspectives, sources of funding, topical emphasis, and prospective consumers. Think tanks are playing an increasing role in influencing the development of government policies.
