think tank

History

According to historian Jacob Soll, while the term "think tank" is modern, with its origin "traced to the humanist academies and scholarly networks of the 16th and 17th centuries," evidence shows that, "in Europe, the origins of think tanks go back to the 800s when emperors and kings began arguing with the Catholic Church about taxes. A tradition of hiring teams of independent lawyers to advise monarchs about their financial and political prerogatives against the church spans from Charlemagne all the way to the 17th century, when the kings of France were still arguing about whether they had the right to appoint bishops and receive a cut of their income."

Soll cites as an early example the Académie des frères Dupuy, created in Paris around 1620 by the brothers Pierre and Jacques Dupuy and also known after 1635 as the cabinet des frères Dupuy. The Club de l'Entresol, active in Paris between 1723 and 1731, was another prominent example of an early independent think tank focusing on public policy and current affairs, especially economics and foreign affairs.

19th century

Several major current think tanks were founded in the 19th century. The Royal United Services Institute was founded in 1831 in London, and the Fabian Society in 1884.

20th century

The oldest United States–based think tank, the Carnegie Endowment for International Peace, was founded in Washington, D.C., in 1910 by philanthropist Andrew Carnegie. Carnegie charged trustees to use the fund to "hasten the abolition of international war, the foulest blot upon our civilization." The Brookings Institution was founded shortly thereafter in 1916 by Robert S. Brookings and was conceived as a bipartisan "research center modeled on academic institutions and focused on addressing the questions of the federal government."

After 1945, the number of policy institutes increased, with many small new ones forming to address Cold War geopolitics and post-war reconstruction, aiming to express various issues and policy agendas. Until the 1940s, most think tanks were known only by the name of the institution. During the Second World War, think tanks were often referred to as "brain boxes".

Before the 1950s, the phrase "think tank" did not refer to organizations. From its first appearances in the 1890s up to the 1950s, the phrase was most commonly used in American English to colloquially refer to the braincase or especially in a pejorative context to the human brain itself when commenting on an individual's failings (in the sense that something was wrong with that person's "think tank"). Around 1958, the first organization to be regularly described in published writings as "the Think Tank" (note the title case and the use of the definite article) was the Center for Advanced Study in the Behavioral Sciences. However, the Center does not count itself as and is not perceived to be a think tank in the contemporary sense. During the 1960s, the phrase "think tank" was attached more broadly to meetings of experts, electronic computers, and independent military planning organizations. The prototype and most prominent example of the third category was the RAND Corporation, which was founded in 1946 as an offshoot of Douglas Aircraft and became an independent corporation in 1948. In the 1970s, the phrase became more specifically defined in terms of RAND and others. During the 1980s and 1990s, the phrase evolved again to arrive at its broader contemporary meaning of an independent public policy research institute.

For most of the 20th century, such institutes were found primarily in the United States, along with much smaller numbers in Canada, the United Kingdom, and Western Europe. Although think tanks had also existed in Japan for some time, they generally lacked independence, having close associations with government ministries or corporations. There has been a veritable proliferation of "think tanks" around the world that began during the 1980s as a result of globalization, the end of the Cold War, and the emergence of transnational problems. Two-thirds of all the think tanks that exist today were established after 1970 and more than half were established since 1980.

21st century

As of 2014, there were more than 11,000 of these institutions worldwide. Many of the more established think tanks, created during the Cold War, are focused on international affairs, security studies, and foreign policy.

The median think tank publishes 138 articles a year, albeit there is substantial variation, with the Brookings Institution having published 3,880 reports in 2020 alone. Other prolific publishers include the Wilson Center or the CSIS.

Types

Think tanks vary by ideological perspectives, sources of funding, topical emphasis and prospective consumers. Funding may also represent who or what the institution wants to influence; in the United States, for example, "Some donors want to influence votes in Congress or shape public opinion, others want to position themselves or the experts they fund for future government jobs, while others want to push specific areas of research or education."

McGann distinguishes think tanks based on independence, source of funding and affiliation, grouping think tanks into autonomous and independent, quasi-independent, government affiliated, quasi-governmental, university affiliated, political-party affiliated or corporate.

A new trend, resulting from globalization, is collaboration between policy institutes in different countries. For instance, the Carnegie Endowment for International Peace operates offices in Washington, D.C., Beijing, Beirut, Brussels and formerly in Moscow, where it was closed in April 2022.

The Think Tanks and Civil Societies Program (TTCSP) at the University of Pennsylvania, led by James McGann, annually rated policy institutes worldwide through 2021 in a number of categories and presented its findings in the Global Go-To Think Tanks rating index. However, this method of the study and assessment of policy institutes has been criticized by researchers such as Enrique Mendizabal and Goran Buldioski, Director of the Think Tank Fund, assisted by the Open Society Institute. As the TTCSP ended its operations in 2021, the platform ThinkTankAlert started ranking think tanks globally based on their inter-citation patterns in 2025.

Activities

Think tanks may attempt to broadly inform the public by holding conferences to discuss issues which they may broadcast; encouraging scholars to give public lectures, testifying before committees of governmental bodies; publishing and widely distributing books, magazines, newsletters or journals; creating mailing lists to distribute new publications; and engaging in social media.

Think tanks may privately influence policy by having their members accept bureaucratic positions, having members serve on political advisory boards, inviting policy-makers to events, allowing individuals to work at the think tank; employing former policy-makers; or preparing studies for policy makers.

Governmental theory

The role of think tanks has been conceptualized through the lens of social theory. German political scientist Dieter Plehwe argues that think tanks function as knowledge actors within a network of relationships with other knowledge actors. Such relationships include citing academics in publications or employing them on advisory boards, as well as relationships with media, political groups and corporate funders. They argue that these links allow for the construction of a discourse coalition with a common aim, citing the example of deregulation of trucking, airlines, and telecommunications in the 1970s. Plehwe argues that this deregulation represented a discourse coalition between the Ford Motor Company, FedEx, neo-liberal economists, the Brookings Institution and the American Enterprise Institute.

Elite theory considers how an "elite" influences the actions of think tanks and potentially bypasses the political process, analysing the social background and values of those who work in think tanks. Pautz criticizes this viewpoint because there is in practice a variety of viewpoints in think tanks and argues it dismisses the influence that ideas can have.

Advocacy

In some cases, corporate interests, military interests and political groups have found it useful to create policy institutes, advocacy organizations, and think tanks. For example, The Advancement of Sound Science Coalition was formed in the mid-1990s to dispute research finding an association between second-hand smoke and cancer. Military contractors may spend a portion of their tender on funding pro-war think tanks. According to an internal memorandum from Philip Morris Companies referring to the United States Environmental Protection Agency (EPA), "The credibility of the EPA is defeatable, but not on the basis of ETS [environmental tobacco smoke] alone,... It must be part of a larger mosaic that concentrates all the EPA's enemies against it at one time."

According to the progressive media watchdog Fairness & Accuracy in Reporting, both left-wing and right-wing policy institutes are often quoted and rarely identified as such. The result is that think tank "experts" are sometimes depicted as neutral sources without any ideological predispositions when, in fact, they represent a particular perspective. In the United States, think tank publications on education are subjected to expert review by the National Education Policy Center's "Think Twice" think tank review project.

A 2014 New York Times report asserted that foreign governments buy influence at many United States think tanks. According to the article: "More than a dozen prominent Washington research groups have received tens of millions of dollars from foreign governments in recent years while pushing United States government officials to adopt policies that often reflect the donors' priorities."

Global think tanks

African think tanks

Ghana's first president, Kwame Nkrumah, set up various state-supported think tanks in the 1960s. By the 1990s, a variety of policy research centers sprang up in Africa set up by academics who sought to influence public policy in Ghana.

One such think tank was The Institute of Economic Affairs, Ghana, which was founded in 1989 when the country was ruled by the Provisional National Defence Council. The IEA undertakes and publishes research on a range of economic and governance issues confronting Ghana and Sub-Saharan Africa. It has also been involved in bringing political parties together to engage in dialogue. In particular it has organised Presidential debates every election year since the Ghanaian presidential election, 1996.

Notable think tanks in Ghana include:

Asian think tanks

Afghanistan has a number of think tanks that are in the form of governmental, non-governmental, and corporate organizations.

Bangladesh has a number of think tanks that are in the form of governmental, non-governmental, and corporate organizations.

In China a number of think tanks are sponsored by governmental agencies such as Development Research Center of the State Council, but still retain sufficient non-official status to be able to propose and debate ideas more freely. In January 2012, the first non-official think tank in mainland China, South Non-Governmental Think-Tank, was established in the Guangdong province. In 2009 the China Center for International Economic Exchanges was founded.

In Hong Kong, early think tanks established in the late 1980s and early 1990s focused on political development, including the first direct Legislative Council members election in 1991 and the political framework of "One Country, Two Systems", manifested in the Sino-British Joint Declaration. After the transfer of sovereignty to China in 1997, more think tanks were established by various groups of intellectuals and professionals. They have various missions and objectives including promoting civic education; undertaking research on economic, social and political policies; and promoting "public understanding of and participation in the political, economic, and social development of the Hong Kong Special Administrative Region".

Think tanks in Hong Kong include:

India has the world's second-largest number of think tanks. Most are based in New Delhi, and a few are government-sponsored. There are few think tanks that promote environmentally responsible and climate resilient ideas like Centre for Science and Environment, Centre for Policy Research and World Resources Institute. There are other prominent think tanks like Observer Research Foundation, Tillotoma Foundation, and Centre for Civil Society.

In Mumbai, Strategic Foresight Group is a global think tank that works on issues such as water diplomacy, peace and conflict and foresight (futures studies). Think tanks with a development focus include those like the National Centre for Cold-chain Development ('NCCD'), which serve to bring an inclusive policy change by supporting the Planning Commission and related government bodies with industry-specific inputs – in this case, set up at the behest of the government to direct cold chain development. Some think tanks have a fixed set of focus areas and they work towards finding out policy solutions to social problems in the respective areas.

European think tanks

Brussels hosts most of the European Institutions, hence a large number of international think tanks are based there. Notable think tanks are Bruegel, the Centre for European Policy Studies (CEPS), Centre for the New Europe (CNE), the European Centre of International Political Economy (ECIPE), the European Policy Centre (EPC), the Friends of Europe, the Global Governance Institute (GGI), Liberales, and Sport and Citizenship, among others.

Bulgaria has a number of think tanks providing expertise and shaping policies, including Institute of Modern Politics.

The European Values Think-Tank

The Prague Security Studies Institute (PSSI)

CEPOS is a classic libertarian/free-market conservative think tank in Denmark.

Finland has several small think tanks that provide expertise in very specific fields. Notable think tanks include:

Åland Islands Peace Institute

Demos Helsinki

European Centre of Excellence for Countering Hybrid Threats (Hybrid CoE)

Crisis Management Initiative (CMI)

Research Institute of the Finnish Economy (Etla)

Finnish Institute of International Affairs

In addition to specific independent think tanks, the largest political parties have their own think tank organizations. This is mainly due to support granted by state for such activity. The corporate world has focused their efforts to central representative organization Confederation of Finnish Industries, which acts as think tank in addition to negotiating salaries with workers unions. Furthermore, there is the Finnish Business and Policy Forum (Elinkeinoelämän valtuuskunta, EVA). Agricultural and regional interests, associated with The Central Union of Agricultural Producers and Forest Owners (Maa- ja metsätaloustuottajain Keskusliitto, MTK) and the Centre Party, are researched by Pellervo Economic Research (Pellervon taloustutkimus, PTT). The Central Organisation of Finnish Trade Unions (Suomen Ammattiliittojen Keskusjärjestö, SAK) and the Social Democratic Party are associated with the Labour Institute for Economic Research (Palkansaajien tutkimuslaitos, PT). Each of these organizations often release forecasts concerning the national economy.

Oceanian think tanks

Most Australian think tanks are based at universities – for example, the Melbourne Institute – or are government-funded – for example, the Productivity Commission or the CSIRO.

Private sources fund about 20 to 30 "independent" Australian think tanks. The best-known of these think tanks play a much more limited role in Australian public and business policy-making than do their equivalents in the United States. However, in the past decade the number of think tanks has increased substantially. Prominent think tanks on the right include the Centre for Independent Studies, the Sydney Institute, the Lowy Institute, and the Institute of Public Affairs. Prominent think tanks on the left include the McKell Institute, Per Capita, the Australia Institute, and the Centre for Policy Development.

Think tanks in Australia include:

Think tanks based in New Zealand include:

North American think tanks

Canada has many notable think tanks (listed in alphabetical order). Each has specific areas of interest with some overlaps.

CIDAC – The Center of Research for Development (Centro de Investigación para el Desarrollo, Asociación Civil) is a not-for-profit think tank that undertakes research and proposes viable policy options for Mexico's economic and democratic development. The organization seeks to promote open, pluralistic debate pursuing: the Rule of Law & Democracy, market economics, social development, and strengthening Mexico-United States relations.

CIDE – The Center of Research and Economics Teaching (Centro de Investigación y Docencia Económicas) is a think tank institute focussing on "public policies", "public choice", "democracy", and "economy".

As the classification is most often used today, the oldest American think tank is the Carnegie Endowment for International Peace, founded in 1910. The Institute for Government Research, which later merged with two organizations to form the Brookings Institution, was formed in 1916. Other early twentieth century organizations now classified as think tanks include the Hoover Institution (1919), The Twentieth Century Fund (1919, and now known as the Century Foundation), the National Bureau of Economic Research (1920), the Council on Foreign Relations (1921), and the Social Science Research Council (1923). The Great Depression and its aftermath spawned several economic policy organizations, such as the National Planning Association (1934), the Tax Foundation (1937), and the Committee for Economic Development (1943).

In collaboration with the Douglas Aircraft Company, the Air Force set up the RAND Corporation in 1946 to develop weapons technology and strategic defense analysis.

The Hudson Institute is a conservative American think tank founded in 1961 by futurist, military strategist, and systems theorist Herman Kahn and his colleagues at the RAND Corporation. Recent members include Mike Pompeo, the former secretary of state under Donald Trump who joined in 2021.

More recently, progressive and liberal think tanks have been established, most notably the Center for American Progress and the Center for Research on Educational Access and Leadership (CREAL). The organization has close ties to former United States President Barack Obama and other prominent Democrats.

South American think tanks

Research done by Enrique Mendizabal shows that South American think tanks play various roles depending on their origins, historical development and relations to other policy actors. In this study, Orazio Bellettini from Grupo FARO suggests that they:

Seek political support for policies.

Legitimize policies. This has been clearer in Ecuador, Bolivia and Peru. New governments in Ecuador and Peru have approached policy institutes for support for already defined policies. In Bolivia, the government of Evo Morales has been working with Non-Government Organizations (NGOs) and other research institutes to do the same. However, in Chile, many think tanks during the 1990s seemed to endorse and maintain the legitimacy of policies implemented during the previous decade by the military dictatorship headed by Pinochet.

Act as Spaces for debate. In this case think tanks serve as sounding boards for new policies. In Chile, during the Pinochet dictatorship, many left wing intellectuals and researchers found 'asylum' in think tanks. In Ecuador, think tanks are seen as spaces where politicians can test the soundness of their policies and government plans.

Provide financial channels for political parties or other interest groups. In Ecuador and Bolivia, German foundations have been able to provide funds to think tanks that work with certain political parties. This method has provided support to the system as a whole rather than individual CSOs.

Supply expert staff of policy-makers. In Peru after the end of the Fujimori regime, and in Chile after the fall of Pinochet, think tank staff left to form part of the new governments. In the United States, the role of major think tanks is precisely that: host scholars for a few months or years and then lose them to government employ.

How a policy institute addresses these largely depends on how they work, their ideology vs. evidence credentials, and the context in which they operate including funding opportunities, the degree and type of competition they have and their staff.

Transcontinental countries (Asia-Europe)

According to a 2020 report, there are 32 think tanks or similar institutions in Armenia.

The government closed the Noravank Foundation, a government-affiliated think tank, in 2018 after almost two decades of operation. However, other think tanks continue to operate, include the Caucasus Institute, the Caucasus Research Resource Center-Armenia (CRRC-Armenia) (which publishes the "Caucasus Barometer" annual public opinion survey of the South Caucasus, the "Enlight" Public Research Center, and the AMBERD research center at the Armenian State University of Economics.

According to research done by the University of Pennsylvania, there are a total of 12 think tanks in Azerbaijan.

The Center for Economic and Social Development, or CESD; in Azeri, Azerbaijan, İqtisadi və Sosial İnkişaf Mərkəzi (İSİM) is an Azeri think tank, non-profit organization, NGO based in Baku, Azerbaijan. The center was established in 2005. CESD focuses on policy advocacy and reform, and is involved with policy research and capacity building.

The Economic Research Center (ERC) is a policy-research oriented non-profit think tank established in 1999 with a mission to facilitate sustainable economic development and good governance in the new public management system of Azerbaijan. It seeks to do this by building favorable interactions between the public, private and civil society and working with different networks both in local (EITI NGO Coalition, National Budget Group, Public Coalition Against Poverty, etc.) and international levels (PWYP, IBP, ENTO, ALDA, PASOS, WTO NGO Network etc.).

The Center for Strategic Studies under the President of Azerbaijan is a governmental, non-profit think tank founded in 2007. It focuses on domestic and foreign policy.

According to the Foreign Policy Research Institute, Russia has 112 think tanks, while Russian think tanks claimed four of the top ten spots in 2011's "Top Thirty Think Tanks in Central and Eastern Europe".
