criticized by researchers such as Enrique Mendizabal and Goran Buldioski, Director of the Think Tank Fund, assisted by the Open Society Institute. 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 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
