THE IDEA BROKERS: THE IMPACT OF THINK TANKS ON BRITISH GOVERNMENT

Although there are few think tanks in Britain they have been credited with considerable influence on government policies since the late 1970s. This article charts their recent history, distinguishing between larger, 'establishment' bodies like the Policy Studies Institute and smaller, more politically partisan bodies such as the Centre for Policy Studies; generally the latter have enjoyed greater influence. It identifies the distinctive characteristics of these bodies–their ideological orientation, their concentration on élite opinion formers, their short to medium-term horizons, their emphasis on originality and publicity. Think tanks face tactical dilemmas when pressing their views on Britain's comparatively closed system of government, in particular their choice between insider and outsider forms of persuasion; the tension between proximity to ministers and intellectual autonomy; and their advantages to politicians as deniable sources that can float new ideas, which can be counter-balanced by politicians' fluctuating appetite for radical ideas. As a case study the article examines the relations enjoyed by the Institute of Economic Affairs and the Centre for Policy Studies with Mrs Thatcher's government, and particularly the evolution of a potent network of influence embracing ministers, special advisers and backbenchers. Finally it considers the dangers of an overemphasis on novelty at the expense of feasibility, and the danger of burnout in the smaller think tanks dangers mitigated by the continuous turnover that operates in the world of think tanks.
