From Policy Concepts in 1000 Words: Multiple Streams Analysis:
‘Ideas’ are the beliefs we develop and use to understand and interpret the world. Some beliefs are so deeply ingrained in our psyche that we generally take them for granted. Others are more visible – our beliefs about policy problems help us argue for particular solutions. Indeed, ‘policy solution’ is closer to the intuitive meaning of ‘I have an idea’. Kingdon grapples with this dual role for (or meaning of) ‘ideas’ by considering how policy solutions are received within government or wider policy networks. His starting point is the phrase ‘an idea whose time has come’, which implies ‘an irresistible movement that sweeps over our politics and our society, pushing aside everything that might stand in its path’. He argues that such notions are misleading because they ignore the conditions that have to be satisfied – during a brief ‘window of opportunity’ – before a policy will change significantly. Three separate ‘streams’ must come together at the same time:
Problem stream – attention lurches to a policy problem. Problems are policy issues which are deemed to require attention. There are no objective indicators to determine which problems deserve attention, and perceptions of problems can change quickly. Problems get attention based on how they are ‘framed’ or defined by participants who compete for attention – using evidence to address uncertainty and persuasion to address ambiguity. In some cases, issues receive attention because of a crisis or change in the scale of the problem. Only a tiny fraction of problems receive policymaker attention. Getting attention is a major achievement which must be acted upon quickly, before attention shifts elsewhere. This might be achieved by demonstrating that a well thought out solution already exists.
Policy stream – a solution to that problem is available. While attention lurches quickly from issue to issue, viable solutions involving major policy change take time to develop. Kingdon describes ideas in a ‘policy primeval soup’, evolving as they are proposed by one actor then reconsidered and modified by a large number of participants (who may have to be ‘softened up’ to new ideas). To deal with the disconnect between lurching attention and slow policy development, they develop widely-accepted solutions in anticipation of future problems, then find the right time to exploit or encourage attention to a relevant problem.
Politics stream – policymakers have the motive and opportunity to turn it into policy. They have to pay attention to the problem and be receptive to the proposed solution. They may supplement their own beliefs with their perception of the ‘national mood’ and the feedback they receive from interest groups and political parties. In some cases, only a change of government may be enough to provide that motive.
