Much of politics takes place in our heads; that is, it is shaped by our ideas, values and assumptions about how society should be organized, and our expectations, hopes and fears about government. Ultimately, what we believe about the society in which we live may be more important than the reality of its power structure, and the actual distribution of resources and opportunities within it. Perception may not only be more important than reality; in practical terms, perception may be reality. This highlights the vital role played by what is called 'political culture'. People's beliefs, symbols and values structure both their attitude to the political process and, crucially, their view of the regime in which they live. However, there is significant disagreement about the nature and role of the political culture, not least over whether it sustains democracy or is aligned with the interests of dominant groups. Others have highlighted concerns about the political culture's (apparently) declining capacity to foster civic engagement and a sense of social belonging.

Long-standing debate about the media's relationship with democracy and styles of governance have been given a fresh twist by the advent of electronic-based 'new' media, while media influence generally has been associated with a growing emphasis in politics on 'news management' and what is called 'spin'. The mass media has affected governance in various ways. These include that they have transformed political leadership and, in the process, reapportioned government power. They have also changed the political culture and, some have warned, contributed to declining respect for politicians and politics in general. Finally, the growing influence of the media is evident in a policy-making process that has to react more rapidly and make sense of a vast amount of information
