‘Political Cleavages and Political Realignment in Norway: The New Politics Thesis Reexamined’, Scandinavian Political Studies 9, 1986: 235-263. Oddbjørn Knutsen Abstract The question of political realignment and dealignment in advanced industrial democracies has been the subject of considerable comparative analysis. In this study the literature regarding the 'new politics' is taken as the point of departure to examine the relative importance of different political cleavages. The traditional socio-structural cleavages in the Rokkan/Lipset model for political polarisation in industrial society are contrasted with an extended value-based cleavage model which includes five different sets of value orientations. Using data from a nation-wide Norwegian survey conducted in 1981, the findings indicate that although there is a clear tendency towards a generation-based structural dealignment process in accordance with 'new politics' literature, the thesis that the materialist/post-materialist value orientations have taken over as the dominant polarisation pattern in Norway is not generally confirmed. The old left-right value-based conflicts which is called left-right materialist value orientations - appears to be of greater importance, even in the post-war generations.
