In political science and sociology, a cleavage is a historically determined social or cultural line which divides citizens within a society into groups with differing political interests, resulting in political conflict among these groups. Social or cultural cleavages thus become political cleavages once they get politicized as such. Cleavage theory accordingly argues that political cleavages predominantly determine a country's party system as well as the individual voting behavior of citizens, dividing them into voting blocs. It is distinct from other common political theories on voting behavior in the sense that it focuses on aggregate and structural patterns instead of individual voting behaviors.
Classical cleavage theories have generally been focused on the persistence of dominant conflicts within national political systems over the course of history. Political sociologists Seymour Martin Lipset and Stein Rokkan (1967) for example used the term in their often cited essay on cleavage structures in West European politics. In their essay, the authors argue how the European party systems at their time of writing were still largely based on the social and cultural cleavages that characterized European societies a century earlier. They therefore argue that these 'frozen party systems' can be seen as political expressions of historically determined societal divisions.
Although some authors have claimed that the cleavages in Lipset and Rokkan's theory are still dominant for contemporary voting behaviors in Western Europe, others have argued that these traditional cleavages have become less important and new conflict lines have emerged. Conflicts that have emerged around several new political cleavages are for example cultural, such as conflicts over integration and multiculturalism, or environmental, such as ongoing politics over climate change.
The cleavages in Lipset and Rokkan's classical theory have its origins in two developments in 19th century Western Europe. On the one hand European societies at the time saw a period of so-called national revolutions.

Centrism is a political outlook or position involving acceptance or support of a balance of social equality and a degree of social hierarchy while opposing political changes that would result in a significant shift of society strongly to the left or the right. Both centre-left and centre-right politics involve a general association with centrism that is combined with leaning somewhat to their respective sides of the left–right political spectrum.
A party system is a concept in comparative political science concerning the system of government by political parties in a democratic country. The idea is that political parties have basic similarities: they control the government, have a stable base of mass popular support, and create internal mechanisms for controlling funding, information and nominations. The party system concept was originated by European scholars studying the United States, especially James Bryce, Giovanni Sartori and Moisey Ostrogorsky, and has been expanded to cover other democracies.
Political polarization (spelled polarisation in British English) is the divergence of political attitudes away from the center, towards ideological extremes. Most discussions of polarization in political science consider polarization in the context of political parties and democratic systems of government. In two-party systems, political polarization usually embodies the tension of its binary political ideologies and partisan identities.
Poor decisions and selfish behaviors give rise to seemingly intractable global problems, such as the lack of transparency in democratic processes, the spread of conspiracy theories, and the rise in greenhouse gas emissions. However, people are more predict ...
