characterized the ancestral environment and not the much larger political structures in today's world. This is argued to explain many important features and systematic cognitive biases of current politics. Overview Political science is a social study concerning the allocation and transfer of power in decision making, the roles and systems of governance including governments and international organizations, political behaviour, and public policies. It measures the success of governance and specific policies by examining many factors, including stability, justice, material wealth, peace, and public health. Some political scientists seek to advance positive theses (which attempt to describe how things are, as opposed to how they should be) by analysing politics; others advance normative theses, such as by making specific policy recommendations. The study of politics and policies can be closely connected—for example, in comparative analyses of which types of political institutions tend to produce certain types of policies. Political science provides analysis and predictions about political and governmental issues. Political scientists examine the processes, systems and political dynamics of countries and regions of the world, often to raise public awareness or to influence specific governments. Political scientists may provide the frameworks from which journalists, special interest groups, politicians, and the electorate analyze issues. According to Chaturvedy, Country-specific studies Political scientists may study political phenomena within one specific country; for example, they may study just the politics of the United States or just the politics of China. Political scientists look at a variety of data, including constitutions, elections, public opinion, and public policy, foreign policy, legislatures, and judiciaries. Political scientists will often focus on the politics of their own country; for example, a political scientist from Indonesia may become an expert in the politics of Indonesia. Anticipating crises The theory of political transitions, and the methods of analyzing and anticipating crises, form an important part of political science. Several general indicators of crises and methods were proposed for anticipating critical transitions. Among them, one statistical indicator of crisis, a simultaneous increase of variance and correlations in large groups, was proposed for crisis anticipation and may be successfully used in various areas. Its applicability for early diagnosis of political crises was demonstrated by the analysis of the prolonged stress period preceding the 2014 Ukrainian economic and political crisis. There was a simultaneous increase in the total correlation between the 19 major public fears in the Ukrainian society (by about 64%) and in their
