Collective Decisions and Voting


Book Description

Voting is often the most public and visible example of mass collective decision-making. But how do we define a collective decision? And how do we classify and evaluate the modes by which collective decisions are made? This book examines these crucial ques




Democratic Reason


Book Description

Individual decision making can often be wrong due to misinformation, impulses, or biases. Collective decision making, on the other hand, can be surprisingly accurate. In Democratic Reason, Hélène Landemore demonstrates that the very factors behind the superiority of collective decision making add up to a strong case for democracy. She shows that the processes and procedures of democratic decision making form a cognitive system that ensures that decisions taken by the many are more likely to be right than decisions taken by the few. Democracy as a form of government is therefore valuable not only because it is legitimate and just, but also because it is smart. Landemore considers how the argument plays out with respect to two main mechanisms of democratic politics: inclusive deliberation and majority rule. In deliberative settings, the truth-tracking properties of deliberation are enhanced more by inclusiveness than by individual competence. Landemore explores this idea in the contexts of representative democracy and the selection of representatives. She also discusses several models for the "wisdom of crowds" channeled by majority rule, examining the trade-offs between inclusiveness and individual competence in voting. When inclusive deliberation and majority rule are combined, they beat less inclusive methods, in which one person or a small group decide. Democratic Reason thus establishes the superiority of democracy as a way of making decisions for the common good.




Collective Decisions and Voting


Book Description

When one thinks about how collective decisions are made, voting is the method that comes naturally to mind. But other methods such as random process and consensus are also used. This book explores just what a collective decision is, classifies the methods of making collective decisions, and identifies the advantages and disadvantages of each method. Classification is the prelude to evaluation. What are the characteristics of a method of making collective decisions, the book asks, that permit us to describe a collective decision as good? The second part of the book is detailed exploration of voting: the dimensions in which voting situations differ, the origins and logic of majority rule, the frequency of cycles in voting, the Arrow and Gibbard-Satterthwaite theorems, criteria for ways of cutting through cycles and the application of these criteria to a variety of rules, voting over continuums, proportional representation, and voting rules that take account of intensities of preferences. Relatively unknown methods of voting give voting a much greater potential than is generally recognized. Collective Decisions and Voting is essential reading for everyone with an interest in voting theory and in how public choices might be made.




Collective Preference and Choice


Book Description

A study of the classical aggregation problems that arise in social choice theory, voting theory, and group decision-making under uncertainty.




Rational Choice, Collective Decisions, and Social Welfare


Book Description

An examination of the phenomenon of social cooperation failure, even amongst a group of rational individuals.




Handbook of Computational Social Choice


Book Description

The rapidly growing field of computational social choice, at the intersection of computer science and economics, deals with the computational aspects of collective decision making. This handbook, written by thirty-six prominent members of the computational social choice community, covers the field comprehensively. Chapters devoted to each of the field's major themes offer detailed introductions. Topics include voting theory (such as the computational complexity of winner determination and manipulation in elections), fair allocation (such as algorithms for dividing divisible and indivisible goods), coalition formation (such as matching and hedonic games), and many more. Graduate students, researchers, and professionals in computer science, economics, mathematics, political science, and philosophy will benefit from this accessible and self-contained book.




Democratic Decision-making


Book Description

This book provides a practical guide to how groups of people, everywhere, from the local village council to the United Nations Security Council, can best make collective decisions. By comparing the many voting procedures used in democratic decision-making, it explains why win-or-lose binary voting can be inaccurate and divisive, while the more inclusive preferential points system of voting can be so much more accurate and, therefore, more democratic; indeed, it is a win-win methodology. The text, essential reading for anyone interested in fair and participatory collective decision-making, also compares the most common electoral systems.




A Behavioral Theory of Elections


Book Description

Most theories of elections assume that voters and political actors are fully rational. This title provides a behavioral theory of elections based on the notion that all actors - politicians as well as voters - are only boundedly rational.




Honeybee Democracy


Book Description

How honeybees make collective decisions—and what we can learn from this amazing democratic process Honeybees make decisions collectively—and democratically. Every year, faced with the life-or-death problem of choosing and traveling to a new home, honeybees stake everything on a process that includes collective fact-finding, vigorous debate, and consensus building. In fact, as world-renowned animal behaviorist Thomas Seeley reveals, these incredible insects have much to teach us when it comes to collective wisdom and effective decision making. A remarkable and richly illustrated account of scientific discovery, Honeybee Democracy brings together, for the first time, decades of Seeley's pioneering research to tell the amazing story of house hunting and democratic debate among the honeybees. In the late spring and early summer, as a bee colony becomes overcrowded, a third of the hive stays behind and rears a new queen, while a swarm of thousands departs with the old queen to produce a daughter colony. Seeley describes how these bees evaluate potential nest sites, advertise their discoveries to one another, engage in open deliberation, choose a final site, and navigate together—as a swirling cloud of bees—to their new home. Seeley investigates how evolution has honed the decision-making methods of honeybees over millions of years, and he considers similarities between the ways that bee swarms and primate brains process information. He concludes that what works well for bees can also work well for people: any decision-making group should consist of individuals with shared interests and mutual respect, a leader's influence should be minimized, debate should be relied upon, diverse solutions should be sought, and the majority should be counted on for a dependable resolution. An impressive exploration of animal behavior, Honeybee Democracy shows that decision-making groups, whether honeybee or human, can be smarter than even the smartest individuals in them.




The Origins of Collective Decision Making


Book Description

In The Origins of Collective Decision Making, Andy Blunden identifies three paradigms of collective decision making – Counsel, Majority and Consensus, discovers their origins in traditional, medieval and modern times, and traces their evolution over centuries up to the present. The study reveals that these three paradigms have an ethical foundation, deeply rooted in historical experiences. The narrative takes the reader into the very moments when individual leaders and organisers made the crucial developments in white heat of critical moments in history, such as the English Revolution of the 1640s, the Chartist Movement of the 1840s and the early Civil Rights Movement of the 1960s. This history provides a valuable resource for resolving current social movement conflict over decision making.
