My book, The Simple Art of Voting. The Cognitive Shortcuts of Italian Voters, just came out with Oxford University Press. 

Voting distills a complex decision into a deceptively simple action. During campaign seasons, the electorate faces a messy tangle of parties, leaders, and issues. How is it possible for voters to unravel it all? How do they perceive and evaluate the political landscape? How, in short, do voters choose?

Not only is voting a complex choice, but voters themselves also vary widely in their degree of interest, and involvement in politics. Too often, though, scholars have ignored this variety by focusing on a mythic "average voter."

This book focuses on how choices are made given the cognitive limitations of the human mind and the environment in which decision-making takes place. Drawing on recent advances in the study of cognitive psychology, decision-making, and political cognition, Baldassarri provides a careful empirical examination of the strategies voters actually use to manage the complexity of political choice. 

This is a field-advancing study - the first to investigate systematically the use of simplifying heuristics to cope with the complexities of choice in a multi-party system. It is a rare example of creativity that enlarges rather than rejects the insights of previous research.
