Segnalazione bibliografica. Autori: Brad Verhulst, Lindon J. Eaves, Peter K. Hatemi American Journal of Political Science 56(1), 34-51 (January 2012) Abstract The assumption in the personality and politics literature is that a person's personality motivates them to develop certain political attitudes later in life. This assumption is founded on the simple correlation between the two constructs and the observation that personality traits are genetically influenced and develop in infancy, whereas political preferences develop later in life. Work in psychology, behavioral genetics, and recently political science, however, has demonstrated that political preferences also develop in childhood and are equally influenced by genetic factors. These findings cast...

Segnalazione bibliografica. Autori: Kevin Smith, John R. Alford, Peter K. Hatemi, Lindon J. Eaves, Carolyn Funk, John R. Hibbing. American Journal of Political Science 56(1), 17-33 (January 2012) Abstract Evidence that political attitudes and behavior are in part biologically and even genetically instantiated is much discussed in political science of late. Yet the classic twin design, a primary source of evidence on this matter, has been criticized for being biased toward finding genetic influence. In this article, we employ a new data source to test empirically the alternative, exclusively environmental, explanations for ideological similarities between twins. We find little support for these explanations and...

Segnalazione bibliografica. British Journal of Political Science (2011), 41: 363-387 Autore: Philipp Rehm Abstract Why has the American political landscape grown more partisan since the 1970s? This article provides a novel account of the determinants of partisanship. The author argues that partisanship is not only shaped by the traditionally suggested socio-economic factors, but also by the uncertainty of future income (risk exposure): rich individuals facing a high degree of risk exposure (or poor people facing low risk exposure) are ‘cross-pressured’; while their income suggests that they should identify with the Republicans, their income prospects make them sympathize with the Democrats. These two traits have overlapped increasingly since the 1970s. Those...

Although political scandals receive unprecedented attention in the contemporary media, the knowledge of political scientists regarding the consequences of such scandals remains limited. On the basis of two nationally representative survey experiments, we investigate whether the impact of scandals depends on the traits of the politicians involved. We find substantial evidence that politicians are particularly punished for political-ideological hypocrisy, while there is less evidence that gender stereotypes matter. We also show that voters evaluate scandals in the personal lives of politicians in a highly partisan manner – other-party voters punish a politician substantially harsher than same-party voters. Interestingly, voters show no gender bias in their candidate evaluations.

Although many studies of clientelism focus exclusively on vote buying, political machines often employ diverse portfolios of strategies. We provide a theoretical framework and formal model to explain how and why machines mix four clientelist strategies during elections: vote buying, turnout buying, abstention buying, and double persuasion. Machines tailor their portfolios to the political preferences and voting costs of the electorate. They also adapt their mix to at least five contextual factors: compulsory voting, ballot secrecy, political salience, machine support, and political polarization. Our analysis yields numerous insights, such as why the introduction of compulsory voting may increase vote buying, and why enhanced ballot secrecy may increase turnout buying and abstention buying. Evidence from various countries is consistent with our predictions and suggests the need for empirical studies to pay closer attention to the ways in which machines combine clientelist strategies.
