Culture Wars,Secular Realignment,and the Gender Gap in Party Identification

Changes in the U.S. partisan balance over the past decade are often attributed to the enhanced political salience of cultural issues. Yet as white men have continued to become more Republican in recent years, white women increasingly identify with the Democrats. To the extent that cultural issues are influencing this partisan change, men and women must be responding differently to this cultural agenda. Using a pooled ANES data set from 1988 through 2000, I explore the extent to which cultural values are responsible for this gender realignment. Findings suggest that salient cultural issues influence the partisan choices of both men and women, however in somewhat different ways. For women, the issues themselves—reproductive rights, female equality, and legal protection for homosexuals—have become increasingly important determinants of party identification. For men, the influence of cultural conflict on partisanship is argued to be equally pervasive, albeit less direct.     

Parental Socialization and Rational Party Identification

This article constructs a rational choice model of the intergenerational transmission of party identification. At a given time, identification with a party is the estimate of average future benefits from candidates of that party. Experienced voters constantly update this expectation using political events since the last realignment to predict the future in accordance with Bayes Rule. New voters, however, have no experience of their own. In Bayesian terms, they need prior beliefs. It turns out that under certain specified conditions, these young voters should rationally choose to employ parental experience to help orient themselves to politics. The resulting model predicts several well–known features of political socialization, including the strong correlation between parents' and children's partisanship, the greater partisan independence of young voters, and the tendency of partisan alignments to decay.

I'm Not That Liberal: Explaining Conservative Democratic Identification

The persistence of self-identified conservative Democrats in the electorate is puzzling. Both the ongoing Southern realignment and the recent ideological polarization should have resulted in conservative Democrats changing their party identification to accord with their discrepant ideology. Instead, the number of conservative Democrats, as a percentage of the total electorate, has held steady over the last 20 years. I propose an explanation for this phenomenon that draws upon theories of mass belief systems, as well as an element of recent political reality: the popular stigmatization of the word liberal. I argue that Democrats who are susceptible to elite cues garner positive affect toward the conservative label and negative affect toward the liberal label. They then identify themselves accordingly, regardless of their issue positions.     

Reflections on the prehistory of the Abdālī Afghans

ABSTRACT

The Abdālī Afghans-Pashtuns played a leading role in the creation of the Durrānī polity (est. 1747) – the precursor of present-day Afghanistan. Given their lasting contributions to the process of state formation in Central Asia, it is somewhat surprising that the early history of the Abdālī remains obscure. Nevertheless, authors of recent generations have not been deterred from speculating on the origins of the Abdālī. This article explores the prevailing theories concerning Abdālī prehistory, including the tribe’s purported connection to both the Hephthalites and the Sufi saint Abū A?mad Abdāl, as well as some of the motivations undergirding these theories. It also considers the place of the Abdālī within the Afghan-Pashtun tribal system and ventures to reconcile their Afghan identity with their alleged non-Afghan origins. The present study thus aims to offer a more nuanced understanding of the history of the Abdālī – the most politically prominent group in Afghanistan’s history.     

A Re-examination of the Effects of Biased Lineup Instructions in Eyewitness Identification

A meta-analytic review of research comparing biased and unbiased instructions in eyewitness identification experiments showed an asymmetry; specifically, that biased instructions led to a large and consistent decrease in accuracy in target-absent lineups, but produced inconsistent results for target-present lineups, with an average effect size near zero (Steblay, 1997). The results for target-present lineups are surprising, and are inconsistent with statistical decision theories (i.e., Green & Swets, 1966). A re-examination of the relevant studies and the meta-analysis of those studies shows clear evidence that correct identification rates do increase with biased lineup instructions, and that biased witnesses make correct identifications at a rate considerably above chance. Implications for theory, as well as police procedure and policy, are discussed.     

Suspect/Foil Identification in Actual Crimes and in the Laboratory: A Reality Monitoring Analysis

Four reality monitoring variables were used to discriminate suspect from foil identifications in 183 actual criminal cases. Four hundred sixty-one identification attempts based on five and six-person lineups were analyzed. These identification attempts resulted in 238 suspect identifications and 68 foil identifications. Confidence, automatic processing, eliminative processing and feature use comprised the set of reality monitoring variables. Thirty-five verbal confidence phrases taken from police reports were assigned numerical values on a 10-point confidence scale. Automatic processing identifications were those that occurred “immediately” or “without hesitation.” Eliminative processing identifications occurred when witnesses compared or eliminated persons in the lineups. Confidence, automatic processing and eliminative processing were significant predictors, but feature use was not. Confidence was the most effective discriminator. In cases that involved substantial evidence extrinsic to the identification 43% of the suspect identifications were made with high confidence, whereas only 10% of the foil identifications were made with high confidence. The results of a laboratory study using the same predictors generally paralleled the archival results. Forensic implications are discussed.

Impact of Defense-Only and Opposing Eyewitness Experts on Juror Judgments

Previous research shows that expert testimony on eyewitness memory influences mock-juror judgments. We examined the extent to which opposing expert testimony mitigates the impact of defense-only expert testimony. Participants (N = 497) viewed a video-taped trial involving an eyewitness identification and individually rendered verdicts and evaluated the evidence and the experts. We manipulated the Foils (unbiased vs. biased) and Instructions (unbiased vs. biased) of the lineup and Expert Testimony (no expert vs. defense-only expert vs. opposing experts). Expert testimony did not significantly influence juror judgments, but the opposing expert testimony diminished the credibility of the defense expert in the eyes of the jurors. Results point to the need for further research on conditions that qualify the impact of expert testimony.
