The devil is in the detail: deception and consistency over repeated interviews

ABSTRACT

Research indicates that truthful statements typically contain more details than fabricated statements, and that truth tellers are no more consistent than liars over multiple interviews. In this experiment, we examine the impact of (i) multiple interviewers and (ii) reverse order recall on liars’ and truth tellers’ consistency and amount of reported detail over repeated recall attempts. Participants either took part in a mock crime (lying condition) or an innocent event (truth telling condition) which they were subsequently interviewed about in two separate interview phases. Truth tellers provided more details overall, and more reminiscent details than liars. There were no differences between veracity groups for the number of omissions made or repetitions reported. Despite the popular belief that inconsistency is a cue to deception, we found little support for the notion that consistency (or lack of consistency) offers a diagnostic cue to deception. We found little evidence that switching interviewer or recalling in reverse order induced inconsistencies in liars. In fact, due to the number of reminiscent details in truth tellers’ accounts, our findings suggest that accounts provided by liars tend to be slightly more consistent than those provided by truth tellers.

Comparative analysis of gamma-hydroxybutyrate and gamma-hydroxyvalerate using GC/MS and HPLC

This paper describes two analytical techniques used to separate and quantify gamma-hydroxybutyrate (GHB) and gamma-hydroxyvalerate (GHV). The first technique was a N,O-bis(trimethylsilyl)triflouro-acetimide-trimethylchlorosilane derivatization, followed by gas chromatography/mass spectrometry analysis using an HP-5 capillary column at a rate of 1.0 mL/min with a run time of 9.25 min. This technique was found to be sensitive (LOD 1 pg on column) and gave a low average error (5%) in a beverage study. When supplemented by a surrogate spike, the method yielded 97% analyte recovery from beverages. The second technique was high-performance liquid chromatography/UV (HPLC/UV) using a C-18 column with a (20:80% v/v) methanol:dibasic phosphoric buffer (10 mM, pH 3) at a rate of 1.00 mL/min with a run time of 7.5 min. UV detection occurred at 254 nm. This method was found to be less sensitive (LOD 0.05 microg on column) for direct analysis of aqueous samples. To remove interferences seen in the beverage study, a liquid-liquid extraction before HPLC analysis was tested. However, a decreased sensitivity (LOD 100 microg on column) and irreproducible peak profiles resulted.     

Client‐ship and Citizenship in Latin America

This article explores the development of political relationships between people and politicians since around 1820 in Latin America. In particular, it develops the idea of client‐ship as a form of political agency and contrasts it to citizenship, linking both to 'natural' and 'historical' interpretations of inequality. The piece claims that client‐ship has dominated political relations and that its twin tools of charisma and votes‐for‐goods allows it to thrive today in the form of neo‐populism. In contrast, citizenship has been thwarted by the efforts of parties which control political agency by imposing norms of intellectual superiority and hierarchies of disdain. Throughout, I argue that issues of race, gender and class are central to political relationships which are the cultural terrain of power, and conclude that parties must begin to take citizens – and citizenship – seriously if they wish to avert a crisis of democracy.     

Never look back: political thought and the abolition of slavery

The campaigns for the abolition of slavery in the British Empire, spanning over 40 years, represented one of the major political issues of the late Enlightenment, and drew in people of all backgrounds. The very idea of humanity was at stake and this was an issue of broad-based concern. For the abolitionists, the humanity of black slaves was not in doubt, it was the actions of a society who condoned the practice, active or passive, that they saw as inhuman. Against this backdrop, Enlightenment thinkers were working on theories of justice, rights and humanity which would have an enduring influence on politics, society and academic thought for hundreds of years to come. This article addresses this historical context which, it is argued, is vital in reading, interpreting and applying Enlightenment thought in international relations today. The article presents primary and secondary historical evidence to this end and proposes that Spivak's conceptualization of ‘sanctioned ignorance’ offers much for understanding how it can be that European political thought has been so divorced from the context of slavery, from whence it emerged.     

‘When Two Loving Hearts Beat as One’: same‐sex marriage,subjectivity and self‐representation in the Australian case of Marion‐Bill‐Edwards, 1906–1916

This article focuses on the Australian case of Marion‐Bill‐Edwards who lived most of her adult life in male attire. It examines three bursts of publicity Edwards encountered, a 1906 criminal trial, her 1908 autobiography and a 1916 court case in which she was a witness. The case is significant because it makes an important contribution to understandings of the sexual subjectivity of women (especially women of the lower classes) who had same‐sex relationships in the early years of the twentieth century. The article explores changes in Edwards’ self‐representation and subjectivity in this pivotal period in which (research has indicated) new models for modern sexual identities began to emerge.     

A Whole of Government Strategy for Family Violence Reform

The Family Violence Reform strategy in Victoria is one of a number of contemporary government initiatives that have been framed within a whole of government model of policy reform. This article shows how the principles and processes of the whole of government approach were applied to the social problem of family violence. We examine the reasoning behind the adoption of this approach, what it was intended to achieve, the processes and activities that took place and stakeholders’ views about the outcomes and impact of this approach. The choice of a whole of government strategy reflected the need to address philosophical and organisational cultural differences about family violence and responses to it. Key elements were: the demonstrated commitment to reform and leadership provided by ministers, agency heads and senior managers; the involvement of community sector representatives; and the role of the Department of Planning and Community Development (DPCD).     

Mixed effects modelling for glass category estimation from glass refractive indices

520 Glass fragments were taken from 105 glass items. Each item was either a container, a window, or glass from an automobile. Each of these three classes of use are defined as glass categories. Refractive indexes were measured both before, and after a programme of re-annealing. Because the refractive index of each fragment could not in itself be observed before and after re-annealing, a model based approach was used to estimate the change in refractive index for each glass category. It was found that less complex estimation methods would be equivalent to the full model, and were subsequently used. The change in refractive index was then used to calculate a measure of the evidential value for each item belonging to each glass category. The distributions of refractive index change were considered for each glass category, and it was found that, possibly due to small samples, members of the normal family would not adequately model the refractive index changes within two of the use types considered here. Two alternative approaches to modelling the change in refractive index were used, one employed more established kernel density estimates, the other a newer approach called log-concave estimation. Either method when applied to the change in refractive index was found to give good estimates of glass category, however, on all performance metrics kernel density estimates were found to be slightly better than log-concave estimates, although the estimates from log-concave estimation prossessed properties which had some qualitative appeal not encapsulated in the selected measures of performance. These results and implications of these two methods of estimating probability densities for glass refractive indexes are discussed.
