Failing to tell friend from foe: A comment on Wijn et al. (2017)

Behavioural observation programmes are becoming increasingly popular at transportation hubs, sporting events, and other large crowd gatherings. Premise of these programmes is that malicious intention can be accurately deduced from observable behaviour. In a recent article published in this journal, Wijn et al. (2017, Legal and Criminological Psychology, 22, 378–399.) conclude that environmental cues improve the correct detection of participants with malicious intent. This conclusion can and will be interpreted as support for behavioural observation programmes. In this comment, we argue that Wijn and colleagues draw a fundamentally wrong conclusion from their data. What their data show is that malicious intentions could not be detected in any of the conditions. Their findings can therefore not be conceptualized as evidence for behavioural observation programmes. Rather, they add to the growing critique voiced towards such programmes.     

Some reflections on Smith and Crosby's “affirmative action: Setting the record straight”

Conclusion Through it may initially seem simple and straightforward, affirmative action is an extremely complex concept linked to a variety of programs that attempt to address central institutional sources of injustice. Smith and Crosby (1994) have identified several important and contentious issues that have emerged in the debate over affirmative action programs and their effects over the past 30 years. They have also contributed to the continuing need to refine our understanding of injustice and the individual and institutional obstacles that often frustrate attempts to confront injustice. By reflecting critically on their contribution, I have tried to add to that understanding. Several of the ideas in this paper were originally prepared for and presented at the Stuckenberg Conference on Social Policies and Social-Psychological Research on Human Values, held at Washington University, St. Louis, in April 1992.     

A Validation Study of the Langley et al. (2017) Decision Tree Model for Sex Estimation

Langley et al. (2017) developed a sex estimation decision tree utilizing two traditional cranial traits (glabella and mastoid) and a new trait: zygomatic extension. This study aimed to test the reliability of their zygomatic extension scoring method and validate their sex estimation method. Ordinal score data were collected from 281 male and female U.S. White and Black individuals. The five traditional cranial traits were collected from physical specimens, while zygomatic extension was scored from 3D cranial models. Intra‐ and interobserver analyses carried out on a subsample of 30 individuals indicate good agreement between zygomatic scores. The decision tree correctly sexed 71.5% of the sample, but a strong sex bias (94.2% correct for females, 49.3% correct for males) severely limits the utility of this method. The Walker (2008) and Stevenson et al. (2009) methods produced higher accuracy rates (80.8% and 82.6%, respectively), although these methods also produced sex and ancestry biases.

Self-control behind bars: A validation study of the Grasmick et al. scale

Much empirical support of self-control theory is based on the 24-item scale conceptualized by Grasmick and his colleagues. This study examined the dimensionality of the scale. Exploratory factor analysis, confirmatory factor analyses, and a structural equation model (SEM) produced results that are discordant with much prior research. The Grasmick et al. scale was not unidimensional, more complex theoretical iterations failed to meet most goodness-of-fit statistics, and considerable refinement via modification indices was needed before a measurement model that fit the data could be found. Further refinement is required to justify it as the quintessential measure of self-control.

Complex mixtures: A critical examination of a paper by Homer et al.

DNA evidence in criminal cases may be challenging to interpret if several individuals have contributed to a DNA-mixture. The genetic markers conventionally used for forensic applications may be insufficient to resolve cases where there is a small fraction of DNA (say less than 10%) from some contributors or where there are several (say more than 4) contributors. Recently methods have been proposed that claim to substantially improve on existing approaches [1]. The basic idea is to use high-density single nucleotide polymorphism (SNP) genotyping arrays including as many as 500,000 markers or more and explicitly exploit raw allele intensity measures. It is claimed that trace fractions of less than 0.1% can be reliably detected in mixtures with a large number of contributors. Specific forensic issues pertaining to the amount and quality of DNA are not discussed in the paper and will not be addressed here. Rather our paper critically examines the statistical methods and the validity of the conclusions drawn in Homer et al. (2008) [1].We provide a mathematical argument showing that the suggested statistical approach will give misleading results for important cases. For instance, for a two person mixture an individual contributing less than 33% is expected to be declared a non-contributor. The quoted threshold 33% applies when all relative allele frequencies are 0.5. Simulations confirmed the mathematical findings and also provide results for more complex cases. We specified several scenarios for the number of contributors, the mixing proportions and allele frequencies and simulated as many as 500,000 SNPs.A controlled, blinded experiment was performed using the Illumina GoldenGate^® 360 SNP test panel. Twenty-five mixtures were created from 2 to 5 contributors with proportions ranging from 0.01 to 0.99. The findings were consistent with the mathematical result and the simulations.We conclude that it is not possible to reliably infer the presence of minor contributors to mixtures following the approach suggested in Homer et al. (2008) [1]. The basic problem is that the method fails to account for mixing proportions.     

Increasing pressure does not benefit lie detection: a reply to Ten Brinke et al. (2015)

When passively attending to suspects, observers are poor at distinguishing lies from truths. Deception research has therefore shifted to examining interview styles aimed at eliciting and enhancing deception cues. Based upon a literature review and three empirical studies, ten Brinke, L., Khambatta, P., and Carney, D. R. [2015. Physically scarce (vs. enriched) environments decrease the ability to successfully tell lies. Journal of Experimental Psychology: General, 144, 982–992. doi:10.1037/xge0000103] recommend increasing pressure on interviewees as it would increase lie detection accuracy. In this comment, we argue that these authors (1) misinterpret the literature when concluding that lie detection benefits from increasing pressure on interviewees, and (2) their data do not show that lie detection is more accurate when pressure is increased. In absence of such data, we recommend that increasing pressure on interviewees should be avoided: it hampers the elicitation of valuable information and can lead to false confessions.     

(Re-)Setting the Scholarly Agenda on Transjudicial Communication

We consider the contributions made by Robert H. Bork's Coercing Virtue (2003) and Anne-Marie Slaughter's A New World Order (2004) to the ongoing debate over the citation of foreign law in United States courts. While empirically minded sociolegal scholars might be tempted to dismiss these books as mere op-eds, that would be a mistake. Taken with the spate of other recent work, they supply the makings of an agenda for rigorous research devoted to understanding the exchange of law among nations.
