Is There Backlash to Social Pressure? A Large-scale Field Experiment on Voter Mobilization

Using social pressure to mobilize voters has generated impressive increases in turnout (Gerber et al. Am Polit Sci Rev 102:33–48, 2008). However, voters may have negative reactions to social pressure treatments that reduce their effectiveness. Social psychologists have observed this ‘reactance’ to persuasive pressure about other behavior, but it has been overlooked in voter mobilization. Using a large-scale field experiment, we find treatments designed to reduce reactance are just as effective as heavy-handed social pressure treatments in mobilizing voters. The success of gentler social pressure treatments should make the use of social pressure more palatable to voter mobilization organizations.     

Incarceration, education and transition from delinquency

Purpose

Much of what is known regarding the transition away from crime is limited to young adulthood and specific life events and samples of non-serious offenders comprised mainly of white males.

Methods

The current study assesses the potential links between educational achievement, post-release schooling, and re-arrest for a cohort of 4,147 incarcerated youths drawn from 115 Florida juvenile institutions and followed for two years post-release.

Results

Incarcerated youths with higher levels of educational achievement are more likely to return to school after release, and those youths who returned to and attended school regularly were less likely to be rearrested within 12 and 24 months. Moreover, among youths who were rearrested, those youth who attended school regularly following release were arrested for significantly less serious offenses compared to youths who did not attend school or attended less regularly.

Conclusions

The study concludes with discussion of the importance of educational achievement as an important turning point for juvenile offenders as they transition into young adulthood.     

Thermal Imaging as a Lie Detection Tool at Airports

We tested the accuracy of thermal imaging as a lie detection tool in airport screening. Fifty-one passengers in an international airport departure hall told the truth or lied about their forthcoming trip in an interview. Their skin temperature was recorded via a thermal imaging camera. Liars’ skin temperature rose significantly during the interview, whereas truth tellers’ skin temperature remained constant. On the basis of these different patterns, 64% of truth tellers and 69% of liars were classified correctly. The interviewers made veracity judgements independently from the thermal recordings. The interviewers outperformed the thermal recordings and classified 72% of truth tellers and 77% of liars correctly. Accuracy rates based on the combination of thermal imaging scores and interviewers’ judgements were the same as accuracy rates based on interviewers’ judgements alone. Implications of the findings for the suitability of thermal imaging as a lie detection tool in airports are discussed.     

Genetic relationships between blowflies (Calliphoridae) of forensic importance.

Phylogenetic relationships among blowfly (Calliphoridae) species of forensic importance are explored using DNA sequence data from the large sub-unit (lsu, 28S) ribosomal RNA (rRNA) gene, the study includes representatives of a range of calliphorid species commonly encountered in forensic analysis in Britain and Europe. The data presented provide a basis to define molecular markers, including the identification of highly informative intra-sequence regions, which may be of use in the identification of larvae for forensic entomology. Phylogenetic analysis of the sequences also provides new insights into the different evolutionary patterns apparent within the family Calliphoridae which, additionally, can provide a measure of the degree of genetic variation likely to be encountered within taxonomic groups of differing forensic utility.     

An Empirical Test of the Behaviour Analysis Interview

The present experiment is the first empirical test of the Behaviour Analysis Interview (BAI), an interview technique developed by F. E. Inbau, J. E. Reid, J. P. Buckley, & B. C. Jayne (2001) designed to evoke different verbal and non-verbal responses from liars and truth-tellers. Inbau et al. expect liars to be less helpful than truth-tellers in investigations and to exhibit more nervous behaviours. Just the opposite predictions, however, follow from the deception literature, which notes that liars take their credibility less for granted and are therefore more aware of their responses and their impact on others. This suggests that liars' answers should be more helpful than truth-tellers' answers, and liars' non-verbal responses should appear more relaxed than truth-tellers' non-verbal responses. In the present experiment, 40 participants (undergraduate students) lied or told the truth about an event during a BAI interview. The interviews were coded according to Inbau et al.'s guidelines. The results showed that, compared to liars, truth-tellers (a) were more naive and evasive when explaining the purpose of the interview, and (b) were less likely to name someone who they felt certain did not commit the crime. Truth-tellers also exhibited more nervous behaviours. The results were consistent with the predictions of the deception literature, and directly opposed to the predictions of BAI.     

Duress, International Criminal Law and Literature

This paper uses parallels between Sophocles’ Theban Playsand the House of Lords decision in Dudley and Stephens, to questionthe decision in the Erdemovi case before the International CriminalTribunal for the former Yugoslavia. One should distinguish betweencausal, moral and criminal responsibility. If a man who commitsa crime, not by the action of his free will, is to be foundguilty, we are essentially equating causal responsibility withcriminal guilt. This logic clearly does not correspond withthat of the rest of international criminal law. The storiesof Erdemovi, Oedipus, Dudley and Stephens are tragedies. Eachof the victims/perpetrators felt an overwhelming sense of remorse.Whether they should be considered morally guilty of murder isa matter of individual conscience. The International CriminalTribunal for the Former Yugoslavia majority erred in using anabsolute moral position in Erdemovi. The majority's moral condemnationof the killing of innocents was confused with the question ofwhether Erdemovi should have been criminally punished. The contentof the majority opinion is largely of an irreproachably moralisticnature, though shrouded and mystified by the discussion of precedent.More generally, the decision to try Erdemovi at the InternationalCriminal Tribunal for the Former Yugoslavia was itself self-defeating.Erdemovi should never have stood trial at The Hague. The internationalcommunity should not aid in self-flagellation. While his actionscannot be approved of, they should not be punished internationally.He could have been helped, supported and reintegrated with fargreater benefit to all.         ‘Heroesare hard to find in an atmosphere of total terror.’¹
