Artificial fairness? Trust in algorithmic police decision-making.

Objectives: Test whether (1) people view a policing decision made by an algorithm as more or less trustworthy than when an officer makes the same decision; (2) people who are presented with a specific instance of algorithmic policing have greater or lesser support for the general use of algorithmic policing in general; and (3) people use trust as a heuristic through which to make sense of an unfamiliar technology like algorithmic policing. Methods: An online experiment tested whether different decision-making methods, outcomes and scenario types affect judgements about the appropriateness and fairness of decision-making and the general acceptability of police use of this particular technology. Results: People see a decision as less fair and less appropriate when an algorithm decides, compared to when an officer decides. Yet, perceptions of fairness and appropriateness were strong predictors of support for police use of algorithms, and being exposed to a successful use of an algorithm was linked, via trust in the decision made, to greater support for police use of algorithms. Conclusions: Making decisions solely based on algorithms might damage trust, and the more police rely solely on algorithmic decision-making, the less trusting people may be in decisions. However, mere exposure to the successful use of algorithms seems to enhance the general acceptability of this technology.

Fear Appeals in Anti-Knife Carrying Campaigns: Successful or Counter-Productive?

In the UK, knife crime continues to be a persistent and worrying concern. Media campaigns are often used by police and anti-knife crime organisations in an attempt to discourage young people from picking up a weapon. Many focus on the potentially devastating consequences associated with carrying a weapon, with the aim of provoking fear and thus a deterrent effect. In this paper, we present the findings from two experimental studies exploring the effects of exposure to fear-based knife crime media campaigns on young people's intentions to engage in knife-carrying behaviour. Utilising a terror management theory perspective, in both studies we found that exposure to knife-related campaign imagery increased mortality salience, but there was no effect of campaign condition on willingness to carry a knife or on perceived benefits of knife-carrying. Although knife-related self-esteem/cultural worldviews predicted attitudes towards knife-carrying, such views did not moderate the effect of exposure to knife-related campaign imagery, and there was no effect of priming participants' to consider the value of behaving responsibly. Implications and suggestions for future research are discussed.

Supporting child witnesses during identification lineups: Exploring the effectiveness of registered intermediaries.

Performance at identification lineup was assessed in eighty-five 6- to 11-year-old typically developing children. Children viewed a live staged event involving 2 male actors, and were asked to identify the perpetrators from 2 separate lineups (one perpetrator-present lineup and one perpetrator-absent lineup). Half the children took part in lineups adapted by a registered intermediary (an impartial, trained professional who facilitates understanding and communication between vulnerable witnesses and members of the justice system), and half took part in "best-practice" lineups, according to the current guidance for eyewitness identification in England and Wales. Children receiving assistance from a registered intermediary (relative to children who received best-practice lineups) were more accurate in their identifications for perpetrator-present lineups, and there was some evidence that they were also more accurate for perpetrator-absent lineups. This provides the first empirical evidence for the effectiveness of registered intermediary support during identification lineups.

Verbal, Visual, and Intermediary Support for Child Witnesses with Autism During Investigative Interviews.

Three promising investigative interview interventions were assessed in 270 children (age 6-11 years): 71 with autism spectrum disorder (ASD) and 199 who were typically developing (TD). Children received 'Verbal Labels', 'Sketch Reinstatement of Context' or 'Registered Intermediary' interviews designed to improve interview performance without decreasing accuracy. Children with ASD showed no increases in the number of correct details recalled for any of the three interview types (compared to a Best-Practice police interview), whereas TD children showed significant improvements in the Registered Intermediary and Verbal Labels interviews. Findings suggested that children with ASD can perform as well as TD children in certain types of investigative interviews, but some expected benefits (e.g., of Registered Intermediaries) were not apparent in this study.

The relation between trust beliefs and loneliness during early childhood, middle childhood, and adulthood.

Four studies examined the relation between trust and loneliness. Studies 1, 2, and 3 showed that trust beliefs negatively predicted changes in loneliness during early childhood (5-7 years), middle childhood (9-11 years), and young adulthood (18-21 years). Structural equation modeling yielded support for the hypothesis that the relation between trust beliefs and loneliness was mediated, in part, by social disengagement, which varied by age and gender. Study 4 showed that when young adults were primed for distrust rather than for trust cognitions, they showed greater withdrawal (loneliness) affect, lower willingness to disclose, and less perceived success in achieving rapport. The findings yielded support for the hypotheses that (a) low trust beliefs promote loneliness from childhood to adulthood and (b) social disengagement and cognitive schema mechanisms account for the relation.
