52% Yes, a signiicant crisis 3% No, there is no crisis 7% Don't know 38% Yes, a slight crisis 38% Yes, a slight crisis 1,576 RESEARCHERS SURVEYED M ore than 70% of researchers have tried and failed to reproduce another scientist's experiments, and more than half have failed to reproduce their own experiments. Those are some of the telling figures that emerged from Nature's survey of 1,576 researchers who took a brief online questionnaire on reproducibility in research. The data reveal sometimes-contradictory attitudes towards reproduc-ibility. Although 52% of those surveyed agree that there is a significant 'crisis' of reproducibility, less than 31% think that failure to reproduce published results means that the result is probably wrong, and most say that they still trust the published literature. Data on how much of the scientific literature is reproducible are rare and generally bleak. The best-known analyses, from psychology 1 and cancer biology 2 , found rates of around 40% and 10%, respectively. Our survey respondents were more optimistic: 73% said that they think that at least half of the papers in their field can be trusted, with physicists and chemists generally showing the most confidence. The results capture a confusing snapshot of attitudes around these issues, says Arturo Casadevall, a microbiologist at the Johns Hopkins Bloomberg School of Public Health in Baltimore, Maryland. "At the current time there is no consensus on what reproducibility is or should be. " But just recognizing that is a step forward, he says. "The next step may be identifying what is the problem and to get a consensus. "

Despite empirical progress in documenting and classifying various interrogation techniques, very little is known about how police are trained in interrogation methods, how frequently they use various techniques, and whether they employ techniques differentially with adult versus juvenile suspects. This study reports the nature and extent of formal (e.g., Reid Technique, PEACE, HUMINT) and informal interrogation training as well as self-reported technique usage in a diverse national sample (N = 340) of experienced American police officers. Officers were trained in a variety of different techniques ranging from comparatively benign pre-interrogation strategies (e.g., building rapport, observing body language or speech patterns) to more psychologically coercive techniques (e.g., blaming the victim, discouraging denials). Over half the sample reported being trained to use psychologically coercive techniques with both adults and juveniles. The majority (91%) receive informal, "on the job" interrogation training. Technique usage patterns indicate a spectrum of psychological intensity where information-gathering approaches were used most frequently and high-pressure tactics less frequently. Reid-trained officers (56%) were significantly more likely than officers without Reid training to use pre-interrogation and manipulation techniques. Across all analyses and techniques, usage patterns were identical for adult and juvenile suspects, suggesting that police interrogate youth in the same manner as adults. Overall, results suggest that training in specific interrogation methods is strongly associated with usage. Findings underscore the need for more law enforcement interrogation training in general, especially with juvenile suspects, and highlight the value of training as an avenue for reducing interrogation-induced miscarriages of justice.

Although empirical attention to police interrogation has gained traction in recent years, comparatively few studies have examined interrogation of juvenile suspects, and virtually none have examined actual interrogations. Despite a growing literature on youths' interrogation-related capacities, we still know very little about what actually transpires when police question youth. The present study examines electronically recorded police interviews with juveniles to describe the characteristics, processes, and outcomes that occur in actual juvenile interrogations, including interview duration, individuals present, and confessions. Fifty-seven electronic recordings from 17 police departments were analyzed using observational research software. The median juvenile interrogation lasted 46 min, though the range was extensive (6 min to nearly 5 hr). Youth frequently submitted to questioning without a parent or advocate present, and disruptions to the interview process were common. Interrogation outcomes varied and included full confessions, partially incriminating admissions, and denials of guilt. Results from this study provide context for interrogation research using other methods and suggest that youth may frequently consent to interrogation in the absence of important legal protections.

Public policy in the area of youth crime has periodically shifted back and forth between punishment and child saving. Generally, scholars believe that public opinion and youth justice policies are linked. It is also believed that crime salience—fear and perceived risk of victimization—is linked to public opinion about youth sanctions. To test these widely held beliefs, this study examines public opinion about youth justice policies by exploring the impact of crime salience on public support for child saving versus youth punishment. This study expands on prior literature by also considering the public’s willingness to pay (WTP) for the youth justice policies they prefer. Results indicate that fear increases punitiveness, WTP for youth justice policies generally, and, more specifically, the WTP for youth punishment. However, fear does not affect the public’s WTP for child saving. Limitations and suggestions for future research are discussed.

Police interrogation of criminal suspects is a core function of the American justice system that involves numerous cognitive, social, and other psychological processes. While a robust psycholegal literature on police interrogation has emerged, the subset of that literature focusing on adolescent suspects is less cohesive, despite substantial and well-known developmental differences between adult and juvenile suspects. With a few notable exceptions, the current juvenile interrogation literature has not systematically leveraged the many lessons of normative adolescent development that have emerged from basic scientific research. Developmental psychology has much to offer the study of juvenile interrogation, and as police–youth interactions increasingly capture the public’s attention and raise important questions about how police handle juveniles, now is the time to adopt a more explicitly developmental approach. This article highlights key features of adolescent psychosocial, neurobiological, and social development that are directly relevant to the police interrogation context. It argues that an explicit recognition of developmental principles is vital to juvenile suspects’ due process rights and to the future of juvenile interrogation research. The article outlines specific directions for future research on juvenile interrogation, including recommendations for interdisciplinary collaborations, laboratory research, and field studies. It then discusses implications of several key recommendations for interrogation policy and practice as they apply specifically to juvenile suspects.

Few studies have examined police interrogation strategies from suspects' perspectives, yet assessing suspects' views about interviewer approaches could provide important insights regarding confession decision making. The current study is the first American survey to assess a diverse sample of adult jail inmates' views on police interrogation tactics and approaches. The study explored US jail inmates' (N = 418) perspectives about how police should conduct interrogations. Potential dimensionality among 26 survey items pertaining to police tactics was examined using exploratory factor analysis. Group differences according to demographic and criminological variables were also explored. Four factors emerged, conceptualized as Dominance/Control, Humanity/Integrity, Sympathy/Perspective-Taking, and Rapport. Respondents most strongly endorsed Humanity/Integrity and Rapport strategies and were unsupportive of approaches involving Dominance/Control. Gender differences emerged for Dominance/ Control and Humanity/Integrity, and Black respondents were more likely to value strategies related to Sympathy/Perspective-Taking. Suspects endorsed interrogation strategies characterized by respect, dignity, voice, and a commitment to the truth; they reported aversions to the false evidence ploy and approaches involving aggression. Overall, results from this incarcerated sample suggest that interviewees may be more responsive to rapport-building, non-adversarial strategies.
