Essentialism and the criminal legal system.

Objective: Existing literature has yet to conceptualize and consolidate research on psychological essentialism and its relation to the criminal legal system, particularly in terms of explaining how individuals with justice involvement have been and could be differentially impacted across contexts. This article explores essentialism in the criminal legal system, including its potential consequences for inequity.

Method: We review research on essentialism as a psychological construct, its common applications to different social categorizations, and its trickle-down effects within the criminal legal system.

Portrayals of gun violence victimization and public support for firearm policies: an experimental analysis.

Objectives: This study examines how characteristics of victims and types of incidents described in a media account of gun violence affect public support for three categories of policies that regulate firearms.

Methods: A randomized experiment with a sample of US public ( = 3410).

Results: Victim race, particularly if the victim was Black, was a strong predictor of less public support for all tested categories of firearm regulation.

Bio-behavioral scientific evidence alters judges' sentencing decision-making: A quantitative analysis.

The present study surveyed judges to examine how they consider and apply scientific information during sentencing determinations. Judges in criminal courts are increasingly asked to assess and make decisions based on evidence surrounding psychiatric disorders, with unclear results on sentencing outcomes. We qualitatively interviewed 34 judges who have presided over criminal cases in 16 different states and also administered vignette surveys during the interviews.

The effects of a defendant's childhood physical abuse on lay support for sentencing: The moderating role of essentialism.

Research suggests that a defendant's history of experiencing childhood abuse, and its effects on their life and later decision-making, may impact public support for a defendant's sentencing, particularly mitigation. However, no existing research has examined how and why sentencing support may vary based on the time period when the abuse occurs during a defendant's childhood. This experiment, using a sample of the U.

Identification and support of autistic individuals within the UK Criminal Justice System: a practical approach based upon professional consensus with input from lived experience.

Background: Autism spectrum disorder (hereafter referred to as autism) is characterised by difficulties with (i) social communication, social interaction, and (ii) restricted and repetitive interests and behaviours. Estimates of autism prevalence within the criminal justice system (CJS) vary considerably, but there is evidence to suggest that the condition can be missed or misidentified within this population. Autism has implications for an individual's journey through the CJS, from police questioning and engagement in court proceedings through to risk assessment, formulation, therapeutic approaches, engagement with support services, and long-term social and legal outcomes.

Acquired Pedophilia: international Delphi-method-based consensus guidelines.

Idiopathic and acquired pedophilia are two different disorders with two different etiologies. However, the differential diagnosis is still very difficult, as the behavioral indicators used to discriminate the two forms of pedophilia are underexplored, and clinicians are still devoid of clear guidelines describing the clinical and neuroscientific investigations suggested to help them with this difficult task. Furthermore, the consequences of misdiagnosis are not known, and a consensus regarding the legal consequences for the two kinds of offenders is still lacking.

A jury of scientists: Formal education in biobehavioral sciences reduces the odds of punitive criminal sentencing.

This study examines how formal education in biological and behavioral sciences may impact punishment intuitions (views on criminal sentencing, free will, responsibility, and dangerousness) in cases involving neurobiological evidence. In a survey experiment, we compared intuitions between biobehavioral science and non-science university graduates by presenting them with a baseline case without a neurobiological explanation for offending followed by one of two cases with a neurobiological explanation (described as either innate or acquired biological influences to offending). An ordinal logistic regression indicated that both science and non-science graduates selected significantly more severe punishments for the baseline case as compared to when an innate neurobiological explanation for offending was provided.

Losing the lottery of life: Examining intuitions of desert toward the socially and genetically "unlucky" in criminal punishment contexts.

This research presents three experiments that examine how natural "luck" (social and genetic luck) may affect lay intuitions toward desert-based criminal punishment. Study 1 examined if intuitions surrounding desert-based rewards in relation to good qualities/advantages ascribed to natural luck would extend to desert-based punishments in relation to bad qualities/disadvantages ascribed to natural luck. Study 2 examined how both social and genetic luck affect support for desert-based punishment across different criminal offenses and tests the relevance of immanent justice reasoning to such support.

A Dual-Process Approach to Moral Panic and Public Support for Sex Offender Management Policies.

The current study explores if and how dual-process thinking styles (System I/experiential and System II/rational processing) predict and explain the degree to which members of the public express moral panic toward and support for existing sex offender management policies (registration, notification, residence restrictions), regardless of their efficacy or effects on recidivism rates, for different types of individuals who commit sex offenses (sex offender, juvenile sex offender, cybersex offender, female sex offender, rapist, child molester). Online experimental methods were used with a lay sample ( = 324). Results show that the extent to which participants exhibited a reliance on System I processing significantly predicted their feelings of moral panic (concern, hostility, and volatility) toward individuals classified as child molesters.

A tale of "second chances": an experimental examination of popular support for early release mechanisms that reconsider long-term prison sentences.

Objectives: This study examines US popular support for mechanisms that provide early release and "second chances" for individuals serving long-term prison sentences.

Methods: An experiment using a national sample of US adults (=836).

Results: Data showed moderate, consistent levels of general support for using a range of commonly available "second chance" mechanisms that also extended to offenders convicted of both violent and non-violent offenses.

The importance of forensic evidence for decisions on criminal guilt.

Recent studies have found that the general public perceives forensic evidence to be relatively inaccurate and to involve high levels of human judgement. This study examines how important the general public finds forensic evidence by comparing decisions on guilt and punishment in criminal cases that involve forensic versus eyewitness testimony evidence and examining whether a CSI effect exists. Specifically, this experimental survey study utilized a 2 (crime type: murder or rape) × 4 (evidence type: DNA, fingerprint, victim eyewitness testimony, or bystander eyewitness testimony) - 1 (no victim testimony for murder scenario) design, yielding seven vignettes scenarios to which participants were randomly assigned.

The potential influence of criminological rationales in considering childhood abuse as mitigating to sentencing.

Background: U.S. courts currently show no coherent approach with regard to how evidence of childhood abuse is considered in sentencing.

Cognitive and Affective Processing of Risk Information: A Survey Experiment on Risk-Based Decision-Making Related to Crime and Public Safety.

The current study, using a multi-factorial survey experiment with a sample of the general public ( = 800), investigates if and how types of risk information on crime and public safety, such as maps, graphs, or tables, commonly used and communicated by law enforcement elicit dual-process (affective and cognitive) risk information processing in risk-based decision-making, and if such processing or decision-making differs depending on the risk level, context, or the type or format of risk information communicated. Participants responded to a vignette in which they were asked to choose a ride-share pick-up point within a certain geographic area with varying risk levels of being involved in a pedestrian-automobile crash. Results showed that risk information related to crime and public safety elicits dual-process risk information processing, and that both affective and cognitive processing significantly predicted risk-based decision-making, regardless of the risk level or type of risk information examined.

The effects of essentialist thinking toward biosocial risk factors for criminality and types of offending on lay punishment support.

This research uses experimental methods to gauge how different facets of essentialist thinking toward (1) types of offending and (2) biosocial risk factors for criminality predict lay punishment support. A randomized between-subjects experiment using contrastive vignettes was conducted with members of the general public (N = 897). Overall, as hypothesized, aspects of essentialist thinking, particularly informativeness, continuity, immutability, and discreteness, toward both biosocial risk factors and types of offending behavior generally predicted more severe punishments surrounding retribution, incapacitation, and deterrence.

The Brain of Dexter Morgan: the Science of Psychopathy in Showtimes Season 8 of .

This article identifies and discusses on the ways in which biological influences to psychopathy are thematically portrayed in the eighth season of to describe Dexter's psychopathy, particularly focusing on fatalism and the inevitability of succumbing to one's "biological self." This paper, utilizing traditional content analysis, focuses on seven qualitative themes surrounding "biological fatalism" and psychopathy in this final season of As lay theories of psychopathy are thought to originate from the media's conceptualization of the disorder, such thematic portrayals serve to potential affect lay understandings of psychopathy and correspondingly, how the disorder is treated and perceived in the criminal justice process as a modern psychopathy-related "CSI Effect." The conclusion focuses on the messages that this final season of Dexter sends to the lay public about the biological influences to psychopathy and how this may create implications for the criminal justice system.

How information about perpetrators' nature and nurture influences assessments of their character, mental states, and deserved punishment.

Evidence of perpetrators' biological or situational circumstances has been increasingly brought to bear in courtrooms. Yet, research findings are mixed as to whether this information influences folk evaluations of perpetrators' dispositions, and subsequently, evaluations of their deserved punishments. Previous research has not clearly dissociated the effects of information about perpetrators' genetic endowment versus their environmental circumstances.

The psychopathic "label" and effects on punishment outcomes: A meta-analysis.

The current study, using a meta-analytic approach and moderation analysis, examines 22 studies reporting how psychopathic "labeling" influences perceptions on 3 punishment outcomes (dangerousness, treatment amenability, and legal sentence/sanction) for 2 types of experimental studies utilizing vignettes: (a) studies in which a defendant with a psychopathic "label" is compared to a defendant with no mental health diagnosis (psychopathic label vs. no label) and (b) studies in which a defendant with a psychopathic "label" is compared to a defendant with a different psychiatric diagnosis (psychopathic label vs. other psychiatric label).

Educator of the Court: The Role of the Expert Witness in Cases Involving Autism Spectrum Disorder.

The role of the expert witness in legal contexts is to educate fact finders of the court who may have no background in the expert's area. This role can be especially difficult for those who assist in cases involving individuals with Autism Spectrum Disorder (ASD). As expert assistance on ASD is crucial to ensuring just outcomes for individuals diagnosed with ASD, knowledge on how expert witnesses perceive and approach their roles, and what factors may influence these perceptions, is essential.

Public attitudes toward legally coerced biological treatments of criminals.

How does the public view the offer of a biological treatment in lieu of prison for criminal offenders? Using the contrastive vignette technique, we explored this issue, using mixed-methods analysis to measure concerns regarding changing the criminal's personality, the coercive nature of the offer, and the safety of the proposed treatment. Overall, we found that of the three variables, the safety of the pill had the strongest effect on public acceptance of a biological intervention. Indeed, it was notable that the public was relatively sanguine about coercive offers of biological agents, as well as changing the personality of criminals.

Judges' views on evidence of genetic contributions to mental disorders in court.

This preliminary analysis assesses how judges view the use of behavioral genetics evidence on genetic influences to mental disorders in court. Twenty-one semi-structured interviews, analyzed using constant comparative analysis, were conducted with California trial court judges. Most judges reported the beneficial effects of this evidence being presented in court, particularly as a mitigating factor for sentencing.

Attention, reward, and inhibition: symptomatic features of ADHD and issues for offenders in the criminal justice system.

Although the relationship between criminal activity and ADHD has been heavily studied, this paper reviews a largely neglected area of academic discourse: how symptoms of ADHD that often contribute to offending behavior may also potentially create further problems for offenders with ADHD after they come into contact with the criminal justice system and pilot their way through the legal process. The main symptoms of ADHD that are primarily connected to criminal offending are examined and contextualized with respect to diagnosed offenders' experiences with the justice system. Symptoms of ADHD, specifically reward deficiency, behavioral inhibition, and attention deficits, may affect whether individuals will be successful in their experiences in court, with probation, and during incarceration.

Brief Report: Judicial Attitudes Regarding the Sentencing of Offenders with High Functioning Autism.

This brief report presents preliminary data on the attitudes of judges on the sentencing of offenders with High Functioning Autism (HFA). Semi-structured telephone interviews were conducted with twenty-one California Superior Court Judges. Interviews were qualitatively coded and constant comparative analysis was utilized.
