Is There a Relationship between Psychotic Disorders and the Radicalization Process? A Systematic Review.

Background and Objectives: Radicalization, a complex and multifaceted phenomenon, has been a subject of increasing concern in recent years, particularly due to its potential connection to acts of mass violence and terrorism. This systematic review examines the intricate link between radicalization and psychotic disorders, utilizing various sources such as observational studies, case reports, and series. It aims to highlight the prevalence of schizophrenia spectrum and other psychotic disorders among radicalized individuals and to define the role of mental health professionals in dealing with this issue, contributing to the development of prevention and treatment strategies. Materials and Methods: The methodology involved an extensive literature search across PubMed, Scopus, and APA PsycINFO up to 1 February 2024, adhering to PRISMA guidelines. The study focused on radicalization and psychotic disorders as defined by DSM-5 criteria, excluding other mental disorders. A population sample of 41 radicalized individuals diagnosed with psychotic disorders was selected, among which schizophrenia was identified as the predominant condition. Results: It was observed that 24% of these individuals passed away soon after committing their crimes, leading the researchers to rely on retrospective data for their diagnoses. The use of diverse assessment tools for psychiatric diagnosis and the lack of a standardized method for diagnosing or assessing involvement in the radicalization process were also noted. Despite limitations like reliance on observational studies and case reports, which result in low evidence quality and varied methodologies, our work provides a valuable contribution to clarifying the relationship between radicalization and psychotic disorders. However, further clinical studies are needed to delve deeper into these aspects. Conclusions: In conclusion, our review points out that individuals with psychotic disorders do not have a higher crime rate than the general population and warns against associating crimes with mental illness due to the stigma it creates. The lack of uniform psychiatric diagnostic tools and radicalization assessment highlights the need for more standardized risk assessment tools and validated scales in psychiatric diagnosis to better understand the relationship between radicalization and psychotic disorders and to develop integrated protocols.

Disentangling Support for Violent and Non-violent Radicalization among Adolescents: A Latent Profile Analysis.

Although support for violent and non-violent radicalization can co-occur, only a few adolescents who support non-violent radicalization also support or engage in violent acts. Yet, little is known about what factors are associated with adolescents' paths towards or away from violent and/or non-violent radicalization. Within a socio-ecological and positive youth development framework, this study investigates profiles of support for violent and non-violent radicalization among adolescents attending high schools in Quebec (Canada) and whether such profiles are differently associated with experiences of social adversity, school-, family- and peer-related factors and psychological distress. Adolescents (N = 1911; Mage = 15.7; SDage = 0.98; 48.7% girls) completed an online survey during school hours. A Latent Profile Analysis on scores of support for violent and non-violent radicalization was conducted. A multinomial logistic regression was used to explore the associations between profiles and variables of interest. We identified six profiles of adolescents. The heterogeneity of profiles suggested multiple and complex combinations of support for violent and non-violent radicalization as well as their co-existence in some but not all profiles. Adolescents who reported less discrimination, more positive school experiences and more family support were less likely to belong to profiles that supported violence. Primary prevention efforts in the field of support for violent radicalization must adopt a socio-ecological and social justice approach and consider the diversity of adolescents' profiles, attitudes and experiences.

Digital media use, depressive symptoms and support for violent radicalization among young Canadians: a latent profile analysis.

BACKGROUND: Despite the prominent role that digital media play in the lives and mental health of young people as well as in violent radicalization (VR) processes, empirical research aimed to investigate the association between Internet use, depressive symptoms and support for VR among young people is scant. We adopt a person-centered approach to investigate patterns of digital media use and their association with depressive symptoms and support for VR. METHODS: A sample of 2,324 Canadian young people (Mage = 30.10; SDage = 5.44 ; 59% women) responded to an online questionnaire. We used latent profile analysis to identify patterns of digital media use and linear regression to estimate the associations between class membership, depressive symptoms and support for VR. RESULTS: We identified four classes of individuals with regards to digital media use, named Average Internet Use/Institutional trust, Average internet use/Undifferentiated Trust, Limited Internet Use/Low Trust and Online Relational and Political Engagement/Social Media Trust. Linear regression indicated that individuals in the Online Relational and Political Engagement/Social Media Trust and Average Internet Use/Institutional trust profiles reported the highest and lowest scores of both depression and support for VR, respectively. CONCLUSIONS: It is essential to tailor prevention and intervention efforts to mitigate risks of VR to the specific needs and experiences of different groups in society, within a socio-ecological perspective. Prevention should consider both strengths and risks of digital media use and simulteaneously target both online and offline experiences and networks, with a focus on the sociopolitical and relational/emotional components of Internet use.

From Envy to Radicalization.

Models of radicalization have typically placed grievances at the heart of radicalization. In contrast, we argue that viewing the radicalizing agent as decidedly proactive, and less reactive, better accounts for the available data. At the core of our radicalization model is the functional structure of envy. The operative properties of the emotion align with essential and conspicuous features of the radicalization process: a motivation to monitor social differentials, an identification of sources of postulated welfare costs, an impulse to eliminate or depower purported competitors, an attempt to diffuse responsibility for one's aggressive actions, and the rejoicing at the envied agent's misfortune. Two of those operative properties are particularly important for our understanding of radicalization. Envy motivates the neutralization of competitors when responsibility for welfare costs is not objectively attributable to others' wrongdoing toward the party who feels injured. The "process of typification" serves as a means to diffuse responsibility. It extends the reach of individual concerns by downplaying the particulars of the personal situation motivating the envious agent while evoking universally shared interaction templates (e.g., humiliation, injustice) to appeal to a broader audience.

"Consumed by creed": Obsessive-compulsive symptoms underpin ideological obsession and support for political violence.

Radicalization is a process by which individuals are introduced to an ideological belief system that encourages political, religious, or social change through the use of violence. Here we formulate an obsessive-compulsive disorder (OCD) model of radicalization that links obsessive passion (OP; one of the best predictors of radical intentions) to a larger body of clinical research. The model's central tenet is that individual differences in OCD symptom severity could shape radical intentions via their influence on OP. Across four ideological samples in the United States (Environmental activists, Republicans, Democrats, and Muslims, Ntotal = 1114), we found direct effects between OCD symptom severity and radical intentions, as well as indirect effects of OCD on radical intentions via OP. Even after controlling for potential individual difference and clinical confounds (e.g., adverse childhood experiences, loss of significance, and substance abuse), these relationships remained robust, implying that OCD plays a significant role in the formation of violent ideological intentions and opening new avenues for the treatment and prevention of violent extremism. We discuss the implications of conceptualizing radicalization as an OCD-like disorder with compulsive violent tendencies and ideology-related concerns.

Pathway to terrorist behaviors: The role of childhood experiences, personality traits, and ideological motivations in a sample of Iraqi prisoners.

Radicalization to terrorism is a multifaceted process with no single theory or approach to explain it. Although research has focused on understanding the process, there is still a dearth of studies that examine an empirically driven pathway to terrorism behavior. This study examines a cross-sectional sample of incarcerated men convicted of terrorism in Iraq (N = 160). A questionnaire-guided interview included adverse childhood experiences (ACEs), conduct disorder (CD), antisocial personality disorder (ASPD), religious and political ideology, views about causes of terrorism, and the severity of terrorist acts. Path analysis was employed to examine the relationships between these factors and to identify the model with the best fit. After adjusting for age, employment, and location, results indicated that ACEs positively impacted CD, ASPD, religious guidance, and terrorism attitudes. ASPD positively affected political commitment and terrorism attitudes, but inversely affected current religious commitment. Political commitment inversely influenced terrorism attitudes. Religious commitment positively influenced the prioritization of religion in life, which subsequently impacted terrorism attitudes and behavior severity. Additionally, attitudes toward terrorism directly affected the severity of terrorism behavior. All paths in the final model were statistically significant at p < 0.05. Although these findings may be limited in generalizability due to the unique sample, results support the complex and interdependent nature of childhood and adult experiences on the development of both terrorism attitudes and the severity of terrorism behavior.

The Behavioral Inhibition System and Engagement With, and Influence By, COVID-19 and Election-Based Misinformation.

The negative impact of misinformation on public discourse and public safety is increasingly a focus of attention. From the COVID-19 pandemic to national elections, exposure to misinformation has been linked to conflicting perceptions of social, economic, and political issues, which has been found to lead to polarization, radicalization, and acts of violence at the individual and group level. While a large body of research has emerged examining the development and spread of misinformation, little has been done to examine the human processes of being exposed to, and influenced by, misinformation material online. This article uses reinforcement sensitivity theory to examine the effect of individual differences in the Behavioral Inhibition System (BIS) on the behavioral and cognitive intentions to engage in violence after exposure to misinformation online. Using an online panel sample (Mechanical Turk), and a behavioral study that involved exposure to, and interaction with, misinformation, this study found that trait BIS score impacted how much individuals engaged with misinformation, as well as their ensuing activism and radicalism toward the narratives that were depicted. This study identified that engagement with misinformation impacted intentions for activism and radicalism, as did trait BIS. However, these effects were present for both misinformation and correct information conditions. These findings highlight the importance of BIS-related processes and raise important questions about the degree to which we need to think about online influence as a general process versus specific processes that directly relate to the effect of misinformation.

Radicalization Processes and Transitional Phases in Female and Male Detainees Residing in Dutch Terrorism Wings.

BACKGROUND: Radicalization, violent extremism, and terrorism are risks to societal security. Although research on terrorism-related behaviors is increasing, thorough empirical studies are rare. METHODS: This study investigates radicalization processes and transitions in a matched sample of female and male terrorist suspects and convicts (N = 26) residing in Dutch penitentiary terrorism wings. RESULTS: Results show that both men and women often experienced discrimination. A subgroup of women grew up in a stressful family environment and lacked emotional support from their family, whereas the other women did not experience such circumstances. The majority of the study sample was susceptible to connecting with radicalized friends or family members. Interestingly, factors that initially led to radicalization (e.g., a utopian image of the Islamic State) could later turn out to be factors associated with abandoning extremism. CONCLUSIONS: In this study, differences in radicalization processes and transitional phases between women and men emerged. Men more often had police contact prior to a terrorism-related offense. Making an effort to right old mistakes seemed important in the radicalization processes of men, whereas women had a stronger desire for emotional support and were more driven by experienced trauma and feelings of loneliness. This study provides input for gender-specific prevention and disengagement interventions.

Understanding Collective Human Behavior in Social Media Networks Via the Dynamical Hypothesis: Applications to Radicalization and Conspiratorial Beliefs.

The dynamical hypothesis has served to explore the ways in which cognitive agents can be understood dynamically and considered dynamical systems. Originally used to explain simple physical systems as a metaphor for cognition (i.e., the Watt governor) and eventually more complex animal systems (e.g., bird flocks), we argue that the dynamical hypothesis is among the most viable approaches to understanding pressing modern-day issues that arise from collective human behavior in online social networks. First, we discuss how the dynamical hypothesis is positioned to describe, predict, and explain the time-evolving nature of complex systems. Next, we adopt an interdisciplinary perspective to describe how online social networks are appropriately understood as dynamical systems. We introduce a dynamical modeling approach to reveal information about emergent properties in social media, where radicalized conspiratorial beliefs arise via coordination between user-level and community-level comments. Lastly, we contrast how the dynamical hypothesis differs from alternatives in explaining collective human behavior in social networks.

YouTube's recommendation algorithm is left-leaning in the United States.

With over two billion monthly active users, YouTube currently shapes the landscape of online political video consumption, with 25% of adults in the United States regularly consuming political content via the platform. Considering that nearly three-quarters of the videos watched on YouTube are delivered via its recommendation algorithm, the propensity of this algorithm to create echo chambers and deliver extremist content has been an active area of research. However, it is unclear whether the algorithm may exhibit political leanings toward either the Left or Right. To fill this gap, we constructed archetypal users across six personas in the US political context, ranging from Far Left to Far Right. Utilizing these users, we performed a controlled experiment in which they consumed over eight months worth of videos and were recommended over 120,000 unique videos. We find that while the algorithm pulls users away from political extremes, this pull is asymmetric, with users being pulled away from Far Right content stronger than from Far Left. Furthermore, we show that the recommendations made by the algorithm skew left even when the user does not have a watch history. Our results raise questions on whether the recommendation algorithms of social media platforms in general, and YouTube, in particular, should exhibit political biases, and the wide-reaching societal and political implications that such biases could entail.

COVID-19 and Sinophobia: Detecting Warning Signs of Radicalization on Twitter and Reddit.

Hate crimes and hateful rhetoric targeting individuals of Asian descent have increased since the outbreak of COVID-19. These troubling trends have heightened concerns about the role of the Internet in facilitating radicalization. This article explores the existence of three warning signs of radicalization-fixation, group identification, and energy bursts-using data from Twitter and Reddit. Data were collected before and after the outbreak of COVID-19 to assess the role of the pandemic in affecting social media behavior. Using computational social science and Natural Language Processing techniques, we looked for signs of radicalization targeting China or Chinese individuals. Results show that fixation on the terms China and Chinese increased on Twitter and Reddit after the pandemic began. Moreover, tweets and posts containing either of these terms became more hateful, offensive, and negative after the outbreak. We also found evidence of individuals identifying more closely with a particular group, or adopting an "us vs. them" mentality, after the outbreak of COVID-19. These findings were especially prominent in subreddits catering to self-identified Republicans and Conservatives. Finally, we detected bursts of activity on Twitter and Reddit following the start of the pandemic. These warning signs suggest COVID-19 may have had a radicalizing effect on some social media users. This work is important because it not only shows the potential radicalizing effect of the pandemic, but also demonstrates the ability to detect warning signs of radicalization on social media. This is critical, as detecting warning signs of radicalization can potentially help curb hate-fueled violence.

Radicalization from a societal perspective.

Studies on radicalization tend to focus on the dynamics of extremist groups and how they exploit grievances of vulnerable individuals. It is imperative, however, to also understand the societal factors that lead to such vulnerabilities and grievances. Our social environment plays a key role in how we view the world and shape our beliefs. By understanding the social dynamics, we can gain insight into the motivations that drive people to extremism. Throughout this paper, we examine the societal factors and processes such as discriminative institutional structures and social norms/practices that can make an individual vulnerable and serve as a driving force for them to join a radical group. To do that, we use the process-oriented psychology of Arnold Mindell and the phenomenology of whiteness of Sara Ahmed as our theoretical framework. These frameworks help us map out the societal dynamics causing individuals to carve social niches out of their current social group and into an extremist group. We use interviews with ex-militants of the radical group, Islamic State of Iraq and Syria, to show how certain societal dynamics, such as social injustice, misuse of power, marginalization and discrimination, served as key factors that led these individuals to identify and sympathize with radical ideology. The aim of this paper is to emphasize that, to develop effective preventative measures against recruitment into extremist groups, it is imperative to have a profound understanding of the social dynamics that make an individual susceptible to radicalization in the first place.

Seven years of studying the associations between political polarization and problematic information: a literature review.

This literature review examines the intersection between political polarization and problematic information, two phenomena prominent in recent events like the 2016 Trump election and the 2020 COVID-19 pandemic. We analyzed 68 studies out of over 7,000 records using quantitative and qualitative methods. Our review revealed a lack of research on the relationship between political polarization and problematic information and a shortage of theoretical consideration of these phenomena. Additionally, US samples and Twitter and Facebook were frequently analyzed. The review also found that surveys and experiments were commonly used, with polarization significantly predicting problematic information consumption and sharing.

Radicalization and violent extremism depend on envy; conspiracy ideation, sometimes.

Emotions are conspicuous components of radicalization, violent extremism, and conspiracy ideation. Of the emotions studied for their contribution to those social pathologies, envy has been relatively unexplored. We investigate the relationship between envy, radicalization, and conspiracy ideation. Envy appears to affect core aspects of radicalization, particularly the endorsement of extremism and the acceptance of violent means to achieve one's ends, while radicalization facilitates the adoption of conspiracy ideation, rather than the latter being a cause of radicalization. Implications for future research on radicalization and violent extremism are discussed.

Extreme Reactions to Globalization: Investigating Indirect, Longitudinal, and Experimental Effects of the Globalization-Radicalization Nexus.

Radicalization-as a complex process of adopting extremist attitudes-includes maladaptive responses to the transformative power of globalization. Globalization contains sociocultural disruptive and acculturative processes, initiating exclusionary and integrative reactions. These reactions have dissimilarly been associated with aspects of extremism. In seven preregistered studies (N = 2,161), we draw on various methods combining naturalistic circumstances, cross-sectional, longitudinal, experimental, and representative data to scrutinize the complex globalization-radicalization nexus within the contexts of the United States, the United Kingdom, and Pakistan. Our results provide empirical support for the hypothesis that insecure life attachment (i.e., experience of contextual safety, inclusiveness, reliability, fairness, and facilitating well-being) and globalization perceived as a threat can lead to extremism through defensive reactions to globalization. Specifically, we found ethnic protection to be a central mechanism connecting sociocultural disruption and threats with extremism. Globalized radicalization ascends as a contemporary phenomenon reflecting the dark side of global interconnectivity.

Why Is It so Difficult to Investigate Violent Radicalization?

Imagine that you are a researcher interested in disentangling the underlying mechanisms that motivate certain individuals to self-sacrifice for a group or an ideology. Now, visualize that you are one of a few privileged that have the possibility of interviewing people who have been involved in some of the most dramatic terrorist attacks in history. What should you do? Most investigations focused on terrorism do not include empirical data and just a handful of fortunate have made face-to-face interviews with these individuals. Therefore, we might conclude that most experts in the field have not directly met the challenge of experiencing studying violent radicalization in person. As members of a research team who have talked with individuals under risk of radicalization, current, and former terrorists, our main goal with this manuscript is to synopsize a series of ten potential barriers that those interested in the subject might find when making fieldwork, and alternatives to solve them. If all the efforts made by investigators could save the life of a potential victim, prevent an individual from becoming radicalized, or make him/her decide to abandon the violence associated with terrorism, all our work will have been worthwhile.

Collective case formulation in situations of violent radicalization: A critical perspective in training.

Case formulation is used in clinical training to weave together theoretical perspectives and support a shared plan of action. Although a cornerstone of clinical practice, critical social theorists have highlighted the risks of depoliticizing political struggles and of reifying and fixing subjects when using psychopathology and case formulation to address situations of injustice. In the field of violent radicalization, this risk is increased by the extreme affects evoked by terror in practitioners and in societies. This article explores the challenges of training clinicians in the field of violent radicalization. It does so by analyzing a Community of Practice (CoP) that was developed to support practitioners involved in this domain of practice in Quebec, Canada. Four focus groups with CoP participants and participant observation of nine CoP meetings were conducted. Thematic and narrative analyses were used to explore the training potential of the CoP and to identify the discursive processes and group dynamics associated with this modality. Results indicate that the diversity of professional perspectives and social positionalities in the group plays a central role in helping participants become aware of their biases and in developing more complex understandings of cases and of their social embedding. Results also suggest that the collective holding of risk is key to preserve practitioners' investment in patients involved with violent radicalization. The sensitive issue of partnership between health and social services and security agencies is also addressed. Results suggest that CoPs with strong leadership allow for experiential training to enhance clinical and critical thinking.

The Necessity to Recognize Processes of Radicalization from a Socio-cultural Perspective.

The current paper investigates Psychoanalytic, Cognitive, Behaviorist, and Socio-cultural theories and critiques how they have (or might have) contributed to the study of radicalization. The paper asserts two arguments that lack emphasis in the current radicalization research: 1) radicalization refers to a process, and does not always refer to violent behavior; 2) radicalization research needs to pay tribute to socio-cultural, political, and historical context while designing research and discussing findings. These two points are essential to extend the concept of radicalization and to be sensitive to different research contexts and populations. Currently, the conceptualization of radicalization appears to be generalized to violent action among minority groups (mainly Muslims) in limited contexts (mostly Western countries). The article claims that Psychology can better contribute to this diverse field of interest with its well-established theoretical contributions to the understanding of human beings and its compassion to seek differences amongst people across different contexts.

The Making of a Radical: The Role of Peer Harassment in Youth Political Radicalism.

Although political radicalism is one of the major societal threats, we have limited understanding of how it is formed. While there are reasons to expect that harassment experienced in adolescence increase the propensity for radicalism, this relationship has not yet been investigated. This five-wave study of Swedish adolescents (N = 892) examined the role of peer harassment in radical political behavior. The results revealed that within-person fluctuations in harassment were positively related to fluctuations in radicalism. Individual-level (but not class-level) harassment also predicted differences between adolescents: youth who experienced more harassment had higher levels of and a more pronounced decrease in radicalism. In addition, adolescents who had more supportive teachers or parents were less affected by harassment than youth with less-supportive adults. The findings suggest that personal experiences of harassment increase the risk of radicalism but supportive relationships can mitigate their negative consequences.
