The Psychology of Adolescence: Online Radicalization and the Child in the Next Room

The New Ecology of Adolescent Development

Adolescent development has always involved the integration of peer influence, family values, cultural narratives, and the young person's own emerging sense of self. What has changed over the past two decades is the arrival of a new primary influence that has altered the entire ecology. The smartphone, and the internet it provides, means adolescents now spend enormous portions of their waking lives in digital environments shaped by commercial and algorithmic logic rather than by the supervisory adults who once mediated cultural influence. The adolescent of 2025 is not the adolescent of 2005 with a phone added. They are, in significant ways, a different kind of developing person, forming under conditions no previous generation has navigated. Rising rates of anxiety, depression, and suicidality have tracked alongside near-universal smartphone use, and most contemporary scholars accept that digital media is contributing meaningfully to adolescent mental health difficulties.

The Manosphere and the Boys It Targets

What Adolescence foregrounds with unusual care is a specific subset of these concerns. Adolescent boys in particular are being exposed to content ecosystems that researchers have come to call the manosphere, a loose collection of online communities, content creators, and ideological frameworks that propagate specific views about gender, sexuality, and what young men are owed by the world. The content varies considerably. Some is relatively innocuous. Some is actively misogynistic. Some is organized around what has come to be called incel ideology, in which young men who have not had romantic or sexual success come to blame women, feminism, and broader social structures for their perceived deprivation. The most radicalized versions of these communities have produced actual violence, both in several high-profile mass killings over the past decade and in everyday acts of harassment and abuse, including, as the show depicts, violence against a female peer.

The Parent Who Did Not Know

The show's most devastating character is Jamie's father Eddie. Eddie is not a bad father. He loves his son, has been present in the household, and has provided for his family. He does not drink excessively, does not abuse his wife, does not beat his children. By any reasonable historical standard of fatherhood, he has been performing the role adequately. What the show slowly reveals is that adequacy by historical standards did not translate into the specific kind of attention his particular son, in his particular moment, needed. Eddie did not know what Jamie was watching, what communities he was engaging with, or what ideas he was absorbing. His son was in the next room, for years of evenings, being shaped by influences Eddie had no awareness of. The gulf between what Eddie thought was happening and what was actually happening is the show's central horror, and research bears it out. Parents consistently overestimate their knowledge of their children's online lives, and the gap is structural rather than the result of any single parental failure, because these environments are designed to be opaque to outside observers.

What Radicalization Looks Like From Inside

The show's third episode, depicting Jamie's extended conversation with a forensic psychologist, is the most substantive depiction of adolescent radicalization currently available in mainstream television. For most of the conversation Jamie is charming, articulate, and seemingly reasonable. He makes arguments that have internal coherence within the framework he has absorbed, then at specific moments reveals patterns of thinking the viewer recognizes as alarming, even when he does not. What the episode demonstrates is that radicalization does not typically present as obvious extremism. The radicalized adolescent is usually a young person who appears to be functioning normally while holding, beneath their social presentation, beliefs shaped by the content they have consumed. Those beliefs surface in the framing of particular situations and in the categories the young person applies to the people around them. Research on radicalization shows the process unfolds through stages rather than arriving suddenly. Young people are often drawn in first for belonging, identity, and explanatory frameworks that make sense of what they have been struggling with, and the ideological commitments become, over time, the price of continued belonging.

The Specific Vulnerabilities of Adolescent Boys

Adolescent boys carry specific vulnerabilities that certain online communities have been skilled at exploiting. The developmental tasks of early adolescence include establishing identity, navigating emerging sexuality, building peer relationships, and integrating self-esteem with an increasingly complex social environment. Boys face these tasks within cultural expectations that often restrict their emotional expression, demand specific performances of masculinity, and tie social worth to forms of achievement many boys have no realistic immediate access to. The boy who is struggling socially, academically, or romantically is, under these conditions, in a state of significant psychological vulnerability, often carrying shame, disappointment, and anger he has no approved outlet for. Into that interior state arrives content that does two things. It validates the feelings he has been carrying, and it offers an explanatory framework that externalizes responsibility for his difficulties onto specific others, often women, while offering membership in a community of similarly aggrieved peers. The young man who has been radicalized does not, in his own mind, hate women unreasonably. He believes he has come to understand the truth of his situation, and that distortion is part of what the ideology is designed to obscure.

The Victim Who Becomes Invisible

One of the show's most quietly devastating choices is to keep the murdered girl, Katie, largely at the edges of its attention. The show is making a difficult point through its narrative architecture. Katie is largely invisible in the show because she was largely invisible in Jamie's worldview. The ideology he had absorbed did not permit him to see her as a full human being. This reflects a documented feature of how radicalized violence often operates. The victim is not, in the perpetrator's mind, fully a person at the moment of the violence. Through extended ideological immersion, the perpetrator develops a way of seeing certain categories of people that diminishes their reality, so the specific individual becomes thinner, less real, less present to conscience than the category they have been made to represent. This pattern has been documented across studies of genocide, terrorism, and interpersonal violence. The show asks what it would have required for Katie's full personhood to have remained real to Jamie throughout his radicalization, and implies the answer would have involved interruptions at every stage of his formation that did not occur.

The Burden the Parents Carry

The fourth episode, set about a year after the events of the first three, follows Jamie's parents trying to continue with their lives after his conviction. They are still married, still parenting younger children, and navigating a world in which their family has become the subject of public horror. What the episode depicts is a form of grief and trauma our cultural frameworks have not fully developed language for. The parents of perpetrators of serious violence carry a burden that overlaps with but is distinct from other forms of bereavement. They have lost the child they thought they were raising, while still loving and parenting the child who exists, and they must contain the knowledge that he has caused profound harm to another family. The social isolation that accompanies this position is nearly total. The show's gentle insistence on the humanity of Jamie's parents is not an exculpation of what their son has done. It is an insistence that the conditions which permit such children to be formed are structural rather than individual, and that treating parents as uniquely guilty will not address them.

Reflections for the Viewer

For parents of adolescent boys, the show functions as a forced confrontation with questions many have been avoiding. What is my son actually engaging with online? What communities is he part of? What ideas is he absorbing? What would I need to know to recognize that something concerning is developing? The questions are uncomfortable precisely because most parents cannot answer them fully, and the show's value lies in its insistence that they be asked anyway. The practical invitations are clear. Learn about the specific content ecosystems your son may be encountering. Have ongoing conversations about what he is watching and thinking about. Pay attention to the frameworks he uses when he describes the people around him, particularly women and girls. Take seriously any concerning patterns, including derogatory language, specific grievances about female peers, or formulations that match the vocabulary of known online communities. Resist the temptation to assume your son is insulated because he seems like a good kid, because most of the radicalized adolescents in real cases were considered good kids until they were discovered not to be. The protective factors are not exotic. They include connection, attention to a boy's interior life, communities organized around interests rather than grievances, and the willingness to seek trusted adults, mental health professionals, or school resources when concerns arise. Many of these protective habits grow from the same ground as teaching emotional regulation and building confidence in children.
