§0 Sammanfattning

Den som håller i grinden behöver aldrig själv gå igenom den.

A conviction becomes a weapon when someone other than the believer sets what is at stake and how low the threshold for action lies; the companion post called this the conviction gate, and this post calls its capture gate capture [D]. Organisations do it to recruits, amplifiers do it to unknown listeners, and grievance does it to the dispossessed; the result can point outward, as terror, or inward, as protest suicide [D]. The evidence does not support the popular picture of terrorists as madmen: group-based attackers rarely show psychopathology, while mental illness is more common among lone actors without being their sole cause [S]. The post explains mechanisms only: it gives no operational detail, quotes no manifesto, names no recent attacker, and treats self-immolation as a pattern that spreads by imitation, not as a meaningful end [D].

§1 Gate capture

The Conviction Gate (DRK-194) modelled the step from belief to action as $c \cdot V > \theta$: certainty times the value of acting, against a threshold [D]. Gate capture (proposed corpus term): the condition in which the value of acting, the threshold for action, or the certainty of the belief is set by an agent other than the believer, so that the believer's gate opens on someone else's terms [D].

Kruglanski and colleagues model radicalisation as a quest for significance: a loss of personal significance (humiliation, failure, exclusion), an ideological narrative that names violence as the way to regain it, and a network that validates the narrative and rewards the act (Kruglanski et al. 2014) [S]. In the gate's terms, the loss of significance empties the self, the narrative relocates $V$ into the cause, and the network lowers $\theta$ [D]. Moghaddam's "staircase" describes the same narrowing as successive floors on which fewer options remain, until violence is the only door still open (Moghaddam 2005) [S].

§2 Suicide terrorism

Atran's review found that suicide attackers are generally not poor, uneducated, socially isolated or mentally ill compared with their populations, and that the decisive factors lie in organisations that recruit, train and commemorate them (Atran 2003) [S]. Pape analysed suicide-attack campaigns and argued that they follow a strategic logic: organised groups use them to coerce democracies into withdrawing from territory the groups claim (Pape 2003) [S]. Against this, Lankford argued that many suicide attackers show suicidal motives and personal crises that the martyrdom framing conceals (Lankford 2013) [H]; his reading remains contested in the field.

The two positions are compatible with one structure [D]. The organisation captures the gate: it sets $V$ (martyrdom, honour, the cause), lowers $\theta$ (social reward, the group's expectation), and locks $c$ by isolating the recruit from disconfirmation [D]. Whether the recruit also carries private despair, as Lankford holds, changes who is recruitable, not who holds the gate [D].

§3 Lone actors and mental health

Corner & Gill compared lone-actor and group-based terrorists and found a markedly higher lifetime prevalence of mental illness among lone actors, while most lone actors still had no recorded diagnosis (Corner & Gill 2015) [S]. Their title names the point: mental illness and ideology are not alternative explanations, and treating them as a dichotomy misreads both (Corner & Gill 2015) [S]. The great majority of people with mental illness are never violent, and illness is one factor among grievance, ideology, opportunity and social context [E].

Gate reading: the lone actor appears to set his own gate, but rarely does so alone [D]. Where an illness disturbs the formation of conviction, as in The Conviction Gate (DRK-194), an ideology available in the surrounding culture can supply the content and the target, and online audiences can stand in for the group that lowers the threshold [D].

§4 Kaczynski: a case without quotation

Theodore Kaczynski carried out a bombing campaign between 1978 and 1995 that killed three people and injured twenty-three; he was arrested in 1996 and in January 1998 pleaded guilty in exchange for life imprisonment without parole [E]. The court-ordered competency evaluation found him competent to stand trial and gave a provisional diagnosis of schizophrenia, paranoid type, together with a paranoid personality disorder (Johnson 1998) [E]. He rejected the diagnosis and refused to let his lawyers build a defence on mental illness (Johnson 1998) [E]. Whether the provisional diagnosis was correct has been disputed since [H].

What the case shows for this post is narrow [D]. A conviction can be elaborated into an internally consistent doctrine over decades, and internal consistency is no evidence that the gate is working; a delusion and a doctrine can both be coherent [D]. The person who held this conviction also fought hardest against any reading of it as illness, which is the lock of §2 in the companion post, defending the explanation against the one disconfirmation that would have saved his life from the death penalty [D]. The post does not reproduce his text, because doing so serves the conviction, not the analysis [D].

§5 Stochastic terror and the demonised Other

Amman & Meloy describe stochastic terrorism as an interactive process among an originator who demonises a target, amplifiers who repeat the message, and receivers among whom an unpredictable few act; they attribute the coinage to the risk analyst Gordon Woo (Amman & Meloy 2021) [S]. Its defining property is that any single act is unpredictable while the rate of acts is not, which lets originators deny responsibility for each act they made likely (Amman & Meloy 2021) [S].

Berger defines extremism as the belief that an in-group's success or survival cannot be separated from hostile action against an out-group, and shows that extremist movements sell a crisis attributed to the out-group together with a solution that requires action against it (Berger 2018) [S]. Haslam's review distinguishes two forms of dehumanisation, denying others uniquely human traits and denying them human nature itself, both of which lower moral restraint against harming them (Haslam 2006) [S].

Stochastic terror is gate capture at a distance [D]. The originator never touches the receiver's gate directly; he raises $V$ by announcing an existential threat, lowers $\theta$ by dehumanising its bearers, and leaves the rest to statistics [D]. Narratives of foreign invasion and internal enemies on the far right, including claims that a population is being deliberately replaced, are a prominent current instance of this structure in Western countries [D]. The structure is not owned by one ideology: jihadist narratives of a war on Islam, and revolutionary narratives of class or system enemies, use the same crisis-and-solution form (Berger 2018) [S]. The test is the mechanism, not the camp [D].

§6 The self turned inward: protest suicide

Biggs compiled over five hundred cases of suicide as protest between 1963 and 2002 and traced the modern lineage to the Vietnamese monk Thích Quảng Đức in Saigon in 1963 (Biggs 2005) [S]. He found that such acts cluster in waves, spread by imitation across movements and countries, are rarely organised, and are generally not linked to violence against others (Biggs 2005) [S]. Later cases include Jan Palach in Prague in 1969, Mohamed Bouazizi in Tunisia in 2010, whose death preceded the uprisings of that winter, and a wave among Tibetans from 2009 that Biggs placed in the same international pattern (Biggs 2012) [E].

Imitation is the finding that governs how these acts should be written about [S]. Phillips showed that suicides in the United States rose after front-page suicide stories, the "Werther effect" (Phillips 1974) [S]. The WHO's guidance for media summarises the later evidence: widely disseminated stories of suicide are followed by more suicides, while stories of people who came through a suicidal crisis are followed by fewer (World Health Organization 2023) [S].

Gate reading: in protest suicide the conviction's $V$ is turned against the self, the one possession left to someone who has lost the rest [D]. That is precisely why the framing of such acts as a final, meaningful statement does harm: it raises $V$ for the next person reading [D]. Biggs's data show that this repertoire was learnt from one case and spread by its telling; it is a social contagion, not a law of dispossession [S]. Most people who lose everything do not do this, and many who once thought of it are alive and recovered; that is the story the evidence says to tell [D].

§7 Repairing the gate

If capture is the problem, repair returns the gate to the believer and restores thresholds that others cannot lower at will [D]. In the terms of the Earth Engine (DRK-193), this is governor work, not fuel work: the grievance and the conviction may stay, but the coupling between someone else's throttle and the believer's ignition is cut [D]. Restoring significance by legitimate routes reverses the first step of the significance quest (Kruglanski et al. 2014) [S]. Refusing to amplify demonisation, and refusing perpetrators the notoriety they seek, starve the stochastic process of its amplifiers [D]. Treatment for psychosis, and support for grief and loss, address the formation of conviction before anyone else can capture it [D].

The anti-totalisation principle of the Totalitarian Sheaf (DRK-125) is the corpus's own version of a working gate: no single section, however coherent, is allowed to force every other section to agree with it [D].

§8 Falsification (DRK-131)

F1: Capture, not pathology, in group attacks. §2 claims that group-based suicide attacks are driven by organisational capture of the gate rather than by attackers' psychopathology. Refuted if systematic studies of group-based attackers find rates of serious mental illness well above their source populations.

F2: Stochastic rate. §5 claims that demonising rhetoric from prominent originators raises the rate of attacks on the demonised group without predicting any single act. Refuted if, in time-series data with appropriate controls, peaks of such rhetoric show no association with later attack rates against the named targets.

F3: Contagion of protest suicide. §6 claims that protest suicide spreads by imitation. Refuted if, in Biggs's data and later series, acts are distributed in time no differently from chance after controlling for political events.

F4: Scope limit. The post makes no clinical claim about any named person; the Kaczynski section reports the court evaluation and its disputed status. It does not equate any ideology with another beyond the shared mechanism, and does not treat mental illness as a cause of violence. If F1–F3 fail, the sourced findings of §2–§6 stand as reported and the gate-capture reading is withdrawn.

§9 Provenance and leaks

  1. Authorship: Khrug supplied the topic list (suicide bombers, the Unabomber, mental health and lone-wolf offenders, stochastic terror, far-right amplification of foreign and internal threats, demonising the Other, self-immolation). Claude (Opus 5.5) drafted the post, the term gate capture and the falsifiers, and set the ground rules: no operational detail, no manifesto text, no names of recent attackers, and safe-messaging practice for the section on suicide.
  2. The Kaczynski chronology (1978–1995, three killed, twenty-three injured, 1998 plea) is standard public record and was not checked against court documents beyond the competency report.
  3. The claim in §5 that "replacement" narratives are prominent in current far-right rhetoric is stated as the corpus's reading of public discourse; no quantitative source was verified for its prevalence. Statements of individual attackers were deliberately not cited.
  4. Biggs (2012) is cited without page numbers; the Palach and Bouazizi cases are textbook history.
  5. Lankford (2013) and the 2010 Tunisian case's causal role in the uprisings are contested or simplified and are tagged accordingly.
  6. The helpline details (Mind Självmordslinjen 90101, 112, findahelpline.com) should be checked before each republication.
  7. New term gate capture (§1) added to static/data/ko.json and approved on 2026-10-02 under Khrug's standing default, with the §1 definition as its verbatim defining sentence.
