Violence Risk Assessment Of Sovereign Citizens: An Exploratory Examination Of The Hcr-20 Version 3 And The Trap-18, Lee Vargen, Darin Challacombe

Psychology Faculty Publications

Sovereign Citizens comprise an understudied right-wing extremist movement in the United States who have grown in notoriety in recent years due to several high- profile instances of violence. Despite this, little empirical research has been conducted on Sovereign Citizens, including research on assessing their risk for violence. In this study, we sought to replicate and extend a prior study on Sovereign Citizen violence. Using open-source data, we added several new cases to a pre-existing dataset of violent and non-violent Sovereign Citizen incidents, yielding a total sample of 107 cases. We scored each case using the HCR-20V3 and TRAP-18 risk assessment …

The January 6th Insurrection At The U.S. Capitol: What The Trap-18 Can Tell Us About The Participants, Darin Challacombe, Carol Patrick

Psychology Faculty Publications

On January 6, 2021, hundreds of individuals converged on and breached the U.S. Capitol building in an effort to overturn the presidential election results. For the present study, open-source research was conducted on 101 federally indicted participants of this event—half of whom were indicted on assault or other violent felony crimes and the other half for trespassing or nonviolent misdemeanor charges. Then, we used the Terrorism Radicalization Assessment Protocol (TRAP-18; Meloy & Gill, 2016) to examine these Capitol insurrection participants indicted for their actions. Four proximal warning behaviors and one distal behavior were significantly found to be related to the …

Key Leadership Roles In The 9/11 Terrorist Attack, Aubrey Immelman

Psychology Faculty Publications

Personality assessment of three al-Qaida leaders in the September 11, 2001 terrorist attack on the United States – Osama bin Laden, Ayman al-Zawahiri, and Mohamed Atta – provides evidence for a rudimentary model of the leadership roles required for a global-reach terrorist operation: (1) a narcissistic, charismatic leader devoid of core values beyond personal self-interest, adept at exploiting others in pursuit of his grandiose ambitions (e.g., bin Laden); (2) a strategic-thinking “true believer” without constraints of conscience regarding the level of violence he is willing to employ in his single-minded pursuit of mission (e.g., al-Zawahiri); and (3) unobtrusive, disciplined operatives …

“Bin Laden’S Brain”: The Abrasively Negativistic Personality Of Dr. Ayman Al-Zawahiri, Aubrey Immelman, Kathryn Kuhlmann

Psychology Faculty Publications

This paper presents the results of an indirect assessment of the personality of Ayman al-Zawahiri, deputy leader of the al-Qaida terrorist network at the time of the September 11, 2001 terrorist attack on the United States and allegedly chief strategist for al-Qaida operations and personal physician to Osama bin Laden.

Al-Zawahiri’s primary personality patterns were found to be Contentious/oppositional and Dominant/controlling, with secondary features of the Dauntless/dissenting and Ambitious/self-serving patterns.

The amalgam of Contentious (negativistic, or passive-aggressive) and Dominant (aggressive, or sadistic) patterns in al-Zawahiri’s profile suggests the presence of the “abrasive negativist” syndrome. For these personalities, minor frictions easily …

Psychology Faculty Publications

This paper presents the results of an indirect assessment of the personality of Osama bin Laden, founder and leader of the al-Qaida terrorist network responsible for the September 11, 2001 terrorist attack on the United States.

Bin Laden’s primary personality patterns were found to be Ambitious/exploitative and Dauntless/dissenting, with a secondary Distrusting/suspicious orientation, and subsidiary Dominant/controlling and Conscientious/dutiful features.

Ambitious individuals are bold, competitive, and self-assured; they easily assume leadership roles, expect others to recognize their special qualities, and often act as though entitled. Dauntless individuals are bold, courageous, and tough; minimally constrained by the norms of society; routinely engage …

The Personality Profile Of September 11 Hijack Ringleader Mohamed Atta, Aubrey Immelman

Psychology Faculty Publications

This paper presents the results of a posthumous, indirect assessment of the personality of Mohamed Atta, apparent ringleader in the September 11, 2001 terror attack on the World Trade Center and the Pentagon, from the conceptual perspective of Theodore Millon.

Information concerning Mohamed Atta was collected from media reports in the one-month period following the attack and synthesized into a personality profile using the second edition of the Millon Inventory of Diagnostic Criteria (MIDC), which yields 34 normal and maladaptive personality classifications congruent with Axis II of DSM-IV.

The personality profile yielded by the MIDC was analyzed on the …
