Cluster B Personality Traits in Extreme Environments
Individuals with Cluster B personality disorders — which include Antisocial, Borderline, Histrionic, and Narcissistic Personality Disorders — can have significant and sometimes destabilizing effects on team dynamics, especially in extreme environments (e.g., military operations, polar expeditions, deep-sea missions, or spaceflight). These environments demand trust, cohesion, emotional regulation, and resilience, making them particularly sensitive to interpersonal dysfunction.

Expeditionary Risk and Resilience Framework
Cluster B Personality Disorders include:
Antisocial
Borderline
Histrionic
Narcissistic
These traits are marked by emotional dysregulation, interpersonal volatility, impulsivity, and unstable self-concept, which can severely affect team functioning in high-stakes, high-stress environments like combat zones, deep expeditions, polar research, or spaceflight.

Potential Negative Impacts on Team Functioning:
Cluster B Personality Risk Matrix (Boling, 2025).
1. Disruption of Cohesion and Trust
Antisocial traits may lead to rule-breaking, deception, or disregard for others' safety or well-being.
Narcissistic traits can manifest as entitlement, dismissiveness of others’ input, and monopolizing leadership or credit.
These behaviors can erode mutual trust, which is essential for survival and effective performance in extreme settings.
2. Emotional Volatility
Individuals with Borderline Personality Disorder may exhibit intense mood swings, fear of abandonment, and unstable relationships.
In high-stress, confined environments, emotional dysregulation can lead to conflicts, withdrawal, or crises that require team resources to manage.
3. Manipulation and Polarization
Histrionic or narcissistic individuals may manipulate others for attention or validation.
This can cause splits within the team, with alliances forming around or against certain individuals, disrupting cohesion.
4. Impulsivity and Risk-Taking
Antisocial and borderline traits often involve impulsivity and poor risk assessment.
In extreme environments, impulsive behavior can jeopardize group safety (e.g., not following protocol, sabotaging equipment, escalating interpersonal tension).
5. Authority Conflicts
Individuals with Cluster B traits may challenge leadership, especially under perceived threats to ego or autonomy.
In mission-critical scenarios, insubordination or resistance to authority can delay decisions or cause mission failure.

Possible Strengths (if well-managed):
In some controlled settings or with therapeutic support, Cluster B traits can be channeled constructively:
Traits or Potential Strength in Extreme Environments
Narcissistic High confidence, charisma, willingness to lead under pressure.
Borderline High emotional sensitivity can lead to deep empathy and intuitive group awareness.
Antisocial Fearlessness, boldness, risk tolerance in danger.
Histrionic Morale boosting, enthusiasm, and emotional expressiveness.
However, these strengths require a high degree of self-awareness, training, or therapeutic containment — which is rarely present without support.
Clinical Considerations
Screening for personality pathology is critical in high-stakes team selection.
Preventative measures like psychological support, resilience training, and clear behavioral protocols can mitigate risk.
Psychedelic-assisted therapy (such as with ayahuasca) is being explored as a possible treatment for emotional dysregulation and maladaptive personality traits, which could theoretically reduce the interpersonal harm caused by Cluster B traits in team settings.

Applied Framework: Managing Cluster B Traits in High-Stakes Teams
1. Selection & Preparation Phase
Psychological Screening: Use MMPI-2, PAI, or SCID-5-PD to identify Cluster B traits early.
Simulated Stress Scenarios: Observe behavior under pressure to flag destabilizing patterns.
Psychoeducation: Teach recruits about emotional regulation, triggers, and healthy team roles.
2. Deployment/Expedition Phase
Behavioral Contracts: Pre-set expectations for conduct, accountability, and team roles.
Structured Communication Channels: Daily briefings, emotional check-ins, and conflict debriefs.
Team Containment Roles: Assign peer-support officers or rotating conflict mediators.
3. Crisis Response
Rapid De-escalation Protocols: Train the team in recognizing signs of emotional destabilization or manipulative behavior.
Remote Support Access: Tele-psychology tools or embedded clinicians when possible.
Isolated Recovery Zones: Temporary containment (physical or social) for dysregulated individuals.
4. Post-Mission Reintegration
Therapeutic Debriefing: Evaluate impact on team mental health, address trauma or fallout.
Leadership Debriefs: Reflect on what worked or failed in interpersonal dynamics.
Longitudinal Monitoring: Flag individuals with recurring difficulties for future role reassignment.
