Primary specialties: Human performance under stress, automaticity, cognition, decision-making, motor learning, firearms and tactics instruction, instructor development, and evidence-based training
Professional Biography
John Hearne is a retired federal law-enforcement officer, longtime Rangemaster staff instructor, firearms and tactics educator, competitive shooter, researcher, and founder of Two Pillars Training. He is best known for translating research from psychology, neuroscience, motor learning, evolutionary biology, and related fields into practical instruction on armed self-defense and performance under extreme stress.
Hearne’s public-safety career began in 1986. He served as a federal law-enforcement officer from 1992 through 2023 and retired as a field supervisor. His assignments included uniformed patrol, field training, plainclothes and surveillance work, anti-poaching operations, high-profile security, search and rescue, structural fire suppression, emergency medicine, use-of-force instruction, and agency prosecution.
He also served as a Field Training Officer, Field Training Supervisor, and member of the National Park Service’s National Field Training Advisory Committee. This broad experience gave him an unusually detailed view of how people acquire professional skills, how instructors evaluate performance, and how competence changes when the environment becomes uncertain or consequential.
Instruction and Two Pillars Training
Hearne has taught with Rangemaster since 2001, providing handgun, shotgun, rifle, instructor-development, and tactics instruction to private citizens, law-enforcement personnel, and military units. His documented instructional experience also includes National Park Service programs and work with personnel from the 20th Special Forces Group, Marine Corps high-risk-personnel training cadre, and National Guard military-police units.
In 2021, Hearne founded Two Pillars Training and expanded a curriculum centered on the person operating the weapon rather than the weapon alone. Two Pillars continues to offer his signature lecture and live-fire courses, including Who Wins, Who Loses, and Why and Cognitive Pistol.
Human Performance Under Stress
Who Wins, Who Loses, and Why: Understanding Human Performance When Death Is on the Line examines why some people retain useful performance during high-consequence events while others experience substantial degradation. Hearne approaches the question through research on stress, cognition, emotional regulation, learning, automaticity, pattern recognition, physical preparation, and decision-making rather than relying on inherited firearms folklore alone.
His central contribution can be stated simply: firearms performance under pressure is fundamentally a human-performance problem. Equipment matters, but identical equipment cannot explain why different people respond differently when time, uncertainty, fear, and consequence compress their ability to think and act.
Automaticity, Overlearning, and Cognitive Capacity
Hearne is particularly associated with explaining automaticity—the ability to perform a learned task with reduced conscious attentional demand. A shooter who must consciously manage every element of a draw, presentation, trigger press, or reload has less mental capacity available for identifying threats, communicating, moving, protecting bystanders, and making legal decisions.
The goal is not mindless action. Properly learned mechanical skills reduce cognitive cost so the person can devote attention to the decisions that actually require thought. Hearne’s discussion of overlearning similarly distinguishes performing a task correctly once from developing a durable skill that remains accessible after time has passed and under substantial pressure.
Cognitive Pistol and Instructor Development
Hearne’s Cognitive Pistol coursework combines firearms manipulation with perception, discrimination, decision-making, and tactical-anatomy problems. This moves training beyond isolated marksmanship and requires the shooter to process information while maintaining safe and accountable weapon handling.
His work is especially valuable to instructors because it challenges weak measures of learning. A successful repetition at the end of a training block may demonstrate temporary performance, not durable retention or reliable access under stress. Hearne encourages trainers to examine what the student has actually learned, how deeply it has been encoded, and what conditions may prevent the skill from remaining available.
Additional Professional Contributions
Hearne’s professional record includes competitive success in pistol, rifle, shotgun, and multi-gun events, along with recognition as a Top Practitioner at the National Tactical Invitational. He also developed reactive firearms-training targets and detailed SIG pistol and AR-15/M16 armorer inspection checklists used by multiple agencies. These contributions reflect the same preference for observable, repeatable, and testable performance.
Primary & Secondary Connection
Hearne has contributed to Primary & Secondary discussions of training, automaticity, cognition, tactical anatomy, decision-making, and performance under stress. Within the Extended P&S Network, he represents an evidence-based approach to instructor development: retain what survives scrutiny, revise what does not, and build training around how people actually learn and perform.
