The corporate world has widely adopted the “Avoid, Deny, Defend” (ADD) framework as the standard response to active shooter events. Developed by the Advanced Law Enforcement Rapid Response Training (ALERRT) center, this three-step model is taught in countless workplaces, schools, and public institutions. While its simplicity makes it easy to remember, the ADD strategy is fundamentally flawed as a comprehensive survival guide. Its linear, one-size-fits-all approach fails to account for the chaotic, fluid nature of real-world shootings and may actually increase risk by encouraging passive behaviors that play into a shooter’s hands.

The Illusion of a Simple Solution

The core problem with “Avoid, Deny, Defend” is that it presents a sequential checklist for a situation that is anything but sequential. Active shooter events are dynamic and unpredictable; the “correct” response changes from second to second based on the shooter’s location, weapon, tactics, and the environment itself. By teaching a fixed order of operations—first try to evacuate, then if you can’t, hide, and only as a last resort fight—the model creates a dangerous mental rigidity. It trains people to think in terms of a predetermined script rather than to constantly assess and adapt to the rapidly evolving threat.

This mental rigidity is particularly dangerous because of how the human brain processes information under extreme stress. When confronted with a life-threatening situation, the brain’s amygdala triggers a fight-or-flight response that narrows attention and limits cognitive flexibility. Training that emphasizes a rigid sequence of actions can exacerbate this narrowing effect, creating what psychologists call “script dependence.” In this state, individuals become mentally locked into following the trained sequence even when circumstances clearly demand a different approach. Research from the Federal Law Enforcement Training Center (FLETC) indicates that training emphasizing decision-making under dangerous and rapidly changing conditions produces better outcomes than training focused on memorized sequences.

Consider a practical scenario: an employee in a corporate office hears gunshots. The “Avoid, Deny, Defend” model tells them to first attempt evacuation. But what if the shots are coming from the only exit? What if they’re in an open-plan office with no clear line of sight to any exit? What if they’re with a group of people, some of whom are injured? The linear model provides no guidance for these nuances. It assumes a clean, step-by-step progression that rarely exists in reality. Studies of actual active shooter events reveal that the situations people face are messy, overlapping, and constantly changing. A shooter might move between rooms, double back, or be joined by an accomplice. The environment might contain multiple hazards beyond the shooter—broken glass, locked doors, confused crowds. A model that prescribes a fixed sequence cannot account for this complexity.

Furthermore, the sequential nature of the model creates a dangerous delay in decision-making. By conditioning people to think “first avoid, then deny, then defend,” it introduces a cognitive lag as individuals mentally check off each option before moving to the next. In an environment where fractions of a second matter, this delay can be fatal. The Homeland Security Affairs journal published research indicating that the most critical piece of training is to use the Run, Hide, Fight model “but not in a linear fashion.” The study found that continuous assessment of the situation, varying between the modes, allows the active shooter event to dictate the path of response. Understanding that running does not have to be the first response, that hiding does not need to follow running, and that fighting is not the last resort is vital.

The psychological impact of this rigidity extends beyond the immediate event. When individuals are trained to follow a rigid script and then find themselves in a situation where that script doesn’t apply, they may experience what researchers call “cognitive freezing”—a state of paralysis where the brain cannot process information or make decisions. This is distinct from the natural “freeze” response to threat; it’s a specific failure of trained decision-making systems. After-action reports from numerous incidents describe victims who were found in positions suggesting they were trying to follow trained protocols that didn’t fit their actual circumstances—hiding under desks when they should have been running, or running into dead ends when they should have been barricading.

The model also fails to account for the variable nature of threat environments. An active shooter in a classroom presents different challenges than one in a shopping mall, which differs again from one in an office building. Each environment has its own geometry, its own resources, its own potential for cover and concealment. A fixed sequence ignores these environmental differences. Research on combat shooting training emphasizes the importance of “task ambiguity”—the recognition that real-world situations contain multiple, overlapping variables that cannot be addressed by simple protocols. Training that reduces this ambiguity through linear sequences may actually reduce survivability by failing to prepare people for the ambiguity they will actually face.

Perhaps most insidiously, the model’s simplicity creates a false sense of preparedness. Organizations that implement “Avoid, Deny, Defend” training often believe they have adequately prepared their people for an active shooter event. This can lead to complacency—a belief that because a plan exists, the plan will work. But as security experts note, active shooters don’t snap, they plan. They develop tactics, conduct reconnaissance, and adapt their approach based on expected responses. A linear model provides predictability that a planning shooter can exploit. If shooters know that potential victims will first try to evacuate, they can position themselves to target evacuation routes. If they know people will hide under desks, they can systematically check under desks. The model’s predictability becomes a vulnerability.

The alternative is not to abandon structured training but to replace linear sequences with adaptive frameworks. This means training people in principles rather than scripts—teaching them to recognize danger, assess options, and make decisions based on the specific circumstances. It means emphasizing continuous situational awareness, the ability to recognize when conditions have changed, and the psychological flexibility to abandon a plan that isn’t working. Research from ecological dynamics in combat training suggests that training should develop “enskilled” individuals who can navigate uncertain and ambiguous surroundings through adaptive perception and action. This type of training acknowledges complexity rather than trying to simplify it away.

In essence, the “illusion of a simple solution” is that complex, dynamic problems can be solved with simple, static solutions. Active shooter events are among the most complex, dynamic situations a person can face. To survive them requires not a checklist but a mindset—one that embraces uncertainty, values adaptability, and recognizes that the only constant in such events is change.

The Flaw in “Avoid”: Evacuation Isn’t Always Possible or Safe

The first step, “Avoid,” urges people to evacuate the area if it can be done safely. In theory, this is sound advice; creating distance from danger is always preferable. However, the model often fails to adequately stress the critical word: “safely.” The assumption that evacuation is generally the best first option overlooks the complex realities of how people actually behave under extreme stress and how building environments can turn evacuation routes into death traps.

Research on human behavior during emergencies reveals that panic fundamentally alters decision-making capabilities. When confronted with an immediate threat, the brain’s prefrontal cortex—the center for rational thought and risk assessment—becomes overwhelmed by the amygdala’s fear response. This neurological hijacking produces predictable behaviors that directly contradict safe evacuation. People experience tunnel vision, narrowing their visual field to approximately 10-15 degrees, which means they literally cannot see alternative exits or potential dangers to their sides. Auditory exclusion occurs, making it difficult to hear warnings or the direction of gunfire. And most critically, the ability to process complex information collapses, reducing people to simple, often fatal heuristics.

The “herd mentality” that emerges during panic creates some of the most dangerous evacuation scenarios. Studies of crowd behavior in emergencies consistently show that people follow the crowd, even when the crowd is moving toward danger. During the 2003 Rhode Island nightclub fire, people swarmed toward the main exit while ignoring multiple other exits, resulting in dozens of deaths. In active shooter situations, this same phenomenon occurs: people will run toward what they perceive as the main exit, even if the shooter is positioned near it, because the crowd is moving that direction. Agent-based modeling research has demonstrated that this herding behavior can increase evacuation time by 30-40% and significantly increase casualty rates.

Building design plays a critical role in whether evacuation is even feasible. Research from ScienceDirect on building design and its effect on evacuation efficiency found that door and hallway widths have the most significant impact on evacuation speed and casualty levels. In many modern buildings, particularly open-plan offices and schools, doorways create bottlenecks that can trap people in hallways. The study found that a standard 36-inch doorway can only accommodate about 1.5 people per second in single-file movement, but under panic conditions, this rate drops dramatically as people push and shove. In a classroom with 30 students, evacuating through a single doorway would take approximately 20 seconds under ideal conditions—time that may not be available when a shooter is present.

The location and number of exits compound these challenges. Research from the University of Tennessee’s dissertation on active shooter evacuations found that the accessibility of exits nearest to the shooter plays a significant role in outcomes. In buildings where the primary exits are near the shooter’s location, people attempting to evacuate are forced to move toward the threat rather than away from it. High-rise buildings present particular challenges: stairwells become chokepoints, elevators are typically unsafe during active shooter events, and people on upper floors may be forced to choose between waiting for help or descending through potentially occupied stairwells.

Open-plan environments, common in modern offices, eliminate the natural barriers that might slow a shooter but also eliminate hiding places and create long lines of sight. In these environments, “evacuation” often means running across open spaces where the shooter has clear visual and tactical advantages. Research from the Naval Postgraduate School found that in open-plan settings, the mere act of running across a room can make someone a target, as movement attracts the shooter’s attention. The model’s advice to “evacuate if safe” provides no guidance on how to assess safety in these environments, where the very act of evacuation may be what makes the situation unsafe.

The FBI’s study of active shooter incidents between 2000 and 2013 found that 69.8% of incidents end in 5 minutes or less, with 23 ending in 2 minutes or less. This compressed timeframe fundamentally undermines the evacuation-first approach. In the 2018 Santa Fe High School shooting, the first shots were fired at 7:37 AM; by the time law enforcement arrived at 7:40 AM, 10 people were already dead. The idea that people can assess their surroundings, identify safe evacuation routes, and execute an orderly evacuation in this timeframe is unrealistic. Most people don’t even have time to process what’s happening, let alone execute a complex evacuation plan.

The model also fails to account for the reality that shooters often target evacuation routes. In the 2016 Pulse nightclub shooting, the shooter positioned himself near the main exit. In the 2017 Route 91 Harvest music festival shooting, the shooter fired into a crowd of people who had nowhere to evacuate. In the 2022 Robb Elementary School shooting, the shooter entered through a propped-open door—the same type of door that might serve as an evacuation route. Shooters who plan their attacks often consider evacuation patterns and may position themselves to maximize casualties among people attempting to flee.

Furthermore, the model’s emphasis on individual evacuation ignores the collective nature of many active shooter events. In schools, workplaces, and public venues, people are rarely alone. Evacuation decisions affect not just the individual but the group. One person’s decision to run can trigger a cascade of following behavior, potentially leading crowds into danger. Conversely, one person’s decision to barricade a door can protect dozens of others who cannot evacuate. The model’s individualistic focus fails to account for these group dynamics and the potential for coordinated responses that might be more effective than individual evacuation.

The psychological impact of failed evacuation attempts can be devastating. When people are trained to evacuate first and then find themselves in a situation where evacuation is impossible or suicidal, they may experience what psychologists call “learned helplessness”—a state where they believe their actions cannot affect the outcome, leading to passivity even when action might save lives. This is particularly dangerous because it can occur mid-event: a person who successfully evacuates one area may encounter the shooter in another and become paralyzed, having been conditioned to believe that evacuation is the correct response.

The alternative to the evacuation-first approach is continuous threat assessment combined with multiple response options. This means teaching people to evaluate their specific circumstances—shooter location, number of exits, group size, available cover—before deciding whether to evacuate. It means recognizing that in some situations, barricading a room may be safer than evacuating through potentially compromised routes. And it means understanding that the decision to evacuate or not must be constantly reassessed as the situation evolves. Research from the University of Tennessee found that optimal evacuation routing depends on real-time information about the shooter’s location, which is rarely available to civilians in the initial moments of an event.

In essence, the “Avoid” component of the model creates a false hierarchy of responses that may not match the reality of specific situations. While evacuation is often preferable, it is not always possible or safe, and the model’s failure to adequately address the complexities of evacuation under fire leaves people unprepared for the difficult calculations they must make in seconds. A more effective approach would teach principles of threat assessment rather than prescribing evacuation as the default first response.

The Danger of “Deny”: Hiding Is a Passive Trap

The second step, “Deny,” is perhaps the most problematic component of the “Avoid, Deny, Defend” model. It advises people to find a place to hide, lock and barricade the door, and wait for help. This is where the strategy becomes truly dangerous because it promotes a passive response in a situation that demands active survival. The instinct to hide is deeply rooted in human psychology; when faced with overwhelming danger, our brains often default to concealment as a protective mechanism. However, this natural impulse can be fatal in an active shooter scenario because it fails to account for the reality of how these events unfold.

Evidence from numerous shooting incidents shows that simply hiding, especially under desks or in thin-walled rooms, offers minimal protection. The critical distinction between cover and concealment is often lost in training: cover stops bullets, while concealment only hides you from view. Most hiding spots in typical office or school environments—under desks, behind drywall, in standard closets—provide concealment at best. A 9mm handgun round can easily penetrate multiple layers of drywall, and even rifle rounds can pass through interior walls with lethal force. The physical barriers that most people consider “hiding spots” are essentially meaningless against gunfire.

The Virginia Tech massacre provides a stark and tragic illustration of this danger. Analysis of the incident revealed that rooms where occupants played dead or hid under furniture had significantly higher fatality rates than those who barricaded doors or fought back. In Room 211 of Norris Hall, students were instructed to get under their desks when the shooter entered. The shooter methodically went from one desk to the next, shooting people who were hiding. Eleven students and a professor died in that room alone. The shooter re-entered the classroom multiple times, systematically targeting those who were concealed under desks. The very action that was supposed to protect them—hiding—made them stationary, predictable targets.

This pattern is not unique to Virginia Tech. In numerous active shooter incidents, perpetrators have demonstrated that they are not deterred by locked doors or hidden victims. Shooters often systematically move through spaces, shooting anyone they find, including those who are hiding. The FBI’s study of active shooter incidents between 2000 and 2013 found that in 63 incidents where the duration could be ascertained, 44 (69.8%) ended in 5 minutes or less, with 23 ending in 2 minutes or less. In this compressed timeframe, the luxury of waiting for help while hidden is often unavailable. The shooter is moving, and anyone who is static and hidden is simply waiting to be discovered.

Furthermore, “Deny” promotes a passive response that assumes the shooter will pass by, an assumption that is often fatally wrong. This assumption fails to account for several critical realities of active shooter behavior. First, many shooters are not random in their movements; they follow predetermined paths or systematically search for victims. Second, shooters can hear sounds—crying, breathing, phones ringing—that betray hidden individuals. Third, the psychological state of many shooters includes a determination to maximize casualties, which means they will often check hiding spots rather than simply passing them by.

The model also fails to account for shooters who are specifically looking for victims in hiding spots. Some shooters have been known to return to rooms they’ve already cleared, or to methodically check under desks and behind furniture. The very act of hiding can become a trap when the shooter is actively seeking out those who are concealed. In the Sandy Hook Elementary School shooting, the shooter went from classroom to classroom, shooting people who were hiding. The strategy of “deny” assumed a passive threat that would move on; the reality was an active threat that was systematically searching for victims.

Perhaps most insidiously, the “Deny” strategy creates a false sense of security that can delay critical decision-making. When people believe they are safe because they are hidden, they may fail to recognize when their situation has become untenable. They may remain in a hiding spot even when an escape route becomes available, or when the shooter is approaching their location. This psychological trap—feeling safe when you are not—can be more dangerous than the initial threat because it paralyzes the very decision-making that could save lives.

The alternative to passive hiding is active barricading combined with continuous assessment. This means not just finding a place to hide, but actively securing the space by barricading doors with heavy furniture, turning off lights, silencing phones, and positioning yourself away from doors and windows. More importantly, it means continuously reassessing whether your hiding spot remains viable, whether escape routes have opened up, and whether you need to transition from hiding to running or fighting. The goal is not to be passive and hope for the best, but to be proactive in creating the conditions for survival while remaining ready to adapt when circumstances change.

The Last Resort Myth of “Defend”

Finally, “Defend” is presented as the option of last resort—a desperate, high-risk action to be taken only when all else has failed. This framing is psychologically damaging because it conditions people to view self-defense as a failure rather than a viable, often necessary, tactic. By positioning “Defend” as the final, most dangerous option, the model discourages proactive action when it might be the most effective choice. It also ignores the fact that waiting for law enforcement, which can take crucial minutes, is itself a high-risk strategy. The psychological impact of this framing cannot be overstated; when people are trained to see fighting back as the worst-case scenario, they may hesitate at the very moment when decisive action could save lives.

Research from the FBI’s study of active shooter incidents between 2000 and 2013 reveals a startling reality that contradicts the “last resort” framing. The study identified 21 incidents (13.1% of the total) where unarmed citizens made the selfless and deeply personal choices to face the danger of an active shooter. In those instances, the citizens safely and successfully disrupted the shootings. In 11 of those 21 incidents, unarmed principals, teachers, other school staff, and students confronted the shooters to end the threat. In 10 incidents, citizens, working or shopping when the shootings began, successfully restrained shooters until police could arrive. These actions likely saved the lives of students and others present. The data suggests that fighting back is not merely a last resort but a statistically significant factor in ending active shooter incidents before law enforcement arrives.

The timing of these interventions is critical. The FBI study found that 69.8% of incidents ended in 5 minutes or less, with 23 ending in 2 minutes or less. In this compressed timeframe, waiting for law enforcement is often not an option. Even when law enforcement was present or able to respond within minutes, civilians often had to make life and death decisions. The study noted that in at least 65 incidents (40.6%), citizen engagement or the shooter committing suicide ended the shooting at the scene before law enforcement arrived. This reality fundamentally undermines the model’s assumption that fighting back should be reserved for when all else has failed—because in many cases, “all else” doesn’t have time to unfold.

Agent-based modeling research further supports the effectiveness of civilian resistance. A study using agent-based modeling explored the potential for limiting casualties should a small proportion of potential victims swarm a gunman, as occurred on a train from Amsterdam to Paris in 2015. Results suggest that even with a minuscule probability of overcoming a shooter—a 1 out of 100 chance for each second of the struggle—fighters may save lives but put themselves at increased risk. The modeling found that proactive measures such as fighting the shooter will lower the average casualty rate to 30 casualties compared to the average casualty rate of 63 casualties when the shooter is not subdued. While individuals who take proactive measures will be at a higher risk of casualty, their actions can significantly reduce the overall death toll.

The concept of collective action is particularly important. When individuals fight back together, their chances of success increase dramatically. Research on the 2015 Thalys train attack showed that coordinated group action—where multiple individuals simultaneously attacked the gunman—was effective in disarming him. This “swarm” approach disrupts the shooter’s focus and creates multiple threats that a single individual cannot adequately address. The model’s framing of fighting back as a solitary, last-ditch effort fails to account for the power of coordinated resistance.

Real-world examples abound of individuals who fought back successfully. In the 1997 Pearl High School shooting in Mississippi, assistant principal Joel Myrick retrieved a handgun from his car and confronted the shooter, ending the attack. In the 2001 Wedgewood Baptist Church shooting in Fort Worth, Texas, a congregant wrestled with the shooter, disarmed him, and held him until police arrived. In the 2018 Nashville Waffle House shooting, James Shaw Jr. wrestled the gun away from the shooter after the shooter’s weapon jammed. These examples illustrate that fighting back is not inherently suicidal but can be a calculated, effective response when the situation demands it.

The psychological impact of the “last resort” framing extends beyond the immediate event. When people are trained to view self-defense as failure, they may carry that mindset into future situations, becoming increasingly passive in the face of threat. This learned helplessness can be particularly damaging in environments where the threat of violence is ongoing. The model conditions people to see themselves as potential victims rather than potential actors, a mindset that can become self-fulfilling.

Furthermore, the model’s framing ignores the difference between reckless heroism and calculated resistance. Fighting back does not mean charging at a shooter with bare hands; it means using available resources—improvised weapons, numbers advantage, surprise, distraction—to create an opportunity for survival. It means recognizing when hiding is no longer viable and when taking action, however risky, offers a better chance of survival than remaining passive. The model fails to teach this critical distinction, lumping all forms of resistance together as dangerous last resorts.

The alternative is to reframe “Defend” not as a last resort but as a viable option that should be considered whenever it offers a better chance of survival than the alternatives. This means training people to recognize when fighting back is appropriate, how to use improvised weapons effectively, and how to coordinate with others for collective action. It means teaching the principles of self-defense—creating distance, using cover, targeting vulnerabilities—rather than simply presenting fighting as the final, desperate option. Research from combat training suggests that individuals who are trained in adaptive problem-solving and who understand the principles of resistance are more likely to survive than those who are trained to follow rigid scripts.

In essence, the “last resort” myth creates a false dichotomy between passive survival and active resistance. The reality is that survival often requires a combination of both, depending on the circumstances. By positioning fighting back as the worst-case scenario, the model may inadvertently increase casualties by discouraging the very actions that could save lives. The data suggests that civilian resistance is not a tragic necessity but a statistically significant factor in ending active shooter incidents. Recognizing this reality requires a fundamental shift in how we frame self-defense—from a failure to be avoided to a tool to be deployed when it offers the best chance of survival.

A Better Approach: Fluid, Adaptive Decision-Making

The alternative to a linear model is a dynamic, decision-making framework that emphasizes continuous situational assessment. This approach teaches individuals to constantly evaluate their environment and choose the best course of action based on the specific circumstances, rather than following a fixed sequence. It recognizes that running, hiding, and fighting are not steps in a checklist but tools that can be used in any order—or simultaneously—depending on the situation. For example, a person might need to fight immediately to create an escape route, or they might need to hide briefly before finding a way to evacuate. Training should focus on developing adaptive problem-solving skills, understanding the principles of cover versus concealment, and empowering individuals to take decisive action when it will increase their chances of survival.

The core principle of this approach is continuous situational assessment—a mental process where individuals constantly gather information about their environment, interpret that information, and make decisions based on their evolving understanding of the threat. This is not a passive state of awareness but an active, ongoing process of scanning, listening, and thinking. In an active shooter scenario, this means paying attention to the direction and pattern of gunfire, the location of exits and potential cover, the behavior of other people, and any changes in the shooter’s tactics. It means asking questions like: Where is the sound coming from? Is it getting closer or moving away? Are there people ahead of me who might be in danger? Is there a better hiding spot than the one I’m currently in? Can I reach an exit safely?

Research from the Naval Postgraduate School found that active shooter training may be more effective if instructions highlight the importance of constant situational assessment with an emphasis on the fluidity of the incident. Response decisions should change as the event evolves and dictates an appropriate response. The study concluded that the delivery of active shooter training should focus less on linear progression—first run, next hide, and then fight—and more on what the situation dictates to be the best response. This shift from scripted to adaptive training represents a fundamental change in how we prepare people for these events.

The concept of “perceptual awareness” is central to this approach. Rather than training people to look for specific cues that trigger specific responses, adaptive training teaches them to perceive the overall environment and recognize patterns that indicate danger or opportunity. This includes understanding the difference between cover and concealment, recognizing the sound of different calibers of gunfire, identifying potential improvised weapons, and assessing the emotional state of people around them. When individuals develop this perceptual awareness, they can make better decisions about when to run, when to hide, and when to fight—not based on a predetermined sequence, but on a real-time assessment of what will maximize their chances of survival.

The adaptive approach also recognizes that active shooter events are not static; they evolve over time. A shooter may change weapons, move to different locations, or encounter resistance that alters their behavior. People in the environment must be prepared to adapt their own strategies in response to these changes. This might mean transitioning from hiding to running when the shooter moves away, or from running to fighting when cornered. It might mean coordinating with others to create distractions or overwhelming force, or moving from one type of cover to another as the threat shifts. The key is flexibility—the ability to abandon a plan that isn’t working and develop a new one based on the current situation.

Training for this adaptive approach requires a different methodology than traditional active shooter training. Instead of lectures and simple drills, it uses immersive, scenario-based exercises that present trainees with complex, evolving situations. These scenarios are designed to be unpredictable, with multiple variables that change as the exercise progresses. Trainees must make decisions under stress, receive feedback on the consequences of those decisions, and then adapt their approach based on what they’ve learned. This type of training develops what researchers call “cognitive flexibility”—the ability to switch between different mental strategies in response to changing demands.

Virtual reality (VR) training has shown particular promise for developing adaptive decision-making skills. VR simulations can create immersive, realistic environments where trainees can practice making decisions under stress without the risks of live training. These simulations can present a wide variety of scenarios, from office buildings to schools to public spaces, each with its own unique challenges. They can also collect data on trainee decisions, providing detailed feedback on what worked and what didn’t. Research from the University of North Texas and University of Nevada Las Vegas found that immersive VR training allows for the collection of data on various what-if scenarios in response to active shooter events, which can be used to sharpen skills and improve response time.

The adaptive approach also emphasizes the importance of communication and coordination. In many active shooter events, people who work together have a better chance of survival than those who act alone. This might involve coordinating with colleagues to create a distraction while others escape, sharing information about the shooter’s location and movement, or working together to barricade a door. Training should teach people how to communicate effectively under stress, how to coordinate their actions with others, and how to make collective decisions that benefit the group as a whole.

Another critical component of the adaptive approach is understanding the psychological dimensions of survival. This includes recognizing and managing the fear response, overcoming the tendency to freeze or follow trained scripts, and maintaining the cognitive flexibility to make decisions under extreme stress. Training should include techniques for managing fear and stress, such as controlled breathing, positive self-talk, and visualization. It should also address the psychological barriers that prevent people from taking decisive action, such as the bystander effect or the assumption that someone else will take charge.

The adaptive approach recognizes that there is no one-size-fits-all solution to an active shooter event. What works in one situation may be disastrous in another. A person who successfully runs from a shooter in a shopping mall might be killed trying to run from a shooter in a narrow hallway. A person who successfully hides under a desk in a classroom might be killed hiding under a desk in an open office. A person who successfully fights back against a single shooter might be killed trying to fight back against multiple shooters. The adaptive approach teaches people to assess their specific circumstances and choose the strategy that offers the best chance of survival, rather than following a predetermined sequence that may not fit their situation.

This approach also acknowledges that survival is often a matter of timing. The same action—running, hiding, or fighting—can be either effective or deadly depending on when it is performed. Running too early might put someone in the shooter’s line of fire; running too late might mean missing an escape window. Hiding at the wrong time might leave someone trapped; hiding at the right time might provide crucial minutes for law enforcement to arrive. Fighting at the wrong time might be suicidal; fighting at the right time might save lives. The adaptive approach teaches people to recognize timing opportunities and act on them, rather than waiting for a predetermined sequence to unfold.

Ultimately, the adaptive approach represents a shift from teaching people what to do to teaching them how to think. Instead of providing a checklist of actions, it provides a framework for decision-making. Instead of training compliance, it trains judgment. Instead of preparing people for a specific scenario, it prepares them for the uncertainty and chaos of real-world events. This is a more challenging form of training, but it is also more effective because it equips people with the mental tools they need to navigate the unpredictable, rapidly evolving nature of active shooter incidents.

Conclusion

The “Avoid, Deny, Defend” model, while well-intentioned, represents a fundamental misunderstanding of how people survive complex, dynamic threats. Its greatest flaw lies not in its individual components—avoiding danger, denying access, and defending oneself are all sensible actions—but in its presentation as a sequential, linear process. Active shooter events are not linear; they are chaotic, fluid, and unpredictable. By reducing survival to a three-step checklist, the model creates a dangerous illusion of control in situations where control is impossible. It conditions people to think in terms of predetermined scripts rather than adaptive decision-making, and this mental rigidity can be fatal when circumstances deviate from the expected pattern.

The evidence presented in this essay demonstrates that each component of the model has significant limitations when applied as part of a rigid sequence. Evacuation, while generally preferable, is not always possible or safe, and the model provides insufficient guidance on how to assess evacuation routes under stress. Hiding, particularly in the passive form often taught, creates stationary, predictable targets and provides only concealment, not cover, against gunfire. The data from Virginia Tech and other incidents shows that hiding under furniture or in thin-walled rooms offers minimal protection against determined shooters. And framing self-defense as a last resort discourages proactive action that might be the most effective response in many situations, as FBI research shows that civilian resistance ends 13.1% of incidents before law enforcement arrives.

The alternative proposed throughout this essay—a fluid, adaptive decision-making framework—addresses these limitations by emphasizing continuous situational assessment over linear progression. This approach recognizes that the “correct” response changes from second to second based on the shooter’s location, tactics, and the environment itself. It teaches people to perceive their environment accurately, assess their options realistically, and make decisions based on the specific circumstances rather than a predetermined script. Research from the Naval Postgraduate School, FLETC, and numerous case studies supports this approach, finding that training which emphasizes adaptive decision-making produces better outcomes than training focused on memorized sequences.

The psychological dimensions of survival cannot be overlooked. The human brain under extreme stress tends to narrow attention and limit cognitive flexibility, making it difficult to deviate from trained responses. Adaptive training addresses this by developing what researchers call “cognitive flexibility”—the ability to switch between different mental strategies in response to changing demands. It also teaches stress management techniques and addresses psychological barriers like the bystander effect that can prevent decisive action. When people understand that survival often requires a combination of running, hiding, and fighting—and that these actions can be employed in any order depending on the situation—they are better prepared to navigate the chaos of real events.

The practical implications of this shift from linear to adaptive training are significant. Organizations must move beyond simple lectures and periodic drills to immersive, scenario-based exercises that present complex, evolving situations. Virtual reality training offers particular promise in this regard, allowing trainees to practice decision-making under stress without the risks of live training. Communication and coordination must be emphasized, as research shows that people who work together have better survival rates than those who act alone. And training must address the psychological dimensions of survival, including stress management and the overcoming of passive tendencies.

The stakes of this training evolution could not be higher. The FBI’s study of active shooter incidents between 2000 and 2013 found that 69.8% of incidents end in 5 minutes or less, with 23 ending in 2 minutes or less. In this compressed timeframe, the luxury of following a predetermined sequence is often unavailable. Civilians must make life-and-death decisions in seconds, and the training they receive must prepare them for this reality. The data shows that when people fight back—even with improvised weapons and minimal training—they can disrupt the shooter’s plan and save lives. By positioning self-defense as a last resort, the current model may inadvertently discourage the very actions that could prevent casualties.

Ultimately, the choice between a linear model and an adaptive framework is not merely academic; it has real consequences for real people in real situations. The “Avoid, Deny, Defend” model, for all its good intentions, may be creating a false sense of security while leaving people unprepared for the chaos they will actually face. The adaptive approach, while more complex to teach and learn, better reflects the reality of active shooter events and provides the mental tools needed to survive them. It shifts the focus from compliance to judgment, from scripts to principles, and from passive waiting to active decision-making. In the fight for survival, this shift could make the difference between life and death.

The path forward requires a fundamental rethinking of how we prepare civilians for active shooter events. It requires moving beyond the comforting simplicity of three-word slogans to the more challenging reality of adaptive decision-making. It requires recognizing that survival is not about following a script but about developing the judgment to assess situations accurately and act decisively. And it requires acknowledging that in the face of such threats, flexibility and proactive decision-making are far more valuable than adherence to a fixed script. The evidence is clear: the “Avoid, Deny, Defend” model, while well-intentioned, is not the best strategy for survival. The adaptive approach offers a more effective path forward—one that respects the complexity of the threat and empowers people to navigate it successfully.
