Navigating the cognitive challenges of incident command
At 0545, you arrive as the first officer on scene, and ultimately the incident commander, to a residential structure with smoke showing. A woman runs across the street screaming, “He’s in there! He’s in there!” You immediately position your vehicle past the building. You, along with another firefighter, who arrived in a POV, attempt to breach the front door, but you’re unsuccessful. It appears there is something heavy against the door. Law enforcement advises that they can’t make entry into the rear.
The first engine arrives, the crew is advancing a line to the front door, but they’re delayed entering as the crew can’t easily force the front door due to the heavy weight behind it (a couch). Once entry is made, they don’t have any water as the apparatus operator can’t engage the pump. The urgency builds, the frustration creates anxiety. How do you handle this mounting stress?
Those who are in command, as well as those with supervisory roles at an emergency incident, are the difference between operating effectively and experiencing critical failures. On the fireground, an incident commander (IC) must act as the “band leader.” Think Doc Severinsen or Questlove — a conductor who may or may not play an instrument, but utilizes cognitive clarity and open situational awareness to coordinate a complex group of “tactical musicians.” These leaders are developed in the day-to-day life of the firehouse; they are then forged under fire on the fireground, where the road to good intentions is frequently paved with chaotic uncertainties. Steve Martin, in the movie “Roxanne,” is a great study of this transition from technical expert to understanding how to work through the mental demands of leadership.
To lead effectively in the modern era, an officer must transition from a technical expert to a “human factors coordinator.” These factors are the performance influences variables that dictate how a supervisor interacts with their team, their tools, and the incident itself (U.S. Fire Administration, n.d.). By understanding these as dynamic influences, a leader can actively manage the biological, cognitive, and systemic variables that either sharpen or dull their ability to achieve a state of “calming calamity.”
I. The Biological Cost of Command
Leadership at an incident scene is a psychological and physiological event, full of mental gymnastics. Your thoughts and decisions don’t come from osmosis; they come from a complex set of interactions in your brain and body. High-stress environments create a “biological cost” that can degrade mental and physical performance, regardless of years of experience.
Limbic System Limbo
The limbic system controls your emotional reactions to various stimuli. Think of the limbic system as a game of limbo: you’re trying to flex your mind while the incident activities (the bar) challenge you to work in an increasingly tighter and more restrictive space.
● The amygdala (the alarm system):“Danger, Danger Will Robinson.” The robot from “Lost in Space” exclaims loudly, and he waves his metallic arms wildly, exemplifying this part of the brain’s function. Located deep in the temporal lobe, the amygdala is the brain’s primitive alarm system. Under extreme stress, it becomes hyperactive, triggering a fight-or-flight response that can “hijack” rational thinking (LeDoux, 1996). This often results in tunnel vision and impulsive decisions, such as reacting immediately to a single radio report of persons trapped without assessing the broader strategic picture of fire spreading and the impact it will have on rescue efforts.
● **The prefrontal cortex (the executive center):**The PFC is the brain’s executive center, responsible for complex decision-making, working memory, and strategic planning. Col. John “Hannibal” Smith of the “A-Team” exemplifies this role of the master planner. His well-recognized and relatable quote, “I love it when a plan comes together,” as well as, “I believe that no matter how random things might appear, there’s still a plan,” exemplifies this process. The PFC likes to work in a calm, chill environment — on the beach with a drink in your hand. However, under high stress, PFC function degrades significantly (Arnsten, 2009). When you have a report of a mayday in heavy fire and no water simultaneously, the PFC goes, “I’m checking out,” and your ability to juggle tactical priorities is mentally reduced.
Memory and Error Monitoring
● **The hippocampus (the memory bank):**The hippocampus is vital for retrieving learned protocols and past experiences to provide context for decisions. In the movie “Rain Man,” set in the late 1980s, Charlie (Tom Cruise) asks his brother Ray (Dustin Hoffman), who lives with autism, when he moved away. Without a pause, Ray answers, “Jan. 12, 1965. Very snowy that day, 7.2 inches of snow that day,” showing an amazing memory recall. Under pressure, your memory bank is impaired, potentially leading to lapses where established tactical sequences — like a mayday protocol — are simply forgotten. Ask anyone who has been a real mayday if they followed LUNAR.
● **The Anterior Cingulate Cortex (ACC) (The Error Monitor):**This serves as the “error Monitor,” detecting discrepancies between expected and actual outcomes. In “The Empire Strikes Back,” Luke’s X-wing fighter sinks into a bog. Luke stares at the ship, defeated. He engages in the following conversation with Yoda:
Yoda: “So certain are you. Always with you, it cannot be done. Hear you nothing that I say?”
Luke: “Master, moving stones around is one thing, but this is totally different!”
Yoda: “No. No different! Only different in your mind. You must unlearn what you have learned.”
Luke: “I’ll give it a try.”
Yoda immediately cuts him off: “No! Try not. Do, or do not. There is no try.”
Yoda points out the discrepancy and the error of not continuing until you succeed. If Luke followed his emotional perspective, failure is more likely. When overwhelmed by stress, this monitor can fail (Sapolsky, 2017), causing a supervisor to miss critical signs of bricks pushing out of a corner of a building during an imminent building collapse, or fail to notice when an extrication is taking too long while the patient is declining.
II. Acute Psychological Stressors: The In-Incident Impact
On the scene, psychological degradation is the erosion of your human size-up. In this context, sensemaking is the “internal size-up” — the mental bridge between seeing a problem and solving it. For firefighters, sensemaking is your brain’s ability to “connect the dots” during a rapidly evolving incident. When stress exceeds cognitive capacity, this process fails:
● **Cognitive narrowing (tunnel vision):**As stress increases, your field of vision constricts. You may become obsessed with a single tactical problem — like the heavy weight behind that front door — while your brain subconsciously ignores looking for other means of entry, like a nearby window.
● **Decision paralysis vs. impulsivity:**The mind oscillates between freezing from the fear of a wrong choice (paralysis) or defaulting to the first available thought without filtering (impulsivity/premature closure). An example of impulsivity is leading off with a 1 ¾ line for heavy fire throughout a two-story building, as opposed to a 2 ½, because the 1 ¾ is usually your default line.
● **Loss of self-efficacy:**Stress erodes your belief in your ability to control the outcome, leading to a psychological “surrender” to the calamity, where the leader stops directing and starts merely reacting. Instead of planning ahead with an overturned tanker of acetone and shutting down traffic, you just concentrate on stopping the leak because you’re not sure of your ability to make the right decision.
● **Emotional dysregulation:**Maintaining command presence is psychological labor. Degradation manifests as snapping at subordinates or frantic radio transmissions, which act as a “contagion”****that degrades the stability of the entire crew. (Goleman, 1995). Stress is building up as the fire is progressing on a rancher where you are shorthanded. You “snap” at the crew for not making a “knock” on the fire, as well as demanding the second engine “step it up” when traffic is heavy on the highway. Yet the real problem is not enough manpower and the wrong lines on the fire.
III. Chronic Performance Influences: Life
Psychological degradation is not confined to the emergency scene. Stressors from your personal life create a “baseline” level of wear that lowers your cognitive ceiling before you even turn the ignition. Every unresolved issue at home is a background program running on your brain’s “hard drive,” stealing the processing power you need for the fireground.
Kiel Samsing, author of “Mind of Fire”**and lieutenant at Newport News Fire, provides more detail on this critical element of performance: “What we do on our days off directly shapes how we perform on our days on. Before I leave for work, I run myself through the IMSAFE checklist: illness, medication effects, stress, alcohol, fatigue, and emotions or eating. Taking responsibility for your physical and mental state is one of the most important risk-management decisions you will ever make.”
● **The cumulative load:**This is the slow erosion caused by the “third rail,” which is that high voltage train track of life that carries those stressors of emergency services and personal life: sleep deprivation, traumatic calls, and administrative friction (Gilmartin, 2002). Over time, this wear-and-tear reduces your psychological tolerance, meaning you will reach task saturation much faster on a call because your brain is already partially occupied with the “load of life.” You’re only concentrating on removing a door during an extrication, when the patient is bleeding out from their leg and could benefit from a tourniquet.
● **Family and financial stress:**If you are worried about a pending divorce, a child struggling in school, or how you’re going to pay for a major home repair, your prefrontal cortex is already compromised. You arrive on scene with less “cognitive RAM” available to process the 0545 residential fire.
● **Moral injury:**This is a deep psychological wound that occurs when you witness or participate in actions (e.g., cheating on your spouse) that go against your core values (Van der Kolk, 2014). It acts as a constant distraction, making it harder to maintain the “calming calamity” mindset when others are looking to you to provide control and strategic vision at an incident.
The human brain is not built to process endless streams of data, and when we push it past the limits of the prefrontal cortex, performance drops (Sweller, 1988). It’s like trying to run modern software on an outdated machine.
The result:****These life challenges don’t just make you “stressed,” they make you cognitively vulnerable, which leads to burnout. A leader who is flourishing personally has a high ceiling for chaos. A leader burdened by chronic life stressors is starting the incident at the “limbo bar” level, with loss of mental flexibility. One more complication, like a pump failure or a report of people trapped, and they will crash into the red zone.
IV. Physiological Degradation: The Body’s Rebellion
These internal conflicts manifest in measurable, often unrecognized, yet dangerous physiological stressors. Like when you find out at that 0545 residential fire, it’s one of your firefighters’ houses, and he’s the one trapped. Your sympathetic nervous system doesn’t just “activate,” it floods your body with adrenaline and cortisol. Acute stress can spike heart rates to 150+ BPM within seconds (Grossman, 2008). That creates a cascade of physical and mental challenges:
● You begin to experience auditory exclusion, a phenomenon where your brain literally “mutes” voices and the radio near you. You may be staring at a firefighter on “the tip,” watching his lips move, but hearing absolutely nothing because your brain has decided that processing sound is a “luxury” it can no longer afford. This is accompanied by peripheral narrowing, or tunnel vision, where your psychological field of vision shrinks to a tiny point. You might see the victim in the window with crystal clarity, but you are physically incapable of seeing the power lines sagging two feet above your head or the fire venting from the “bravo” side.
● This degradation quickly moves into your hands and feet. It begins with the loss of fine motor coordination. Suddenly, you can’t hit the right button on the portable radio or or write on a command board. As the heart rate climbs and the “limbo bar” drops further, it progresses to the loss of complex motor skills and eventually gross motor skills. In extreme cases, a supervisor might find themselves physically unable to climb a ladder or even maintain a steady gait. You are no longer the band leader conducting a symphony; you’re a passenger in a body that has prioritized its own survival over the strategic objectives of the incident.
V. Cognitive Load and Task Saturation
Cognitive load is the mental effort required to manage an incident. This leads from an optimal load (green zone) to task saturation (red zone), where mental capacity is completely overwhelmed (Cohen-Hatton, 2019). Warning signs include repeating the same questions, forgetting assignments, or becoming fixated on minor details. Lt. Kiel Samsing provides deeper insight into this issue: “A wealth of information creates a poverty of attention. When data exceeds the brain’s capacity, performance drops. More knowledge eventually produces diminishing, and even negative, returns.”
VI. Mental Traps: Cognitive Biases
Incident commanders are highly susceptible to cognitive biases, subconscious shortcuts that lead to errors (Kahneman, 2011):
● **Confirmation bias:**This is defined as favoring information that confirms existing beliefs. If you decide the fire is in the basement, you recognize the smoke coming from the lower parts of the structure, while not looking for or ignoring additional cues and clues that could indicate there’s also fire in other locations.
● **Anchoring bias:**Relying too heavily on the first piece of information received (the dispatch report says “everyone out,” so you disregard having your crews do a search and clear the building.
● **Availability heuristic:**Overestimating the risk and benefit of an event because you recently saw a vivid example of it. You saw someone fall through a roof at a residential fire on YouTube last week, and now you’re at a commercial industrial building fire, and you won’t commit anyone to the roof due to that memory.
● Premature closure:Settling on a single plan too early and closing your mind to new, incoming information because “this is just a bread and butter fire,” and not paying attention to the increasing fire spread on side C. These cognitive shortcuts are not unique to the fireground; they have been documented in other high-stakes environments where decision-making failed under pressure(Vaughan, 1996).
The Transition: The Internal Size-Up
In this article, we have identified the biological, emotional, cognitive, and environmental influences on command and supervisory leadership while operating at emergency incidents. We have provided insight into the inner workings of your body and brain as it relates to leading and managing people and resources while trying to carry out tactical objectives.
We know your biology, life stressors, and mental shortcuts are constantly influencing every move you make as a supervisor. You’re operating with a brain that is hard-wired to fail you the moment the heat is turned up.
But how do we actually make the choices that lead to the “I love it when a plan comes together“ moment? Why do some experts thrive in this chaos while others crumble?
In an upcoming article, we’ll move from the influences to the mechanics of how the gears turn and engage in the decision-making process.
