Introduction: Fear and Fight: A New and Better Understanding of Our Natural and Learned Responses to a Threat

As I wrote in my previous post, I have completed I have completed the first complete draft of the book that I've been researching and writing for the past ten years: Fear and Fight: A New and Better Understanding of Our Natural and Learned Responses to a Threat.

I shared the Preface to Fear and Fight in the previous post. In this post, I share the introduction:

Fear and Fight: A New and Better Understanding of Our Natural and Learned Responses to a Threat

CHAPTER 1

INTRODUCTION

The same survival mechanisms that kept our forefathers alive can help keep us alive as well! However, those survival mechanisms that can help us can also work against us if we don’t understand and anticipate their presence.

—U.S. Army Field Manual 3-5.70: Survival

 Bruce Siddle is an internationally recognised authority on use-of-force training and the effects of ‘survival stress’ on combat performance. In Sharpening the Warrior’s Edge, Siddle (1995) refers to the well-known ‘fight-or-flight response’ as the ‘survival stress response’ (SSR), describing it as an automatic physiological reaction that prepares the body to either fight or flee when exposed to a threat. This reaction enhances strength, speed, endurance, and pain tolerance—traits that evolved to increase an individual’s chances of survival in life-threatening situations.

 Siddle (2005) explains that the SSR is primarily activated under two conditions: when an individual perceives an imminent deadly force threat and when there is minimal time to respond to that threat. He suggests that a person walking towards us with a knife from a distance of 500 yards (457 metres) is unlikely to activate our SSR, whereas being surprised by the same threat at a distance of 10 feet (3 metres) will almost certainly trigger it.

 I have faced a knife-wielding assailant while unarmed on two separate occasions, both of which involved the element of surprise and occurred at distances of less than 10 feet (3 metres). Yet, on both occasions, I did not experience a SSR reaction. The SSR was selected for in nature because it provided a survival advantage when one’s life was threatened. Where was my SSR when my life was threatened by a knife-wielding assailant in two situations that involved both a distance of less than 10 feet (3 metres) and the element of surprise?

 Siddle (2005) suggests that while the SSR was advantageous in our evolutionary past, it can interfere with modern survival skills such as close-quarter combat, firearms use, or evasive driving. He (Siddle 1995) refers to this as a ‘combat paradox’: the same response that once ensured our survival can now undermine it in specific combat scenarios. This raises an intriguing question: were my survival prospects if fact enhanced because I didn’t experience a SSR in these critical moments? Either way, the question remains—why didn’t I experience a SSR which is evolutionarily designed to promote an individual’s survival when my survival was directly threatened on two separate occasions? This book is the product of my search for answers to those questions.

 ‘Fight Activities’

The original intended audience for this book included individuals involved or interested in martial arts, self-defence, combat sports, security (such as security officers, bodyguards, and crowd controllers), law enforcement, and the military. But how can these diverse pursuits be referred to collectively?

 What they all share is a core focus: they train individuals to fight—for different purposes, certainly, but the ability to fight remains central. For this reason, this book refers to them collectively as ‘Fight Activities.’

 ‘Fight Activities’

The initial intended audience of this book was those engaged or interested in martial arts, self-defence, combat sports, security (security officer, security bodyguard, crowd controller), law enforcement, and the military. How can those activities be referred to collectively? To answer that question, we first need to ask what those activities have in common. Those activities teach trainees to fight, to fight for a variety of reasons but to fight nonetheless. For that reason, those activities will be referred to collectively in this book as ‘Fight Activities.’

 Fear and Fight

Our principal natural response to a threat is the emotion of fear—and the action tendency of fear is flight. Fight is not an action tendency of fear, despite what many suggest when referring to fight-or-flight and stress response concepts to explain our natural reaction to threats. Fight Activities teach people how to fight—for a variety of reasons, but to fight nonetheless. They provide ways and means to overcome fear in order to fight. These methods, combined with the learned fight behaviours they instil, form our learned response to a threat.

 This book explores both our natural response—driven by fear—and our learned response, focusing on the ways Fight Activities help us manage fear in order to fight. That’s why this book is titled: Fear and Fight.

 A New and Better Understanding of Our Natural and Learned Responses to a Threat

The subtitle of this book reflects a desire to deepen our understanding of our natural and learned responses to threats. The process that produced this understanding is explained by the work of Gary Klein in Seeing What Others Don’t (2013), where he discusses how insights can lead to more comprehensive and useful perspectives.

 Klein defines insight as an accurate and profound understanding, suggesting that it brings forth a new understanding that did not previously exist. This new understanding is better because it is more accurate, comprehensive, and useful than prior knowledge. Throughout this book, I aim to share insights that contribute to a new and better understanding of our natural and learned responses to threats.

 One of Klein’s paths to insight is curiosity, captured in the simple yet powerful question: ‘What’s going on here?’ This question serves as a catalyst for exploration, driving individuals to seek answers. For me, this journey began with my own ‘What’s going on here?’ moment—sparked by my lack of a fight-or-flight response during two life-threatening situations. That initial question led to answers, which in turn sparked more questions and deeper insights, ultimately shaping my understanding of how we respond to threats.

 Klein emphasises that insights transform our understanding and, in many ways, change who we are. They can alter our understanding by shifting the central beliefs in the story we use to make sense of events. This ‘new understanding can give us new ideas about the kinds of actions we can take; it can redirect our attention, changing what we see; it can alter the emotions we feel; and it can affect what we desire’ (Klein 2013, p. 148). This book aspires to facilitate such transformations for readers, encouraging a shift in how they understand, think, feel, and act in relation to our responses to threats.

 A Personal Perspective: Generalised Anxiety Disorder and Panic Attacks

What makes this exploration particularly unique is my diagnosis of generalised anxiety disorder (GAD) with panic attacks, which offers me a distinctive insight into both our natural and learned responses to perceived threats. Living with GAD means that my brain often interprets harmless situations as threatening, triggering responses as though the danger were real. This allows me to experience firsthand the instinctive responses to perceived threats, with anxiety and fear being the principal reaction. At the same time, the treatment for GAD involves learning to manage these responses, closely mirroring the way military, law enforcement, and self-defence practitioners are trained to regulate fear in high-stress situations. This parallel between therapeutic interventions and combat training demonstrates how learned behaviours can modify our instinctive reactions. Through this personal lens, I have studied our responses from the inside out, gaining an intimate understanding of how we handle both real and imagined threats. My experience informs every chapter of this book, offering a unique perspective on the interplay between natural and learned responses to a threat.

 Structure of the Book

Many people refer to the fight-or-flight concept to explain our natural response to a threat. In Chapter Two, we will explore how this widely accepted concept is based on a limited and flawed understanding of human survival responses. However, an accurate understanding of fight-or-flight still forms the basis for a more comprehensive view of both our natural and learned responses to threats.

 Chapter Three shifts focus to stress, another widely cited concept for explaining our natural response to danger. Since stress theory is rooted in the fight-or-flight concept, it shares the same limitations and flaws. Furthermore, because stress theory emerged from medical and biological research emphasising its negative effects on health, it has skewed researchers’ understanding of how stress plays a role in our survival responses.

 As I sought an answer to why I did not experience a stress response when confronted by a knife-wielding assailant on two separate occasions, I discovered that stress can be understood as a process involving physiological, emotional, and behavioural components. While this did not explain my reaction, it pointed me toward a deeper exploration of the emotional aspect, which proved instrumental in developing a new and better understanding of threat responses.

 Chapter Four examines emotion. Emotion, for theorists, is more than just a feeling. It’s a multi-component response to significant threats and opportunities, evolved to give an individual a survival advantage. In this chapter, an emotion process model is presented that offers a more accurate, comprehensive, and useful way to understand threat responses. This model will be applied throughout the rest of the book to investigate our natural and learned responses to a threat.

 Fear and its close cousin, anxiety, are the focus of Chapter Five, followed by a critical analysis in Chapter Six: if fighting is instinctively tied to fear, why do Fight Activities teach methods for overcoming fear in order to fight?

 The chapters in Part II dissect the individual components of the emotion/survival process, initially focusing on fear, and explore how interventions by Fight Activities help individuals overcome fear to fight. Many of these interventions rely on reason to suppress the emotional response of fear. Chapter 14 delves into the separation of ‘passion and reason’ and its implications for self-defence and combat training.

 Part IV applies the theory developed in earlier chapters to real-world contexts, including military strategy and self-defence. These chapters serve as case studies, showcasing how understanding fear and learned behaviours can inform and improve practical applications in survival and combat settings.

 Finally, Part V transitions to the post-phase of violent encounters, focusing on posttraumatic stress disorder (PTSD). PTSD is explored in depth, applying the insights from this book to better understand the condition and its treatment, along with related disorders such as GAD. My own experience with GAD has provided a firsthand perspective on these mechanisms. In fact, it demonstrates that PTSD and GAD share many similarities, both as evolved survival mechanisms and in terms of their treatment.

 A Broader Audience

While this book began as an exploration for those involved in Fight Activities—martial artists, self-defence practitioners, law enforcement, and military personnel—it has grown to encompass a wider audience. The principles discussed have far-reaching applications, touching on how we all navigate fear, anxiety, and survival in both extreme and everyday situations. Whether confronting life’s unexpected challenges or simply standing up to talk in a meeting, this book offers valuable insights into mastering fear and emerging stronger. Ultimately, Fear and Fight is for anyone who faces anxiety and/or fear—whether in combat or in daily life—and seeks to gain a deeper understanding of both the natural and learned responses that guide us through these experiences.
