Two soldiers experience the same explosion. One returns home and gradually readjusts to civilian life. The other develops PTSD, jumping at sudden sounds and showing erratic and violent behavior. How come?
What determines who walks away unscathed and who carries invisible wounds? The answer is not what we think we know about trauma. The amount of misinformation has given us the wrong impression.
The Event Is Not as Important as We Have Come to Believe
Most people still think that trauma is about what happens to them. In reality, it’s about what happens inside us when something overwhelming occurs—and when our system can’t process and resolve that fear or the assumptions of how negative the experience is.
I defined trauma in my book Traumatization and Its Aftermath as long-lasting disruption of an individual’s neurobiological, psychological, and social functioning resulting from unresolved emotional and physiological responses to overwhelming experiences perceived as threatening and defeating.
Notice the key words “unresolved” and “perceived.” This isn’t about the objective severity of an event; it’s about whether your system can successfully metabolize what happened. And notice the word “defeating,” which is pointing to the important fact that if we don’t find solutions, our brain can’t either.
When “Ordinary” Events Become Traumatizing
Consider these scenarios:
- Imagine a 6-year-old watching their mother collapse from exhaustion. To an adult observer, this might seem like a manageable situation. But for a child whose survival depends entirely on their mother’s well-being, this moment can feel like facing their own death. Without understanding that Mommy may just need rest, their developing brain may interpret this as, “The person who keeps me alive is gone.”
- Or imagine a successful executive losing their job during company downsizing. Objectively, this happens to millions of people who eventually find new employment. But if this person’s identity and sense of worth are entirely tied to their career success, the loss can feel like social death—imagining rejection from friends and community, and most probably a lot of shame and disapproval from their family.
The Hidden Power of Perception
What makes these experiences potentially traumatizing isn’t their objective severity; it’s how they perceive them, and the meaning the person assigns to them. When someone’s mental state becomes defeating, when they feel they can’t overcome the situation, or when hope disappears, the brain shifts into emergency mode and the whole system loses its balance.
This explains why the same event can affect people so differently. The soldier who recovers may have strong internal resources, social support, or previous experiences that help them contextualize explosions as dangerous but survivable events. The one who develops PTSD might lack these protective factors, leaving their nervous system at the mercy of inefficient mechanisms that assume danger is imminent.
The Paradox of “Obviously” Traumatic Events
Even events that seem obviously traumatic—serious accidents, natural disasters, violent crimes—don’t automatically traumatize everyone who experiences them. Why not?
Because humans are remarkably resilient and our brain is always trying to work as optimally as possible. We have sophisticated internal mechanisms for assessing risk, developing solutions, and accessing hope. When these systems work properly, even genuinely dangerous experiences can be processed and integrated without lasting disruption.
Consider emergency responders who regularly witness horrific scenes yet maintain their emotional stability. Their training provides cognitive frameworks for understanding what they’re seeing, their team offers social support, and their role gives them agency in helping others. These factors help their nervous system avoid the “defeat” response that characterizes traumatization.
3 Critical Factors
Research reveals three key elements that determine whether an experience becomes traumatizing:
- Overwhelm. Does the experience exceed your current capacity to cope? This varies dramatically based on age, previous experiences, current stress levels, and available resources.
- Perceived helplessness. Do you believe you have any control or agency in the situation? The same car accident might traumatize a passenger while leaving the driver (who maintained some sense of control) relatively unaffected.
- Meaning-making. How do you interpret what happened? Someone who views their cancer diagnosis as “a battle I can fight” may fare better than someone who sees it as “proof that life is randomly cruel.”
The Hope Factor
Perhaps most importantly, traumatization occurs when hope disappears—when someone believes their situation is permanent, unchangeable, and insurmountable. This is why the same divorce might devastate one person while freeing another, or why identical childhood experiences leave siblings with completely different outcomes.
The person who maintains some sense that “this too shall pass” or “I can survive this” engages different neurobiological pathways than someone who concludes “this will never end” or “I’ll never recover.”
Redefining Traumatizing
So what makes an experience traumatizing? The psychological relationship to a traumatic event or circumstance that an individual perceives as potentially life-threatening or harmful to their continued existence or well-being—that’s what makes the difference.
This definition shifts our focus from cataloging “traumatic events” to understanding individual responses. It explains why some people can face objective horrors without lasting damage because they don’t get trapped in narratives of victimization or defeat, while other individuals might be deeply affected by experiences others would dismiss as minor.
This perspective offers hope rather than despair. If trauma is primarily about how we process experiences rather than the experiences themselves, then healing becomes possible. Understanding that your reaction makes sense given your unique circumstances, resources, and perception can be the first step toward recovery.
Your nervous system’s response to overwhelming experiences reflects its wisdom, not your weakness. Sometimes that intelligence responds to outdated protective patterns—but with understanding and appropriate support, it can learn to update its threat assessment and find its way back to balance.
The goal isn’t to become invulnerable to all difficult experiences, but to strengthen your capacity to process them successfully when they inevitably arise.
