We don’t talk about it. Usually, we pretend it isn't there, lurking behind our morning coffee and our career goals and the way we obsess over our social media feeds. But it’s there. Sheldon Solomon, Jeff Greenberg, and Tom Pyszczynski call it the worm at the core. It’s the paralyzing, subconscious terror of our own inevitable demise.
Death.
It sounds grim. Honestly, it is. But according to Terror Management Theory (TMT), this singular realization—that we are biological organisms destined to rot—is the primary driver of almost everything humans have ever built. From the Pyramids of Giza to your 401(k) plan, it all stems from a need to manage the existential dread that sits in the back of our brains like a heavy weight. If we didn't have ways to buffer this fear, we’d probably just sit in a dark room and scream until the end came. Instead, we create art. We go to war. We buy expensive cars to feel "significant."
What Terror Management Theory Actually Says
The term "the worm at the core" actually traces back to the philosopher William James. He used it to describe the "essential fly in the ointment" of human happiness. Basically, he argued that no matter how good life gets, the knowledge of death is always there, nibbling away at our joy.
In the late 20th century, Solomon, Greenberg, and Pyszczynski took this philosophical idea and turned it into hard science. They were heavily influenced by Ernest Becker’s 1973 Pulitzer Prize-winning book, The Denial of Death. Becker’s thesis was simple: humans are unique because we are aware that we exist, which means we are also aware that we will one day cease to exist. This creates a massive internal conflict. Our biological instinct is to survive, but our intellect tells us survival is impossible.
How do we solve this? We create "cultural worldviews." These are shared sets of beliefs that give life meaning, order, and a sense of permanence. If you belong to a culture that will outlive you, and you contribute something meaningful to that culture, you achieve a kind of "symbolic immortality." You aren't just a meat sack. You’re a "Doctor," a "Patriot," a "Mother," or an "Artist." These labels protect us. They are our armor against the worm.
The Famous "Judge Study" and Why It Matters
You might think this is just abstract psychology. It’s not. There have been over 500 empirical studies on TMT.
One of the most famous ones involved municipal court judges in Arizona. Researchers split the judges into two groups. The first group was given a questionnaire that subtly reminded them of their own death—it asked them to describe what they thought would happen to their bodies when they died. This is called Mortality Salience. The second group (the control) got a neutral task.
Then, both groups were asked to set a bond for a hypothetical prostitute.
The results were wild. The judges who hadn't been thinking about death set a bond of about $50. The judges who were reminded of their mortality? They set it at $455.
Why? Because when we are reminded of death, we cling more fiercely to our cultural worldviews. We want to uphold the "moral order." We become more punitive toward people who violate our shared values and more defensive of our "in-group." It’s a gut reaction. Death makes us more tribal.
The Worm at the Core in Our Daily Lives
You see this everywhere once you start looking. Ever wonder why people get so incredibly angry about sports teams or political flags? It’s rarely about the game or the policy. It’s about the fact that those symbols provide a sense of belonging to something bigger than the self.
When that "something bigger" is threatened, it feels like a personal death sentence.
- Consumerism: We buy things to bolster our self-esteem. High self-esteem acts as a literal psychological buffer against death anxiety. If I have the "right" shoes or the "right" house, I feel like a valuable contributor to society. I feel significant. Significance is the opposite of being dust.
- Aggression: TMT explains why we hate people who have different religions or political views. If your worldview is right, mine might be wrong. And if my worldview is wrong, it can't protect me from the terror of death. Therefore, I must prove you wrong—or, in extreme cases, eliminate you.
- Health Behaviors: Ironically, reminding people of death can sometimes make them engage in unhealthy behaviors if those behaviors are tied to their self-esteem. If a young man thinks smoking makes him look "cool" and "rebellious" (bolstering his ego), a "Smoking Kills" warning might actually make him smoke more to manage the anxiety triggered by the warning.
The Paradox of Self-Esteem
Most people think self-esteem is just about feeling good. In the context of the worm at the core, self-esteem is a survival mechanism. It is the metric by which we measure how well we are living up to our cultural standards.
If you have high self-esteem, you feel like you are a person of value in a world of meaning. You are "immortal" through your works, your children, or your reputation. When self-esteem drops, death anxiety spikes. This is why social rejection feels so much like physical pain. It’s a reminder that we are alone, and being alone in nature usually means you're about to become something's lunch.
Can We Ever Get Rid of the Worm?
Probably not. It’s part of the hardware. However, understanding that our behaviors are driven by this hidden fear can change how we interact with the world.
Researchers like Sheldon Solomon suggest that we can cultivate a more "fluid" worldview. Instead of clinging to rigid dogmas that require us to hate "the other," we can find meaning in more universal human experiences.
There's also evidence that "death reflection"—contemplating death in a calm, philosophical way rather than being jolted by a sudden reminder—can actually make people more compassionate and less tribal. It’s the difference between a panic attack and a "memento mori" practice. One makes you build a wall; the other might make you hug your kids.
Misconceptions About the Theory
A common critique of the worm at the core idea is that people don't spend their whole day thinking about dying. And that’s exactly the point. The theory argues that we have become so good at "managing" the terror that we’ve built an entire civilization as a distraction.
Another misconception is that this only applies to religious people. It doesn't. Atheists use "secular immortality" projects—science, art, fame, or even just being a "good person"—to achieve the same psychological result. The "soul" is replaced by "legacy."
Dealing With the Reality: Actionable Steps
Since you can't escape the worm, the goal is to make sure it isn't driving your car into a ditch. Here is how to handle the existential undercurrent of life:
1. Audit your "Immortality Projects"
Take a look at what you spend your time on. Are you working 80 hours a week because you love the work, or because you’re terrified of being "nobody"? Understanding that your drive for status is often just a defense mechanism can help you reclaim your time.
2. Recognize Mortality Salience in the News
Media outlets thrive on death. Every "breaking news" alert about a tragedy or a threat triggers your subconscious death anxiety. This makes you more likely to seek out "in-group" comfort and become more polarized. When you feel that surge of tribal anger, ask yourself: "Am I actually mad, or am I just feeling vulnerable?"
3. Build Self-Esteem on Internal Values
If your self-esteem is tied to external cultural markers (like money or looks), it is fragile. When those things fade—as they will with age—the "worm" returns with a vengeance. Building self-esteem around internal qualities like kindness, curiosity, or resilience provides a much more stable buffer.
4. Practice "Memento Mori"
Don't wait for a health scare to think about the end. Reflecting on the fact that your time is limited can actually strip away the trivialities. It forces a "triage" of your life. What actually matters? Usually, it's the stuff that doesn't involve buying things or winning arguments.

The worm at the core isn't something to be "cured." It’s the price of admission for being a self-aware human being. But once you see the strings being pulled by that ancient fear, you can start to choose which dance you want to perform. Life is short; it's better to spend it doing things that are actually meaningful rather than just building bigger and better distractions from the inevitable.
