Why do people switch worldviews?
On the slow unmaking, and remaking, of beliefs
In this essay, I explore what a worldview is, how it can shift, and what it feels like when that happens. I share a few snapshots from my own experience as one data point among many, and prompt readers to reflect on how their own worldviews evolve over time.
Dissecting beliefs
Recently, I enrolled in a course called Micro-Philosophy: Foundations delivered by Paul Musso. As the name suggests, it's designed to help participants examine and refine their belief system. The first few lessons prompted me to reflect on my own birthviews and other worldviews I hold:
What assumptions have I carried without questioning?
What parts no longer feel aligned with my values?
And just as importantly, what other worldviews, or parts of worldviews, might resonate more deeply now than the ones I inherited?
This essay is an attempt at answering these questions. I hope they can help you reflect, and if you want to dive deeper into the topic, I strongly recommend enrolling in the course!
When a Worldview Starts to Shift
Do you recall a moment when you began to see the world differently, when a familiar set of beliefs started to loosen? Sometimes the shift is gradual. Other times, something gives way all at once. Either way, it can be a deeply unsettling, yet transformative experience. My friends and I like to call this shift an “ontological earthquake”.
According to Paul Musso, a worldview is the mental framework you use to make sense of the world. It influences what you pay attention to, what you care about, and your day-to-day choices. Beneath the surface, it encodes deep assumptions about truth, meaning, values, morality, and reality itself, assumptions we rarely notice or question.
Different people can experience the same event and walk away with entirely different takeaways, because their worldviews filter those facts in different ways. Imagine two people attending the same climate change conference. One has a mental model where technological innovation is the main lever for solving global problems. The other sees structural inequality as the core issue. When they hear the same presentations, the first updates on the feasibility of new tech, while the second notes the absence of equity-focused solutions. Same data, different filters, because their prior beliefs shape what they pay attention to and how they interpret new information.
Culture, language, personal history, and material conditions all play a role in shaping the lenses through which we perceive the world. Most of us navigate life guided by inherited worldviews we didn’t consciously choose. But with reflection and the right tools, we can bring these frameworks into view, and decide whether to keep them, revise them, or build new ones.
Worldview changes can occur for many reasons. They might be sparked by internal tension or external turning points. This list is an attempt to map some of the key forces that can catalyze such shifts. It does not aim to be exhaustive.
One common trigger for worldview change is cognitive dissonance: the psychological tension that arises when your actions don’t align with your beliefs (Festinger, 1957). This signals a mismatch in your mental map: you might care deeply about animal welfare, yet still consume factory-farmed products. Or you might believe in helping others, but continue to live comfortably without contributing. Over time, this dissonance can become too large to ignore. Some people resolve it by updating their values to match their behavior. Others change their behavior to realign with their values.
In The Awakened Brain, psychologist Lisa Miller argues that people operate in two cognitive modes, each based on a different model of how the world works. The Achieving Brain sees life as self-directed, outcomes depend on individual effort, control, and performance. The Awakened Brain, by contrast, assumes life is interconnected. Miller’s research, including fMRI and longitudinal studies, suggests that existential adversity (e.g. grief, depression, loss of direction) can weaken the Achieving Brain’s predictive model, allowing the Awakened mode to emerge. This shift reflects a deeper change in worldview. People in the Awakened Brain report greater purpose, relational depth, and resilience, with less isolation.
Sometimes, this shift is also shaped by community: meeting people who live out values you hadn’t yet imagined were possible, for instance people who steer their time, energy, and money toward acts of service to the world. Haidt’s Moral Foundations Theory (2012) highlights how moral commitments are often embedded in community and culture. We absorb values from those around us. So when we’re exposed to people who live by different foundations, like care, fairness, or sanctity, it can trigger dissonance or curiosity.
Another catalyst for worldview change, as explored in Michael Pollan’s How to Change Your Mind, is the use of psychedelics. These substances, when taken in guided or intentional settings, have been shown to quiet the brain’s default mode network, the system responsible for maintaining the ego and habitual patterns of thought. In doing so, they can dissolve long-held assumptions about the self, death, nature, and consciousness. Many participants in clinical studies report a lasting shift in values and perspective.
Another example I wish to introduce is meditation. The practice of meditation can create the conditions for deep worldview shifts by changing how we relate to the mind. As Robert Wright explains in Why Buddhism Is True, the brain is a collection of modules: systems evolved for tasks like avoiding danger, seeking approval, or pursuing rewards. These modules often trigger automatic thoughts and emotions that feel like “you,” even when they conflict. Mindfulness helps people observe these impulses as mental events rather than truths. This shift, from identification to observation, can loosen rigid beliefs about the self. Over time, it weakens inherited narratives (“I must achieve to be worthy”) and opens space for new worldviews to emerge.
Roots
In my case, the shift came slowly, though the groundwork was laid early.
I grew up with parents whose curiosity knew few boundaries. Their interests zigzagged across disciplines and continents, and so did our dinner conversations. We liked to think we didn’t follow any single ideology. Looking back, it’s clear we were steeped in secular humanism, a belief that reason and empathy, rather than religion, could guide moral life.
My brother and I were raised atheist, though a sense of moral responsibility still threaded through our upbringing. Both of my parents used to work in international development. Postcards from Handicap International and Doctors Without Borders brought distant crises into our home, turning abstract suffering into something tangible.
I don’t want to discard the worldview I grew up with. It gave me tools I still rely on: aiming to think more clearly, to act ethically (whatever that means), to not look away from suffering. Secular humanism taught me to care about people far away, to trust science, and to strive for fairness. But over time, I began to feel the edges of that frame. It offered less guidance on how to sit with uncertainty. It didn’t speak much to spiritual longing. And its focus remained firmly centered on humans.
Revisions
When I encountered Effective Altruism and Longtermism, these ideas gave me new ways of thinking about care and responsibility. Slowly, I began to question the species-bound nature of the framework I’d inherited. I also started taking more seriously how our actions ripple into the future and how the lives of future generations carry moral weight too. And still, there were significant mismatches in my mental map. For example, I cared about animal welfare, but continued to consume animal products for years. It took time, and it still takes effort, to bring my actions into alignment with my values. What helped was a combination of the factors mentioned above: examining my cognitive dissonance, connecting with people who embodied the values I aspired to live by, developing a meditation practice, and nurturing what Lisa Miller calls the “awakened brain.”
Together, these influences made it possible to start integrating a more coherent worldview. That shift led me toward a sentient-centric perspective: one that takes seriously the experiences of all beings capable of joy or suffering, across species and across time. A view that softens the boundaries we draw, between humans and animals, between present and future, and widens the moral circle toward a more inclusive kind of consideration.
Another recent deviation from the secular humanist framework came about when reading the book Religion for Atheists, by Alain de Bottom. His core thesis is that religions are rich repositories of wisdom on how to live well, and we can borrow their structures and practices without needing to accept their supernatural beliefs. This book made me question the extent to which I internalized that as an atheist, I should reject all aspects of religion.
Perhaps it was time for me to start looking into what religions had to offer beyond the mere belief in a deity: cultural technologies that secular society could benefit from.
I recognize that religions can be deeply flawed, and personally do not believe in the supernatural dimension they offer. And yet;
They do a great job at fostering community and belonging through shared rituals and gatherings that create deep social bonds, something I find to be lacking in many modern, atomized lives.
Their use of ritual and repetition, such as prayer, or the spaces they curate through art and architecture, provide room for transcendence.
Religion prompts practitioners to think about practical wisdom for living through moral instruction, countering the fact-based but emotionally detached focus of modern education.
They can also provide consolation in suffering, with time-tested frameworks for navigating grief, loss, and existential uncertainty, territory where secular cultures often fall silent.
Concluding thoughts
Changing your worldview, in my humble opinion, is a good sign. It suggests you’re willing to revise your mental models when they no longer match the data. That you’re led more by curiosity than by attachment to an identity, a role, or a tribe.
Worldview shifts can be disorienting. They certainly were for me. But I have a hunch: they’re part of the path toward a more coherent, meaningful life.
A final prompt to carry with you:
If your worldview has shifted, what sparked the change?
And where might your map still be waiting for an update?
