The Power of Beliefs begins with a question that reaches far beyond positive psychology: how much of what happens next in our lives is influenced by the way we understand the world around us? In my conversation with Shawn Achor, the psychologist and bestselling author, we explore how beliefs shape the possibilities we recognize, the challenges we are willing to face, and the meaning we draw from our experiences. Shawn’s research invites us to look more closely at the assumptions that guide our decisions, particularly the beliefs we hold about our own capabilities, our relationships, and whether our actions make a difference.
Our conversation moves from the science of the placebo effect to the home-field advantage in sports, then into a larger question about the conditions that help people feel connected to something meaningful. Shawn explains why a belief can become more consequential when it is grounded in evidence and translated into action. We also explore his idea of the Great Drift, a growing disconnection from traditional sources of shared belief and belonging, and consider how that disconnection can influence the way people experience work, relationships, and their own worth.
What stayed with me is the connection between belief and mattering. When people begin to believe that they are alone, that their work is insignificant, or that their behavior makes little difference, those assumptions can shape the choices they make and the opportunities they recognize. When people have credible reasons to believe that they can contribute, that others support them, and that their actions have meaning, they have a different foundation from which to meet life’s challenges. Belief does not guarantee an outcome, but it can influence the path we take toward it.
What Is the Power of Belief, and How Does It Shape What Happens Next?
Shawn describes belief as the lens through which we view the world. That lens influences how we interpret a difficult experience, what we expect from a new opportunity, and which actions seem worth taking. Two people can encounter the same setback and reach very different conclusions about what it means. One may interpret it as evidence that further effort is pointless, while another may see a problem that calls for a different strategy, additional support, or more time to develop a skill. Their circumstances may be similar, yet their beliefs can lead them toward different responses.
This is one reason Shawn’s work extends beyond the familiar advice to think positively. The beliefs we carry can influence the relationship between an experience and our response to it. They shape the meaning we assign to events, and that meaning can affect our willingness to engage with what comes next. The important question, then, is how to build beliefs that help us respond constructively while remaining connected to the evidence and realities of our lives.
Why Success Doesn’t Automatically Lead to Happiness
In discussing the ideas behind his earlier work on happiness, Shawn revisits a belief many of us absorb without examining it: if we work hard enough to achieve success, happiness will follow. The problem with this assumption is that it places happiness permanently on the other side of the next milestone. A promotion, a financial target, a completed project, or a long-awaited recognition can become a temporary arrival before attention shifts toward another goal. Achievement may bring genuine satisfaction, yet the belief that happiness must wait until success arrives can make contentment feel perpetually out of reach.
Shawn describes a different relationship between happiness and performance. His work suggests that optimism, social connection, and a sense of meaning can influence how people approach their goals, including when circumstances are difficult. These qualities can change the experience of pursuing success and may support the behaviors that help people make progress. This perspective invites us to examine the assumptions we bring to our ambitions: whether we are building a life that feels meaningful along the way, or postponing that experience until we reach a destination that may keep moving.

Belief Versus Wishful Thinking: Building Confidence on Evidence and Action
A belief becomes more useful when we understand why it is reasonable and what we can do to support it. Shawn explains this through two concepts: a warrant and a qualifier. A warrant provides the “because” behind a belief, drawing on relevant experience, available resources, or evidence that makes a desired outcome plausible. A qualifier adds the conditions and actions that could make the outcome more likely. Together, they give belief a practical foundation.
Consider a child beginning at a new school. Telling that child everything will be wonderful may offer brief reassurance, but the reassurance has little substance if the child cannot see why it should be trusted. A more grounded response might recall how the child formed friendships at a previous school, connected with teammates, and showed kindness to others. It can then identify the actions that could help again, such as joining an activity, introducing themselves to classmates, and giving relationships time to develop. The belief now rests on relevant experience and a path forward.
The same reasoning applies to professional goals, personal growth, and difficult periods of life. Confidence can be connected to skills we are developing, support we can seek, and choices we can make. This approach respects uncertainty while preserving our ability to act. It also reminds us that a belief can still be valuable when the precise outcome we hoped for does not occur, because the effort and decisions it encourages may open other paths along the way.
How Belonging Shapes Performance and the Way We Face Challenges
One of the most striking examples Shawn shares concerns the home-field advantage in sports. Home teams have often enjoyed measurable advantages, and the usual explanation points to familiarity, travel, weather, and the comfort of playing in a known environment. Shawn discusses what happened during the pandemic, when games were held in familiar stadiums without spectators. He describes research suggesting that the usual home-field advantage diminished when the crowds disappeared, drawing attention to the psychological meaning of playing in front of people who appear to support one team or the other.
For Shawn, the example raises a broader question about the belief that we are alone or supported as we face a challenge. A stadium crowd is one visible form of social connection, but the underlying idea also applies to workplaces, classrooms, and communities. When people feel that others recognize their efforts and want them to succeed, they may approach difficult tasks with a different sense of possibility. When they feel isolated or believe the world is working against them, the same challenge can appear much harder to navigate.
This connection between belonging and performance matters because people rarely make decisions in a social vacuum. The relationships around us help shape what we expect, how we interpret feedback, and whether we believe our efforts can make a difference. A supportive environment cannot remove every obstacle, but it can provide the trust and encouragement that help people remain engaged while they work through one.
Explore Shawn Achor’s The Power of Beliefs: A Practical Guide to What Happens Next
While writing The Happiness Advantage, Shawn Achor began questioning an assumption that often guides our ambitions: that success must come first and happiness will follow. As he explored the relationship between positive psychology and performance, he became interested in a broader question about the beliefs through which people interpret their lives. That question eventually led him toward The Power of Beliefs, a book about how beliefs can influence the possibilities people recognize and the paths they pursue.
The book brings together Shawn’s interest in the relationship between belief and experience, including his discussion of the placebo effect, social connection, and human performance. It also considers what happens when people lose their connection to shared sources of meaning and begin to adopt beliefs that they are alone, that their behavior makes little difference, or that their work lacks purpose. Shawn’s central concern is how those beliefs influence what people expect from themselves and the world around them.
One of the most useful aspects of his approach is its emphasis on practical ways to examine and reshape beliefs. Language affects the way we frame our experiences, relationships influence the assumptions we absorb, and memories help provide the evidence from which we construct a view of ourselves. Everyday actions can reinforce these influences by creating experiences that support a more grounded understanding of our capabilities and contribution.
The Power of Beliefs is ultimately an invitation to examine the assumptions that guide our choices and ask what evidence, relationships, and actions could help us build a more constructive path forward. For readers interested in positive psychology, meaningful work, belonging, and the psychology of success, it offers a framework for thinking about belief as something that develops through the ongoing relationship between our inner lives and the world we inhabit.
The Great Drift: Why Meaning, Belonging, and Mattering Matter
Shawn uses the term the Great Drift to describe what he sees as a weakening connection to traditional sources of shared beliefs, including villages, workplaces, political structures, and religious communities. These institutions have historically helped many people understand their place in a larger group. As patterns of work, social interaction, and community change, people may have fewer stable points of connection through which to develop shared meaning. Shawn argues that the desire for purpose and belonging remains, even as the structures that once helped provide them become less dependable for many people.
In our conversation, Shawn identifies several beliefs that can become painful organizing assumptions: that our behavior does not matter, that we are alone, that we do not matter, that our work lacks meaning, or that we have nothing to give. These beliefs are significant because they can influence how we interpret daily experience. A missed opportunity may become evidence that we have little to contribute. A period of loneliness may begin to feel like proof that connection is unavailable. When such interpretations go unexamined, they can narrow the range of actions we consider worthwhile.
The alternative begins with experiences that give people credible reasons to see themselves differently. Belonging grows through relationships in which people are known and included. Meaning can emerge when we understand how our work or care contributes to something beyond ourselves. Mattering becomes more tangible when others recognize our efforts and when we can see the effects of our actions. These experiences do not solve every source of disconnection, but they help build a more complete picture of who we are and what our lives make possible.
How to Strengthen Your Beliefs Through Everyday Actions
Shawn discusses several ways beliefs can be shaped, including language, memory, relationships, shared texts, and the actions people observe in one another. These influences matter because beliefs are continually informed by the information we encounter and the experiences we use to understand ourselves. If our attention repeatedly returns to moments of failure or rejection, those memories may dominate our sense of identity. If we make room to recognize meaningful relationships, past contributions, and moments when we handled difficulty well, we can draw on a fuller account of our lives.
One of Shawn’s practical suggestions involves revisiting meaningful positive memories. Looking through photographs or recalling experiences with people who matter can help bring overlooked evidence back into view. Someone who believes they are poor at forming relationships, for example, might discover a history of friendships, shared activities, and small acts of care that complicate that conclusion. The point is not to manufacture a flattering story, but to make sure a painful assumption does not become the only story available.
Language and relationships also influence the beliefs we reinforce. The words we use can shape the questions we ask and the explanations we accept, while the people around us can influence what we consider possible. Small actions create opportunities to test assumptions in the world: reaching out to someone, offering help, asking for feedback, or taking a step toward meaningful work. Over time, these actions can generate new experiences that give us better evidence for understanding ourselves and others.
The work of changing belief therefore involves both reflection and participation. We examine the assumptions guiding our choices, consider what supports them, and take actions that allow us to learn. That process makes room for optimism without requiring certainty. It helps us build a more accurate understanding of our lives while remaining open to possibilities we may not yet have explored.
The Mattering Effect: How Beliefs Connect Us to a Life of Meaning
Throughout this conversation, I kept returning to a question that sits beneath many of the challenges Shawn describes: what happens when people begin to feel that they do not matter? The question reaches into our work, relationships, and communities. It affects how we interpret our contribution and whether we believe there is a place for us in the lives of others. Shawn connects this sense of mattering to meaningful work, explaining that work can include far more than a paid job. Parenting, caring for a partner, serving a community, and supporting others can all provide ways to contribute to something that matters.
The relationship between mattering and belief is especially important because our sense of contribution depends partly on what we learn to notice. Recognition from another person, a thoughtful note, a moment of genuine appreciation, or the visible effect of our effort can become evidence that challenges the assumption that we make little difference. Such moments do not define our worth, but they can help us see the relationships and contributions that a narrowed or discouraged perspective might overlook.
For me, the lasting insight is that a meaningful life is shaped through the relationship between what we believe, how we act, and what our environments make possible. Beliefs can help us recognize opportunities to contribute, while relationships and meaningful actions can provide new evidence about who we are. The work is both personal and shared: we can examine our own assumptions while helping create workplaces, families, and communities where people have real reasons to feel included, valued, and able to make a difference.

FAQ (Frequently Asked Questions)
What is the psychology of belief?
The psychology of belief explores how people form beliefs and how those beliefs influence perception, expectations, decisions, and behavior. Shawn Achor describes beliefs as a lens through which people interpret the world and assess what may be possible. That lens can influence how people respond to challenges and which actions they are willing to take.
How do beliefs affect behavior?
Beliefs can influence what people pay attention to, the goals they pursue, and how they respond when circumstances become difficult. A person who sees a plausible path toward a goal may be more willing to act, seek help, and persist through setbacks. Beliefs do not control every outcome, but they can shape the decisions and behaviors that contribute to what happens next.
What is the difference between belief and wishful thinking?
Wishful thinking focuses on a desired outcome without establishing a credible path toward it. Shawn Achor explains that a more actionable belief includes a warrant, or a reason supported by evidence, and a qualifier, or the actions and conditions that could make the outcome more likely. This approach connects confidence to practical steps while acknowledging uncertainty.
Can changing your beliefs change your life?
Changing a belief can alter how someone interprets an experience, responds to a challenge, or approaches an opportunity. Those changes can influence behavior and open possibilities that previously seemed out of reach. A new belief cannot guarantee a particular result, but examining assumptions and taking purposeful action can help people respond to their circumstances differently.
How does believing you matter affect well-being?
Believing that you matter can influence how you understand your relationships, your contribution, and your place in a community. Shawn connects mattering with belonging and meaningful work, emphasizing the importance of seeing how our actions affect others. Recognition and meaningful experiences can provide evidence that helps people question the assumption that they have little to contribute.
How can you build beliefs that support meaningful work?
Begin by examining what you believe about your contribution and the evidence behind that belief. Look for specific ways your work supports other people or advances a shared purpose, seek relationships that provide constructive feedback, and take actions that let you experience the effects of your efforts. Meaningful work can include paid employment, caregiving, volunteering, and other forms of service.
