In this episode of Modern Wisdom, Nir Eyal discusses how belief systems shape our perceptions and experiences of reality. He examines how different people can interpret the same information in vastly different ways, and explains the relationship between religious practices and psychological well-being—noting that participating in religious rituals can benefit both believers and non-believers.
Eyal explores the concept that beliefs are not fixed facts but tools that can be updated or discarded based on their usefulness. He delves into the neuroscience of agency and control, suggesting that while helplessness might be our default state, developing an internal locus of control leads to better psychological outcomes. The discussion includes practical approaches to building agency through small, committed steps and setting appropriate checkpoints for personal growth.

Nir Eyal explores how our belief systems fundamentally shape how we perceive and interact with the world around us. Through various examples, including the Koffler illusion, he demonstrates that our brains interpret reality through the lens of our beliefs, with optimists and pessimists literally seeing the same information differently.
Eyal discusses how religious practices can benefit both believers and non-believers alike. He notes that prayer and religious rituals can improve psychological well-being, longevity, and social connections, even for those who don't hold supernatural beliefs. Interestingly, he points out that in Japan, where many people are "religious but not spiritual," participating in religious rituals still provides mental health benefits.
According to Eyal, beliefs are not fixed facts but rather convictions that can be revised based on new evidence. He suggests viewing beliefs as tools that can be picked up or discarded based on their usefulness. Through personal examples, including changing his perspective about his mother's behavior, Eyal demonstrates how challenging and updating limiting beliefs can lead to personal growth and improved relationships.
Recent findings suggest that helplessness might be our default state, rather than learned behavior. Eyal explains that having an internal locus of control—believing you have control over your life outcomes—leads to better psychological outcomes and improved ability to handle adversity. He recommends cultivating agency through small, committed steps and setting "checkpoints" rather than deadlines. This approach, he suggests, helps build what Seligman calls the "hope circuit" in the brain, gradually expanding one's sense of what's possible.
1-Page Summary
Nir Eyal discusses the profound impacts of belief systems on perception, emotions, and behaviors, demonstrating the role they play as a lens through which we interpret the world around us.
Nir Eyal emphasizes that our beliefs are constructs that alter how we perceive reality and others. He gives the example of the Koffler illusion, showing that the same image can be perceived as circles or rectangles based on prior beliefs. He also discusses that because the brain can only process a small fraction of the information it absorbs, it fills in with expectations based on previous experiences and beliefs.
Furthermore, a study showed that optimists noticed helpful information more quickly than pessimists, who tended to ignore it entirely. And Eyal mentions that individuals' diets or fears can lead them to see food as larger or distances as farther away.
Nir Eyal suggests that beliefs can alter not only our external perception but also our internal state. He used personal anecdotes and studies to demonstrate this point. For example, he changed his beliefs on his mother's behavior, altering his emotional response, and managed to overcome neuroplastic pain by convincing his brain he was safe. He also changed his beliefs about sleep which, in turn, reduced his anxiety.
Eyal discusses how placebos can work even when people know they are taking a placebo. He references Ted Kaptchuk's study with IBS patients who were informed they were taking placebos, yet it worked as well as the leading medication. People who received placebo pills even contacted the doctor to request more, indicating noticeable improvement.
Furthermore, Eyal recounts the case of Mr. A, who ingested placebo pills but experienced physiological symptoms of an overdose which reversed after he learned the pills were inert, exemplifying the power of beliefs and expectations on physiological experiences.
Power of Beliefs to Shape Perception and Experience
Nir Eyal discusses the intersection between spiritual and religious practices and their psychological benefits, which have prompted even secular individuals to adopt certain rituals for their secular value.
Eyal emphasizes that prayer and other religious practices can have tangible benefits on psychological well-being, often leading to a longer, healthier, and happier life, as well as a lower incidence of depression and anxiety. Surprisingly, these benefits do not require faith in the supernatural.
Eyal presents evidence that even non-religious individuals can reap the benefits of prayer, as shown in an experiment where non-religious participants who used meaningful words experienced higher pain tolerance, similar to religious individuals. Drawing from personal experience, Eyal engages in secular prayer, using it as a time for gratitude and reflection, and notes the social benefits of religious services, where community connections can provide practical support in personal or business areas. He further points out that participating in community rituals brings psychological and social advantages even to those who do not wholly subscribe to the beliefs.
Eyal also mentions the practice of stepping into open religious institutions, regardless of personal or congregational membership, suggesting one can find benefit in these practices without full adherence to their spiritual aspects.

Beliefs in Spiritual/Religious Practices and Secular Uses
Nir Eyal explores the concept of "limiting beliefs" and suggests strategies for revising and choosing beliefs to foster personal growth and overcome constraints on motivation and potential.
Eyal emphasizes that beliefs are convictions that are open to change based on new evidence, noting that they significantly shape our perception and actions. He endorses the idea that you can choose your beliefs, as they are not facts but convictions that can be revised based on evidence.
Eyal discusses "limiting beliefs," which he describes as deeply held convictions that hold us back from achieving our potential. Often carrying these beliefs around as if they are absolute truths, Eyal argues that in reality, most are not facts but rather constructions that can guide or misguide our lives. Eyal encourages people to examine these beliefs through reflection and interaction with new evidence, to address whether they are beneficial or harmful.
Eyal shares a personal experience regarding his initial belief about his mother's judgmental nature and how it affected his actions. Through self-examination, he questioned the accuracy of this belief and considered how he might feel without it. By entertaining new beliefs and evidence, he unlocked alternative pathways to happiness that did not depend on his mother's actions, illustrating how challenging limiting beliefs can lead to personal growth.
Eyal proposes that beliefs should be viewed as discardable tools—used when beneficial and set aside when they no longer serve our growth. Likening beliefs to a carpenter's tools, Eyal suggests we should choose beliefs that align with our goals and discard those that are not needed. To demonstrate this, Eyal conducted an experiment, adopting a new belief for a week to see how it affected his life, demonstrating that beliefs can be tried on and discarded if they prove unhelpful or untrue.
Eyal also addresses broader implications of be ...
Updating and Choosing Limiting Beliefs
The neuroscience of how individuals perceive agency and control, as opposed to feelings of helplessness, has important implications for psychological well-being and the ability to overcome adversity.
An internal locus of control, the belief that you have control over your life and outcomes, is beneficial psychologically. This belief is linked to better outcomes in adversity, such as living longer, having more friends, contributing more to the community, and experiencing higher levels of well-being with fewer mental health issues. Eyal interviewed David Fajenbaum, who exemplified this by taking action to research his incurable disease, ultimately discovering a life-saving medication.
Understanding the difference between pain and suffering can cultivate an internal locus of control. For example, Eyal's personal story of alleviating pain by repeatedly assuring his brain "I'm safe" demonstrates the empowering effects of internal locus of control in overcoming insomnia and adversity.
Recent findings suggest the original theory of learned helplessness, the idea that hope is taught and helplessness is learned, may be incorrect. Instead, helplessness may be our default state, and hope and a sense of agency must be taught.
To combat feelings of helplessness, Eyal suggests setting “checkpoints” rather than deadlines and enduring discomfort without interpreting pain as suffering too quickly. Small, ...
