Most people assume that belief change is a rational process. If new information is credible, well supported, and clearly contradicts an existing belief, then updating one’s position should follow naturally. In practice, this is rarely how belief change occurs.
Across clinical work, organizational settings, family systems, and public discourse, it is common to see people maintain positions even when presented with strong counterevidence. This does not reflect stubbornness, lack of intelligence, or bad faith. It reflects how the human brain organizes, protects, and stabilizes meaning.
Understanding why belief change is difficult requires examining how beliefs function psychologically, not just logically.
Beliefs are often treated as discrete opinions that can be swapped out when better data becomes available. In reality, beliefs exist within broader cognitive and emotional systems. They are shaped by identity, history, relationships, culture, and prior learning.
A single belief is rarely standing alone. It is typically connected to:
• A sense of self or moral identity
• Belonging to a group or community
• Emotional memories and past experiences
• Assumptions about safety, threat, or predictability
When a belief is challenged, the brain does not interpret this as a neutral intellectual exercise. It often interprets it as a potential threat to coherence, stability, or belonging.
One well-established explanation for resistance to belief change is belief perseverance. Belief perseverance refers to the tendency to maintain an initial belief even after the evidence supporting it has been discredited or contradicted (Anderson, 2007). Once a belief is formed, people tend to continue relying on it as a framework for interpreting new information. Even when the original justification is removed, the belief itself often remains intact.
From a psychological perspective, this makes sense. Beliefs serve as organizing principles. They reduce cognitive load by helping us interpret the world efficiently. Letting go of a belief can temporarily increase uncertainty, ambiguity, and emotional discomfort, which the brain is wired to avoid.
Belief perseverance is reinforced by confirmation bias, the tendency to preferentially seek, interpret, and remember information that supports existing beliefs while discounting information that challenges them. Closely related is motivated reasoning, which describes how people unconsciously use reasoning processes to arrive at conclusions they want to be true, rather than those most supported by evidence.
These processes are not deliberate or manipulative. They operate automatically and often outside of conscious awareness. People can genuinely feel that they are being objective while selectively engaging with information that preserves their existing worldview. Importantly, confirmation bias is not limited to any one political, cultural, or educational group. It is a universal feature of human cognition.
Another factor that makes belief change difficult is cognitive dissonance, the psychological discomfort that arises when new information conflicts with existing beliefs, values, or behaviours.
When dissonance occurs, the brain seeks relief. This relief can be achieved in multiple ways:
• Rejecting or minimizing the new information
• Questioning the credibility of the source
• Reinterpreting the information to fit existing beliefs
• Strengthening the original belief
From an emotional regulation standpoint, changing one’s mind can feel destabilizing. It may evoke shame, grief, fear, or a sense of having been wrong in a way that feels personally significant. Avoiding belief change is often less about rejecting facts and more about managing emotional discomfort.
Beliefs do not exist in isolation. They are embedded within larger systems of meaning. Research on belief change increasingly emphasizes that people are not simply updating individual propositions, but navigating entire networks of assumptions, narratives, and values.
Changing one belief may require reconsidering:
• Who I am
• Who I trust
• What I value
• Where I belong
This helps explain why evidence alone is often insufficient to produce change. When a belief is tied to identity or community, changing it may carry perceived relational or existential costs.
Recognizing the psychological complexity of belief change has important implications.
In therapeutic settings, it reinforces the importance of pacing, safety, and curiosity. Clients often need support tolerating uncertainty and emotional discomfort before meaningful cognitive shifts can occur.
In interpersonal and public conversations, it suggests that persuasion is rarely effective when approached as a debate to be won. People are more open to reconsidering beliefs when they feel respected, understood, and emotionally regulated.
Belief change is more likely when:
• People feel psychologically safe
• Their values and identity are not being attacked
• There is space for reflection rather than pressure
• Emotional needs are acknowledged alongside evidence
It is tempting to view resistance to evidence as irrational or willful. A more accurate framing is that belief stability is adaptive. The human brain prioritizes coherence, predictability, and emotional safety. Changing one’s mind is not simply an intellectual act. It is a relational and emotional process that unfolds over time.
Approaching belief differences with humility and curiosity does not mean abandoning critical thinking. It means recognizing that evidence is most effective when it is integrated into contexts that support psychological safety and meaning-making. At VOX Mental Health, we often see that lasting change occurs not when people are forced to confront facts, but when they are supported in understanding the deeper systems that shape how those facts are received.
