Why the Brain Resists Change: The Role of Predictability and Control

Our brains are fundamentally wired to seek predictability. They constantly scan the environment, looking for patterns and trying to anticipate what comes next. This drive for predictability helps us feel safe and conserve mental energy by operating on autopilot for routine tasks. When change occurs, it disrupts these established patterns, plunging us into uncertainty, which the brain perceives as a potential threat.

This sense of threat is amplified when we feel a lack of control over the situation. The brain's threat response system, primarily involving the amygdala, becomes highly active when predictability vanishes and we feel powerless to influence outcomes. This triggers a cascade of physiological and psychological reactions designed to protect us, often manifesting as resistance, anxiety, or withdrawal.
