Why We Make Assumptions — and How Curiosity Reopens the Mind
The brain loves efficiency.
Assumptions are one of its favorite shortcuts.
When we assume, the brain is trying to conserve energy by filling in gaps with past experiences, patterns, and expectations. The limbic system quickly scans for familiarity and safety, while the brain’s predictive networks say, “I’ve seen this before — I know how this ends.”
Curiosity, on the other hand, requires something different.
It asks the prefrontal cortex to stay online — to pause, gather information, and tolerate uncertainty. That takes more energy, more regulation, and more flexibility than making a snap judgment.
From a brain coaching perspective, people don’t choose assumptions because they’re closed-minded. They choose them because the brain is under stress, overstimulated, or operating on autopilot.
When regulation improves, curiosity becomes accessible again.
Practices that support this shift include:
Neurofeedback to help the brain move out of reactive patterns
Breathwork to slow the nervous system and widen perspective
Intentional pauses that interrupt automatic thinking
Novel experiences that retrain the brain to stay open and engaged
A regulated brain can afford to ask better questions.
It listens longer.
It reacts less.
And it replaces certainty with understanding.
Curiosity isn’t a personality trait —
it’s a brain state.
And when the brain feels safe and supported, curiosity naturally returns.
