Beyond Mindset: Shannon Smith, J.D., M.S. Explains How Nervous System States Drive Openness

In a recent LinkedIn post, Shannon Smith, J.D., M.S. challenges the conventional understanding of “openness,” arguing that it is not merely a mindset but a fundamental state of the nervous system. Smith, J.D., M.S. posits that many individuals believe they are open to new information, while their brains are in fact actively resisting it by scanning for flaws, defending past decisions, or seeking confirmation of existing beliefs.

The core of Smith, J.D., M.S.’s argument centers on the brain’s natural inclination to perceive uncertainty as risk. This leads to a physiological bracing response, a tightening of control that inevitably narrows attention and filters perception. “The brain treats uncertainty like risk. So it braces,” Shannon Smith, J.D., M.S. writes in the post. This protective mechanism, while essential for maintaining coherence, can inadvertently stifle personal and professional growth, particularly in environments that prioritize being “right” over embracing new perspectives.

The Biological Basis of Receptivity

Shannon Smith, J.D., M.S. elaborates on how true expansion and learning hinge on receptivity, a state intrinsically linked to the activation of the parasympathetic nervous system. When this system is engaged, the body naturally softens, muscles relax, and breathing deepens. This physiological shift, according to Smith, J.D., M.S., allows the brain to widen its aperture, moving beyond rigid adherence to existing viewpoints.

“When certainty feels necessary, the nervous system tightens control. Attention becomes selective. Perception gets filtered. Anything unfamiliar feels suspect,” Shannon Smith, J.D., M.S. explains. This contrasts sharply with the state of receptivity, where the brain can entertain multiple perspectives, explore contradictions, and begin forming new mental models. The crucial enabler for this process, Smith, J.D., M.S. highlights, is psychological safety.

Psychological Safety as a Catalyst for Integration

According to Shannon Smith, J.D., M.S., psychological safety signals to the brain that one’s status is not at risk and that updating one’s beliefs will not lead to punishment. This environment allows curiosity to flourish, transforming the brain’s function from filtering information to integrating it. “Without safety, the brain filters. With safety, the brain integrates. No receptivity, no learning. No learning, no innovation,” states Shannon Smith, J.D., M.S.

Practical Strategies for Cultivating Openness

To foster greater openness, Shannon Smith, J.D., M.S. proposes three actionable strategies:

1. Slow the physiological response: Smith, J.D., M.S. emphasizes that calm bodies are better equipped to tolerate ambiguity, suggesting that openness is a byproduct of nervous system regulation.
2. Name defensiveness: By becoming aware of and naming defensive reactions as they arise, individuals can reduce automatic rejection and regain a sense of choice.
3. Deliberately expose yourself to difference: Shannon Smith, J.D., M.S. advocates for seeking out novel inputs, arguing that these contrastive experiences stretch cognitive maps and are essential for growth.

Ultimately, Shannon Smith, J.D., M.S. concludes that being open-minded is less about immediate agreement and more about providing the brain with the necessary safety and space to update its understanding.
