In a recent LinkedIn post, Shannonsmithjdms explores the profound connection between our nervous system and our capacity for openness, challenging the common perception of openness as merely a mindset. Shannonsmithjdms posits that true openness is, in fact, a physiological state, deeply rooted in how our nervous system responds to perceived risks and uncertainties.

The post highlights a common paradox: individuals often believe they are open to new information, yet their brains may be actively resisting it. Shannonsmithjdms describes this internal conflict, stating:

“Most people think they’re being open while their brain is quietly rejecting information. Scanning for flaws. Defending past choices. Looking for what confirms their view.”

The Brain’s Default to Certainty

Shannonsmithjdms argues that the brain naturally categorizes uncertainty as a risk, prompting a defensive posture. This leads to a tightening of control within the nervous system, which in turn narrows attention and filters perception. Anything unfamiliar can be flagged as suspect, as the brain prioritizes maintaining internal coherence over embracing growth. This protective mechanism, according to Shannonsmithjdms, is particularly evident in environments that reward being definitively ‘right’ rather than encouraging exploration.

Receptivity Through Physiological Regulation

The key to genuine expansion and learning, Shannonsmithjdms explains, lies in receptivity, which is unlocked when the parasympathetic nervous system is activated. This state is characterized by physical relaxation, deeper breathing, and a loosening of mental rigidity. Shannonsmithjdms elaborates on this physiological shift:

“When the parasympathetic nervous system activates, the body softens. Muscles relax. Breath lengthens. Mental rigidity loosens. In that state, the brain widens its aperture instead of narrowing it.”

In this receptive state, the brain becomes capable of holding multiple perspectives simultaneously, exploring contradictions, and forming new mental models. Shannonsmithjdms emphasizes that this isn’t about immediate agreement but about creating the conditions for consideration. This is where psychological safety becomes paramount.

The Importance of Psychological Safety

According to Shannonsmithjdms, psychological safety signals to the brain that one’s status is not threatened, that updating beliefs will not lead to punishment, and that curiosity is permitted. This safety allows the brain to move from filtering information to integrating it. Shannonsmithjdms makes a direct link between this process and progress:

“Without safety, the brain filters. With safety, the brain integrates. No receptivity, no learning. No learning, no innovation.”

Practical Steps to Cultivate Openness

Shannonsmithjdms offers actionable advice for increasing openness, focusing on regulating the nervous system and fostering a more receptive state:

  1. Slow the physiological response: Shannonsmithjdms suggests that calm bodies are better equipped to tolerate ambiguity, and openness follows physiological regulation.
  2. Name defensiveness: By recognizing and naming defensiveness as it arises, individuals can reduce automatic rejection and regain a sense of choice.
  3. Deliberately expose yourself to difference: Shannonsmithjdms recommends seeking out novel inputs to stretch cognitive maps, asserting that growth requires contrast.

In conclusion, Shannonsmithjdms reframes being open-minded not as a matter of simply agreeing with new ideas, but as providing the brain with the necessary safety and space to adapt and learn. The post effectively argues that true openness is a cultivated nervous system state, essential for personal and professional growth.
