Trust is the bedrock of any successful relationship, whether personal or professional. In organizational life, it’s arguably the most critical element – leaders demand to trust their teams, and employees need to feel confident in their leadership. When a circle of trust is established, collaboration flourishes, innovation thrives, and goals are more readily achieved. But when trust erodes, everything becomes more difficult, progress stalls, and even the most well-intentioned initiatives can falter.

But what does building trust actually *appear* like? It’s more than just stating a commitment to openness and honesty. Recent advances in neuroscience are beginning to shed light on the subconscious cues and behaviors that signal trustworthiness, offering practical insights for anyone looking to strengthen relationships and foster a more trusting environment. Understanding these neurological underpinnings of trust can be a game-changer for leaders and individuals alike.

The science reveals that our brains make snap judgments about trustworthiness – often within the first half-second of encountering someone. But beyond initial impressions, specific behaviors can actively cultivate trust. Here’s a look at five neuroscience-backed strategies for building stronger connections.

The Power of Expressive Faces

Research indicates that we perceive faces displaying a range of emotions as more trustworthy. A study highlighted that expressive faces, those that readily reveal feelings, are more likely to inspire confidence. (Harvard Business Review) This likely stems from a sense of familiarity and the ability to anticipate how someone might react in various situations. When You can “read” someone’s face, we feel more secure in our interactions with them.

Sharing Vulnerability: The Trust-Building Power of Secrets

Counterintuitively, sharing personal secrets can actually *increase* trust. A 2023 study found that when individuals reveal vulnerabilities, others respond with increased liking and trust. (LinkedIn) The act of sharing reduces the burden of keeping secrets and fosters a sense of connection. It signals authenticity and a willingness to be seen as a whole person, not just a professional persona.

The “Mona Lisa Smile” Effect

A subtle smile, reminiscent of the Mona Lisa, can go a long way in building rapport. Research dating back to 2015 demonstrates that a slight, genuine smile is more effective at conveying trustworthiness than a broad grin. (Great Place to Work) This suggests that authenticity and approachability are key – a forced or overly enthusiastic smile can come across as insincere.

Speaking the Same “Language”

Trust is often strengthened by a sense of shared identity. Neuroscience suggests that even subtle linguistic similarities can contribute to this feeling. The way we utilize language – our vocabulary, phrasing, and even regional dialects – can signal belonging and create a sense of “us.” Using similar language patterns as those around you can subconsciously foster trust, as it indicates a shared background or worldview.

The Unexpected Strength of Humility

Finally, and perhaps most surprisingly, humility can be a powerful trust-building tool. A recent study focusing on scientists found that acknowledging limitations and demonstrating intellectual humility increased perceptions of trustworthiness. (CCL) This principle likely extends beyond the scientific community; admitting you don’t have all the answers can make you appear more genuine and relatable.

Putting it all together, the profile of someone we’re likely to trust emerges: an individual who is emotionally expressive, willing to share vulnerabilities, offers a warm but not overwhelming smile, communicates in a way that resonates with others, and isn’t afraid to admit their limitations.

Of course, attempting to consciously implement all of these behaviors at once could come across as contrived. The key is authenticity. These aren’t tricks to manipulate others, but rather insights into the subconscious cues that naturally foster connection and trust.

As organizations navigate increasingly complex challenges, building and maintaining trust will be more critical than ever. By understanding the neuroscience of trust, leaders and individuals can cultivate stronger relationships, foster more collaborative environments, and unlock the full potential of their teams.

A rare and often overlooked condition known as platypnea-orthodeoxia syndrome (POS) presents a unique diagnostic challenge for physicians. Characterized by shortness of breath (dyspnea) that worsens when sitting or standing – platypnea – and a corresponding drop in blood oxygen levels (hypoxemia), POS can be subtle and easily misattributed to other, more common respiratory or cardiac issues. Recognizing the key indicators of this syndrome is crucial for timely diagnosis and appropriate management.

The core of POS lies in an abnormal right-to-left shunting of blood, meaning blood bypasses the lungs and doesn’t obtain properly oxygenated. This can occur due to a variety of underlying anatomical or functional abnormalities. While relatively uncommon, increased awareness of POS is growing within the medical community, leading to more frequent identification, particularly when clinicians consider it in patients with unexplained positional hypoxia. The syndrome is often revealed when a patient presents with positional dyspnea, a symptom that can significantly impact quality of life.

Understanding the Positional Component

The defining feature of platypnea-orthodeoxia syndrome is the positional nature of the symptoms. Patients typically experience relief from their breathing difficulties when lying down. This seemingly paradoxical response is a critical clue. The shift in blood flow dynamics due to gravity plays a significant role. When upright, blood may preferentially flow through abnormal pathways, bypassing the lungs. A case report published in December 2025 highlighted how POS revealed an undiagnosed patent foramen ovale (PFO) in a patient in Cureus.

Several anatomical factors can contribute to this right-to-left shunting. These include a patent foramen ovale (PFO) – a hole between the heart’s upper chambers that didn’t close after birth – atrial septal defects (ASDs), and pulmonary vascular abnormalities. In some cases, POS can be associated with conditions that create an intra-cardiac right-to-left shunt, or even extracardiac causes like pleuro-pulmonary fistulas. A study published in August 2025 in Cureus detailed POS stemming from atrial septal defects, emphasizing the rarity and diagnostic challenges.

Diagnostic Approaches and Key Indicators

Diagnosing POS requires a high index of suspicion and a systematic approach. A thorough patient history, focusing on positional symptoms, is paramount. Clinicians should specifically inquire about whether breathing difficulties worsen upon standing or sitting and improve with recumbency. Physical examination may reveal subtle clues, but often, specialized testing is necessary.

Echocardiography, particularly a bubble study, is a key diagnostic tool. This involves injecting agitated saline into a vein and observing for bubbles crossing into the systemic circulation, indicating a right-to-left shunt. Pulse oximetry, measuring blood oxygen saturation, should be performed in both supine and upright positions to document the desaturation characteristic of POS. Cardiac catheterization may be needed in some cases to further evaluate the anatomy and hemodynamics of the heart. A clinical case study from October 2024 published in Cureus illustrates the diagnostic process and highlights the importance of considering POS in patients with unexplained dyspnea.

The Spectrum of POS and Ongoing Research

It’s important to note that POS isn’t a single, uniform condition. The underlying cause and severity can vary significantly. Some patients may have mild symptoms that are easily managed, while others experience significant limitations in their daily activities. The syndrome was described as an uncommon condition of positional dyspnea and hypoxemia, triggered by standing and relieved with recumbency in a 2023 Cureus report.

Ongoing research continues to refine our understanding of POS, exploring the optimal diagnostic strategies and treatment options. While there is no single “cure” for POS, management focuses on addressing the underlying cause, such as closing a PFO with a percutaneous device, or managing pulmonary hypertension. Further investigation is needed to identify all the contributing factors and develop more targeted therapies.

As awareness of platypnea-orthodeoxia syndrome grows, clinicians are better equipped to recognize this challenging condition and provide appropriate care for affected individuals. Continued vigilance and a thorough diagnostic approach are essential for improving outcomes and enhancing the quality of life for those living with POS.
