Do Leaders Who ‘Listen To Their Heart’ May Make More Ethical Choices?

Recent research by Gu et al. (2024) reveals that our physiological state particularly our heart rate can influence our moral decision-making. In two experiments, students who believed their heart was racing were more likely to volunteer for a cause and less likely to lie for personal gain than those who thought their heart rate was normal. The researchers suggest that an increased heart rate signals stress, which prompts individuals to adhere to moral and ethical standards as a way to regulate their emotions.

Interestingly, individuals with higher mindfulness were unaffected by this false heart rate feedback, as were those who were told to view a financial decision-making task analytically rather than intuitively. This finding suggests that while physiological responses influence decision-making, factors such as mindset and emotional awareness can moderate their effects.

The Link to Leadership and the Workplace

For leaders, this research highlights the connection between physiological awareness, ethical leadership, and decision-making under pressure. Stress is a constant in leadership, but how leaders interpret and respond to it can impact their moral and ethical choices.

Leaders who unconsciously allow stress to dictate their actions may become more reactive, whereas those who regulate their emotional and physiological responses can make more balanced, inclusive, and ethical decisions. This is particularly relevant in high-pressure situations—whether dealing with workplace conflicts, making hiring decisions, or addressing performance concerns.

Moreover, the study reinforces the importance of mindfulness in leadership. Leaders who can recognise their emotional and physical states without reacting impulsively are more likely to make decisions aligned with long-term organisational values, rather than short-term stress responses.

Practical Strategies for Leaders and Organisations

To apply these insights in the workplace, leaders and organisations can adopt the following strategies:

1. Develop Emotional and Physiological Awareness

Leaders can benefit from developing a stronger awareness of their physiological responses to stress. Simple practices such as self-check-ins before making key decisions can help regulate emotional and ethical responses. Questions like:

• “Am I making this decision because I feel pressure, or because it aligns with our values?”

• “Is my physical response (e.g., stress, urgency) affecting my judgment?”

2. Integrate Mindfulness Practices into Leadership

Since mindfulness reduces susceptibility to physiological manipulation, incorporating mindfulness practices into leadership development can help leaders regulate their decision-making. Encouraging brief moments of reflection, deep breathing exercises, or mindfulness-based leadership programmes can enhance ethical awareness.

3. Reframe High-Stakes Decisions as Thoughtful, Not Reactive

The study showed that framing a task as a “decision-making” exercise rather than an “intuitive” one reduced the influence of heart rate manipulation. Leaders can apply this by consciously shifting their perspective in moments of pressure. Rather than rushing into a decision, they can pause, gather information, and remind themselves that thoughtful analysis leads to better outcomes.

4. Create a Culture That Supports Ethical Decision-Making

Organisations can help leaders make better moral decisions by embedding ethical reflection into their culture. This includes:

• Normalising open discussions around decision-making processes.

• Encouraging leaders to consult others before making high-impact decisions.

• Providing training on unconscious bias and emotional intelligence to help leaders navigate stress and moral dilemmas more effectively.

This research underscores the intricate relationship between physiology, stress, and ethical decision-making. Leaders who understand their emotional and physical responses can make more ethical, inclusive, and high-performing decisions. By cultivating mindfulness, reframing decision-making, and fostering a culture of ethical leadership, organisations can ensure that their leaders make choices that benefit both people and performance.
