Key takeaways
- Emotion is integral to decision-making; people with impaired emotional processing often struggle to make even simple choices.
- Feelings act as fast signals about value and risk, which helps in familiar situations and misleads in unfamiliar ones.
- Incidental emotions, such as stress or mood from unrelated events, can distort decisions without people noticing.
- Leaders and designers can account for emotion through timing, framing, structured reflection and environments that reduce unnecessary stress.
Rethinking the role of emotion in decisions
For much of intellectual history, emotion and reason were treated as opponents. Good decisions, the thinking went, came from calm analysis, and feelings were noise to be suppressed. Research over recent decades has overturned that view. The relationship between emotion and decision-making is not a contest but a partnership. Emotions help people notice what matters, assign value to options and act when information is incomplete, which describes most real decisions. Without them, people can analyze endlessly yet struggle to choose. Understanding this partnership is useful for anyone who makes decisions under uncertainty or designs choices for others, from executives and investors to clinicians, product teams and public health communicators.
This does not mean feelings are always right. Emotions evolved to help people respond quickly to recurring situations, and they can be badly calibrated for modern ones. Anxiety can magnify a small risk; excitement can hide a large one. The goal is not to remove emotion from decisions, which is impossible, but to understand which emotional signals are informative and which are distortions. Leaders who grasp this can make better decisions themselves, create conditions for better decisions in their teams and design products, services and messages that respect how customers and patients actually choose.
The somatic marker hypothesis
One of the most influential accounts of emotion and decision-making comes from neuroscientist Antonio Damasio. Studying patients with damage to parts of the prefrontal cortex involved in processing emotion, he observed that many retained their intelligence and reasoning abilities yet made poor personal and professional decisions. Some struggled to make simple choices at all, weighing options endlessly. Damasio proposed the somatic marker hypothesis: through experience, people learn to associate situations and options with bodily feelings, such as unease or attraction. These markers act as rapid signals that narrow the field of options and guide choice before conscious analysis is complete. When the markers are missing, decision-making becomes slow, unanchored and often unwise.
The hypothesis has been debated and refined, and not every detail has held up, but its central insight is widely accepted: emotional signals are part of the machinery of judgment, not an interference with it. This connects to research on expert intuition, where experienced professionals report a feeling that something is wrong before they can explain why. Those feelings often encode real patterns learned through experience. The implication for leaders is to treat gut feelings as data, worth noticing and examining, rather than either obeying them blindly or dismissing them as irrational.
When emotions help and when they mislead
Emotions are most helpful when they are integral to the decision, meaning they arise from the situation itself and reflect relevant experience. Unease about a deal that seems too good, or confidence about a familiar operational call, can carry genuine information. Emotions are most misleading when they are incidental, arising from something unrelated to the decision. Research shows that mood from an unrelated event, fatigue, stress or even the weather can shift risk tolerance and judgments without people realizing it. Several patterns are worth recognizing, because each suggests a specific safeguard that individuals and teams can adopt.
- Affect heuristic: people judge risks and benefits by how an option makes them feel overall.
- Loss aversion: the pain of losing tends to outweigh the pleasure of an equivalent gain.
- Stress narrowing: acute stress shrinks attention and pushes people toward habitual responses.
- Mood carryover: emotions from one situation spill into unrelated decisions that follow.
- Projection: people underestimate how differently they will feel in a future emotional state.
Emotion and decision-making in organizations
Inside organizations, emotion shapes decisions at every level. Executives under pressure may become more risk averse or more impulsive, depending on temperament and context. Teams in a climate of fear tend to suppress bad news, so leaders decide with incomplete information. Anxiety around a reorganization can make people resist changes they would otherwise support. Leaders can account for this by building routines that create space between feeling and action: pausing before major decisions, separating the meeting where options are generated from the meeting where they are chosen, asking how a decision would look from a calmer vantage point and inviting dissent explicitly. These practices do not remove emotion. They let it inform rather than dominate.
Outside organizations, emotion and decision-making shape how customers, patients and community members respond. A patient anxious about a diagnosis may struggle to absorb treatment instructions, however clear. A borrower stressed about finances may avoid opening statements that would help them. A customer excited about a purchase may overlook terms they will later regret. Designing for these realities means timing information for moments when people can use it, reducing unnecessary stress in processes and interfaces, framing choices honestly and offering support at emotionally difficult points. Ethical design works with emotion to help people act on their own considered goals, never to exploit moments of vulnerability.
How Datalidy applies emotion and decision-making research
Datalidy's foundation in clinical and health psychology and behavioral medicine shapes how we approach emotion and decision-making. With leaders, we use executive coaching to help them recognize their own emotional patterns under pressure and build routines that keep judgment sound. With teams, we design decision processes that surface dissent and reduce the distortions of stress and fear. In customer, patient and member experiences, we map the emotional journey alongside the behavioral one, identify the moments where anxiety, confusion or overconfidence derail good choices, and design and test changes that help people decide in their own interest. Throughout, we treat emotional signals as data worth understanding rather than noise to be ignored.
Frequently asked questions
Do emotions make decisions worse?
Not necessarily. Emotions are an essential part of how people evaluate options and act under uncertainty. People with impaired emotional processing often struggle to decide at all. Emotions become a problem when they are incidental to the decision, such as stress from an unrelated event, or when they are poorly calibrated to an unfamiliar situation. The aim is to understand emotional signals, not to eliminate them.
What is the somatic marker hypothesis?
The somatic marker hypothesis, proposed by neuroscientist Antonio Damasio, suggests that people learn to associate situations and options with bodily feelings through experience. These feelings, or markers, act as fast signals that guide choices before conscious reasoning is complete. The idea emerged from studies of patients whose emotional processing was impaired and who, despite intact reasoning, often made poor decisions in their personal and professional lives.
How can leaders manage emotion in high-stakes decisions?
Build routines that create space between feeling and action. Pause before irreversible choices, separate option generation from selection, invite dissent explicitly and ask how the decision would look under calmer conditions. Notice incidental stress or fatigue and, where possible, avoid making major decisions in those states. Coaching can help leaders recognize their personal patterns and develop habits that keep emotional signals informative rather than overwhelming.
