Planning a holiday should be simple. You pick a destination, book the trip and relax. However, in reality it rarely works that way. Many of us spend hours comparing options, feel unsure about the decisions we make, and return remembering only parts of the experience. This is not just about holidays. It reflects something fundamental about how people think and make decisions. These same patterns are highly relevant to healthcare decision making, where the consequences are far more significant. Why Healthcare Decisions Are Not Always Rational In healthcare, patients and healthcare professionals are expected to make logical and evidence based decisions. However, behavioural science shows that decision making is rarely fully rational. It is shaped by cognitive biases that influence how information is processed, how options are evaluated and how experiences are remembered. Recognising these biases is important for improving patient outcomes and communication. Three key concepts help explain why decision making can be challenging: choice overload, affective forecasting and the peak end rule. Choice Overload and Its Impact on Patients Choice overload happens when having too many options makes it harder to decide. Although we often assume more choice leads to better decisions, it can have the opposite effect. People can feel overwhelmed, which leads to hesitation, delay or dissatisfaction. In healthcare, this is particularly relevant. Patients are often presented with several treatment options, each with different benefits and risks. Instead of feeling informed, they may feel uncertain or anxious. This can result in delayed decisions or a tendency to rely entirely on the recommendation of a healthcare professional. Simplifying information and presenting options clearly can help patients feel more confident and engaged in decisions about their care. Affective Forecasting and Misjudging the Future Affective forecasting refers to how well people predict their future feelings. In most cases, these predictions are inaccurate. People tend to imagine ideal scenarios and overlook potential challenges. In healthcare, this means patients may not accurately anticipate how an illness or treatment will affect their everyday life. They may overestimate what they can manage or underestimate the emotional and physical impact of treatment. This gap between expectation and reality can lead to disappointment, reduced adherence and poorer outcomes. Providing realistic, experience based information can help patients make more informed decisions. The Peak End Rule and Patient Experience The peak end rule explains how people remember experiences. Rather than recalling every moment, individuals tend to focus on the most intense point and how the experience ends. In healthcare, this means patient perceptions are shaped by key moments, such as receiving a diagnosis, experiencing a complication or achieving a positive result. The final stages of care are also particularly important in shaping overall impressions. Even when most of the journey is positive, a negative moment or poor ending can have a strong impact on how the experience is remembered. On the other hand, positive moments and well managed endings can greatly improve patient satisfaction. Why This Matters for Healthcare and Pharma These behavioural insights have clear implications for healthcare providers and pharmaceutical companies. Decision making is influenced by more than just clinical evidence. It is also shaped by how information is presented and experienced. By simplifying complex choices, supporting realistic expectations and focusing on key moments in the patient journey, organisations can improve both decision making and patient experience. Bringing Behavioural Science Into Healthcare Planning a holiday may seem trivial, but it highlights important truths about human behaviour. In healthcare, these same patterns influence decisions that can have lasting effects. Applying behavioural science principles can help create more patient centred care. This means not only sharing the right information, but doing so in a way that reflects how people actually think and feel. Recognising the role of cognitive biases is a key step towards improving healthcare decision making and delivering better outcomes for patients and healthcare professionals alike.
