The Dopamine Trap: Why Spending Feels Good
In this blog, we’ll explore why spending money can feel so satisfying in the moment, and why that sense of satisfaction doesn’t always work in our favour. Drawing on neuroscience, behavioural psychology, and personal finance insights, we’ll unpack the mechanisms that drive impulsive spending and offer practical ways to manage those behaviours more mindfully.
Why Does Spending Feel So Good?
When you make a purchase, particularly something you’ve been looking forward to, your brain rewards you with a surge of dopamine. While dopamine is often referred to as the “pleasure chemical,” this label only tells part of the story. Neuroscientists now understand that dopamine primarily governs motivation and anticipation, rather than simply pleasure itself. It plays a crucial role in driving us toward rewards, whether that reward is a delicious meal, social validation, or a new pair of trainers.
A landmark study from the University of Michigan found that dopamine levels are highest not after receiving a reward, but during the period of anticipation. This helps explain why browsing online shops, watching unboxing videos, or adding items to a cart can be so emotionally stimulating. We experience a mental boost from the expectation of a purchase more than from actually owning the item.
What was once an evolutionary mechanism designed to help us seek food, shelter, and connection is now frequently triggered by consumer products, promotional sales, and next-day delivery services. As a result, the modern shopping experience is finely tuned to exploit this natural dopamine response.
Emotional Spending: When Money Manages Mood
Spending is not just about seeking pleasure; for many people, it also becomes a method for coping with emotional discomfort. If you’ve ever found yourself shopping after a difficult day in an attempt to feel better, then you’ve experienced emotional spending.
Psychological research supports this behaviour. A 2011 study published in the Journal of Consumer Psychology found that shopping can help people regain a sense of control during emotionally challenging times. Making a purchase, particularly a small and manageable one, provides temporary relief and a sense of agency.
However, this relief is often short-lived. Emotional spending can develop into a cycle where negative feelings trigger shopping, followed by regret or guilt, which in turn leads to more emotional discomfort and further spending. Over time, this becomes a habitual pattern.
This cycle is also linked to the concept of hedonic adaptation, which describes how people quickly return to a baseline level of happiness after a positive experience. That exciting new item you bought might lift your mood initially, but it soon blends into your daily life, prompting the search for the next “fix.”
The Behavioural Economics of Impulse
Many of us struggle to follow through on long-term financial intentions because of present bias, a well-documented cognitive bias in behavioural economics. Present bias describes our natural tendency to favour immediate rewards over delayed ones, even when the delayed outcome is clearly more beneficial.
A typical example would be planning to save £100 this month, but then deciding to spend £40 on an unplanned dinner, telling yourself that you'll save more next time. The present feels more urgent and real than the distant future, which makes it harder to resist temptation.
Nobel Prize-winning economist Richard Thaler, co-author of Nudge, has shown through extensive research that people often fail to act in their long-term interests. This is not usually due to a lack of knowledge, but rather the influence of biases like present bias and overconfidence. People often overestimate the happiness a new purchase will bring, while underestimating the long-term impact of continued spending.
Another related concept is hyperbolic discounting, where people assign disproportionately high value to immediate rewards compared to future ones. This explains why someone might choose £50 today over £100 in a month, even though waiting would clearly be the better decision.
Friction: A Behavioural Brake on Spending
The modern retail environment is intentionally designed to make spending as easy and convenient as possible. Features such as saved payment details, rapid checkout systems, and "Buy Now, Pay Later" services eliminate barriers that would otherwise give us time to reconsider.
However, studies from the Behavioural Insights Team in the UK have shown that reintroducing small points of friction—such as requiring users to review their purchase or click through additional steps—can significantly reduce impulsive decisions. These brief moments of reflection increase cognitive engagement, which can be enough to steer us towards more intentional spending.
In practical terms, friction encourages us to pause and reflect. Even a small interruption in the process can make a meaningful difference.
How to Break the Dopamine-Spending Cycle
One of the simplest and most effective techniques to manage impulsive spending is to introduce a delay between the desire to buy and the actual purchase. The 24-hour rule, for instance, involves waiting at least a day before buying any non-essential item. This gives your emotional response time to settle, allowing for more rational decision-making. Many people find that after this pause, the urge has diminished or the item no longer feels necessary.
Another powerful strategy involves tracking your emotional triggers. Keep a simple journal or note on your phone to log what you bought, how you felt before the purchase, and how you felt afterwards. Over time, you may begin to notice patterns, such as shopping more when you're stressed, tired, or lonely. Recognising these emotional links can help you respond differently next time those feelings arise.
Reducing exposure to temptation is also an important part of the process. This could mean unsubscribing from promotional emails, turning off sale notifications, or unfollowing social media accounts that prompt feelings of comparison or inadequacy. When you see fewer triggers, you experience fewer urges to spend impulsively.
It is also worth exploring alternative ways to engage your brain’s reward system. Physical activity, creative hobbies, social connection, and setting achievable goals can all provide a similar sense of satisfaction. Even completing small tasks or ticking off a to-do list item can deliver the dopamine hit your brain is seeking—without the cost.
For some, using cash for discretionary spending can make a significant difference. When you pay with cash, the physical act of handing over money feels more concrete and makes you more mindful of your spending. Once the cash is gone, you are naturally prompted to stop and reassess.
Finally, your financial goals should be emotionally compelling, not just numerical. Rather than vaguely aiming to “save more,” take time to visualise exactly what you’re saving for. It might be a holiday, a home upgrade, or simply the peace of mind that comes with financial security. According to research in behavioural science, emotionally resonant goals are much more effective than abstract ones when it comes to sustaining motivation.
Final Thoughts
Spending money can be a positive and fulfilling experience when it aligns with your values and priorities. However, when it becomes a go-to coping mechanism or a response to emotional discomfort, it can begin to erode your long-term financial wellbeing.
Understanding the dopamine trap is not about blaming yourself or avoiding spending altogether. Rather, it is about increasing your awareness of the psychological and emotional drivers behind your financial decisions. With that understanding, you can begin to insert small pauses, increase your sense of control, and replace automatic habits with intentional ones.
The most rewarding financial decisions are not necessarily those that bring instant excitement. Instead, they are the ones that move you closer to a stable, meaningful, and purpose-driven life.
