Behavioral Economics: Why We Don’t Always Act Rationally with Money
When it comes to money, many of us assume we make logical decisions. But research in behavioral economics shows that’s not always the case. People often make financial choices that go against their best interests—even when the facts are clear. This happens not because we’re careless, but because human behavior is shaped by mental shortcuts, emotional responses, and social influence.
In this post, we’ll explore the key ideas behind behavioral economics, why we sometimes act irrationally with money, and how we can become more aware of our financial decisions.
What Is Behavioral Economics?
Behavioral economics blends insights from psychology with traditional economic theory. Classical economics assumes people are rational actors who make decisions based on logic, facts, and maximizing utility. But behavioral economists argue that this is an oversimplification.
Instead, they look at how real people actually behave in financial situations. Behavioral economics examines:
- Cognitive biases that affect how we perceive value and risk
- Heuristics, or mental shortcuts we use to make quick decisions
- Emotions, like fear or excitement, that influence spending
- Social norms, such as peer pressure or marketing influence
By studying these factors, behavioral economics helps explain why our choices don’t always line up with what’s best for us financially.
Common Biases That Affect Financial Decisions
Our brains are wired to save time and energy by relying on shortcuts. While these shortcuts can be helpful, they can also lead us astray. Here are some common behavioral biases that affect how we manage money:
1. Loss Aversion
Loss aversion means we dislike losing money more than we enjoy gaining it. In fact, studies show that losing $100 feels about twice as bad as gaining $100 feels good.
- This can lead us to hold onto bad investments too long just to avoid realizing a loss.
- We might also avoid taking small risks, even when the potential reward is worth it.
2. Present Bias
We tend to prioritize short-term rewards over long-term gains. This is known as present bias.
- We might choose to spend money now rather than save for retirement.
- This explains why it’s easier to buy something enjoyable today—even if it puts long-term goals at risk.
3. Anchoring
Anchoring happens when we rely too much on the first piece of information we receive.
- For example, if an item was originally priced at $100 but is on sale for $70, we think it’s a good deal—even if it’s not worth $70.
- Anchoring is common in retail, where original prices are set high to make discounts seem more attractive.
4. Confirmation Bias
We seek out information that supports what we already believe and ignore evidence that challenges our views.
- If we think a certain investment is good, we’ll focus on news that confirms this belief.
- This can prevent us from objectively assessing financial risks.
Real-Life Examples of Irrational Financial Behavior
Behavioral economics is not just theory—it plays out in everyday decisions. Let’s look at a few real-world examples:
1. Spending on Brands vs. Alternatives
Many people pay more for well-known e cigarette brands, even when similar products are available at lower prices. This isn’t always about quality; it can also be due to perceived value, social influence, or loyalty to a brand name.
- Behavioral economics explains that status signaling and brand familiarity influence these choices.
- People often associate higher price with higher value, even when that’s not objectively true.
2. Impulse Purchases
Whether it’s a pair of shoes or a cheap vape, impulse purchases are driven more by emotion than by logic. Stores use behavioral triggers like:
- Limited-time offers to create urgency
- Eye-catching displays to draw attention
- Free shipping thresholds to nudge buyers into spending more
These methods exploit our tendency to seek quick rewards and avoid missing out.
3. Subscription Traps
Many people sign up for free trials and forget to cancel them. Companies use default settings to auto-renew subscriptions, knowing that:
- People are more likely to go with the default than take action.
- Inertia and forgetfulness lead to continued payments, even when the service isn’t used.
How to Make Better Money Decisions
Understanding the biases that affect our choices is the first step toward making better financial decisions. Here are a few tips based on behavioral economics research:
1. Set Clear Goals
People are more likely to save or invest when they have specific goals in mind.
- Set targets for short-term and long-term savings.
- Automate contributions to avoid present bias.
2. Use “Nudges” to Your Advantage
A “nudge” is a small change in the way choices are presented that influences behavior.
- Try setting up automatic savings or investment plans.
- Use apps that round up purchases and save the difference.
3. Reframe Choices
How options are framed impacts decisions.
- Instead of thinking, “I’ll lose $100 if I invest,” try thinking, “I have the chance to gain $150.”
- Reframing can reduce the emotional impact of loss aversion.
4. Avoid Decision Fatigue
Making too many financial decisions in a short time can lead to poor choices.
- Limit big financial decisions to times when you’re mentally fresh.
- Prepare a checklist or decision framework to stay focused.
5. Compare, Don’t Anchor
Before buying or investing, compare multiple options objectively.
- Don’t rely solely on the first price you see.
- Look for independent reviews or tools to evaluate products or services.
Final Thoughts
Behavioral economics shows us that we’re not always the rational actors classical economics assumes. We’re human—shaped by biases, emotions, and habits. By becoming more aware of these influences, we can improve how we handle money.
Understanding how people really make decisions isn’t just interesting—it’s practical. Whether you’re choosing between e cigarette brands or deciding whether to invest, recognizing the hidden forces at play can help you act with more clarity.
