6 Ways Psychology Explains Black Friday Shopping

For weeks, I’ve been refreshing Amazon.com, searching for the perfect deal on a digital piano. My goal? To play Christmas tunes for my 17-month-old baby girl and make this holiday season extra special. Yet, every time I spot a “bargain,” I hesitate: Am I actually saving money, or am I being outsmarted by clever marketing? As a marketing professor, you’d think I’d know better. But, embarrassingly, I find myself falling victim to these tactics far too often. It's a classic case of the shoemaker without shoes.

If you’ve ever felt this tug-of-war between logic and emotion while bargain hunting, you’re in good company. Black Friday has a unique way of sparking behaviors that seem completely irrational. But these reactions aren’t random; they’re deeply rooted in human psychology. So why does this annual shopping event have the power to make millions of us act as if snagging a discounted gadget is a matter of life and death? Let’s find out.

First, Black Friday deals are often not actually the best discounts of the year. Many companies use algorithm-driven dynamic pricing based on consumer data, which means that some items may be priced similarly—or even lower—during other sales throughout the year. Yet, year after year, we eagerly line up outside stores at dawn or crash e-commerce servers with our frantic clicks. This isn't about logic; it's about emotion. Black Friday isn't just a shopping event; it's a psychological battleground where our instincts take over.

The Thrill and Fear of Missing Out

Imagine this: You're eyeing a limited-edition smartwatch, and there are only "two left in stock." Your heart races, your palms sweat, and you click "Buy Now" faster than you can think. This ambiguous mix of excitement and anxiety is carefully engineered by marketers. Scarcity cues—like low stock warnings and countdown timers—create urgency, triggering our fear of missing out (FOMO). FOMO isn't just a catchy acronym; it's a psychological response rooted in loss aversion. It describes how the pain of losing an opportunity is far more powerful than the joy of gaining something.

But there's more at play here. Black Friday also taps into our desire to feel victorious. Grabbing a deal feels like winning a game—a sentiment amplified by the festive atmosphere, crowds, and competitive dynamics. We're not just buying products; we're "beating" others to a prize.

As I engage in my personal quest for a more musical holiday season, I've decided to take a closer look at the psychological principles that make Black Friday so irresistible:

The Scarcity Principle

The scarcity principle posits that people assign more value to opportunities that are less available. On Black Friday, retailers exploit this by offering "limited-time" deals and "exclusive" products. When we perceive something as scarce, our desire to obtain it intensifies. This urgency often leads to impulsive buying decisions, as we fear that delaying might result in missing out entirely.

Social Proof

The concept of social proof suggests that individuals look to others' behavior to determine their own actions. During Black Friday, the sight of crowded stores, long lines, and social media posts showcasing purchases creates a bandwagon effect. We assume that if so many people are participating, the deals must be worthwhile. This collective behavior reinforces our decision to join in, even if we hadn't planned to shop initially.

Reference Price Theory

According to reference price theory, consumers evaluate prices based on an internal "reference price"—a standard they believe is fair. Retailers manipulate this by displaying inflated original prices alongside discounted ones. Even if the final price isn't a genuine bargain, the contrast makes the discount appear more substantial, compelling us to make a purchase we might otherwise skip.

Emotion-Based Decision Making

Emotions play a pivotal role in our purchasing decisions. Decades of consumer research tell us that emotional responses can significantly influence consumer behavior. The festive atmosphere of Black Friday—complete with holiday music, vibrant displays, and the thrill of competition—elicits strong emotional reactions. These emotions can override rational thinking, leading us to make purchases driven by excitement rather than necessity. After all, what is consumption, if not an exciting experience?

The Endowment Effect

Once we add an item to our cart—whether it’s sitting in a physical shopping cart or resting in the digital recesses of an online cart—it starts to feel like it’s already ours. Psychologists call this the endowment effect, and it’s why letting go becomes so much harder. Take my digital piano. I had been eyeing it for weeks, researching deals, reading reviews, and imagining myself playing Christmas carols for my toddler. At some point, it wasn’t just a piano anymore; it was my piano. It had already taken residence in my imagination and, more importantly, my Amazon cart.

When Amazon's Black Friday Week kicked off this morning, I noticed the discount was worse than before, and the price had actually gone up by €40 compared to two weeks ago. I hesitated. The logical side of my brain screamed, "Wait for a better deal!" But another voice—more emotional and much louder—whispered, "You’ve been dreaming about this piano. What if someone else buys it? What if it sells out?" With each refresh of the page, my anxiety grew. That “15% off” tag glared at me (although it had been 30% off just two weeks ago), as if daring me to give up on my musical Christmas dreams.

In the end, I caved. I hit “Buy Now,” even though I knew I was no longer getting the best price. But as soon as the confirmation email landed in my inbox, relief and excitement swept over me. The piano was finally mine—overpriced, yes, but firmly mine. And that, my friends, is how the endowment effect, paired with the fear of losing a deal, wins every time.

Embracing Conscious Consumption

As the adrenaline fades and we unpack our Black Friday hauls, many of us feel a twinge of regret: Did we really need that extra gadget? Was the discount worth the stress? Black Friday reminds us of a universal truth: Emotions, not logic, often guide our decisions. But it also offers an opportunity for reflection.

This year, let's embrace a different approach. Don’t be like me; plan your purchases strategically, focus on what truly adds value to your life, and remember the joy of giving—not just to others, but also to yourself. Conscious consumption isn't about deprivation; it's about aligning your spending with your values. Let’s reclaim the holiday season as a time of connection, gratitude, and thoughtful choices.
