The Human Code Issue 9 // Decoding the DNA of Black Friday

Most business strategy relies on flawless logic, which is why it fails in a world governed by delightfully irrational human behaviour. Brand Genetics’ The Human Code is the antidote to spreadsheet-think – revealing the hidden motivations that drive brand growth.

For our ninth edition, we decode the DNA of ‘The Dopamine Hunt’ and why Black Friday has become a game.

For decades, Q4 promotional strategy assumed commercial success was simply a function of price: slash margins, shout louder, and race to the bottom of the discount ladder.

Today, over 70% of consumers plan a Black Friday ‘bargain hunt’, and 62% admit to buying items they neither planned for nor needed simply because the deal felt like a win. Yet, many marketers are still relying on blunt, sitewide markdowns to capture this demand.

Underneath the frenzied checkout queues lies a fundamentally different psychological dynamic. Where a traditional sale is rooted in rational saving, Black Friday is powered by the neurochemical thrill of the chase, where the discount becomes proof that the shopper outsmarted the system and won.

Brands treating Black Friday as a pure price event risk training shoppers to devalue them. Sustainable commercial growth requires moving beyond the discount to design offers that sell the thrill of the win.

Read Issue 9 below to explore the full breakdown.

Black Friday has stopped being a sale and become a game. Decoding the Dopamine Hunt, and how brands can sell the thrill of the win without sacrificing margin.
The Dopamine Hunt: Why Black Friday is a Game vs a Sale
November 2026
 
Over 70% of consumers plan a Black Friday ‘bargain hunt’—with 62% admitting they buy items they neither planned for nor need simply because the deal triggered a “win”
The DNA of Growth: Play the Game!
For most brands, the Q4 promotional playbook is an exercise in slashing margins, shouting louder, and racing to the bottom of the discount ladder
However, we know that strategy is commercially suicidal
Black Friday has never been a rational shopping event, but it’s still managed to evolve far beyond how it was initially conceived. Today, it is a live-action, high-stakes game that people can’t stop playing
Neuroscience reveals that the brain’s reward pathway hyperactivates during the anticipation of the chase. The discount has moved beyond the simple idea of saving money towards a hugely motivating metric that proves the consumer “won”
When brands offer blunt, sitewide 40% markdowns, they strip the consumer of the game. There is no skill, no scarcity, and no victory; only commoditisation
Don’t focus on selling discounts
Sell the thrill of the win
So what?
If your Black Friday strategy relies entirely on price cuts, you are training shoppers to devalue your brand
To protect margins and capture demand, stop thinking like a discounter, and start designing your offers like a game master
Read on to understand the behavioural DNA driving this shift…
 
DRIVERS (MOTIVATION)
The Dopamine Hunt
Where they once might have focused on searching for financial savings, consumers are now hunting for the neurochemical high of outsmarting the system
In the article below, we decode the neurobiology of anticipation and the four game mechanics brands must pull to win without sacrificing margin

ENABLERS (OPPORTUNITY)
The Architecture of the Arena
Context shapes choice. Black Friday succeeds because retail environments are engineered as multiplayer arenas vs traditional shop floors
The winners systematically manufacture the conditions of sport: clear victory conditions, artificial scarcity, and public friction that force shoppers onto the playing field
In The Atlantic, Ian Bogost explores this commercial tournament. For brands, the lesson is architectural: success can be found in the nuance of engineering high-stakes choice environments over passive price cuts

ABILITIES (PSYCHOLOGY & SKILL)
The Impact of Competitive Arousal
Under acute rivalry, rational calculation collapses. Psychologists call this ‘Competitive Arousal’ – an adrenaline-fuelled state where emotional arousal overrides reflective System 2 thinking
During Black Friday, cognitive bandwidth narrows dramatically. The consumer’s objective pivots from evaluating value to defeating competitors, turning the purchase into a status victory
For the BBC, researchers unpack why shoppers abandon logic in auction-like sales. The clear takeaway for brands is to move past the zero-sum game of discounting and protect margin by selling the thrill of victory
