63% of Black Friday shoppers don't trust that the discounts they're offered are legitimate.

They buy anyway.

Ipsos B&A ran this survey for the Irish Competition and Consumer Protection Commission in October 2025. Nationally representative sample. One-thousand-and-thirty-four consumers. 63% expressing mistrust. 39% saying they plan to buy during the sales period - up from 36% the year before.

This is not a contradiction.

It's the most important thing a marketer can understand about Black Friday.

The consumer who knows the original price was inflated. Who's read about fake countdown timers. Who understands that "limited stock" often isn't. Who has regretted a previous Black Friday purchase. Who has, in some cases, specifically told someone they're not going to fall for it this year.

That consumer still buys.

Not because they're irrational. Not because the manipulation worked on them despite their awareness. But because Black Friday operates on a different psychological register than a normal sale, one that doesn't require deception to be effective, and that works on savvy shoppers for reasons that have nothing to do with them being deceived.

This issue is about that psychology. What actually drives Black Friday purchasing. What the permission structure is that makes it different from any other sale of the year. And what this means for the brands building their November campaigns right now.

Understanding why it works is the first step to building a campaign that earns its results rather than manufacturing them.

The five psychological mechanisms behind Black Friday purchasing — and why awareness doesn't neutralise them

The naive account of Black Friday psychology is that brands trick consumers. They inflate reference prices. They manufacture scarcity. They create false urgency. Consumers who know about these tactics are protected. Consumers who don't are taken advantage of.

This account is wrong or at least, radically incomplete.

The more accurate account: Black Friday activates psychological mechanisms that operate independently of whether the consumer can name them. Knowing about loss aversion doesn't protect you from loss aversion. Understanding anchoring doesn't make the anchor disappear. Awareness of FOMO doesn't reduce the emotional weight of missing something.

The five mechanisms:

1. Loss aversion and the asymmetry of missing out

Loss aversion - the finding that losing something hurts roughly twice as much as gaining the same thing feels good - is the engine under most Black Friday behaviour. The framing of Black Friday isn't "gain 20%". It's "don't lose 20%". The countdown timer isn't about what you'll receive. It's about what you'll give up if you don't act.

The consumer who understands loss aversion can name it. They can tell you Kahneman and Tversky described it in 1979. They can explain the roughly 2:1 ratio. They will still feel the pull of a deadline more acutely than the pull of a static price, because the psychology is operating on a substrate that conscious recognition doesn't reach.

2. Anchoring and the power of crossed-out prices

The first price a consumer sees becomes the anchor against which all subsequent prices are judged. A product listed at £200, marked down to £120, is processed as "a £80 saving" rather than "a £120 product." The anchor is the reference point.

The consumer who knows about anchoring will look at a crossed-out price with more scepticism than an unaware consumer. But they still need a reference point. Their scepticism doesn't eliminate the anchor, it raises the bar the anchor needs to clear. The brand with a credible, genuine discount against a real pre-sale price is still using anchoring. The difference is that their anchor bears scrutiny, and the sceptical consumer's scrutiny validates rather than undermines the purchase.

3. The permission structure of designated occasion

This is the mechanism that receives the least attention and explains the most.

Black Friday is a culturally designated occasion for spending. It functions like a permission slip. The consumer who would feel guilty spending £300 on themselves on a random Tuesday in September has different internal accounting for the same £300 spent at Black Friday.

The deal provides the justification. It's rational - "I saved £80." It's social - "everyone is buying now." It's seasonal - "this is the time." The permission structure means the internal resistance that normally accompanies discretionary spending is partially suspended. The consumer can buy without the usual cost of deliberation and guilt.

This is why 72% of Black Friday shoppers (in the CHOICE 2025 survey) said the event helps them save money on things they would have bought anyway. They're not being tricked. They've been waiting, consciously or unconsciously, for a cultural permission structure that makes the purchase feel appropriate.

4. Shopping momentum and the cascade effect

Yale SOM research (Nathan Novemsky and Ravi Dhar) identifies what they call shopping momentum: a purchase can set off a chain of unrelated buying decisions. The first purchase acts as a signal to the self - "I am in buying mode today." Subsequent purchases that would have felt unjustified before the first one now feel consistent with the established self-concept of the session.

This explains why the average Black Friday shopper spends £397 (NRF 2023 data) when they came in expecting to buy one or two specific things. The first purchase legitimised the session. The momentum carried the spending.

5. Social proof and the herd signal

Nearly two-thirds of Black Friday shoppers report being influenced by limited-time sales (CCPC, 2025). The limited-time frame isn't just a deadline, it's evidence that others are participating. The popularity of the event signals value. If millions of people are buying right now, the item being bought probably warrants buying.

The consumer who knows about social proof is less susceptible to manufactured social cues, fake "X people are viewing this right now" notifications, fabricated review counts, inflated "best-seller" claims. But genuine social proof, real reviews, real popularity indicators, actual crowds - still carries weight, even for the sceptical consumer.

→ Takeaway: Audit your Black Friday campaign against the five mechanisms. Are you activating loss aversion with a genuine deadline or a manufactured one? Is your anchor price a real pre-sale price or an inflated reference? Is your scarcity structural or fabricated? The consumer who knows the tricks can tell the difference and the consumer who knows the tricks is your most valuable customer.

What the psychology of Black Friday means for your email campaign

The most actionable implication of Black Friday psychology for email marketers is the permission structure.

Black Friday is one of a small number of moments in the year when the cultural context shifts the internal accounting of your subscriber. The purchase they've been postponing. The item they've been watching. The self-gift they haven't quite justified. Black Friday gives them a frame that makes the purchase feel legitimate, not impulsive.

This has two implications:

Implication 1: Your job is to lower the remaining barriers, not create artificial pressure.

The consumer who has been watching a product for three months doesn't need a countdown timer to create urgency. They need confirmation that this is the moment — that the deal is real, that the scarcity is genuine, that buying now is the rational choice. The email that does this job converts better than the email that creates manufactured pressure, because the subscriber's internal resistance isn't about urgency, it's about legitimacy.

"This is the lowest price we'll set this year" is a permission-granting statement. "ONLY 4 HOURS LEFT!!!" is a manufactured pressure statement. The first works on the savvy consumer. The second triggers their scepticism.

Implication 2: The waiting customer is your highest-value segment.

The consumer who has been in your ecosystem since Phase 1 of the Black Friday planning cycle - receiving your emails, seeing your content, putting items in their cart and removing them, is not a neutral consumer waiting to be converted. They're a primed consumer waiting for permission.

The email that works for this segment is the one that recognises the wait. "You've had your eye on this." "We know you've been thinking about it." The personalised early-access email that names the category they've been browsing, confirms the deal is genuine, and removes the remaining decision barrier.

That subscriber doesn't need to be sold. They need to be given permission.

Three email types that exploit the permission structure:

The early-access email (send this week): "You're getting access to our Black Friday prices before anyone else. Here's why." The exclusivity of early access provides its own permission justification — the subscriber isn't participating in the mass event. They're receiving something specific to their relationship with the brand.

The wait-acknowledgement email: "You've been looking at [product]. Black Friday is the moment." Requires personalisation and a browsing or cart-abandonment signal. The most effective email you can send to a high-intent subscriber who hasn't converted.

The legitimate-anchor email: "This is what we charged in August. This is what we're charging now. Here's the reason." The transparent anchor email that validates scepticism rather than triggering it and converts the consumer who would have dismissed a fake countdown timer.

→ Takeaway: Look at your BF email sequence. For each email: is it creating pressure or providing permission? Pressure emails activate the scepticism of your savvy subscribers and convert only the least resistant part of your list. Permission emails — the ones that confirm the deal is real, acknowledge the wait, and remove the remaining decision barrier — work on everyone.

53% of Black Friday buyers in a 2025 survey regretted at least one purchase. Here's what that means for your brand.

The CHOICE 2025 survey of Australian Black Friday shoppers found:

These are not statistics about manipulation victims. They're statistics about the downstream cost of campaigns that created artificial pressure without legitimate permission and about brands that used the occasion to move inventory rather than create genuine value.

The regret data is a competitive signal.

The brand that leaves its Black Friday buyer with regret has not won that customer at Black Friday. It has exchanged a full-price future purchase for a discounted present one, and created a post-purchase experience that makes the repeat purchase less likely.

The brand whose Black Friday buyer does not regret the purchase has done something different: it has created the combination of genuine deal value, legitimate permission, and product satisfaction that turns a Black Friday buyer into a repeat customer.

The practical implication: Black Friday campaigns built on genuine value - real discounts, real scarcity, real early access for subscribers who've earned it - produce buyers with lower regret rates and higher lifetime values. Campaigns built on artificial pressure and inflated anchors produce higher short-term conversion rates and lower long-term returns.

The 63% distrust figure is not a problem to solve. It's a positioning opportunity. The brand that earns trust in a climate of distrust earns a disproportionate share of the high-value customers who have been burned before and are looking for a reason to believe in a deal.

→ Takeaway: After BF, track your post-purchase email sequence open and click rates against your BF buyers. Monitor unsubscribes. Look at return rates. These metrics will tell you whether your campaign created buyers or extracted purchases. The difference determines what those customers do in February.

Your own post-purchase survey — set it up before Black Friday

The most underused tool in the BF marketer's stack is a post-purchase survey sent 7–14 days after delivery.

Two questions:

The answers to question 2 tell you which mechanism drove the purchase — genuine deal value, early access exclusivity, specific product intent, social proof, deadline pressure. That data is the input to next year's campaign design.

If most buyers say "I'd been thinking about it for a while and BF felt like the right moment" — you have evidence of the permission structure at work, and your campaign should lean into early-access and wait-acknowledgement framing.

If most buyers say "I saw a countdown timer and didn't want to miss out" — you have evidence of pressure-driven conversion with a higher regret risk. That's the signal to rebuild the campaign around legitimacy.

Klaviyo, Typeform, or a simple two-question Google Form delivered via your post-purchase flow. Set it up now. The data you get in December is worth more than any pre-campaign research.

Audit your Black Friday campaign against the permission structure.

For each email in your planned BF sequence, ask one question:

Is this email creating pressure or providing permission?

Pressure email: countdown timer, manufactured scarcity, "don't miss out" framing, urgency for urgency's sake.

Permission email: genuine deal confirmation ("this is the lowest price of the year"), wait acknowledgement ("you've been looking at this"), legitimate anchor ("here's what we charged in August"), early-access framing ("you're seeing this before anyone else").

The consumer who's been burned before - 53% of last year's BF buyers regretted at least one purchase, is a sceptical consumer who converts on permission and bounces on pressure.

The consumer who hasn't been burned yet converts on both. But the consumer who converts on permission is the one who comes back.

Build the campaign for the customer you want in February, not just the conversion you want in November.
