Part 1: The Splurge and the Spiral: A Narrative
Section 1.1: The ‘Perfect’ Week
For two solid weeks, Sarah was perfect. She had drawn up a new, hyper-detailed budget, and this time, she was sticking to it. Every morning, she brewed coffee at home, packing it in a thermos. Every lunch was pre-planned and packed in Tupperware. She had declined after-work drinks, unsubscribed from retail emails, and dutifully logged every dollar not spent. Her budgeting app was a satisfying sea of green. She felt disciplined, organized, and, most importantly, in complete control.
This was the “ideal self” budget.1 It was built on the assumption that “future Sarah” would be a paragon of perfect self-control, immune to temptation or bad days. It was a budget that established a strict, “restrained” mindset 2, a cognitive boundary with zero room for error. It was, psychologically speaking, a trap waiting to be sprung.
Section 1.2: The Initial Violation
The trap sprung on a Tuesday. It was, by all accounts, a terrible day. A high-stakes project at work hit a major snag, her boss was audibly frustrated, and a cold rain had started to fall. On her walk from the office to the subway, tired and stressed, she passed a coffee shop. The smell of a pumpkin spice latte—a drink she loved but had deemed “frivolous”—wafted out. It felt like the only good, warm, comforting thing the world had to offer.
She bought the $6 latte. This was the “initial violation,” the “small splurge”.4 As the barista handed her the cup, she felt a sharp pang of guilt. Her perfect streak was broken. The “green checkmark” for the day was gone.5
Section 1.3: The “What-the-Hell” Cascade
That single $6 purchase broke the seal. The feeling of control was gone, replaced by the familiar sting of failure. And with it came a single, destructive thought.
“Well, I’ve already blown my ‘no spending’ day,” Sarah thought to herself. “My budget is ruined. What the hell…”.6
This thought, the “what-the-hell,” was the permission slip for a total “self-control collapse”.8 Because the day was already “ruined,” she decided she might as well “go all the way”.8 She skipped the Tupperware waiting in her bag and bought a $20 sushi platter for lunch. On her commute home, she scrolled through a shopping app. Her brain rationalized: “The budget’s already broken. I might as well get those shoes now and just ‘restart’ everything tomorrow”.9 A $150 purchase.
When she finally got home, she was too exhausted and demoralized to cook. “What’s the point now?” she thought. She ordered $40 of takeout. The day ended. Sarah’s “harmless” $6 splurge had “snowballed” 4 into a $216 spending spree. The budget wasn’t just bent; it was dead.
Part 2: Naming the Saboteur: The “What-the-Hell Effect”
Section 2.1: You’re Not Bad at Budgeting, You’re Just Human
Sarah’s story is not a unique tale of financial failure. It’s not a sign of weak character or a lack of discipline. It is, in fact, a predictable and well-documented psychological phenomenon.10 Her budget-killing cascade was a textbook example of the “What-the-Hell Effect.”
This effect describes the vicious cycle of indulgence, regret, and further indulgence.9 It is the tendency for people to abandon a goal—whether it’s cutting out sugar, quitting smoking, or sticking to a budget—the very moment they make a single, minor mistake.6
Section 2.2: The Science Behind the Name
While the name sounds colloquial, it is the official term used by researchers for a concept known in more formal literature as counter-regulatory eating.7
The term “counter-regulatory” means you behave in the opposite way that normal regulation would dictate. For example, after eating a large meal, “regulation” is the normal pattern of feeling full and reducing your food intake.12 “Counter-regulation” is the psychological tendency to eat more after having just consumed a large amount of food.12
This is precisely what Sarah did with her money. Instead of “regulating” her spending after the $6 splurge by stopping, she “counter-regulated” by spending even more. The What-the-Hell Effect (WTHE) was the cognitive snap that allowed her to do it.
Part 3: The Science of the “Snap”: From Milkshakes to Money
Section 3.1: The Famous “Milkshake Study”
To understand why this psychological snap happens, one must look at the foundational research. The term was coined by psychologists C. Peter Herman and Janet Polivy (then Polivy’s graduate student) in the 1970s following a now-famous experiment.2
The setup was clever. Researchers brought in two groups of participants: “restrained eaters” (people who were actively dieting) and “unrestrained eaters” (people who were not). They told them they were part of an “ice cream taste test”.13 But before the “taste test,” they gave some participants a “preload”—one or two large, high-calorie milkshakes.13
Logically, anyone who just drank a huge milkshake would be full and would, therefore, eat less ice cream afterward. This is exactly what the “unrestrained eaters” did. They regulated their intake.13
But the dieters did the exact opposite. The dieters who were “preloaded” with milkshakes ate significantly more ice cream than the dieters who had no preload at all.13 This was “counter-regulation” in action. The milkshake, in their minds, had already broken their “cognitive diet boundary”.2 Their internal monologue was pure WTHE: “I’ve already blown my diet with this milkshake, so… what the hell, I might as well eat and enjoy for now”.3
Section 3.2: The Real Trigger: The Perception of Failure
The milkshake study was just the beginning. Subsequent research refined this concept, revealing something even more profound: the WTHE isn’t triggered by actual failure, but by the perception of failure.
In one clever study, dieters were given a slice of pizza. Some were made to think their slice was larger than it really was. Afterward, those who thought they’d “blown their limit” (even though they hadn’t) went on to eat over 50% more cookies than those who didn’t.16
Another study gave participants the exact same milkshake but labeled it “high calorie” for one group and “low calorie” for the other. The “high-calorie” label alone was enough to breach the dieters’ cognitive boundary and trigger the WTHE binge.12
This is the key to understanding Sarah’s budget failure. It wasn’t the $6 latte that killed her budget; it was her labeling of the $6 latte as a “failure” that broke her “cognitive spending boundary” and gave her permission to binge.
Section 3.3: How “Cognitive Boundaries” Ruin Your Budget
This concept of a “cognitive boundary” applies to finance just as perfectly as it does to calories.
A powerful example is the “broken £20 note” analogy.17 A crisp $20 bill in a wallet feels like a “whole” boundary. People are often reluctant to “break” it for a small purchase. But the moment they buy that $6 latte, the boundary is broken. The $14 in change no longer feels like “real money”; it feels like “play money.” Once that boundary is gone, a person is “far likelier to buy things with the change”.17 The WTHE has been triggered on a micro-level.
The credit card is this phenomenon on steroids. A large credit card bill is, in essence, one giant, already-broken boundary. As behavioral economists have noted, a $100 splurge for dinner seems “smaller, less significant, and less painful” when viewed in the context of an existing $3,000 monthly credit card bill.8 The cognitive boundary is already so far in the rearview mirror that the WTHE kicks in. “You’ve already blown it,” the brain says, “so what the hell, another $100 won’t make a difference.” This “snowballs” 4 as consumers purchase other items on credit, adding to a total that begins to feel “insurmountable”.18
Part 4: The Psychological Engine: Why One Splurge is Never Just One
Section 4.1: The “All-or-Nothing” Trap
At its core, the What-the-Hell Effect is a cognitive bias rooted in an all-or-nothing mindset.19 It is a way of thinking that sees goals as binary: either 100% success or 100% failure. There is no middle ground.
This is the “planning fallacy” in action.1 When people like Sarah build budgets, they often do so for the “person they wish they were,” not the person they actually are.1 They create budgets that assume 100% compliance, failing to account for “unexpected expenses that inevitably arise” 21 or simple human desires.22
These hyper-strict, “unattainable” goals set the stage for the WTHE.23 A rigid, all-or-nothing budget is brittle. It cannot bend; it can only shatter. The moment reality (in the form of a $6 latte) collides with the “perfect” plan, the entire goal is perceived as a failure, leading to its complete abandonment.24
Section 4.2: The Cruel Irony: Guilt is the Fuel for the Fire
The cognitive “all-or-nothing” trap sets the stage, but the emotional engine of the WTHE is powered by a cruel irony: guilt.
Most people believe that feeling guilty is a brake on bad behavior. They think that if they are hard on themselves, they will be motivated to do better. But in the WTHE cycle, guilt is the accelerator.
Psychologist Kelly McGonigal, in her book The Willpower Instinct, details this destructive loop, which is perfectly illustrated by a writer who bakes chocolate peanut butter bars.9 The writer has one “just to taste,” then another, and another, until the entire pan is gone.9
This is the vicious cycle:
- Indulgence: A person gives in to a temptation—the latte, the cookie, the splurge.9
- Guilt & Shame: They immediately feel bad. They engage in harsh self-criticism: “I’m a loser,” “I’m lazy,” “I have no self-control”.5
- Stress Response: As research shows, these negative emotions of shame and guilt trigger a “pain” or “stress” response in the brain. The brain, sensing this distress, activates its reward center in a desperate attempt to protect the person and find a quick fix.5
- Misregulated Coping: And what is the “cheapest, fastest strategy for feeling better?”.6 To get a quick hit of pleasure or relief. Often, the brain turns to the very thing that caused the guilt in the first place—another splurge, more cookies, another purchase.9 This “reward” provides a temporary dopamine hit to escape the “hell” of self-criticism.5
This is the “snowballing”.4 It is not the first splurge that guarantees the relapse. It is the “feelings of shame, guilt, loss of control, and loss of hope that follow”.6
Part 5: Escaping the Cycle: A New Toolkit for Your Budget
Section 5.1: Antidote 1: Stop Making “Perfect” Budgets
The What-the-Hell Effect is, at its heart, a powerful argument for setting more realistic goals.17 The first step to disarming the WTHE is to stop building “all-or-nothing” budgets. One must stop budgeting for the “person you wish you were” and start budgeting for the person you are.1
The most effective solution is to plan for failure. A realistic budget must have “flexibility” and “slack” built in.21
This means creating a “safety valve” 17 within the budget. This can be called a “What-the-Hell Fund,” a “Miscellaneous” category, or a “Splurge” allocation. The name doesn’t matter; the psychological function does. By pre-allocating money for “unexpected” splurges, a person changes the cognitive frame. When they buy the $6 latte, they haven’t “broken” the budget; they have simply used a pre-allocated fund. The cognitive boundary remains intact, the “all-or-nothing” bias 19 is never triggered, and the shame-spiral is avoided.
Section 5.2: Antidote 2: The Surprising Power of Self-Compassion
This is the direct antidote to the guilt-indulgence loop.5 While it may feel counter-intuitive, the most effective way to increase self-control is to be less hard on oneself.
This was demonstrated in a study on self-compassion.
- The Setup: Researchers invited women who were on a diet to eat a doughnut.27
- The Intervention: Afterward, one group of women received a message of self-compassion, encouraging them not to be so hard on themselves for the indulgence. The other group received no such message.
- The “What-the-Hell” Test: Both groups were then left in a room with large bowls of candy and invited to eat as much as they wanted.
- The Result: The women who had been primed with self-compassion ate significantly less candy—only 28 grams. The group left to stew in their own guilt ate 70 grams, falling deep into the WTHE.27
Self-compassion is not a “license to splurge.” It is the single most effective tool for stopping a splurge from becoming a binge. It works because it increases a sense of personal responsibility by removing the paralyzing, demotivating effects of guilt and shame.28
When a slip-up happens, one should practice the three pillars of self-compassion 29:
- Mindfulness: Acknowledge the feeling without judgment. (“I’m feeling guilty about buying that latte.”)
- Common Humanity: Remind oneself of the shared human experience. (“Everyone overspends sometimes. It doesn’t mean I’m a bad person.”)
- Self-Kindness: Talk to oneself as a supportive friend, not an enemy. (“It’s okay. You had a hard day. This doesn’t define your entire financial future”).29
Section 5.3: Antidote 3: Adopt the “All-or-Something” Mindset
The final cognitive fix is to actively replace the “all-or-nothing” mindset with an “all-or-something” mindset.31
The WTHE thrives on the confusion between a “lapse” and a “relapse.” A lapse is a single event (one latte). A relapse is the complete abandonment of the goal (the $216 spending spree). The What-the-Hell Effect is the cognitive error of treating a lapse as if it’s a relapse.30
The solution is to reframe the lapse. As one researcher puts it, “If you run a red light (a lapse), you wouldn’t say, ‘Oh well, I’ve already run a red light. I might as well run five more.’ You’d say, ‘I made a mistake. I’ll be more careful’”.30 The same logic must be applied to finance.
This means using better self-talk in the moment of the lapse 7:
- “A little lapse doesn’t have to become a big relapse.”
- “I’ll forgive myself for this slip so I don’t make a bad situation worse.”
- “Stop the what-the-hell thinking already!”
This reframe turns the splurge from a “failure” into a “data point”.30 It becomes a learning opportunity, a chance to identify spending triggers—such as stress, boredom, or social pressure—and create a better plan for them next time.32
Part 6: The Recovery: Sarah’s Next Tuesday
Section 6.1: The Narrative Conclusion
One month later, Sarah finds herself in a familiar spot. It’s another terrible Tuesday. She’s stressed, she’s tired, and the coffee shop is right there. She buys the $6 latte.
The old “what-the-hell” voice starts to whisper: “You failed again… you’ll never get this right…”
But this time, Sarah is armed.
- She uses her Safety Net: She opens her budgeting app. Instead of a “failure,” she logs the purchase under her new “$50/month Fun Money” category. The budget is not broken.26
- She uses Self-Compassion: She takes a breath and tells herself, “It’s okay. This is exactly what this fund is for. I’m human, and I had a hard day”.29 The guilt-spiral is stopped before it can even begin.6
- She uses “All-or-Something”: She acknowledges the win. “I had a lapse,” she thinks, “but I’m stopping it from becoming a relapse. I’m still on track”.7
That evening, she goes home, eats the meal she had packed, and her $6 splurge remains just that: a $6 splurge. The “What-the-Hell” Effect, disarmed by a flexible plan and a little self-kindness, has lost its power.
Section 6.2: Final Takeaway
Financial discipline is not a game of perfection. The “all-or-nothing” approach is a setup for failure. True financial self-control is not about never making a mistake. It is about having a compassionate, realistic plan for the moments when you inevitably will.
