Every ad that stops a thumb is selling to a want the viewer had before they opened the app. The creator and the edit only decide whether that want gets noticed in time. In Cashvertising, Drew Eric Whitman boils those wants down to a short list he calls the Life Force 8: eight desires he argues are built into all of us, plus nine weaker ones we pick up along the way. It gets quoted constantly in direct response circles and used far less, because most marketers read the list, agree with it, and go straight back to briefing ads by format.
That order is backwards. A new format changes how an ad looks. A new desire changes why anyone would care, and that's the bigger lever and usually the cheaper test. Brief the desire first and the format finally has something to carry.
The Life Force 8 hook matrix
Whitman's eight, in his order and close to his wording (this review of the book lists them the same way). The hook lines are illustrative examples written for this guide. They aren't real ads and they don't come with results.
| Desire | What it sounds like | Worked hook (illustrative) | Fits | Common misuse |
|---|---|---|---|---|
| 1. Survival, enjoyment of life, life extension | Energy, feeling like yourself again, more good years | "I'm 41 and I've stopped needing a 3pm coffee." | Supplements, functional drinks, fitness | Health promises the product can't back up. Longevity is a claim, not a vibe. |
| 2. Enjoyment of food and beverages | Taste, texture, the first bite or sip | "It tastes like the milk at the bottom of a cereal bowl." | Snacks, coffee, drinks, meal kits | Opening on macros or ingredients when the viewer wants to know if it's nice. |
| 3. Freedom from fear, pain and danger | Relief, a risk removed, a problem that stops | "Ten winters of cracked heels. This is the first one in sandals." | Skincare, foot and body care, home safety, pet health | Manufactured fear the product can't fix. It works fast, so it gets overdone. |
| 4. Sexual companionship | Being noticed, attraction, confidence up close | "He asked what perfume I was wearing. It's body wash." | Fragrance, grooming, body care, oral care | Spelling it out. Meta restricts sexually explicit language in ads, and innuendo reads cheap; the compliment does the work. |
| 5. Comfortable living conditions | Ease at home, better sleep, a calmer space | "I didn't know my bedroom was the problem until I changed the light in it." | Home, bedding, sleep, cleaning | Listing specs (thread count, lumens) without the feeling of living with them. |
| 6. To be superior, winning, keeping up with the Joneses | Status, being first, beating a benchmark | "My neighbour had the best lawn on the street. Had." | Garden, fitness gear, coffee kit, tech accessories | Smugness. Status that sneers at the viewer loses them, and named-rival comparisons need proof. |
| 7. Care and protection of loved ones | Kids, partners, parents, pets | "I read the back of my dog's food bag properly for the first time. Then I switched." | Pet food and care, baby, family nutrition, home safety | Guilt. A parent made to feel negligent scrolls on; a parent made to feel capable buys. |
| 8. Social approval | Compliments, belonging, not being judged | "Three people at work asked if I'd been away." | Skincare, beauty, oral care, fragrance | Insecurity tactics. Meta's health and wellness rules bar weight loss and cosmetic ads that attack a person's appearance. |
Put simply, the Life Force 8 are the eight desires Whitman argues drive most buying decisions: survival and enjoyment of life, food and drink, freedom from fear and pain, sexual companionship, comfortable living, being superior, caring for loved ones and social approval. Give each hook one of them as its job. Write the opening so the viewer feels that want going unmet, then let the product settle it.
Two notes on reading the matrix. The Fits column is a starting point, not a rule. Pet food can sell on taste (the dog's), on care (yours) or on status (the best-kept dog in the park), and the interesting tests usually sit in the column you hadn't thought of. And the misuse column matters more than it looks. Desires 3, 4 and 8 carry the most power and the most policy risk. Meta's health and wellness advertising standards rule out weight loss and cosmetic ads containing "statements of inferiority about physical appearance", including lines that attack someone's body or hygiene, which is exactly where a careless social approval hook ends up.
What a desire hook actually does: tension, desire, action
Whitman's model of why these work is simple. An unmet need creates tension, tension creates desire, and desire produces action. Hunger is the textbook case, and summaries of the book lay out the same chain: tension leads to desire leads to action.
For a hook, that means the first two seconds have one job: make the viewer feel the tension, rather than describing it to them. "Ten winters of cracked heels" works because the viewer who has them winces before the sentence ends. A product shot can't do that on its own, which is why so many polished brand openers die in the feed.
Desire 3 deserves a word of its own. In their 1979 paper on prospect theory, Kahneman and Tversky proposed that the value function people use is "generally steeper for losses than for gains". In plain terms, a loss stings more than the same-sized gain pleases. That's why a hook about a pain stopping or a risk going away often beats the same product sold as a nice extra. It's also why fear is the desire most often pushed too far. Sell against a loss your customer already lives with, rather than inventing one for them.
Where the Life Force 8 meets Schwartz
The LF8 tells you which desire to sell to. It says nothing about how directly to name it, and that's where Eugene Schwartz comes in. His stages of awareness decide how openly the hook can mention the problem or product, and his levels of market sophistication decide how much new mechanism or proof the claim needs before anyone believes it. Same desire, different execution at each stage.
Here's one desire carried through every awareness stage, for an illustrative magnesium sleep drink selling to comfortable living (desire 5):
| Awareness stage | What the hook has to do | Illustrative hook |
|---|---|---|
| Unaware | Make the tension felt with no product in sight | "I thought waking up at 3am every night was just getting older." |
| Problem aware | Name the problem and say it can be fixed | "If you fall asleep fine but wake at 3am, it might not be stress." |
| Solution aware | Show why this kind of fix beats the others | "I swapped my late-night phone scroll for this at 9pm." |
| Product aware | Close the gap with proof or a demo | "Two weeks of my sleep tracker, before and after switching." |
| Most aware | Give a reason to buy now | "The 30-night tub is back in stock." |
Sophistication adds one more choice, and it's the one we'd push hardest. When a category gets crowded, every brand selling to the same desire escalates the claim: faster, stronger, more. Switching desire is often the cheaper way out. If every sleep brand sells comfortable living, the one that sells care for loved ones ("I stopped waking my wife up at 3am") is saying something new without having to promise more.
The nine learned wants, and why they make weak leads
Whitman's second list covers wants we learn rather than inherit. He treats them as weaker than the eight, and Ben Putano's summary lists them as: to be informed, curiosity, cleanliness of body and surroundings, efficiency, convenience, dependability and quality, expression of beauty and style, economy and profit, and bargains.
| Learned want | Pairs best with | Where it earns its place |
|---|---|---|
| To be informed | 3. Freedom from fear | The "what nobody tells you" line that follows the hook |
| Curiosity | Any of the eight | The open loop that keeps the hook watched to the end |
| Cleanliness of body and surroundings | 5. Comfortable living, 8. Social approval | A satisfying demo |
| Efficiency | 5. Comfortable living | Time saved, shown on screen |
| Convenience | 5. Comfortable living | The step in the routine that disappears |
| Dependability and quality | 7. Care for loved ones | Reassurance before the CTA |
| Expression of beauty and style | 8. Social approval, 6. Being superior | The b-roll, not the opening line |
| Economy and profit | 6. Being superior (the smart buyer) | The value argument mid-ad |
| Bargains | None on its own | The offer and the CTA |
Our rule of thumb: a learned want can carry the middle of an ad, almost never the first line. "Saves you ten minutes" is efficiency, and nobody stops for it. "I get ten more minutes in bed" is comfortable living wearing efficiency's clothes, and people do. Curiosity is the one exception worth knowing. It's less a desire than a delivery device, which is why it pairs with any of the eight; our guide to curiosity hooks and the information gap goes into how to build one.
How do you audit a live account by desire?
This takes an afternoon and a spreadsheet, and it usually changes the next month's briefs.
- Export the last 60 to 90 days at ad level, with spend and your main result (purchases, CPA, ROAS, whatever you actually optimise for).
- Tag every ad with one primary desire, the one its first three seconds sell to. One tag only. Most ads touch two or three desires, and Maslow made the same point in 1943: "Typically an act has more than one motivation." For an audit, you still have to pick the one doing the work in the hook.
- Sum spend and results by desire. Two columns are enough: share of spend and the best result any ad in that desire has reached.
- Look at the shape. Don't be surprised if one or two desires carry nearly all the spend. That's the usual result when briefs start from format and the desire gets chosen by habit.
- Pick the next test from the gaps. Take the untested desire that fits the product most naturally (the matrix's Fits column helps) and brief three hooks for it.
- Hold everything else still. Same format, same creator, same offer as your current best ad, so desire is the only thing that changed. Then give each ad enough spend to read; our guide on how much to spend per creative test sets the thresholds.
To stop doing this by hand every quarter, put the desire in the ad name. The angle field in our ad creative naming convention is built for exactly this, so results roll up by desire in any export.
Why we test desire before format
Format tests are popular because they're easy to see. Testimonial versus unboxing, green screen versus street interview. But a format test on the same desire mostly reshuffles the same message for the same people. A desire test changes who the ad is for. On Meta, where the creative now does much of the targeting, that's the difference between finding a new pocket of buyers and paying to reach the old one in a new costume.
So in our own briefs, desire is a field of its own, chosen before format, alongside persona and angle. A winning ad then gets new formats built around the desire that won, which is the point where format tests start paying off. The same thinking sits behind our seven hook angles and the wider set of UGC ad hooks that convert: pick why the viewer should care, then work out how to show it.
If you'd rather hand the desire mapping, scripting and testing to a team that does it every week, here's how we work and what it costs. There's more on hooks and copy in the resources library.
Life Force 8 FAQs
What is the Life Force 8?
The Life Force 8 (LF8) is Drew Eric Whitman's list, from his book Cashvertising, of eight desires he says are built into everyone: survival and enjoyment of life; food and drink; freedom from fear, pain and danger; sexual companionship; comfortable living conditions; being superior; care and protection of loved ones; and social approval. Whitman argues that ads selling to one of them get attention more easily than ads built on learned wants.
What are the 9 learned wants in Cashvertising?
To be informed, curiosity, cleanliness of body and surroundings, efficiency, convenience, dependability and quality, expression of beauty and style, economy and profit, and bargains. Whitman treats them as learned rather than built in, and weaker than the Life Force 8. In ads they work best as support for an LF8 hook rather than as the hook itself.
Is the Life Force 8 the same as Maslow's hierarchy of needs?
No. Maslow's 1943 theory arranges needs in a hierarchy, where one need usually appears once a more basic one is satisfied. The Life Force 8 is a working list for copywriters, not a theory of how needs build on each other. Maslow is useful for understanding people; the LF8 is built for briefing ads.
How do you use the Life Force 8 in UGC ads?
Give each script one primary desire and put it in the first line the creator says. Then test desires against each other with format, creator and offer held the same, and tag each ad's desire in its name so results add up by desire rather than ad by ad.
