# Commercial Liking Models Case studies of how compliance professionals systematically deploy the liking rule in commercial contexts. From Chapter 5 of *Influence: The Psychology of Persuasion* by Robert B. Cialdini. --- ## Model 1: Joe Girard — The Liking Formula Distilled ### Profile - Guinness World Records: "world's greatest car salesman" for 12 consecutive years - Income: more than $200,000/year as a showroom floor salesman - Average: more than 5 cars and trucks sold every day he worked - Source: Chevrolet dealership, Detroit ### The Formula "It consisted of offering people just two things: a fair price and someone they liked to buy from. And that it," claimed in interview. "Finding the salesman they like, plus the price; put them both together, and you get a deal." ### The Mechanism - Fair price alone is not enough — dozens of salespeople can offer fair prices - The differentiator was manufactured liking at scale - Primary tactic: **Compliments at scale via mass direct mail** ### The Card System - Every month, sent a holiday greeting card to every one of his 13,000+ former customers - Card changed monthly (Happy New Year, Happy Thanksgiving, Happy Valentine's Day, etc.) - Message on the face of the card: always and only "I like you" - Nothing else: no upsell, no offer, no product mention — just his name and "I like you" - Annual volume: well over 150,000 cards per year - Cost: significant printing and mailing expense ### Why It Works - Demonstrates the flattery principle: liking even obviously impersonal, obviously commercial praise - The recipients knew exactly what Joe was doing; they still liked him - "Joe understands an important fact about human nature: We are phenomenal suckers for flattery." - Even when the praise is clearly false or commercially motivated, humans tend to believe praise and like those who provide it ### Lesson for Application The card system demonstrates that the liking rule does not require subtlety. A direct, repeated, mass-produced expression of positive feeling still works — because the automatic response to being liked is to like in return. The lesson is not to copy the method exactly but to understand the principle: sustained, regular expressions of genuine regard build liking that converts to compliance. --- ## Model 2: Tupperware Party — All Six Principles, Liking as the Center ### Structure - Party hosted by a housewife (the hostess) in her home - Tupperware demonstrator is physically present but is not the real requester - The compliance pressure comes from the hostess — a friend of every person in the room ### Why It Dominates Retail - Tupperware abandoned retail outlets entirely - A party now starts somewhere every 2.7 seconds globally - Estimated sales exceeding $2.5 million per day (at time of publication) ### The Social Bond as Compliance Engine Consumer researchers Frenzen and Davis (examined social ties between hostess and partygoers) found: the strength of the social bond between hostess and partygoer is TWICE as likely to determine product purchase as is preference for the product itself. The product preference is irrelevant compared to the friendship pressure. ### All Six Principles in Play 1. **Reciprocity** — games are played, prizes are given; everyone receives a gift before buying begins 2. **Commitment** — each participant publicly describes the uses and benefits of Tupperware she already owns 3. **Social Proof** — once buying begins, each purchase signals that similar people want the product 4. **Liking** — the true requester is the hostess, a friend; the company provides her with financial motivation 5. **Authority** — the Tupperware demonstrator provides product expertise and credibility 6. **Scarcity** — implied by limited party availability and specific product assortments ### The Hostess Arrangement - Tupperware Home Parties Corporation gives the hostess a percentage of every sale - The hostess calls friends together for the demonstration - Her financial interest is hidden behind the friendship frame - Partygoers feel they are buying from a friend, not a stranger - "By providing the hostess with a percentage of the take, the Tupperware Home Parties Corporation arranges for its customers to buy from and for a friend" ### Participant Awareness Fully aware, many guests still comply. One woman quoted: "It's gotten to the point now where I hate to be invited to Tupperware parties. I've got all the containers I need; and if I wanted any more, I could buy another brand cheaper in the store. But when a friend calls up, I feel like I have to go. And when I get there, I feel like I have to buy something. What can I do? It's for one of my friends." ### Lesson for Application The Tupperware model reveals that liking transfers through social networks — the friend's relationship does the compliance work. The compliance professional (Tupperware demonstrator) doesn't need to manufacture personal liking; they leverage existing liking between the hostess and her friends. For product and brand strategy: giving trusted advocates financial or social incentive to promote a product to their own networks is structurally more powerful than direct persuasion. --- ## Model 3: Shaklee Corporation — The Endless Chain ### Profile - Door-to-door sales of home-related products - Proprietary method: "endless chain" for finding new customers ### The Method 1. Salesperson closes a sale with a customer 2. Asks the customer for the names of friends who would also appreciate learning about the product 3. Those friends are approached by the salesperson, who mentions that the mutual friend suggested the visit 4. Each new customer yields a new list of names — the chain extends indefinitely ### The Key Lever: Liking Transfers Through the Referral Name - "The key to the success of this method is that each new prospect is visited by a salesperson armed with the name of a friend 'who suggested I call on you.'" - Turning the salesperson away under those circumstances is almost like rejecting the friend - The Shaklee sales manual: "It would be impossible to overestimate its value. Phoning or calling on a prospect and being able to say that Mr. So-and-so, a friend of his, felt he would benefit by giving you a few moments of his time is virtually as good as a sale 50 percent made before you enter." ### Why It Works - The friend doesn't even need to be present - Simply mentioning the friend's name invokes the liking the prospect has for that friend - The compliance professional benefits from a relationship they didn't build and a liking they didn't earn - Rejection of the salesperson feels like rejection of the friend ### Lesson for Application Referrals work not because of endorsement logic but because of the liking transfer. A referral moves the liking the customer has for their friend onto the salesperson before they've even met. In modern terms: referral programs, testimonials from people the prospect knows or respects, and word-of-mouth marketing all operate on this mechanism. The friend's name (or the trusted figure's endorsement) is the active ingredient. --- ## Model 4: MCI Calling Circle — Liking Disguised as Savings ### The Scheme - Long-distance phone company (MCI) created "MCI Friends and Family Calling Circle" - A customer's friend is added to the calling circle without their consent - MCI salesperson calls the non-customer and explains: "Your friend Brad placed you on his Calling Circle. He can save 20% on calls to you if you switch to MCI." ### The Pressure Structure - The financial benefit is framed as being for the friend, not for the prospect - Refusing to switch means refusing to help save Brad money - "For me to say that I didn't want to be in his Calling Circle and didn't care about saving him money would have sounded like a real affront to our friendship when he learned of it." - The prospect switches to MCI to protect the friendship, not because they wanted MCI ### Effectiveness - MCI salesperson quoted by Consumer Reports: "It works nine out of ten times." ### Lesson for Application The MCI model reveals the weaponization of liking through social obligation: by framing a compliance request as an act of friendship maintenance rather than a commercial transaction, compliance rates approach 90%. The "friend as the requester" frame is among the most powerful structures in commercial persuasion. This is also why any tactic that hijacks friendship networks to generate commercial compliance carries significant ethical risk — it exploits the trust built by genuine relationships. --- ## Summary: Common Patterns Across Commercial Models | Model | Primary liking factor exploited | Key mechanism | |-------|--------------------------------|---------------| | Joe Girard | Compliments | Mass-scale personal appreciation at regular intervals | | Tupperware | Familiarity + all five factors | Friendship network transfers existing liking to purchase decision | | Shaklee | Familiarity + similarity | Referral name invokes existing liking before first contact | | MCI Calling Circle | Familiarity | Frames commercial compliance as friendship maintenance | All four models share one insight: **the friend doesn't need to be present for liking to transfer**. The association of a trusted name, a consistent reminder of appreciation, or a network that channels pre-existing friendship into commercial settings is sufficient. Compliance professionals don't have to earn liking themselves — they borrow it from existing relationships.
