Bait and Switch

Every airline runs the same play. The fare is $49. By the time you've selected a seat, checked a bag, and paid the booking fee, the total is $187. The original price was never the price. It was the bait — the number that got you into the funnel, past the point where comparing alternatives felt like more effort than paying the difference. The Federal Trade Commission defined bait-and-switch advertising in 1960 as offering a product with no intention of selling it as advertised, then steering the customer toward something different — typically more expensive, lower quality, or both. In its illegal form, it is straightforward fraud: advertise a television at $199, tell the customer who shows up that it's "sold out," and push them toward a $599 model. In its legal form, it is one of the most widespread competitive tactics in modern business.

The distinction between illegal bait and switch and legitimate strategic selling is thinner than any business school will admit. The car dealership that advertises a base-model sedan at $22,000 and then walks you through $8,000 in "recommended" packages is not breaking the law — the base model exists, technically, somewhere on the lot. The SaaS company that offers a free plan with feature walls engineered to make the product unusable without upgrading is not committing fraud — the free plan works, technically, for someone. The recruiter who posts a "Senior Product Manager at a leading tech company" listing and then presents you with a junior role at a subsidiary is not violating any statute — the listing was "directional." In each case, the offer that attracted you and the offer you received are different products separated by a gap the seller profits from. That gap is the mechanism.

Bait and switch works because of a fundamental asymmetry in effort. The seller invests once in the bait — the advertisement, the listing, the pricing page — and reaps the reward across thousands of customer interactions. The customer invests individually — time comparing options, driving to the store, filling out the application, building expectations — and faces that investment as a sunk cost at the moment the switch occurs. The customer who has spent forty minutes at the dealership, already imagining the car in their driveway, is psychologically disposed to accept the $8,000 in add-ons rather than start the process over at another dealer. The customer who has spent three months building workflows on the free SaaS plan is psychologically disposed to pay the upgrade rather than migrate to a competitor. The bait creates commitment. The switch exploits it.

The model's range extends from petty retail fraud to civilisation-scale strategy. P. T. Barnum built the most profitable entertainment enterprise of the nineteenth century on the principle that the advertisement and the experience need not be the same thing — they just need to be close enough that the customer, having already committed, finds the experience worth the price of admission. Ray Kroc pitched prospective franchisees on the dream of owning a restaurant, then built a real estate empire on their rent payments. Modern technology companies have industrialised the tactic: free tiers that degrade into paywalls, introductory pricing that resets to full rate, marketplaces that court third-party sellers and then compete against them using their own data. The vocabulary changes — "land and expand," "value ladder," "freemium conversion" — but the structural logic is identical. Attract with one thing. Deliver another. Profit from the gap.
