Why the cheapest tier exists to be rejected

Three tiers are offered and the lowest is transparently insufficient: too few seats, a missing feature everyone needs, a limit that will be reached in a week. It sells rarely and is retained anyway, because its function is to be examined and dismissed on the way to the option that was always intended.

What everyone sees

A poorly selling tier is read as a mistake or as a legacy offer nobody removed. Occasionally correct. But the same structure recurs across unrelated industries with a consistent shape — lowest option deficient in one salient dimension — which is a stronger indication of design than of accident.

What is actually happening

Huber, Payne and Puto showed that introducing an option dominated by an existing one raises the share of the option that dominates it, an effect that violates the assumption that adding an alternative cannot help a specific incumbent. Simonson and Tversky extended this with tradeoff contrast and extremeness aversion, finding that a choice set with three graded options concentrates selection in the middle by making the extremes look like sacrifices. In both accounts the rejected option does work: it supplies the contrast against which another option is judged, and without it the middle tier would be evaluated on its own price rather than as a considered improvement.

Why it stays hidden

The design hides because rejecting the cheap tier feels like independent judgement. The buyer notices the deficiency themselves, reasons about it, and chooses accordingly, so the conclusion arrives as their own analysis. The set they were reasoning within is the part that was chosen for them, and the set is not visible as a decision.
