Decoy Pricing and Asymmetric Dominance: How a Third Option Reshapes the First Choice

Decoy pricing is a specific application of the asymmetric dominance effect: when a consumer is choosing between two options and you add a third option that is clearly inferior to one of them (but not the other), the consumer shifts preference toward the option that dominates the decoy.

The classic example: Consumers choosing between a $279 bread maker and no bread maker at all were split. When a $429 bread maker was added, sales of the $279 model doubled. The $429 model barely sold -- but it was not supposed to. It served as a decoy that reframed $279 from "expensive kitchen gadget" to "reasonably priced kitchen gadget."

In GBB, the decoy dynamic operates naturally. The Best tier serves as a soft decoy for the Better tier -- not because Best is inferior, but because its high price makes Better's price-to-quality ratio look exceptional.

However, deliberate decoy pricing goes further. Some brands introduce a product specifically designed to be dominated by the target product:
- Same quality as Better but at a higher price (price decoy)
- Same price as Better but with fewer features (feature decoy)
- Slightly larger than Better but at a disproportionately higher price (value decoy)

The decoy does not need to sell. It just needs to be visible at the point of decision.

Effective Decoy Position: The decoy must be clearly dominated by the target on at least one dimension while being comparable or slightly better on another.

Dominance Check:
Target is preferred to Decoy if:
- Target Price <= Decoy Price AND Target Quality >= Decoy Quality
OR
- Target offers better value ratio: (Quality_Target / Price_Target) > (Quality_Decoy / Price_Decoy)

Decoy Effectiveness = Volume Shift to Target / Volume of Decoy
High effectiveness means low decoy sales but significant target uplift. Ratios of 3-5x are typical.

Example:
Without decoy: Product A at $3.49 (45% share), Product B at $5.99 (55% share)
Add decoy: Product C at $5.49 with same features as A
New shares: Product A at $3.49 (52% share), Product B at $5.99 (42% share), Product C (6% share)
Product A gained 7pp. Decoy C captured 6%. Decoy Effectiveness = 7/6 = 1.17x

The decoy shifted more volume to the target than it captured itself -- a successful decoy deployment.

A coffee brand used decoy pricing to drive sales of their target product:

Original lineup:
- Standard Blend 200g at $4.99: 62% share
- Premium Blend 200g at $7.99: 38% share

The Premium Blend was their target product (higher margin) but consumers saw $7.99 as expensive.

Decoy added: Premium Blend 150g at $6.99
- Same coffee quality as Premium 200g
- Worse value per gram: $4.66/100g vs $4.00/100g for Premium 200g
- Clearly dominated by Premium 200g on every rational dimension

New shares:
- Standard 200g at $4.99: 42% share (-20 pts)
- Premium 200g at $7.99: 44% share (+6 pts)
- Premium 150g at $6.99 (decoy): 14% share

The Premium 200g gained 6 percentage points of share. The decoy itself captured 14% -- more than expected, because some consumers genuinely wanted a smaller premium format. The decoy accidentally became a real product serving a real occasion (portion control for premium coffee).

Total premium revenue increased 58%. Even the 150g "decoy" contributed meaningfully at a 48% gross margin. The lesson: a well-designed decoy can serve dual duty as both a psychological anchor and a legitimate portfolio offering.

Deliberate decoy pricing is more common than most practitioners admit:

1. The "stepping stone" decoy: A pack size positioned between Good and Better that offers slightly less value per unit than Better. Consumers compare the two and Better wins. This is common in beverages where a 750ml bottle at $3.49 makes the 1L bottle at $3.99 look like much better value.

2. The "phantom" decoy: A product listed in the retailer's system and shown on shelf but rarely in stock. Its price tag is visible, creating the anchoring effect, but consumers cannot actually buy it. Ethically questionable but occasionally observed.

3. The "format" decoy: A multi-pack format (e.g., 3x100g at $4.99) positioned next to a single larger pack (400g at $3.99). The multi-pack is objectively worse value per gram, but its presence makes the large pack look like a deal. The multi-pack still sells to consumers who value portion control.

4. Seasonal decoys: Limited-edition premium products that serve as temporary anchors during peak selling periods (Christmas, Easter). They shift the mix upward for the season without requiring permanent SKU commitment.

5. Guard against ethical pitfalls: The decoy should still be a legitimate product that delivers value to the consumers who buy it. A deliberate rip-off product undermines trust and brand reputation over time.
