The principle. Sheena Iyengar's famous Stanford jam study: a tasting table with 24 jam flavors attracted more browsers but only 3% bought. A 6-flavor table attracted fewer browsers but 30% bought — a 10x conversion gap.
Why. More options = more cognitive load = analysis paralysis = decision deferral. The brain's escape valve from too many choices is to choose none.
Where reps blow it. Pricing pages with 5 tiers. Demos that show every feature. Proposals with 4 packages and 3 add-on bundles. Each option you add lowers the conversion rate of the option you actually want them to pick.
The fix: the rule of 3. Present at most 3 options. The Goldilocks structure:
- Anchor (high) — premium tier, sets the ceiling. Most won't pick it. That's fine — it's an anchor.
- Target (middle) — the option you actually want them to choose. Optimized to feel like the obvious right answer.
- Decoy (low) — bare-bones, makes the target look like a steal by comparison.
The asymmetric dominance effect. The decoy is intentionally worse on most dimensions than the target — but only slightly cheaper. This makes the target look strictly better. Brain takes the shortcut and picks it.
Where it really matters. End-of-call. Don't say "so, we've got these 5 things we could do — what works for you?" Say "based on what you've told me, two paths make sense — option A or option B. Which feels right?" Two options, not five. Built-in alternative close.
Caveat for technical buyers. Engineers and CFOs sometimes WANT the spec sheet. Show 3 options up front; have the full menu in the appendix for the prospect who asks.
