The research — why choice complexity kills conversion
Choice overload is a documented behavioral phenomenon,
not a hypothesis
The relationship between the number of decisions required and the likelihood of completing a purchase is established across behavioral economics, consumer goods, and education enrollment research. These are the most directly relevant findings.

More purchases with 6 choices than 24
Shoppers at a grocery store encountered either 24 varieties of jam or 6. The larger display drew more traffic — 60% of passers-by stopped. But only 3% bought anything. The smaller display drew fewer browsers — 40% stopped — but 30% made a purchase. Ten times the conversion rate with one quarter of the options.
This finding has since been replicated in retirement investment accounts, online retail, healthcare decisions, and speed-dating contexts. The mechanism is consistent: when the cost of making the "wrong" choice feels high, more options produce paralysis rather than confidence. At $3,000–$7,000+ per course, that effect is significantly amplified.
Bain & Company — Consumer Goods SKU Research
+17%
Revenue with 42% fewer SKUs (Belgium food brand)
Bain's research on SKU simplification documented a consistent pattern across consumer goods categories: selling less often leads to selling more. A Belgian food brand grew revenues 17% after cutting 42% of product variants. A Swedish candy brand grew sales 19% with 18% fewer items.
Procter & Gamble cut Head & Shoulders from 26 variants to 15 — sales rose 10%. When you remove low-performing options, your strongest offerings get more attention, fill faster, and carry more marketing support. Shelf clarity — physical or digital — accelerates purchase.
Knight & Schiff — NBER, 2019

Applications when colleges reduced enrollment friction
When colleges joined the Common Application — consolidating what had been separate, school-specific applications into a single shared form — applications rose by 12%, growing to 25% over a decade. This is the most direct parallel to OBUSA's situation: a fragmented multi-school system where each institution required families to navigate independently, creating redundant effort and confusion.
The desirability of those colleges did not change. The experiences they offered did not change. Applications increased simply because the barrier of navigating multiple systems was removed.

The bottleneck is not the application. Families who start it complete it at 84%. The drop happens earlier — in the multi-step course-finding process before they ever reach an application. That is exactly where the research above predicts choice overload concentrates.
