In 2000, two Columbia professors set up a jam tasting table at a grocery store. Some days they put out 24 jams. Other days, just 6. When the table had 24 options, 60% of shoppers stopped, but only 3% bought. When it had 6, fewer people stopped (40%), but 30% of them purchased.
More choices, fewer sales. It's been one of the most cited findings in consumer psychology for 25 years. Every eCommerce marketer has heard of it. Most treat it as a fun data point and move on. Very few have worked out what it actually means for how their Shopify store shows products.
What choice overload does to a buyer
Choice overload is the cognitive fatigue that sets in when too many options force too many comparisons. When the cost of deciding feels too high, the brain defaults to not deciding at all.
Barry Schwartz expanded on this in "The Paradox of Choice," arguing that beyond a certain threshold, more options reduce satisfaction, increase anxiety, and lower the probability of purchase. He documented this across financial decisions, medical choices, and consumer goods. Online shopping isn't any different — if anything, it's worse. A grocery shopper who walks away from a jam display still has to eat something eventually. An eCommerce visitor who gets overwhelmed just opens a new tab.
Baymard Institute found that 17% of cart abandonments happen because checkout is too complicated, but that figure understates where the real damage happens. The confusion that drives abandonment usually starts earlier, during browse and discovery, when a customer can't find what they're looking for and quietly gives up before they ever reach a cart.
How this plays out on a typical Shopify store
A merchant with 500 products doesn't show all 500 on one page. But they do show 24–48 items per category page, with filters most customers never touch, and a search bar that returns results ranked by keyword match.
A customer who types "summer dress" might get 60 results: sundresses, cocktail dresses with "summer" buried in the product description, and a few items that barely qualify. The customer has to sort through all of it to find what they're actually looking for. Most don't bother, and it shows up in the data as a bounce — not as evidence of a discovery problem.
The average Shopify store has around 450 products. The average visitor sees fewer than 10. That gap is where revenue quietly disappears. Customers who can't find what they want usually don't ask for help. They close the tab.
