Why More Choices Make You a Worse Shopper

In 2000, psychologists Sheena Iyengar and Mark Lepper ran a jam study. One day, a supermarket offered 24 jams for tasting. Another day, just 6. The 24-jam display attracted more visitors. The 6-jam display generated ten times more sales.

We've known about the paradox of choice for a quarter century. Shopping apps still refuse to believe it.

The Problem With "More"

Open any major e-commerce search and you'll find thousands of results for any query. Filters help, but only a little — you're still choosing between 47 versions of roughly the same thing. Review scores converge. Price differences feel arbitrary. Eventually you either buy the top result by default or abandon the cart.

Neither outcome is a good shopping experience. One produces regret ("did I get the best one?"). The other produces nothing.

The platforms know this, but their incentive is engagement, not decision quality. More options means more time on site. More time on site means more ad impressions. The paradox of choice is, for them, a feature.

How Most "Curated" Apps Fail

The word "curated" has been aggressively diluted. Most curated shopping experiences are just filters on top of the same massive catalogue: "Top 10 blenders" articles that list 10 versions of the same 3 brands, ranked by affiliate commission rate.

True curation requires a point of view. It requires the curator to make a decision on your behalf — not to hedge by listing every option and letting you figure it out.

The Diffr Approach

Diffr's answer is structural: we make one recommendation per slot. If you're building a photography kit, there's one camera body recommendation, one lens, one bag, one tripod. Not "top 5 camera bags for beginners" — one bag, chosen because it fits the scene.

This forces us to have an actual opinion. It forces the recommendation to be meaningful. And it forces the shopper to engage with a real choice — "does this scene match what I want?" — rather than a paralysing meta-choice about which list to trust.

What Constraint Creates

The no-repeat principle has an unexpected benefit beyond reduced choice: it maps the space of a scene. When every product slot has a different brand, you learn something about the brand landscape. You discover that the best travel tripod comes from a company you'd never heard of. You notice that the bag recommendation is from a brand that doesn't appear anywhere else in the photography kit — meaning they specialise.

That's information. Most shopping lists bury it under brand familiarity and ad spend.

Better Decisions, Not Fewer Decisions

We're not trying to make shopping require less thought. We're trying to make the thought you put in count for more. A Diffr scene is a starting point for a decision, not a decision made for you. But it's a starting point with real signal — not a ranked list of whoever paid the most to appear at the top.

If you're tired of shopping apps that give you more when you need less, Diffr is building something different.
