Avoid Choice Overload and Cognitive Overhead

Kosh's "Choose a savings plan" screen lists twelve plans in a table with columns such as "lock-in", "effective annual yield" and "premature withdrawal penalty". Users who reach it spend a long time there, and most leave without choosing any plan. Nothing on the screen is false. There is just far too much of it.

The rule

Offer few, distinct options, and never make users do work the screen could do.

Conscious decisions use up attention, and attention runs out. Two things waste it.

Choice overload. When there are many options, especially similar ones, people can find it hard to choose. They postpone, pick nothing, or feel less happy with what they picked. The effect is not universal — it depends on how complex the options are and how clear the person's preferences are — but for newcomers facing unfamiliar choices it shows up often.

Cognitive overhead. This is all the mental work that is not the decision itself: decoding jargon, remembering a number from a previous screen, doing arithmetic, working out what a label means. Every bit of it drains attention away from the actual choice.

The remedies:

• Fewer options, each meaningfully different in a way users care about.
• A sensible starting point, marked as recommended, with the others still visible.
• Plain words instead of jargon.
• Do the maths for the user and show the result.
• Reveal detail on request, so the main screen carries only what the decision needs.

The shortcut

Count and cut. Count the options, the terms a newcomer would have to look up, and the things they must calculate or remember. Cut each count until what remains is the decision itself.

The trap is cutting options until the remaining ones no longer differ in anything important. Three nearly identical plans are not simpler than twelve; they are just fewer.

Drills

Answer fast — trust the rule.

Remember

• Offer few, distinct options, and never make users do work the screen could do.
• Shortcut: count and cut — options, jargon, calculations — until only the decision remains.
• Trap: options so similar that cutting them changes nothing.
