How to utilise this in your designs

For a feature-heavy interface, you could offer a "lite" mode that strips out advanced components, so newer users aren't carrying the cognitive load of an expert tool.

Webull Lite UI shows a 361.03 stock price, monthly chart trends in dark mode with red/green bars. A blue-bordered white box states "Webull Lite, Simple and Easy Experience."

Example from

WeBull

When asking for a subjective rating, you could anchor each option to something obvious, e.g., whether you can still talk, so people don't have to interpret an abstract scale.

Black UI panels show exercise intensity levels 1, 7, and 9 with white bold numbers and labels; underlined orange text emphasizes "walking slowly," "hard to talk," and "no talking."

Example from

Nike

During onboarding, you might force people to pick one goal at a time, so they're not holding several competing decisions in working memory at once.

White modal card with padlock icon, "Stay focused on your current habit" header, explanatory text, blue-link "Tell me more," progress circle 0/1 reps, and "Close" button top right.

Example from

Atoms

Raw scores make people do mental maths, so you could frame results relative to other users, removing the load of working out whether a number is good.

Dark-mode UI with orange bar showing "Average solving time 5.84 seconds" beating 96% users; green performance insights show score 802 beating 3%, rank Beginner to Novice.

Example from

Peak

If a task genuinely needs concentration, a "lives" mechanic could raise the stakes enough that people accept the higher cognitive load rather than skim.

Example from

Duolingo

Possible impacts

People actively leave stressful situations, so trimming the mental strain of early flows could mean fewer users abandoning you before they reach any value.

WeBull It's WeBull, but lite

Atoms Atom's forced friction

Keeping load inside the 'Goldilocks zone' may help people work through tasks faster, as less working memory is spent decoding the interface itself.

Lego Keeping track of your totals

A heavy but interesting task still holds attention, so balancing cognitive load rather than removing it entirely might keep people willing to push on.

High cognitive load on something dull is draining, so cutting unnecessary mental work could make the experience feel noticeably more enjoyable.

Overloaded people default to the easiest option, so simplifying and contextualising choices may give you more accurate answers at sign-up and onboarding.

Strain on short-term memory is uncomfortable, so lightening it could mean less frustration and stress attached to using your product.
