How to utilise this in your designs

When users face a large library, you could try a 'roll the dice' button that suggests a random read, removing the decision fatigue of choosing what to read next.

App UI shows navigation with "For you," "Explore" (highlighted blue), and "Library" tabs. "Roll the dice" button offers random summary. Book summary "Happier Hour" by Cassie Holmes, 7 key points, 13 min read listed.

You could add a 'Surprise me' option to a snooze menu, so decision-fatigued users can skip picking an exact time and let the product choose for them.

Dark navy "Bubble Up" modal on pale lavender background with radio options (radio buttons): Now; Tomorrow (Tue 8am); This weekend (Sat 8am); Next week (Sun 8am); Surprise me (orange arrow/underline, "???" right); Pick a date (8am).

Try pre-filling a document name with the user's first line of text and auto-highlighting it, so there's one less decision to make and it's quick to overwrite.

Google Docs UI with "Untitled document" highlighted in red, text "The thing about Mars is..." underlined in red and blue-labeled text "The thing about Mars is..." selected.

You could experiment with curated, shareable lists of meals from other users, narrowing a huge menu into fewer options to ease decision fatigue at mealtimes.

EatLists UI on Swiggy app: intro modal with orange "Proceed" button, explaining favorite dish recommendations; main screen shows three Eatlists categories with food images.
Example from

Consider limiting new users to one habit at a time, rather than letting them set up several at once, so decision fatigue doesn't lead them to fail and give up.

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.

Possible impacts

Reducing the number of decisions in a flow could lift conversion rates, as decision-fatigued users may otherwise put off choosing and abandon before completing.

Setting good defaults and focusing on one change at a time might help users to form new habits, as decision fatigue makes adopting several at once much harder.

Splitting a journey into smaller sessions could help sustain users' motivation, as fewer choices per session means less mental effort before decision fatigue sets in.

Adding context to choices, e.g., descriptive scales or smart defaults, may improve the quality of user inputs, as fatigued users are less likely to answer carelessly.
