In short
The Labor Illusion effect means people value a result more when they see the time and effort spent on it. Before the purchase offer, show the steps your product takes to build the user’s personalized plan, keep the wait under 30 seconds, display progress, and speed the loader up toward the end instead of showing a bare spinner.
The essence of the Labor Illusion effect: if something happens quickly and without visible effort, it “seems” less valuable, less high-quality, etc.
Research has shown that people value work more if they understand that significant time and effort were spent on its completion.
For example, home buyers were divided into two groups:
Both groups were shown the same houses → participants who believed the search took 9 hours rated the houses 36% higher.
Often, buyers value effort more than speed.
This way, the user will find it easier to part with their money.

💡 Example, Blinkist app: shows the processing of user data (their goals, book preferences) to create a personalized plan.
Be careful: if the user does not understand the meaning of the loading or processing, it may confuse and repel them more than help.

❌ When the progress indicator (Loading) does not show the loading status:
There is neither a loading indicator nor explanations of how long to wait → create tension (what if the app is frozen), rather than increasing trust.




What to consider when using the effect:

💡 Weight Loss Running by Slimkit and stoic show the sequence of steps they take “behind the scenes” when forming a personalized plan.
Remember your emotions when the loading freezes at 99%. Is it worth making the user nervous before asking them for money? 😉
2. Avoid using a “loading indicator” (spinning circle) without numbers or a filling bar; it does not show the time until completion → uncertainty makes people nervous.

3. For a loading indicator with animated diagonal stripes, the movement of the stripes from right to left reduces the perception of waiting time.

4. Animations should be smooth (rendered at 60 frames per second).
A slight delay before providing the result and illustrating the work done by the product significantly affects the perception of its “value” → fairness of the price → conversion to purchase.
However:
