Illusive Design Pattern
Passing costs on to the user for profit.
- When purchasing Amazon Fresh groceries, a tip is added automatically based on the total cost with no feedback provided. The user is primed and then made to feel guilty for removing it.
- Apps like DigitalOcean and LinkTree have a default pricing option selected.
- Conformity Bias
- Self-serving Bias
- Status Play: The user status is lowered as they are primed into feeling guilty for changing the amount.
- Jumping to Conclusions - Where did this come from?
- Catastrophizing - What if the driver knows I didn’t tip?
- Personalization - Feel guilty for not giving tip.
- Blaming - They make me feel bad.
- Should - I should tip them as they need probably it.
- Transparency: Reduce anxiety by removing uncertainty and explaining algorithm updates.
- Expectations: Reduce stress by providing control and reassurance of outcome.
- F Pattern: Illusive pattern is applied outside the scannable area.
Don Norman Principles
- Feedback: An extra charge was added with no feedback provided.
- Visibility: The text is small and overpowered by all the other content.
Jakob Nielson Principles
- Visibility: Same as above.
- Match Real World: Asking for a tip upfront is considered to be unethical and breaks real world interaction and cultural norms.
