Roach Motel and Lean Processes

How to Apply

Provide a clear “undo” or “cancel” option on every step, with predictable results.
Show progress with a short step indicator and let users move backward without penalty.
Use simple, consistent button labels like “Start trial”, “End trial”, “Delete account” with no ambiguity.
Place entry and exit actions in the same settings area, with parallel layouts and similar effort.

Dark Pattern

Roach Motel

Starting an action is easy, but leaving or reversing it is difficult.

Roach Motel subverts the user’s expectation that an action will be as easy to reverse as it is to make, instead creating a situation that is easy to get into, but difficult to get out of.

Lean Processes

Open →

Keep processes as simple and short as possible for the user.

Processes should be as simple and short as technically possible for the user. Design userflows in a way that a user can still fully graps and if needed decide on an action, but keep unneeded additional steps away that could possibly confuse or manipulate the user.

Approach: semantic vs flipping

Two different approaches to Bright Patterns:

Semantic Approach

This approach is used by Sandhaus. It defines concrete Bright Patterns for specific contexts — for example the Bright Pattern "Usage Limits", which describes an interface that restricts the usage time of a service to a healthy level.

Flipping Dark Patterns

The original way the term "Bright Pattern" was introduced: the direction of the manipulation is switched from harming the user to being user-friendly. For example, instead of highlighting the option that harms the user, the user-friendly option is highlighted.

How the Symbiosis Works

The symbiosis view connects dark patterns to bright alternatives

Dark Patterns match Bright Patterns

In the symbiosis view, each dark high/meso level pattern is paired with at least one matching bright pattern.

This view does not include low-level patterns, as these are implementation details. Refer to the related meso or high-level patterns for bright low-level alternatives.

Learn more about pattern levels in the pattern levels explainer.

Alternatives

Go into detail for each pair to see how a manipulative dark pattern can be replaced by an ethical bright pattern.

For that click on a pair in the symbiosis view to open its detail page. There you get a guide on how to apply the bright pattern and you can compare the bright pattern directly to the dark pattern.
