Feedforward Ambiguity and Unambiguous Choices

How to Apply

Label buttons with clear action results, e.g., “Save and send email” instead of “Continue”
Add a short, specific explanation under each option describing what will happen next

Dark Pattern

Feedforward Ambiguity

It creates a mismatch between the information given and the actions available, leading users to outcomes they did not anticipate.

Feedforward Ambiguity subverts the user’s expectation that their choice will be likely to result in an action they can predict, instead providing a discrepancy between information and actions available to users that results in an outcome that is different from what the user expects.

Unambiguous Choices

Open →

Design options with simple, clear language so users know exactly what each action will do.

Design options in for example forms and pop-ups with simple, clear language so users know exactly what each action will do. This eliminates confusing or misleading options and supports informed decision making.

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.
