## Require an active choice when no safe default fits most people

ID: MHC-D-RESEARCH-9216 · Version: 0.1.0 · Kind: principle

A default is convenient only when choosing for people by inaction is defensible.

### Use when

- You design a form, product, team process or recurring workflow and are about to preselect an option with meaningful consequences for other people.

### Avoid when

- Active choice has its own attention cost and can be harmful when users lack information or the decision is needlessly complex. Do not remove well-justified safety defaults merely to appear neutral, and do not use transparency as permission for manipulative friction.

### Explanation

If reasonable people may want materially different outcomes and you cannot justify one preset as a safe fit, require a small explicit choice instead. Keep the alternatives understandable and proportionate to the stakes. If you do use a default, say what is preselected and make changing it practical; current transparency evidence does not support the assumption that disclosure necessarily destroys the behavioral effect.

### Checklist

- Would different reasonable users want different outcomes here?
- Can the preset create meaningful cost, privacy, risk or commitment for somebody who overlooks it?
- Can I justify one default from the chooser's interests rather than my convenience?
- If not, can I ask for one clear explicit choice?
- If a default remains, is it visible and easy to change?

### Example

Instead of silently enrolling every teammate in a high-notification mode, ask once between focused and high-alert modes when both are legitimate working preferences, then let the person change it later.

### Check

The design can explain why a default is appropriate—or it replaces the preset with an explicit choice when that justification fails.

### Limits

- Active choice has its own attention cost and can be harmful when users lack information or the decision is needlessly complex. Do not remove well-justified safety defaults merely to appear neutral, and do not use transparency as permission for manipulative friction.

### Evidence and sources

- supports: A review of default-nudge design argues that active choosing can reduce some autonomy and welfare problems created by inappropriate defaults, especially when a choice architect cannot safely presume one option fits the chooser. — RS-952B74ACA0E064D3EA14. Active choice also imposes attention and decision costs; it is not automatically better for simple, low-risk or strongly preference-aligned decisions. (Abstract, ethical design taxonomy and conclusions)
- supports: A 2025 meta-analysis comparing transparent with covert nudges found no evidence that transparency generally weakens behavioral outcomes and reported a positive pooled transparency effect on behavior, but the evidence was dominated by online or laboratory default studies. — RS-D09F4B11869DC485DF27. Only two included studies were field studies and 88% of effects involved defaults, which sharply limits generalization to other nudge types and real-world settings. (Abstract and repository summary)
