-<h3 id="consent">Ask users for meaningful consent</h3>
+<h3 id="user-intent">Design for user intent</h3>
 
 In the context of fulfilling a user need,
 a web page may want to make use of a feature
 that has the potential to cause harm.
-Features that have this potential for harm should be designed such that people can give
-[meaningful consent](https://www.w3.org/2001/tag/doc/ethical-web-principles/#control) for that feature to be used,
-and that they can refuse consent effectively.
-
-In order to give *meaningful consent*, the user must:
-- **understand** what permission they may choose whether to grant the web page
-- be able to choose to give or refuse that permission **effectively**.
-
-If a feature is powerful enough to require user consent,
-but it's impossible to explain to a typical user what they are consenting to,
-that's a signal that you may need to reconsider the design of the feature.
-
-If a permission prompt is shown,
-and the user doesn't grant permission,
-the Web page should not be able to do anything
-that the user believes they have refused consent for.
-
-By asking for consent,
-we can inform the user of what capabilities the web page does or doesn't have,
-reinforcing their confidence that <a href="#safe-to-browse">the web is safe</a>.
-However, the <a href="#priority-of-constituencies">user benefit</a>
-of a new feature must justify the additional burden on users
-to decide whether to grant permission for each feature
-whenever it's requested by a Web page.
+Using such a feature should only be possible
+if the user's expectation matches the feature's consequences
+(e.g., personal information used, state changed).
+
+Design your API so its behavior matches what people intend and expect.
+Then, in the best case, people don't need to get involved in allowing API access
+and thus can't make decisions they regret later. 
+Only ask the user for confirmation in exceptional circumstances.
+If a capability can be easily reverted or causes only mild annoyance without the chance for permanent harm, 
+afford users an option to stop capability access instead.
+
+<p class="example">
+For example, web pages don't need to ask for permission to play sounds.
+It is easy to stop audio output if a site is found to be abusing it
+and browsers have a number of mechanisms for doing just that.
+Similarly, PWAs wanting to use [Window Control Overlay](https://wicg.github.io/window-controls-overlay/) don't need to ask for permission,
+as the user simply toggles this mode on when they need it.

+
+<h4 id="user-decisions">Help users make good decisions</h4>
+
+Empower good decision-making by limiting risk at the API level and
+providing clarity, context, and user control.
+Asking for user approval has been a common way to handle remaining risk.
+However, most people can't make good decisions on
+many of the questions they're asked  
+because they lack crucial context and information.  
+Being confronted with difficult or annoying questions leads
+to decision fatigue, habitual responses,
+annoyance from frequent interruptions, and regrettable decisions.
+
+When user involvement is unavoidable,
+empower users to make good decisions.
+Use these principles:
+
+* **Limit the consequences from a bad decision by addressing risk at the API level first.**
+    Do not ask users questions where a "bad" decision can lead to severe consequences,
+    like a compromised device or serious personal data disclosure.
+* **Provide constant feedback about persistent decisions.**   
+    If users' decisions last longer than the current session,
+    user agents should remind users that their past decision still applies.
+    Provide a way to retract any ongoing permission,
+    including APIs to inform sites of the change in status.
+* **Ask questions people can understand.**
+    The associated risks should be obvious from the question for a typical user
+    and be directly connected to the feature's or API's utility.
+    For example, this usually means we can't ask permission to accept fingerprinting risks,
+    as they are subtle, technical, and commonly have nothing to do with the capability itself.
+* **Provide sufficient context.**
+    People need to easily understand who they're dealing with,
+    what the decision is about, and how the website will use any information they might share.
+* **Let people make decisions when *they* are ready.**
+    Websites should not be able to force the decision moment on the user,
+    while they're trying to do something else.
+    Instead, people should be able to choose the decision moment,
+    for example by clicking on a dedicated button like for the file chooser.
+
+If you can't adhere to all of the above principles,
+that is likely an indication that asking the user isn't the right approach.
+Instead, change the feature or API to address any remaining risk.
 
 In your specification, the [=request permission to use=] and [=prompt the user to choose=] algorithms from [[permissions]] are good ways to ask for consent.
 
+If you ask a user to make a decision and they say no, the website shouldn't be able to do anything the user believes they just refused access to. 
+
 Refusal is most effective if the site cannot
 distinguish refusal from other, common situations.
 This can make it more difficult for a site to
 pressure users to grant consent.
 
-<p class="example">
-For example,
-the [Geolocation API](https://www.w3.org/TR/geolocation-API/)
-grants access to a user's location.
-This can help users in some contexts,
-like a mapping application,
-but may be dangerous to some users in other contexts -
-especially if used without the user's knowledge.
-So that the user may decide whether their location may be used by a Web page,
-a permission prompt should be shown to the user asking whether to grant location access.
-If the user refuses permission,
-no location information is available to the Web page.
