Hi Alan, I don't mean to pile on or seem confrontational...

But for those of us who have a background in privacy theory and scholarship, "show us the harms" comes up often, and I don't think it's exactly the right question.

Privacy implications/intrusions are often emotional, intangible and subject to considerable variation amongst individuals. I think the Berkeley survey write-up makes a number of key points: at least in the US, the FTC has had to police privacy issues on a piecemeal basis, and the increasing collection of data about the web-surfing public coupled with problems in protecting and in some cases exploiting that information (cite to settlements/actions) means we really need an effective way to allow users to signal that they don't want this collection and subsequent implications (with some narrow common-sense exceptions). It certainly is complicated in the bigger, global picture ... and I'd like to think we we can design something that effectively does that. And despite defaults or not, many of us will be educating users about these tools (and how to grant exceptions and what that means) when the spec gets adopted.

best, Joe

So I want to applaud your effort to help provide additional information and to facilitate a dialog. That said, I want to make sure I understand your thinking here – or at least help clarify some of the distinctions you may be drawing.

For example, in your scenario where "an actor that causes harm to a consumer." Is that not also possible in a first party context? Does the first party not have both "the means", "the access" and at least potentially, the ability to take the  "action" that causes the harms you lay out? (e.g., "Publication, a less favorable offer, denial of a benefit, or termination of employment. Last, a particular harm that is inflicted. The harm might be physical, psychological, or economic.")

The actor might, for example, be an authorized employee, malicious employee, competitor, acquirer, hacker, or government agency. Second, a means of access that enables the actor to use tracking data. The data might be voluntarily transferred, sold, stolen, misplaced, or accidentally distributed. Third, an action that harms the consumer. The action could be, for example, publication, a less favorable offer, denial of a benefit, or termination of employment. Last, a particular harm that is inflicted. The harm might be physical, psychological, or economic.

To ex- emplify ourthinking, here is one commonly considered scenario: A hacker (actor) breaksinto a tracking company (means of access) and publishes its tracking information (action), causing some embarrassing fact about the consumer to become known and inflicting emotional distress (harm).9

If a first-party website is untrustworthy, users may decline to visit it. But, since users are unaware of the very existence of many third-party websites, they cannot reward responsible sites and penalize irresponsible sites.10"
