(Somebody on Quora asked, What is the social justification of privacy? adding, I am trying to ask about why individual privacy is important to society. Obviously it is preferable to individuals for a variety of reasons. But society seems to gain more from transparency. So, rather than leave my answer buried there, I decided to share it here as well.)

Society is comprised of individuals, and thick with practices and customs that respect individual needs. Privacy is one of those. Only those of us who live naked outdoors without clothing and shelter can do without privacy. The rest of us all have ways of expressing and guarding spaces we call “private” — and that others respect as well.

Private spaces are virtual as well as physical. Society would not exist without well-established norms for expressing and respecting each others’ boundaries. “Good fences make good neighbors,” says Robert Frost.

One would hardly ask to justify the need for privacy before the Internet came along; but it is a question now because the virtual world, like nature in the physical one, doesn’t come with privacy. By nature we are naked in both. The difference is that we’ve had many millennia to work out privacy in the physical world, and approximately two decades to do the same in the virtual one. That’s not enough time.

In the physical world we get privacy from clothing and shelter, plus respect for each others’ boundaries, which are established by mutual understandings of what’s private and what’s not. All of these are both complex and subtle. Clothing, for example, customarily covers what we (in English vernacular at least) call our “privates,” but also allow us selectively to expose parts of our bodies, in various ways and degrees, depending on social setting, weather and other conditions. Privacy in our sheltered spaces is also modulated by windows, doors, shutters, locks, blinds and curtains. How these signal intentions differs by culture and setting, but within each the signals are well understood, and boundaries are respected. Some of these are expressed in law as well as custom. In sum they comprise civilized life.

Yet life online is not yet civilized. We still lack sufficient means for expressing and guarding private spaces, for putting up boundaries, for signaling intentions to each other, and for signaling back respect for those signals. In the absence of those we also lack sufficient custom and law. Worse, laws created in the physical world do not all comprehend a virtual one in which all of us, everywhere in the world, are by design zero distance apart — and at costs that yearn toward zero as well. This is still very new to human experience.

In the absence of restricting customs and laws it is easy for those with the power to penetrate our private spaces (such as our browsers and email clients) to do so. This is why our private spaces online today are infected with tracking files that report our activities back to others we have never met and don’t know. These practices would never be sanctioned in the physical world, but in the uncivilized virtual world they are easy to rationalize: Hey, it’s easy to do, everybody does it, it’s normative now, transparency is a Good Thing, it helps fund “free” sites and services, nobody is really harmed, and so on.

But it’s not okay. Just because something can be done doesn’t mean it should be done, or that it’s the right thing to do. Nor is it right because it is, for now, normative, or because everybody seems to put up with it. The only reason people continue to put up with it is because they have little choice — so far.

Study after study show that people are highly concerned about their privacy online, and vexed by their limited ability to do anything about its absence. For example —

• Pew reports that “93% of adults say that being in control of who can get information about them is important,” that “90% say that controlling what information is collected about them is important,” that 93% “also value having the ability to share confidential matters with another trusted person,” that “88% say it is important that they not have someone watch or listen to them without their permission,” and that 63% “feel it is important to be able to “go around in public without always being identified.”
• Ipsos, on behalf of TRUSTe, reports that “92% of U.S. Internet users worry about their privacy online,” that “91% of U.S. Internet users say they avoid companies that do not protect their privacy,” “22% don’t trust anyone to protect their online privacy,” that “45% think online privacy is more important than national security,” that 91% “avoid doing business with companies who I do not believe protect my privacy online,” that “77% have moderated their online activity in the last year due to privacy concerns,” and that, in sum, “Consumers want transparency, notice and choice in exchange for trust.”
• Customer Commons reports that “A large percentage of individuals employ artful dodges to avoid giving out requested personal information online when they believe at least some of that information is not required.” Specifically, “Only 8.45% of respondents reported that they always accurately disclose personal information that is requested of them. The remaining 91.55% reported that they are less than fully disclosing.”
• The Annenberg School for Communications at the University of Pennsylvania reports that “a majority of Americans are resigned to giving up their data—and that is why many appear to be engaging in tradeoffs.” Specifically, “91% disagree (77% of them strongly) that ‘If companies give me a discount, it is a fair exchange for them to collect information about me without my knowing.'” And “71% disagree (53% of them strongly) that ‘It’s fair for an online or physical store to monitor what I’m doing online when I’m there, in exchange for letting me use the store’s wireless internet, or Wi-Fi, without charge.'”

There are both policy and market responses to these findings. On the policy side, Europe has laws protecting personal data that go back to the Data Protection Directive of 1995. Australia has similar laws going back to 1988. On the market side, Apple now has a strong pro-privacy stance, posted Privacy – Apple, taking the form an open letter to the world from CEO Tim Cook. One excerpt:

“Our business model is very straightforward: We sell great products. We don’t build a profile based on your email content or web browsing habits to sell to advertisers. We don’t ‘monetize’ the information you store on your iPhone or in iCloud. And we don’t read your email or your messages to get information to market to you. Our software and services are designed to make our devices better. Plain and simple.”

But we also need tools that serve us as personally as do our own clothes. And we’ll get them. The collection of developers listed here by ProjectVRM are all working on tools that give individuals ways of operating privately in the networked world. The most successful of those today are the ad and tracking blockers listed under Privacy Protection. According to the latest PageFair/Adobe study, the population of persons blocking ads online passed 200 million in May of 2015, with a 42% annual increase in the U.S. and an 82% rate in the U.K. alone.

These tools create and guard private spaces in our online lives by giving us ways to set boundaries and exclude unwanted intrusions. These are primitive systems, so far, but they do work and are sure to evolve. As they do, expect the online world to become as civilized as the offline one — eventually.
