Weighing the Value of Privacy

An anonymous reader writes "A new study from HP Labs shows that the reluctance of individuals to reveal private information (or how much money they would demand to do so), depends on how far they perceive themselves to be from the norm. For example, those who think they are overweight ask a higher price to step on a scale in front of their peers, than those of average weight. From the article: 'How and why people decide to transition their information from the private to the public sphere is poorly understood. To address this puzzle, we conducted a reverse second-price auction to identify the monetary value of private information to individuals and how that value is set. Our results demonstrate that deviance, whether perceived or actual, from the group's average asymmetrically impacts the price demanded to reveal private information.'"

      That is a little harsh. See, psychological research tends to go in small steps. First, someone develops an IQ test. Then, someone finds out that people with higher IQ tend to be more successful in their career later. Suprise? News? Of course not. But then this phenomenon is investigated in more and more detail, and it turns out that an IQ test is the singe most successful criterion to predict career success. And so it makes sense for companies to do IQ tests when selecting new employees. Then you can start optimizing IQ tests for specific job profiles. Etc.

      Of course, this is not a very revolutionary paper. But it probably does contain a new idea, namely to measure the value of privacy in monetary terms.

      For this reason, if no other, broadcast of such findings may be at least educational and may provide some small measure of understanding. Not necessarily a bad thing.

      As to the conditioning aspect, my experience is that, although social conditioning does genuinely occur, it will only take where there is already a predisposition to that set of judgements, on a broad social level. Conditioning reinforces beliefs and fears but tends not to be able to create new ones. Unless you are very good at it and can conflate the new belief with one which is already held. Piggy-backing it on the emotional force of the old one.

      This is also becoming less uncommon with increased sophistication in manipulating communication coupled with an increased capacity to reach larger audiences.

      Humans are social animals and tend to cluster into groups. The formation of groups involves the creation of memes which define the nature of that group. Norms and margins are then set around the degree of closeness to or divergence from those memes.

      Slashdot subscribers hold certain patterns as central to our presence here. These may be very different to those of three year olds in a kindergarten (although maybe not - you tell me).

      The degree to which we conform to the norms is a direct measure of our conformance with the memes of that social group and by extension a reflection of to what degree we belong to that structure, are accepted by it or even our acceptance of it.

      To diverge by more than, say, two standard deviations from the mean, begins to put us into the marginal area.

      A desire to be a member of the group, under those circumstances, can bring with it a tension regarding that association. If I interpret my membership as some sort of moral imperative, and if I am predisposed to self criticism, then, yes, I may feel embarrassed by my lack of conformity.

      On the other hand, if I am aware of the necessary diversity of a statistical distribution, I may, instead, revel in my individual differences, realising that I am representing a boundary on that group.

      All conditions across the spectrum of a distribution will have psychological baggage associated with it. However, the further we move into the margins, the less we experience support from the group - as a part of it rather than as, say compassion, sympathy or even, to take the other end of things, adoration as the other.

      I don't see these things as representing a false ideal. Rather an accepted ideal but limited to the context of a given group.

In fact, they need more than immunity from invasion: they need time for reflection, time when they are not in co-operation with others or distracted by other commitments.

Especially during periods where certain opinions are unpopular, it is important to have strong protections of privacy because the ability to communicate ideas to trusted friends (and in so doing, refine & strengthen your arguments) without fear of being targetted by public/government scrutiny is (IMHO) a very important part of the democratic process.

Next if you ask them how many movie theatres are there in Russia - you will find their answer strongly affected by the number 1275. This is called "anchoring." Anchoring may have reflected why people asked between $4 and $19. They were looking at a 20% to 80 percent increase in that session's earnings and so looks "big" to the $25 anchor.

    The experiment was fully explained to the subjects and a consent form was signed. Subjects were free to leave or not participate.

    This is even more problematic. Once you have committed to coming would you just walk out of the whole situation ? Has the time that you spent thinking about this before you came played a role in whether you stay or leave?

    This distance from a perceived ideal is far more important than privacy attitudes, how well one knows the group, or actual deviance from an objective mean.
