Privacy of practicing high-level martial artists (BJJ, CI)

Continuing my somewhat lazy “ethnographic” study of Brazilian Jiu Jitsu, an interesting occurrence happened the other day that illustrates something interesting about BJJ that is reflective of privacy as contextual integrity.

Spencer (2016) has accounted for the changes in martial arts culture, and especially Brazilian Jiu Jitsu, due to the proliferation of video on-line. Social media is now a major vector for the skill acquisition in BJJ. It is also, in my gym, part of the social experience. A few dedicated accounts on social media platforms that share images and video from the practice. There is a group chat where gym members cheer each other on, share BJJ culture (memes, tips), and communicate with the instructors.

Several members have been taking pictures and videos of others in practice and sharing them to the group chat. These are generally met with enthusiastic acclaim and acceptance. The instructors have also been inviting in very experienced (black belt) players for one-off classes. These classes are opportunities for the less experienced folks to see another perspective on the game. Because it is a complex sport, there are a wide variety of styles and in general it is exciting and beneficial to see moves and attitudes of masters besides the ones we normally train with.

After some videos of a new guest instructor were posted to the group chat, one of the permanent instructors (“A”) asked not to do this:

A: “As a general rule of etiquette, you need permission from a black belt and esp if two black belts are rolling to record them training, be it drilling not [sic] rolling live.”

A: “Whether you post it somewhere or not, you need permission from both to record then [sic] training.”

B: “Heard”

C: “That’s totally fine by me, but im not really sure why…?

B: “I’m thinking it’s a respect thing.”

A: “Black belt may not want footage of him rolling or training. as a general rule if two black belts are training together it’s not to be recorded unless expressly asked. if they’re teaching, that’s how they pay their bills so you need permission to record them teaching. So either way, you need permission to record a black belt.”

A: “I’m just clarifying for everyone in class on etiquette, and for visiting other schools. Unless told by X, Y, [other gym staff], etc., or given permission at a school you’re visiting, you’re not to record black belts and visiting upper belts while rolling and potentially even just regular training or class. Some schools take it very seriously.”

C: “OK! Totally fine!”

D: “[thumbs up emoji] gots it :)”

D: “totally makes sense”

A few observations on this exchange.

First, there is the intriguing point that for martial arts black belts teaching, their instruction is part of their livelihood. The knowledge of the expert martial arts practitioner is hard-earned and valuable “intellectual property”, and it is exchanged through being observed. Training at a gym with high-rank players is a privilege that lower ranks pay for. The use of video recording has changed the economy of martial arts training. This has in many ways opened up the sport; it also opens up potential opportunities for the black belt in producing training videos.

Second, this is framed as etiquette, not as a legal obligation. I’m not sure what the law would say about recordings in this case. It’s interesting that as a point of etiquette, it applies only to videos of high belt players. Recording low belt players doesn’t seem to be a problem according to the agreement in the discussion. (I personally have asked not to be recorded at one point at the gym when an instructor explicitly asked to be recorded in order to create demo videos. This was out of embarrassment at my own poor skills; I was also feeling badly because I was injured at the time. This sort of consideration does not, it seem, currently operate as privacy etiquette within the BJJ community. Perhaps these norms are currently being negotiated or are otherwise in flux.)

Third, there is a sense in which high rank in BJJ comes with authority and privileges that do not require any justification. The “trainings are livelihood” argument does apply directly to general practice roles; the argument is not airtight. There is something else about the authority and gravitas of the black belt that is being preserved here. There is a sense of earned respect. Somehow this translates into a different form of privacy (information flow) norm.

social structure and the private sector

The Human Cell

Academic social scientists leaning towards the public intellectual end of the spectrum love to talk about social norms.

This is perhaps motivated by the fact that these intellectual figures are prominent in the public sphere. The public sphere is where these norms are supposed to solidify, and these intellectuals would like to emphasize their own importance.

I don’t exclude myself from this category of persons. A lot of my work has been about social norms and technology design (Benthall, 2014; Benthall, Gürses and Nissenbaum, 2017)

But I also work in the private sector, and it’s striking how differently things look from that perspective. It’s natural for academics who participate more in the public sphere than the private sector to be biased in their view of social structure. From the perspective of being able to accurately understand what’s going on, you have to think about both at once.

That’s challenging for a lot of reasons, one of which is that the private sector is a lot less transparent than the public sphere. In general the internals of actors in the private sector are not open to the scrutiny of commentariat onlookers. Information is one of the many resources traded in pairwise interactions; when it is divulged, it is divulged strategically, introducing bias. So it’s hard to get a general picture of the private sector, even though accounts for a much larger proportion of the social structure that’s available than the public sphere. In other words, public spheres are highly over-represented in analysis of social structure due to the available of public data about them. That is worrisome from an analytic perspective.

It’s well worth making the point that the public/private dichotomy is problematic. Contextual integrity theory (Nissenbaum, 2009) argues that modern society is differentiated among many distinct spheres, each bound by its own social norms. Nissenbaum actually has a quite different notion of norm formation from, say, Habermas. For Nissenbaum, norms evolve over social history, but may be implicit. Contrast this with Habermas’s view that norms are the result of communicative rationality, which is an explicit and linguistically mediated process. The public sphere is a big deal for Habermas. Nissenbaum, a scholar of privacy, reject’s the idea of the ‘public sphere’ simpliciter. Rather, social spheres self-regulate and privacy, which she defines as appropriate information flow, is maintained when information flows according to these multiple self-regulatory regimes.

I believe Nissenbaum is correct on this point of societal differentiation and norm formation. This nuanced understanding of privacy as the differentiated management of information flow challenges any simplistic notion of the public sphere. Does it challenge a simplistic notion of the private sector?

Naturally, the private sector doesn’t exist in a vacuum. In the modern economy, companies are accountable to the law, especially contract law. They have to pay their taxes. They have to deal with public relations and are regulated as to how they manage information flows internally. Employees can sue their employers, etc. So just as the ‘public sphere’ doesn’t permit a total free-for-all of information flow (some kinds of information flow in public are against social norms!), so too does the ‘private sector’ not involve complete secrecy from the public.

As a hypothesis, we can posit that what makes the private sector different is that the relevant social structures are less open in their relations with each other than they are in the public sphere. We can imagine an autonomous social entity like a biological cell. Internally it may have a lot of interesting structure and organelles. Its membrane prevents this complexity leaking out into the aether, or plasma, or whatever it is that human cells float around in. Indeed, this membrane is necessary for the proper functioning of the organelles, which in turn allows the cell to interact properly with other cells to form a larger organism. Echoes of Francisco Varela.

It’s interesting that this may actually be a quantifiable difference. One way of modeling the difference between the internal and external-facing complexity of an entity is using information theory. The more complex internal state of the entity has higher entropy than the membrane. The fact that the membrane causally mediates interactions between the internals and the environment prevents information flow between them; this is captured by the Data Processing Inequality. The lack of information flow between the system internals and externals is quantified as lower mutual information between the two domains. At zero mutual information, the two domains are statistically independent of each other.

I haven’t worked out all the implications of this.

Contextual Integrity as a field

There was a nice small gathering of nearby researchers (and one important call-in) working on Contextual Integrity at Princeton’s CITP today. It was a nice opportunity to share what we’ve been working on and make plans for the future.

There was a really nice range of different contributions: systems engineering for privacy policy enforcement, empirical survey work testing contextualized privacy expectations, a proposal for a participatory design approach to identifying privacy norms in marginalized communities, a qualitative study on how children understand privacy, and an analysis of the privacy implications of the Cybersecurity Information Sharing Act, among other work.

What was great is that everybody was on the same page about what we were after: getting a better understanding of what privacy really is, so that we can design between policies, educational tools, and technologies that preserve it. For one reason or another, the people in the room had been attracted to Contextual Integrity. Many of us have reservations about the theory in one way or another, but we all see its value and potential.

One note of consensus was that we should try to organize a workshop dedicated specifically to Contextual Integrity, and widening what we accomplished today to bring in more researchers. Today’s meeting was a convenience sample, leaving out a lot of important perspectives.

Another interesting thing that happened today was a general acknowledgment that Contextual Integrity is not a static framework. As a theory, it is subject to change as scholars critique and contribute to it through their empirical and theoretical work. A few of us are excited about the possibility of a Contextual Integrity 2.0, extending the original theory to fill theoretical gaps that have been identified in it.

I’d articulate the aspiration of the meeting today as being about letting Contextual Integrity grow from being a framework into a field–a community of people working together to cultivate something, in this case, a kind of knowledge.
