Nice For a Price: esteem as a social incentive

Daily, enormous numbers of people interact in digitally mediated social groups. They usually behave prosocially, that is, they generally play nice with each other, often cooperate and sometimes even collaborate in the creation of a social good. As a result there's a lot of discussion around the sorts of stable social contracts groups can coordinate on; how new tools and designs for getting together impact and are impacted by these possible social contracts; and what sorts of incentives or motivations individuals have to play nice in the first place given that cooperating isn’t necessarily as easy, cheap or materially profitable as being a jerk.

This (way too long) post is all about motivations to join a group and act collectively. It’s the second post in a series (first one) trying to show that the recent focus on the deeply social or other-regarding nature of social and collective action groups online is too one-sided, simplistic and, frankly, ideological. Certainly we’re social animals with frequently benevolent motivations. But that doesn’t mean that we’ve no self-centered, broadly (as opposed to narrowly or materially) rational motivations. Extrinsic incentives, which we scheme to “maximize” in our limited way, abound in social situations. However, they’re mostly non-material things like esteem – the positive evaluation of your actions by the norm-based standards of your group – and status – deferential position in a social group. These are real motivations. Even Yochai Benkler, a genuine web utopianist, mentions them briefly in his Wealth of Networks. He says in passing that they’re part of our real motivational repertoire. But generally these issues are treated as either a dirty secret or beside the point. They’re neither. We need to really look at how these inescapable self-regarding motivations can help us be more prosocial and not just blame them when we’re antisocial.

Since it’s the most completely worked out account of the effects of social functionality on group creation and maintenance, I’ll focus on Clay Shirky’s excellent Here Comes Everybody. Smart as he is, I’m sure he understands the point about the value of broadly instrumental motivations for prosocial behavior. But the hero of his book is the genuine prosociality of humans freed from the limitations of “real world” organizational overhead by digital social functionality. And though he addresses self-serving, antisocial behavior like disinhibition and free-riding, he avoids talk of self-interested, extrinsic motivations for collective action almost entirely, focusing instead on intrinsic motivations such as vanity, self-esteem, true interest in the public good and simple innate pro-sociality. I agree with most of his conclusions, I just think he left out a huge factor that should inform thinking and design around online sociality.

Two Motivation Problems

There are two big problems of motivation here that are conceptually, but probably not practically, separable. First, there’s the motivation connected to the collective good some group’s trying to bring about, say, a high-quality, UGC encyclopedia like Wikipedia. Second, there’s the motivation to play nice, to make your contribution to the collective good you value in a way that the group approves of, like sticking to citable facts as opposed to stating an opinion when adding to a Wikipedia entry.

Riffing on a very useful distinction made by Clay Shirky in his latest book, we can divide our motivations between the group’s promise, whatever collective good or goal it’s trying to achieve, and the bargain, or the social contract within or through which the goal is to be achieved (he also distinguishes the tools, or the actual functionality the group employs to achieve the promise, but that’s for a different post). For Shirky, if you care about the goal embedded in the promise – e.g. collectively create a quality, UGC encyclopedia – and consider it actually attainable as it’s implicitly “stated,” then you’ll be motivated to contribute. Indeed, Shirky explicitly considers motivation only in regard to the promise: “The promise is the essential piece, the thing that convinces a potential user to become an actual user.”

In practice, it’s not so easy to separate the promise from the bargain. But in theory we can say that the promise is normatively degenerate. That is, you can achieve the promise through a variety of bargains. Although the details of the bargain have a huge impact on the viability of the promise, you could theoretically develop a quality, UGC encyclopedia without the exact same contributor/editor structure or implicit/explicit rule sets operating on Wikipedia. Again, they’re theoretically separable but probably not practically separable; it’s most likely the case that people don’t even know they “have” a goal or value the content of the promise until it’s articulated to them via the specific implicit promise couched in terms of some tentative, operating bargain. That is, the actual “articulation” of the promise in the context of the bargain probably creates people’s desire to reach the collective goal as much as it meets it. Also, bargains tend to be continually re-negotiated during the process of actively pursuing the promise.

Shirky would undoubtedly disagree, but it seems like the bargain impacts overall motivation in addition to the motivation arising from the promise. If you value the promise and think this group’s specific bargain is a decent way to achieve it, then you’ll be motivated to join this specific group or contribute to this particular collective good. But if the social environment in which you can contribute to your genuinely desired social good blows, then you’ll likely have to be a lot more motivated by that good to stick around. Similarly, if you're only moderately motivated by the promise, but the bargain offers something exciting in itself – say, the public adoration of your peers – then that might be enough to get you contribute when you otherwise wouldn't. Clearly, the bargain impacts overall motivation, positively or negatively, though some initial interest in the collective goal is probably necessary in the first place.

Anyway, one of the big arguments of Shirky’s book is that toady’s social functionality lowers the cost of contributing and collaborating to such a degree that people motivated by the same promise or goal – latent groups to use Shirky’s Mancur Olson-inspired term – can actually get together to do something about it. Even relatively weak goal motivation is no longer blocked from actually resulting in action since the overhead associated with coordination has dropped so dramatically; thanks to social functionality like wikis, blogs, tagging, cell phones, etc., it’s really “easy” to get dispersed people together to focus on some collectively defined good.

However, since the promise is “normatively degenerate,” i.e. can be achieved by means of a number of distinct social contracts or bargains, we still need to consider people’s motivation to comply with a specific bargain given the goal. What would make people choose one Bargain over another? Does the nature of the Bargain do anything to the overall motivation to contribute or cooperate? To answer these, we first need to say what a Bargain is. Fudging a little, we can say that Bargains, as little social contracts of sorts, are collections of norms

Why Comply?

Social norms are the implicit (but they can become explicit like some laws or codes) interaction rules that keep social groups from deteriorating into antisocial free-for-alls. They turn potentially state-of-nature, every-man-for-himself interactions into coordination games. Humans are social animals, but that doesn’t mean we always play nice. If it did, we’d rarely see any groups fall apart. Everybody would play nice by their group’s standards. As it is, though, we see a lot of antisocial, anti-normative behavior in contexts in which prosocial norms would be appropriate, particularly online. This suggests that we have a conditional preference for following norms. If the conditions are met, we play by the norms, otherwise it’s a melee. Obviously, the conditions under which we can generally induce a preference for social norm following on the part of most users should impact our designs for social spaces online and elsewhere.

Just to solidify everything, I’ll borrow (with slight fudging/modification) Cristina Bicchieri’s idea that there are three types of conditions which have to be met for someone to prefer following a norm in a given situation.

  1. Empirical Condition: Do you expect the norm to be observed by most people in this sort of situation?
  2. Normative Condition: Do you believe that most people expect or prefer you to follow it in this sort of situation?
  3. Motivational Conditions: There are several of these and they relate to your reasons for complying given the truth of 1 and 2 above.
  • Fear: Is your compliance solely based on fear of negative sanctions for non-compliance?
  • Esteem: Is your compliance based on positive sanctions like praise and esteem?
  • Reasonableness/Internalization: Is your compliance based on your assessment of the reasonableness of the norm or possibly on a non-reflective, conditioned expectation?

The first two are necessary existence conditions for the norm. If neither are met, even if there's ostensibly a norm in place you won’t follow it because either you don’t think everybody else will or you feel it’s not really expected of you. In any given situation the norm may not be salient, and thus people might not know they should be following it. So, designs for spaces in which you want users to coordinate on a cooperation-inducing social contract should include provision for making norms salient (e.g., user-rating of UGC, contribution sorting by quality, etc.). But salience isn’t really what interests me here. Let's look at the Motivational conditions, which are about the reasons for personal compliance provided the Empirical and Normative conditions are met. If you think we just have a basic preference to do as others do regardless of our relationship to them, then consider these supplementary.

Compliance out of fear of negative sanctions, from frowns to finger wagging to expulsion from the group, can be very powerful. Often people play by the rules because of perceived threat of force, even if it’s just social force in the form of conventionalized displays of displeasure (reprimands from admins, poorly rated UGC, banishment, etc.). This is the most widely recognized motivation in the literature. Clearly, it only operates under conditions of at least partial transparency or incomplete anonymity and some sort of publicity or public availability of contributions.

Viewing the norm as reasonable or maybe even internalizing it, renders compliance largely non-reflective. You don’t act out of fear or positive incentive, you just obey the norm. This motivation doesn’t have any observation conditions on the situation; you’d obey the norm in totally anonymous interactions.

Esteem motivated compliance is a little different from the other two. In this cases you obey because obeying results in a personal gain or good in addition to whatever motivations you take to be intrinsic (e.g. general preference for conformity). You get something of value from others – esteem – for acting appropriately or contributing at a high, group-defined standard. The esteem motive is related to the fear motive, particularly if we consider disesteem a negative sanction. And like the fear motive it requires limited anonymity and publicity of contributions.

If esteem is a sought after item in limited supply, then it can add to the overall motivation one has for contributing to the larger social good defined by the group’s Promise. If complying with a social contract and contributing at a high level relative to the group’s norms can generate esteem, then people already motivated by the group’s goal have additional motivation to work. They have been significantly incentivized beyond the presumably prosocial incentive of the collective good.

Even if the collective good is materially negligible or even costly to the individual, the esteem motivation associated with group norm compliance can incentivize behavior to bring about the collective good (provided overall motivation can be the aggregate of promise-based and bargain-based motivations). Basically, implementing the social contract in such a way that esteem can be accumulated (limited anonymity and institutionalized feedback channels, for example) can make selfish jerks work prosocially. However, it also makes people for whom the collective good is genuinely motivating even more motivated.

Obviously, there is considerable space for trouble here. Unethical, mistaken and outmoded norms can easily be perpetuated by esteem motivated compliance. Agreed. Our task as designers and theorists in this space is to figure out how these mechanisms work and whether or not they can be reliably used for prosocial ends. That's why I think the bias for consideration of intrinsic and clearly prosocial motives only is shortsighted. Esteem and other extrinsic non-material motivations operate in all social groups. Unless we face our less social, selfish selves and try to understand how they operate, we can't even begin to make design decisions that will allow us to channel this ignoble element in our character for proscocial – or at least not antisocial – ends.

A Note On Near Anonymity, Limited Publicity and Esteem... skip at will

You might think that the near anonymity and volume of contributions of UGC creations like Wikipedia would destroy the esteem motivation: if next to nobody knows who you are and the volume of contributions mitigates the publicity any specific addition gets, then no esteem accumulates. I don’t think this is the case for several reasons.

For one thing, a study of handwashing habits in public restrooms in New York city showed that the mere presence of an anonymous stranger increased handwashing from 40% to 80%. (Munger, K. and S. J. Harris. 1989. “Effects of an Observer on Handwashing in a Public Restroom. Perceptual and Motor Skills 69(3):733-734.) The anonymity of the esteemer doesn’t seem to matter, but most importantly it doesn’t seem to matter that the esteem-seeker is anonymous as well. The mere fact that someone – anyone – could judge, the normatively charged public situation influences behavior regardless of anonymity.

Also, in many esteem situations, relative anonymity and obscurity actually heighten the potential for esteem. Basically, in many situations in which esteem is at issue, the potential esteemer judges not just the action but also the disposition. If calculation is obvious and the desire for recognition glaring, then you’re likely to give less esteem than if the estimable act occurred “for itself,” as it were. The public forum in which esteem is judged and the conditions under which credit is claimed ("I did this" or "I did this for the group") has an impact on this dispositional judgment. Too public and too obviously about you and not the good, and it might be showing off. But in conditions of limited publicity and partial anonymity your estimable act gives the impression that you’re doing it for its own sake. That is, an estimable act in situations where the probability of being seen and personally esteemed is relatively low (and all the other members knows this) renders much greater esteem if it is in fact seen and identified. In this situation, it looks like the act arose from a natural disposition and not esteem seeking. Near anonymity and limited visibility in some sense optimize esteem, in the words of Geoffrey Brennan and Philip Pettit.

Finally, esteem doesn’t have to circle back and add to our personal pool of accumulated esteem for us to feel it in some measure. That is, esteem attaching to your online identity, which nobody knows is really you, has its own reward. Indeed, we don’t always want the esteem we receive in one arena to mingle with (or be contaminated by) the personal esteem (or disesteem) earned in another. It’s a form of esteem management. Additionally, if Kai Spiekermann is right and the esteem others are willing to give often has less to do with what you’ve done than who you are, anonymity can level the playing field a bit and allow esteem to flow more freely than it would under more transparent conditions.

Playing Nice For the Wrong Reasons

We were sold the story of being mainly self-interested, mainly rational actors interacting in market places. And the internet has shown that we have all these social, empathetic relationships with deep, authentic motivations that are nothing to do with selling and spending.

Clay Shirky

The Observer, Sunday 15 February 2009


One hears this sentiment a lot these days, particularly from American web pundits. It sounds like a lingering echo of the utopianist strains of early web propaganda; it's a rhetorical move positioning the web as a signal force in a new flourishing of hierarchy-smashing communitarianism against the old alienating and atomizing intellectual myths of “maximization” and “rationality.” The idea's intellectual sources include the recent widely touted corrections (e.g. behavioral economics) of some of the excesses of neo-classical economics and possibly the U.S. sociological tradition stemming from “functionalism.”

Anyway, I agree wholeheartedly that we often cooperate or collaborate on the web out of more or less benevolent – if not truly altruistic – impulses. But it’s also obvious that “deep, authentic motivations” aren’t the only incentives for acting in, or even just joining, groups. Significant “shallow” and “inauthentic” motivations impact social behavior as well. “Ignoble” motivations like esteem accumulation and status achievement – which are both distinct from reputation – significantly impact people’s behavior in social settings. Indeed, much of the functionality on the social web already has an esteem function baked into its primary or legitimate function. As a simple example, posting reviews is as much about displaying expertise or simple likes and dislikes as it is about helping others choose. As a rule, people genuinely like to play nice and help each other. But they’ll play nicer and help more if you also let them compete for group defined goods that are neither “authentic” nor “deep.”

Sticking with Clay Shirky, in his latest book he recognizes that there is a place for some sorts of less than noble rewards online. For example, he considers “vanity” and reputational benefit to be valid motivations for contribution. But the mention of reputation notwithstanding, he focuses on intrinsic, non-material motivations like self-esteem, the desire to produce something good and the need for communion. What he doesn’t talk about are the powerful extrinsic, non-material motivations involving the attention of and positive evaluation by others in your group. You contribute partly for the esteem your contribution can get you. And this holds true even if the esteeming group is minuscule. Indeed, it’s often the case that the smaller the esteeming group, the more valuable the esteem (“selling out” after all is the trading of esteem for popularity).

If we’re honest with ourselves, it seems pretty clear that some of our motivations for social interaction on the web (and elsewhere) are self-interested, operate by some sort of market principles and are neither authentic nor empathetic. We engage in behavior that is intended to "maximize" some in demand good – esteem – relative to the costs we're willing to bear. Other things equal, the greater the potential esteem the more cost we're willing to bear. Esteem seeking definitely isn't ideally authentic behavior: you can get it only to the extent that it’s not apparent – to yourself or others – that you’re actively seeking it. And although esteem seeking involves empathy – it assumes taking the point of view of others in order to determine the most estimable move – it’s not an “empathetic” motivation in the laudatory sense intended by Shirky. But, of course, this doesn’t mean that we don’t genuinely like helping and hanging out with others. It just means we have both sorts of motivations.

Shirky clearly recognizes this fact since he qualifies the whole thing with "mainly." Most likely, he just wants to make the point that we often act socially for the non-optimizing, genuinely pro-social reasons we say we act. Our actions are generally genuine and not cynical. But this is the tricky part: I don’t think that recognizing the importance of esteem to most contributors automatically commits us to cynicism. Furthermore I don't think that the distinction between Shirky's "good" motivations and my market-like esteem considerations is all that clear and easy to maintain in the first place. Esteem, like self-interest generally, is what Philip Pettit and Geoffrey Brennan call a standby or virtual cause of behavior. It’s not what’s directly sought from your actions, but if esteem wasn’t provided, you’d be less likely to behave that way. It’s a bias that steers us rather than an explicit principle that guides us. Esteem – the positive evaluations of others by the norm-based standards of whatever reference group you’re using – is the emotionally powerful implicit incentive within social groups that maintains conformity while allowing constant competitive evolution. Seeking it isn’t necessarily cynical, rather it's inextricably woven into group-focused behavior.

Why on earth are we so afraid of “rational motivations” that we have to banish them almost completely from talk of group action online? Beats me. Anyway, as someone who has to design interaction spaces online I think it’s dogmatic, maybe even superstitions, to think that esteem motivations are somehow less real or powerful because “inauthentic” and self-serving. After all, in public goods experiments, we are shown to be conditionally cooperative, meaning that we cooperate with a self-serving bias. If norms of cooperation or reciprocation aren’t sufficiently salient or aren’t otherwise maintained, we tend to stop playing nice and settle for getting all we can. The desire for esteem and status can actually get people to observe and stabilize cooperative norms for purely self-centered reasons; they’re self-serving incentives for pro-social behavior . We should design accordingly.

In the next couple of posts I’ll look more closely at esteem seeking, Shirky’s book and the popular bias against instrumental motivations online. I’ll use the example of the development of the Linux operating system to illustrate the distinction between two different versions of social capital as well as two different takes on the free rider problem. Of course, both of them will utilize the idea of esteem along with Bourdieu’s idea of the “economy of symbolic goods.”

The Miscellany, Nominalism and The Essence of the Web

[NOTE: This version originally appeared on Armchair Media's blog. The more verbose version that was here has been removed... it was a drag.]

Given the tagged, user generated nature of the web today, is Information Architecture a dead practice that just won’t lay down? Are rigid ontologies a crime against the intrinsic nature of content on the web? Do outdated, hierarchical ways of ordering content on the web commit us to stifling and misleadingly authoritative structures that curtail innovation and invention?

David Weinberger seems to think so. He doesn’t like hierarchies, taxonomies or narrow instrumental classifications. His latest book, Everything is Miscellaneous, is devoted to drawing out just how inadequate these structures are when applied to the distributed, messy heap of content on the web. This isn’t a particularly new observation. Clay Shirky has been speaking to this point for years now. The basic idea is that the classificatory structures that we use to deal with the very real constraints of the physical world lend an artificial “essentialist” necessity to our task-based classificatory practices online. Ordering and making sense of the welter of stuff that populates our closets and sciences is necessary given the limitations of the physical world. That doesn’t mean they’re necessarily “true” in some big, extra-systemic sense, however. The need for strict, pre-determined structure is mitigated online because computers are really good at creating ad hoc order out of an undifferentiated mess. Online, not everything needs one and only one place. Acting and designing as if it did at best limits the democratic/utopianist promise of the web and at worst imposes or perpetuates illegitimate power structures. My interest is in what this does to the practice of web design.

First of all, I agree with most of what Weinberger and Shirky say about the changed face of order on the web. The majority of content falls into a miscellany. It’s just a mess of digital artifacts awaiting order. Anyone can throw stuff out there and it doesn’t really matter where it resides. If it has metadata on it or we can read its content, we can find it again and probably even put it to some use for which it was never intended. It's the potential for order that’s important. Designers have been working out the implications of these ideas for years now. Apparently, Weinberger’s book is intended for the decision makers near the top that may not have worked out the implications of ideas like tagging.

A key target of Weinberger and Shirky’s ire are ontologies or data structures intended to explicate the concepts in some domain of knowledge. Ontologies, in the information sciences sense, are the cornerstone of the Semantic Web. Shirky uses the term more broadly, thinking of it in philosophical terms as the sorts of things countenanced by some system, the sorts of things that some domain recognizes as constituents. The claim is that ontologies lead to a species of essentialism, or the world view that everything has some set of properties that uniquely identifies it in all possible situations. Both Shirky and Weinberger spend a lot of their time pointing out the fact that most ontologies are arbitrary and conventional, but that they can give the impression of necessity or self-evidence. For them, different ontologies are just competing webs of more or less useful concepts. In holding this view we can refer to them as nominalists.

My problem with most influential nominalists on this and other points is that, if not read or followed carefully, they can give the impression that there’s no place for local, designed order online at all. In other words, sometimes their fervent tone gives the impression that there’s absolutely no room or reason for islands of structure built from the welter of free form content. In their desire to rout “ontologizing” hierarchies simply on principle, they obscure the fact that a task-based local structure doesn’t automatically engender a totalizing, absolutism. The local structures on most sites are about sense-making and communication, not world-making and dictation. For instance, Flickr, Weinberger’s favorite example isn’t really the free-wheeling heap of free-range content he casts it as. Content enters Flickr neatly, if minimally, categorized (“category” isn’t coextensive with “hierarchy”) by user, camera type, etc. One could almost say that the user provides a loose ontology for Flickr. The user, a sort of default set, is the center of gravity that holds Flickr together; it’s the initial structuring principle that gives the content its potential for further order and defines possible transformations. It’s a wonderfully loose binding, but without this initial act of minimal categorization, the potential for further arbitrary re-ordering is lost. Though Weinberger and Shirky clearly know this, they should probably state it more explicitly as their management level audience may not be in the trenches enough to cut through the polemic and hyperbole.

There’s no such thing as order ex nihilo. Computers are really good at aggregating if they’ve access to some sort of potential ordering mechanism (tags, official metadata, etc.). If it’s text, this could be pure content. If not, we need to attach something, thus Flickr’s initial, user determined set. If we’ve no handle by which to grab the content, it might as well not be there (particularly with images and video). This is not to say that there’s no emergent order, which is a separate issue entirely.

As we’ve been stating for years, Information Architecture in the old fashioned tree-structure sense does seem pretty irrelevant. Definitely so for IA in the grand, Peter Morville sense, in which all sites are trees, everything has one and only one spot and there’s very little cross-linking of paths. Still any structure that gives sense a la Flickr’s implicit categorization is a form of architecture. It’s an ordering principle that somehow sensibly aggregates content on a local scale. So we’ve no longer Information Architecture in which all structures are made from custom built materials. Rather it’s more of an information shanty town in which personal structures are built from the miscellaneous heap of common materials. But the important point is that it’s still architecture, and still reproduces common elements like doors, windows, etc (to stretch the metaphor a little thin). We need pools of order with understandable principles of manipulation that briefly and locally coordinate elements from the miscellany. This point is often obscured in Weinberger’s book and we, as designers, will have to pay the price once it starts to circulate within marketing departments.

And though Weinberger (at least) seems to frown upon instrumental concerns on the web, we tend to have to design sites that people use to do things. At an abstract level, the nature of the miscellaneous mess of content means that it becomes more useful the more content there is and the more it’s tagged. For example, the more people upload and interact with content on Flickr, the better your chance of finding photos tagged “fruitcake” that are actually pictures of fruitcakes. Tagging after all is often more about the tagger than the tagged. Once enough people are doing it, however, the tags start to become useful content locators; at high volumes, idiosyncrasies and bad tags tend to filter out. Unfortunately, this suggests that loose structures, based entirely on tags tend to have an instrumental usefulness that varies with content volume and interaction. The moral: if you’re working on a project with
a smallish expected volume that needs to be useful out of the gate, you may still need to impose a strict categorization scheme in order to meet you goal. This, to Weinberger, is a sin, or at least a backwards looking crime against the essence of the web. At least that’s the impression one gets reading the book. (Shirky takes a more nuanced, “domain of discourse” based approached)

On the ground, designers realize that these quicksilver, local categorizations are the fundamental means by which we define our sites and some of our only means of communication online. They’re a part of the language of the web through which we communicate our clients’ messages. Without these structures, there would be no sites per se, just a grey fog of rootless content awaiting individual requests for order. This can’t be what Weinberger has in mind. Yes, Google is hugely popular. But it’s also a high-level general ordering mechanism and a liminal space intended to get people through it, not to it. The success of Google at what it does does not mean that we should all follow that example. Unless all we want to build from here on out are search engines.

So, we all agree that, in general, top down hierarchies are less and less relevant to a distributed, open access dumping ground like the web. And, of course, nobody really thinks that there’s only one relevant ontology. Ontologies are domain specific and the attributes assumed within them are never intended to be intrinsic to the content. Still, the need for order comes from two directions: the client and the user. Sites are doors into the mass of content, zones of order that communicate in part through the principles they impose on the miscellany. Users don’t yet want to get down to the level of the miscellany. Google, is the closest we like to get: a presentation of an ostensibly ordered set bound together by some minimal user-defined “intension.” The lower level domain-specific sites we generally concern ourselves with usually require a tighter sense of order than something high-level like Google. In general, as domain specificity increases so too the appropriate ordering principles (conventional content breaks, vocabulary, etc.). Users want a certain decrease in uncertainty as they become more specific in their searching behavior, but I agree that they never want its elimination. This is what the new ordering principles are all about. Allowing local order without stripping away the global properties of the miscellany.
