when trying to explain and predict actual player behaviour one may have to examine the personal motivations of players for doing what they do. A somewhat simplistic way of understanding the scope of (analytical) game theory as regards computer games would be to say that it applies to the extent that players try to achieve the goals presented by the game. It is crucial to remain aware that the "rationalism" implied in the approach is at best a useful approximation and that the accompanying assumptions about player behaviour are non-trivial.

JoSS: Journal of Social Structure

Visualizing the Signatures of Social Roles in Online Discussion Groups

www.cmu.edu/...Welser - Preview

cmc social-roles

The central premise of this paper is that we should be able to recognize the roles that people play by measuring behavioral and structural “signatures” of their participation.
he answer person is a well recognized social role in online discussion spaces (Golder 2003; Viegas and Smith 2004; Turner, Fisher, Smith, and Welser 2005). Substantively, they are important because answer people collectively donate vast amounts of valuable advice to those who ask questions, resulting in the creation of valuable online resources.

- We identify a structural signature for answer people with three features based on the local network attributes and the types of threads to which answer people tend to contribute. First, answer people tend to be disproportionately connected to alters with low degree. That is, they reply to relative isolates, authors who themselves answer few, if any, others. Second, their local (degree one) networks tend to have small proportions of three-cycles (i.e. their neighbors are not neighbors of each other) and they seldom send multiple messages to the same recipient (few intense ties). Finally, answer people tend to reply to discussion threads initiated by others and typically only contribute one or two messages per thread.
- a major research challenge is to develop the ability to identify groups with good information and identify valuable contributors without inspecting every message in a collection.

20 more annotations...
- disappointment is the appropriate response
  when one merely relied on someone to do something, but did not
  trust him or her to do it. People who monitor and constrain other
  people's behavior and do not allow them to prove their own
  trustworthiness may rely on others, but they do not trust them. For,
  while their reliance could be disappointed, it could not be betrayed.
  Consider that one can rely on inanimate objects (such as alarm clocks),
  but when they break, one is not betrayed, although one may feel
  disappointed. Reliance without the possibility of betrayal is not
  trust. Thus, people who rely on one another in a way that makes
  betrayal impossible do not trust one another.
- Rarely, if ever, do we trust people
  completely (i.e. A simply trusts B). Instead, “trust is generally
  a three-part relation: A trusts B to do X”
- Some philosophers believe that trustworthiness can be
  “compelled by the force of norms” or, more generally, by
  the force of social constraints
- An alternative to the social contract view is a view according to
  which trustworthy people are motivated by their own interest to
  maintain the relationship they have with the truster, which in turn
  encourages them to encapsulate the interests of that person in their
  own interests
- In the end, like the social contract view, the
  encapsulated interests view may describe reliability, but not
  trustworthiness.
- Risk-assessment theories in general are popular among
  rational decision theorists and social contract theorists, who presume
  that people are naturally self-interested.
- these accounts, unlike the goodwill account,
  fail to demand that the trustworthy person care about the
  truster, or care about what he or she cares about. Such caring appears,
  as we have seen, to be central to a complete account of
  trustworthiness.
- The particular reason why care is central is that it allows us to
  distinguish between trust and mere reliance. I have said the two
  differ, putatively, because only the former can be betrayed. But
  why is that true? Why can trust be betrayed, but not mere
  reliance? The answer Baier gives is that betrayal is the appropriate
  response to someone on whom one relied to act out of goodwill, as
  opposed to ill will, selfishness, or habit bred out of indifference
- It is not
  necessary, some say, because we can trust other people without
  presuming that they have goodwill.
- Although problematic, risk-assessment views do have their
  merits. For example, they seem to make better sense of trusting that
  strangers will be morally decent toward us, which surely can occur
  without assuming that strangers have goodwill toward us.
- Thus, optimism about goodwill is insufficient and,
  according to Karen Jones, needs to be coupled with the expectation that
  the trustee is “favorably moved by the thought that [you are]
  counting on her” (1996, 9).
- First, it appears that trust and rational reflection (e.g. on
  whether one should be trusting) are in tension with one another. Since
  trust inherently involves risk, any attempt to eliminate the risk
  through rational reflection could eliminate the trust at the same time.
- For example, it
  suggests that rational trust will always be partial rather than
  complete, because the rational truster is open to evidence that
  contradicts his or her trust on this theory, while someone who trusts
  completely in someone else lacks such openness.
- While, paradigmatically, trust is a relation that holds between two
  individuals, forces larger than those individuals inevitably shape
  their trust in one another.
- Trust enhances
  cooperation; because it removes the incentive to check up on other
  people, it makes cooperation with trust less complicated than
  cooperation without it
- The basic argument for the need to
  trust what others say is that no one person has the time, intellect,
  and experience necessary to learn, independently, facts about the world
  that many of us do know.
- Trudy Govier (1993) and Carolyn McLeod (2002) both
  assert that to be motivated to choose and act in accordance with our
  own values—that is, to choose and act autonomously—we need
  to trust ourselves to do so.
- While
  destroying trust is usually quick and almost always dirty, creating
  trust is often a slow and painful process
- That many people feel compelled to say, “I wish I could trust
  you,” suggests that Baier's view is correct: wishing or
  wanting is not enough. But Richard Holton interprets her view
  differently. According to him, Baier's point is that we can never
  decide to trust, not that we can never decide to trust for motivational
  purposes (1994).
- Holton gives the nice
  example of trusting a friend to be sincere without believing that the
  friend will be sincere

I would argue that PageRank does in fact rely very explicitly on a model which combines several layers of justification.
too many people think that mathematical methods for knowledge discovery (datamining that is) are neutral and objective tools that will find what’s really there and show the world as it is without the stain of human intentionality; these algorithms are therefore not seen as objects of political inquiry. In this view statistics is all about counting facts and only higher layers of abstraction (models, theories,…) can have a political dimension. But it matters what we count and how we count.

And Google clearly has. It doesn't need to develop a theory as to why a given pattern of links can serve as an indication of valuable information; all it needs to know is that an algorithm that recognizes specific link patterns satisfies its users.
Correlations are a way of catching a scientist's attention, but the models and mechanisms that explain them are how we make the predictions that not only advance science, but generate practical applications.

This is a world where massive amounts of data and applied mathematics replace every other tool that might be brought to bear. Out with every theory of human behavior, from linguistics to sociology. Forget taxonomy, ontology, and psychology. Who knows why people do what they do? The point is they do it, and we can track and measure it with unprecedented fidelity. With enough data, the numbers speak for themselves.
Petabytes allow us to say: "Correlation is enough." We can stop looking for models. We can analyze the data without hypotheses about what it might show.

Identity and Deception in the Virtual Community

smg.media.mit.edu/...IdentityDeception.html - Preview

identity virtual-world community cmc

Signals that follow the handicap principle are called assessment signals. They are costly and the cost is directly related to the trait being advertised. Big horns on a stag are an assessment signal for strength, for the animal must be quite strong and healthy to support these massive growths. The horns are a signal: potential rivals or mates need not directly test the stag's strength; they can simply look at the size of the horns. The thick neck of a brawny bouncer in a bar sends a similar signal in the human world and few patrons demand a personal exhibition of strength. Assessment signals are reliable, since sending an assessment signal requires that the sender possess the relevant trait.

Signals that do not follow the handicap principle are called conventional signals. Here, the signal is correlated with a trait is by custom or convention: the sender need not possess the trait in order to make the signal. Wearing a T-shirt that says ``Gold's Gym Powerlifter'' or signing ``Mr. Deadlift'' in your letters to a weight-lifting newsgroup is a signal of strength, but not a reliable one. Anyone can wear the shirt or type the signature: no feats of strength are involved in the signal's production. Conventional signals are open to deception. If being thought of as strong is highly desirable, it seems reasonable that many people, weak or strong, would choose to wear ``Powerlifter'' T-shirts. Yet, if T-shirt wearing by the weak becomes prevalent, the signal loses its meaning as an indicator of strength. Conventional signals can thus be unstable: due to excessive deception, a once meaningful signal can become noise.
