But to argue that privacy has no direct effect at all? I take issue with the fact that they draw this conclusion based on a very short list of studies, all of which are extremely limited in their scope and focus on very narrow dimensions of privacy. In particular, the work in behavioral economics frames privacy as a cost issue, and not all privacy issues are related to cost, either in time or actual money.

6. Computer-Mediated Communication
There are a few assumptions here that I don't entirely agree with. One, that we actively choose whether or not to enter into a relationship and who we enter into a relationship with based on whether we trust them or not. We are often in situations where relationships are thrust upon us, often based on role/job interdependence and a reliance on one and another to fulfill expectations.

Hardin takes a linear and predictive view that trust is built by iterated reciprocal exchanges, while last week's paper found that the naïve are more trusting. (The combination of "those who frequently engage in such activities also tend to have a greater sense of Internet discretion "

12. Using Games and Game Theory to Understand Trust-Building
What exactly is it that participants are exchanging in these games? Usually some sort of currency that can be redeemed for money at the end of the session, thereby establishing some risk.

13. Rules for the CMC trust game…
Two players
Each player gets 5 items from the experimenter on each round.
Players simultaneously decide whether to ‘entrust’ 0 to 5 of their items to the other player.
Players decide whether to return the items to the partner or not.
If player returns the items, the experimenter DOUBLES the amount returned to the partner (operationalizing benefit of fulfilled entrustment).
But, each player can just keep the entrusted items; then nothing is returned to the partner.

For Example…
Player A entrusts 1 X’s
Player A returns the 3 X; Player B gets 6X!
Player A
Player B
Player B returns the 1 X; Player A gets 2X!
At the end of the round, you keep whatever you did not entrust, plus whatever you earned or kept from your partner!!
Player B entrusts 3 X’s

Debriefing…
What were the risks?
What were the sources of uncertainty?
What are the opportunity cost(s) in this game?
Does the game play any differently when there are repeated interactions with the same partner, compared to when there are new, random partners?

I question how well these laboratory findings translate into actual interactions. We trust someone to do a particular thing. And in this case, the thing is a very specific, rather artificial social dilemma game, performed in a controlled setting. If the goal of this study was to gain insight into effective collaboration across long distances, how well does the social dilemma game model actual work?

However, the Bos et al. study may not be strong evidence for trust needing touch. First, the experimenters banned social conversation from the experiment. This immediately placed the “richer” media conditions at an advantage because visual and aural cues normally compensated for in CMC social communication could not be in this sterile environment. Second, and related, such games are artificial in the extreme and have little relationship to how people actually use media. Third, the time given to the experiment was not sufficient for the text-based condition to “catch up” with the media with faster communication exchange (Walther, 1992). Finally, the use of self-reports for trust is unreliable because people tend to rate richer media as higher in trust, despite evidence that communication is more effective without identity cues for experienced users (Tanis & Postmes, 2007).
