Write up

1.  Suppose, hypothetically, that you built a lie detector for  (a) email, (b) Skype.  Let's say your phone vibrated whenever a lie was detected.  Discuss the sender and receiver costs of this signal in each of these scenarios.  For each scenario, describe the costs when the systems incorrectly suggest a lie and when they "miss" a lie.

2.  As an alternative to the system described above, instead of explicitly alerting the user that a "lie" occured, how might you design an interface to encourage "authenticity" in interaction.  Make sketches with descriptions for email and Skype for a specific scenario.  Describe your design choices.  Would this improve the quality of conversation in romantic, businness, courtroom, classroom settings?  Compare and contrast to no change in the interface.

3.  Deception is encouraged in some online communities (ex. online poker).  In other communities, deception can result in higher sender and receiver costs (ex.  health forums, wikipedia, etc.).  Choose two online communities - one where the cost of lying to the receiver is high and one where it is low.  Discuss what, if any punishment policies or norms have evolved in these communities.
