Bicchieri, Cristina, and Lev-On, Azi. 2011. Studying the ethical implications of e-trust in the lab. Ethics and Information Technology, 13(1), 5-15.
The paper presents results of recent laboratory experiments that study if and how computer-mediated communication affects cooperation and trust. It is argued that communication medium does not matter much for trust-building and maintenance, whereas relevant pre-play communication and group size can have a major influence. The implications of the findings for the design of sites that depend on trusting communities are discussed.
