Question 4 researchers endeavoring to conduct an on-line study should consider that there are some potential risks of harm to subjects unique to internet-based research. one of these risks is: online studies do not require the documentation of informed consent. people assume pseudonymous on-line identities, such as an avatar in an mmorpg. individuals may post private identifiable information about themselves on-line without intending it to be public and available to researchers. recruiting, consenting and debriefing subjects takes place on-line, and may require little to no interaction with the subjects.
