The paper "Deception and Design: The Impact of Communication Technology on Lying Behavior"describes an investigation into whether lying is less common in face-to-face communication than in other forms of communication such as phone conversations ore-mail.Participants in this study were30 studentsin anupper-divisioncommunications course at Cornell University who received course credit for participation. Participants were asked to record all of their social interactions for a week, making note of any lies told.

Based on data from these records, the authors of the paper concluded that students lie more often in phone conversations than inface-to-faceconversations and more often inface-to-faceconversations than ine-mail.

Discuss the limitations of this study, commenting on the way the sample was selected and potential sources of bias. (Select all that apply.)

A. Participants were asked to record all of their social interactions for a week, instead of a month.

B. Students may not have admitted all the lies they told, which would distort the results of the study.

C. Students knew that they were surveying themselves as to the truthfulness of their interactions, which could have changed student's behavior and distorted the results of the study.

D. The study only asked 30 students, instead of the whole class.

E. Since the students were all from an upper-division communications course at Cornell, it is not reasonable to consider these students to be representative of all students.
