[单项选择] Communications technologies are far from equal when it comes to conveying the truth. The first study to compare honesty across a range of communications media has found that emails are automatically recorded — and can come back to haunt (困扰) you — appears to be the key to the finding.
Jeff Hancock of Cornell University in Ithaca. New York, asked 30 students to keep a communications diary for a week. In it they noted the number of conversations or email exchanges they had lasting more than 10 minutes, and confessed to how many lies they told. Hancock then worked out the number of lies per conversation for each medium. He found that lies made up 14 per cent of emails, 21 per cent of instant messages, 27 per cent of face-to-face interactions and an astonishing 37 per cent of phone calls.
His results, to be presented at the conference on human-computer interaction in Vienna, Austria, in April, have surprised psychologists. Some expected entailers to be the biggest liars, reasoni
A. people are less likely to lie in instant messages
B. people are unlikely to lie in face-to-face interactions
C. people are most likely to lie in email communication
D. people are twice as likely to lie in phone conversations

Communication technologies are far from equal when it comes to conveying the truth. The first study to compare honesty across a range of communications media has found that people are twice as likely to tell lies in phone conversations as they are in E-mails. The fact that E-mails are automatically recorded--and can come back to haunt(困扰) you--appears to be the key to the finding.
