You might text your friend a white lie to get out of going to dinner, exaggerate your height on a CV online to appear more attractive or invent an excuse for your boss over email to save face.
Social psychologists have long wondered where people tend to lie the most——that is, in person or through some other communication medium. A 2004 study was among the first to investigate the connection between deception rates and technology. Jeff Hancock’s team had 28 students report the number of social interactions they had through face-to- face communication, the phone, instant messaging and email over seven days. Students also reported the number of times they lied in each social interaction.
The results suggested people told the most lies or the phone and the fewest through email, which is broadly in line with a “feature-based model”. According to the model, specific aspects of a technology—whether people can communicate back and forth smoothly, whether the messages are fleeting and whether communicators are distant— predict where people tend to lie the most.
When Hancock conducted his study, few students had a Facebook account. The iPhone was in its early stage. What would his results look like nearly 20 years later?
In a new study，I recruited（招募）250 people and studied interactions from more forms of technology. The participants recorded their social interactions and number of interactions with a lie over seven days, across face-to-face communication, social media, the phone, texting, video chat and email. The results show people seem to lie according to the "feature-based model".
There are several possible explanations for these results. Phone and video chat, for example, might make deception less costly to a social relationship if caught. Deception rates might also differ across technology because people use some forms of technology for certain social relationships. For example， people might only email their colleagues （ 同事）, while video chat might be a better fit for more personal relationships.
People often believe just because we use technology to interact, honesty is harder to come by. Not only is this perception（看法）misguided, but it is also unsupported by enough evidence. The belief that lying is common in the digital age just doesn’t match the data.
