New UChicago-led research suggests that someone who speaks in a foreign language is probably more credible than the average native speaker.
Boaz Keysar, professor of psychology at the University of Chicago, and Yoella Bereby-Meyer, professor in psychology at Ben-Gurion University of the Negev in Israel, co-authored a recent paper in Topics in Cognitive Science that sheds new light on the role language plays in the natural impulse to lie.
In the research, native speakers of English, Spanish, Hebrew and Korean in four countries were invited to play a dice game in which they were paid according to the numbers they reported. Participants who used a foreign language were less likely to cheat than those using their native language, researchers found.
