The reach of global communication is expanding through the growing availability of smartphones. Smartphones are particularly popular for texting and voice/video calls, and their affordability means that more and more people around the world can now communicate with each other. Yet with the spread of global communication also comes increased exposure to deceptive communication. Can people in one culture accurately detect deception across cultures? And does the communication media they use play a role in their detection accuracy? We attempt to answer these two research questions in a study of Australian and US judges who were asked to detect deception in Australians and Americans, across four different media: full audiovisual, video only, audio only, and text. We found that both Australians and Americans could accurately detect deception at about the same rate across both cultures, and they were better at detection when exposed to full audiovisual stimuli compared to text.
