We had chicken last night and I think it was bad. Woke up at three this morning and felt awful. Was sick for four hours. Saw the doctor but he wasn’t any help. Am exhausted.

The new software is being developed by a team led by Jeff Hancock. “We asked people to come into the labs and write lies, and we had other people come in and write the truth,” says Hancock. “Using this method, we’ve built up a database of tens of thousands of emails.” The scientists have analysed the data and identified a number of simple tests to predict whether or not a person is lying. One of the most important tests is the length of a message. Lying emails have, on average, 28% more words than truthful messages. Another sign is the overuse of sense words, such as ‘see’, ‘feel’ and ‘touch’. “When you’re lying, you want the other person to believe you, so you give more details,” says Hancock. Liars also tend to use pronouns like ‘we’ and ‘they’ rather than ‘I’ as a way of distancing themselves from a lie because they feel guilty. “People often use negative emotional words too, because they feel uncomfortable when they’re lying,” says Hancock. “So they’ll use terms like ‘sad’, ‘angry’, ‘unhappy’ and ‘stressed’.” Previous research has shown that up to one third of communications at work involve lying of some sort. The most common workplace lie is pretending to be sick to avoid going to work. But Peter Collett, a psychologist who has written a book on lying, is sceptical about Hancock’s work. “You can see if somebody is lying by looking at their body language, how fast they talk, and how they speak,” he says. “How can a computer program see all this? They’ve clearly done a lot of research, but with emails all you have is words.” 102 Language skills Extras Explore 8 Fiction and reality Nur zu Prüfzwecken – Eigentum des Verlags öbv
