·         Man et al conducted a study on police officers ability to detect suspects lies, aiming to see whether they'd be able to do so or not during interviews.



·         Previous research has shown that accuracy rates are very low, and that there is a 'truth bias', whereby ordinary people are more likely to guess that someone is being truthful than lying if they are unsure.



·         99 ordinary police officers from kent in the UK. 24 females, 75 males, average time in the service 11 years.



·         Field experiment.

·         Participants approached, asked if they'd take part in a study about police officers ability to detect deception - told their participation was anonymous.
