Obviously some people lie more often than others. What’s surprising is new research showing that the spread of lying propensity through the population is uneven. There is a large majority of “everyday liars”, and a small minority of “prolific liars”.

A few years ago Kim Serota and his colleagues put a figure on this. They surveyed a thousand US citizens and found that five per cent of the sample were responsible for 50 per cent of all lies told. Now Serota’s group have analysed data from nearly 3000 people in the UK and they’ve found the same pattern – the existence in the population of a minority of extremely prolific liars.

This new online survey is based on data collected as part of a public engagement project by the Science Museum in London in the Spring of 2010. Participants (51 per cent were female; average age 44.5) reported how often they told little white lies and how often they told big lies, as well as sharing their attitudes to, and experiences of lying.

The spread of answers was clearly skewed. Serota’s statistical analysis showed that 9.7 per cent of the UK sample were prolific liars. They averaged 6.32 little white lies per day and 2.86 big lies per day, compared with an average of 1.16 daily white lies and 0.15 daily big lies (about one per week) by the majority group of everyday liars.
