Alf Boxall – did he blink?
Liars blink in different ways during and after a falsehood, researchers claim.
They blink less than normal during the lie, and then have a flurry up to eight times faster than usual afterwards.
‘It is striking what different patterns in eye blinks emerged for liars and truth tellers,’ said Dr Sharon Leal, co-author of the study at Portsmouth University.
‘Such striking differences in behaviour between liars and truth tellers are rarely seen in deception research.’
The psychologists say that the discovery, reported in the Journal of Non-verbal Behaviour, means that blink rates could be used by professionals to catch liars.

Liars tend to blink more because lying is stressful. Under stress, eye blink rate increases (Mann, 2013). People tend to blink more rapidly when they become nervous or when they hear or see something unpleasant (Navarro & Schafer, 2001). Ralph Waldo Emerson once said, “The eyes of men converse as much as their tongues” (Nelson, A., 2010).

Alf Boxall shows great mastery in this interview in that he only had to lie once, according to Dobson and Schafer, at every other instance he turned his answer into a truthful narrative.
