Patti Wood, a body language expert and the author of “Snap: Making the Most of First Impressions, Body Language & Charisma,” said that blinking rates under ordinary circumstances can vary widely depending on the person, such that 40 blinks per minute might also be a typical rate. So the key is to analyze what someone’s baseline is in different contexts.
“As stress increases, blink rate goes up to 70 blinks per minute or higher,” Wood said. “So, for example, you look at what a person’s blink rate is in a courtroom setting: How are they blinking most of the time? What is their baseline in that situation? Then you look at how their baseline rate changes due to certain factors — for example, when they ask a question and they’re stating their response, or when someone on the stand is saying something about them.”
If you’re trying to assess how someone’s blinking rate can change during questioning, Wood recommended mixing in more difficult questions with easier, fact-based inquiries. You may even ask the same tough question multiple times to get a better comparison. If their blinking pattern changes, you might want to get to the bottom of what they’re truly thinking.
“For example, in a job interview situation, you would ask them what’s making them uncomfortable about answering the question,” Wood said. “You should come from a place of integrity and curiosity. The goal should be to create conne
ction, establish a relationship with people so they feel comfortable telling you the truth, rather than have to fear everyone is lying and expend the energy trying to catch them. Research shows that people who [think they] are in the presence of an honest person with integrity, they are more likely to feel comfortable telling the truth.”
And remember that a change in blink pattern doesn’t necessarily mean someone is lying, so give people grace.
“There are many reasons why someone could have rapid blinking,” Wood said. Despite those studies showing some link between blinking and dishonesty, that’s not the whole picture, especially in a courtroom setting. After all, a person’s excessive blinking may simply stem from the stress of taking the stand in front of so many people.
“Blink rate is linked to a change or sudden shift in emotion. Now we have to accept that for any person, going into court with cameras present, reporting on every word we say, would be stressful.”https://www.huffpost.com/entry/blinking-lying-gwyneth-paltrow_l_642330c6e4b04efaae793fe7?fbclid=IwAR3SzO5wyxtUaPyaqZuHkaKyGqWcsPsfaLJabAs67R2xryrkhpT24u2OJCo
