It turns out that Collodi wasn’t far off reality. Most
people offer obvious telltale signs when they’re lying. Not a
growing nose, but close enough.
In a study of the components of lying,^2 Harvard
Business School professor Deepak Malhotra and his
coauthors found that, on average, liars use more words than
truth tellers and use far more third-person pronouns. They
start talking about him, her, it, one, they, and their rather

and the lie.
And they discovered that liars tend to speak in more
complex sentences in an attempt to win over their suspicious
counterparts. It’s what W. C. Fields meant when he talked
about baffling someone with bullshit. The researchers
dubbed this the Pinocchio Effect because, just like
Pinocchio’s nose, the number of words grew along with the
lie. People who are lying are, understandably, more worried
about being believed, so they work harder—too hard, as it
were—at being believable.
PAY ATTENTION TO THEIR USAGE OF PRONOUNS
The use of pronouns by a counterpart can also help give

implementation chains on the other side of the table. The
more in love they are with “I,” “me,” and “my” the less
important they are.
Conversely, the harder it is to get a first person pronoun
