Okay.
So once again I want to make the point that
there's not one non-verbal indication or not
one verbal indication of whether or not someone
is lying.
There's only non-verbals indications that
are correlated with lying.
So one of the things you're going to want
to do is I'm telling you all of these different
ways of determining whether or not someone's
lying with speech.
Just because somebody does it, it doesn't
mean that they're lying.
It can be a red flag.
So if you see a bunch of these behaviors you
can say to yourself, 'Mmm.
Is this an area where I might need to probe
a little bit deeper?'
Okay?
So in terms of speech, there's a correlation
between response time.
One of the most interesting things with speech
and lie detection is spontaneous correction.
So essentially liars are less likely to correct
themselves.
And the reason why is because they want their
presentation to be more believable so their
less likely to correct themselves.
Right?
So if you told a story that was truthful,
you don't mind going back and saying, 'You
know, that wasn't true.
We were there not there.'
But when you're lying what to you want to
do?
You just want it to be flawless.
So they're less likely to actually correct
themselves.
Liars tend to make more errors in general.
All right?
So they make more errors and they usually
don't correct them.
Liars also tend to pause more often or say
things like 'Mmm' or 'Umm'.
But that doesn't mean they're lying.
Some people just do that.
Some people when they talk they just kind
of talk like that.
So you have to be careful and you usually
want to see clusters of these kind of speech
patterns, like three or five.
Liars also tend to be just less fluent.
There's a lack of fluency in their delivery.
There tends to be a lot of breaks, a lot of
pauses.
It doesn't come off as believable.
And what's really interesting is if you see
somebody who's a really good communicator
and they never have problems, they talk well,
they don't mess up.
And then all of a sudden, during a certain
area, they tend to mess up, it tends to mean
something.
Right?
It could mean something.
