- [Voiceover] So how do we go about trying to explain
the behavior of other people around us?
Well, we do it in a few different ways.
One of the things that we do is try and break down
our understanding and explanations of their behavior
into factors about them and factors
related to their environment and surroundings.
And there's two terms for each one of these
that I want you to know.
So, if it's about them, I want you to know internal.
Another word for that would be dispositional.
And also external, and another word for that
would be situational.
And what we're really talking about here
is a theory called Attribution Theory.
And this is how we find explanations
for the behaviors of others.
And I want you to actually pay attention to this blue line
that I've drawn in the middle.
Because in reality, the behavior of other people
is on a spectrum.
There may very well be a combination of
internal and external factors.
So what bits of information can we use to determine
whether we think someone's behavior is attributed
to internal or dispositional causes, or it's
related more to external factors and their situation?
And one of the theories we can use is
the covariation model.
So, let us take our forever flaky friend,
and let us look at a calendar.
What we're trying to do with our friend is
we're trying to go and watch a movie.
And what we find is our friend forever cancels on us.
We can't ever get them to go to the movie.
"I have to wash my laundry.
"I have to dry my hair.
"I have to fix my car."
And over the course of a month, we notice that
they have consistently displayed
the same behavior over time.
And when there's a high level of this consistent
behavior over time, we are more likely to think
that this is related to our friend being
a forever flaky friend.
It's more likely related to them as a person,
as opposed to the world working against them
to stop them coming and watching this movie with us.
So, when consistency is high,
we're more likely to attribute it
towards, the behavior, towards internal factors.
Now, let us consider another one of our friends.
So, Jim...
Is one our most relaxed, friendly,
warm friends.
We really don't have a friend that's more relaxed
or more warm than Jim.
Now, one of the things we find is one day,
Jim goes to get pizza.
And what happens is Jim becomes furious.
Jim becomes absolutely furious.
They get his order wrong.
They drop the pizza on the floor.
He gets so mad.
It's really, really, really
out of character and distinctive.
And really, we're like, "Wow, this is such
"an unusual situation."
This is really out of character for Jim.
And in this case what we think is that this is
much more related to the situation
or the environment that we find ourselves in.
That this is much more related to the situation
of being in a pizza parlor.
We don't think that Jim is naturally this aggressive
and hostile person, but his behavior
we're going to attribute to this situational,
or these external factors.
And finally, in the covariation model,
we have a third factor.
Have you ever heard of the term group lateness?
You probably haven't, because I kind of
just made that term up.
But what that means is that if you arrive late to a meeting,
but you're with 20 other people, and they're all late,
there's a high degree of consensus.
And what that means is that a lot of people
are demonstrating the same behavior.
When a lot of people are demonstrating the same behavior,
we start to think, "You know what?
"If everybody's late, it's probably something to do
"with their environment, something probably to do
"with their situation.
"There's no parking, the weather was bad,
"the elevator got stuck."
And in that case, a high level of consensus
means that we're more likely to attribute the behavior
to a situational cause, as opposed to an internal factor.
So these are the three important cues
of Kelley's Covariation Model.
