A final experiment that I want to mention
to you is our Fairness Study.

Past simple

This became a very famous study
and there's now many more because,

after we did this about ten years ago, 
it became very well known.

And we did that originally
with Capuchin monkeys

and I'm going to show you
the first experiment that we did.

It has now been done with dogs, 
and with birds, and with chimpanzees.

But we started out with Capuchin monkeys.

So what we did is we put 
two Capuchin monkeys side by side.

We take them out of the group 
and put them in a test chamber.

There's a very simple task
that they need to do.

And if you give both of them
cucumber for the task,

they're perfectly willing 
to do this 25 times in a row.

So cucumber, even though it's really only water
in my opinion, is perfectly fine for them.

the food preferences of my 
Capuchin monkeys correspond...

..exactly with the prices in the supermarket.

If you give them grapes, 
as a far better food,

It was new monkeys 
who have never done the task,

thinking maybe they would have a stronger reaction

The one on the left 
is a monkey who gets cucumber.

The one on the right 
is the one who gets grapes.

..that the first piece of cucumber is perfectly fine.

Then she sees the other one getting 
grape and you will see what happens.

So she gives a rock to us. That's the task.

And we give her a piece
of cucumber and she eats it.

The other one needs to give a rock to us.

And she eats it--
the other one sees that.

So this is basically the Wall Street 
protest that you see here.
