What are some psychological experiments with interesting results?

White rats and black rats were raised separately without seeing each other.

When a black rat was placed in the white rat's cage, the other rats ostracized him.

When white rats and black rats are raised together and a new black rat is placed in a cage,

the white rats accept him.

So basically, rats are racist and less raised to accept differences. The self-fulfilling

prophecy studies are very important to social psychology and their findings have many real-world

applications. Basically, they brought together a group of kids and formed a class with a real

teacher. They gave the kids a test for overall academic skill at the start of the course,

but didn't really use the scores. Instead, they told the

teachers that a few students picked at random were very brilliant and scored very highly. They then

observed the class for a long period of time and noticed that the teachers gave the kids they

thought were brilliant much more attention. At the end of the study, the kids took the test again,

and they found that the kids who were randomly named brilliant at the start actually scored higher than the rest of the class.

The kids again, at the start, didn't score any different from the rest of the class, but through the self-fulfilling prophecy, they became the best in their class.

This obviously has tons of applications in the real world and especially education.

The Monster Experiment. Although it is horrible how they left the children with mental health issues at the end,

the experiment gave very good insight to how to parent a child.

In this experiment, they took groups of orphan children and separated them into three groups.

One was the control, the second were told they had a lisp and were doing bad,

and the third was told that their speech was perfect. As the experiment went on, group two began

developing lisps after being berated constantly. They became shy and reserved. They were scared to
