Studying Psychology is often like the ole nursery rhyme Humpty Dumpty
Humpty Dumpty sat on a wall
Humpty Dumpty had a great fall
It's easy to push Humpty Dumpty off the wall and break him into pieces, or in Psychology, variables and constructs. We break behavior, personality, thoughts and emotion into teeny little parts and look at them as individual components that make up a human being.
But when we try to put Humpty Dumpty back together again, he's just never the same egg.
All the king's horses and all the king's men
couldn't put Humpty together again.
