If you understand the laws of gravity, you know that if you hold an object in the air and let go of it, it will drop to the ground. That is a law that always works. In the same way, behavior is a science, and it always functions in a specific way. Most people don’t know that, and that’s why we have pets that misbehave, it’s why there are problems in the workplace, it’s why there’s divorce.
Whenever you see a dog doing a cute behavior, people say, “He’s so smart!” Well, he might be, but that’s not what makes an animal trainable. Training happens because of good use of operant conditioning. I can train an earthworm to do behaviors as quickly and easily as I can a Harvard graduate, though I’ll run out of things I can train an earthworm to do pretty quickly.
