By way of illustration, if you beat a dog, you know where the dog won&rsquo;t be. It won&rsquo;t be where you gave it the beating, but you have no idea where the dog will be. That&rsquo;s a negative incentive. If on the other hand, you feed a dog, it&rsquo;s a positive incentive and you know where the dog will be.
