The Importance of Negative Reenforcement

The training process is that by definition, you have to apply a contingent aversive before you can make it work. If you're trying to use negative reinforcement to train a dog to sit, are you going to pull up on the leash or push the button on the e-collar? It's differential punishment of other. And some people, well, DPO doesn't appear in the literature. Yes, it does. You can find it, but it's not out there because people don't talk about it much. Why? Because it's a taboo subject. But the reality is if you've never even heard anyone say DPO, obviously everyone's familiar with DRO and DRI.
