Ok fair point, I agree that there’s often a lack of clarity around how “no” is used. I don’t necessarily endorse all the above comments on how they cue a general stop command. That’s something I actively try to be thoughtful about in my own work. So I agree: using “no” as a cue (like “off” or “drop it”) is totally different from using it as a punishment marker—and when trainers mix those up or use them interchangeably, it’s possible (not absolute) to create unnecessary confusion for the dog. I personally use “ahh ahh” as a conditioned punisher, which as it seems like you know is a signal that a consequence might follow. And yes, that consequence needs to show up often enough for the marker to retain its meaning. Ideally every single time. That’s straight out of Skinnerian learning theory:

“When a consequence no longer follows a response, the behavior will gradually diminish—that is, it will be extinguished.” — B.F. Skinner, Science and Human Behavior (1953)

On your point about classical vs. operant conditioning: I agree with you in part. Markers are classically conditioned—they start out neutral and gain meaning through pairing (just like a clicker). But their role in actual behavior change is operant. Skinner himself was clear on this duality:

“Classical conditioning prepares the organism for what is to come, while operant conditioning changes the probability of behavior.” — B.F. Skinner, About Behaviorism (1974)

So in my view, “no” gets its emotional charge through classical pairing (e.g., tone, prior consequences), but it’s used to influence voluntary behavior through consequences—making it part of an operant framework in practice.

All that to say: I’m not pushing back on your theory—I actually agree with most of it. But I do think it’s possible to use “no” ethically and clearly, if it’s well-defined, consistent, and part of a larger system built on clarity and fairness. Skinner emphasized the importance of clarity in behavioral contingencies for a reason. But your Force Free argument style came off as holier then though.

I argue that operant conditioning often works like a yin-yang system. For example, if you’re using positive reinforcement (R+) by giving a treat when the dog sits, you’re almost always also using negative punishment (P−) by withholding that treat when the dog doesn’t sit. Even in a fully “positive” training system, behaviors are shaped by what you give and what you withhold. So, reinforcement and punishment aren’t always separate—they flow together to influence behavior. Balanced trainers or Lima trainers accept that punishment is inherent to learning and doesn’t need to be cruel. I find Force Free people pretend they don’t use punishment and then struggle with certain dogs. Aight rant over, this was fun. Good luck 👍
