I recently listened to an interview with Walter Isaacson Walter Isaacson discussing First-Principles Thinking amongst other very interesting concepts. It got me thinking about how we approach dog training and how often we accept a rule without questioning the reasoning behind it.
First-Principles Thinking means examining our assumptions, returning to the fundamentals, and building our approach from there.
Many years ago, I was taught, โYou never do blind crosses.โ More recently, I have heard, โYou should never use your outside arm unless itโs a threadle."
When I hear โnever,โ I want to understand WHY and I think we all need to question these absolutes. My question when I hear these absolutes is whether this is a principle of learning or a rule within a particular handling system?
A handling system can provide valuable consistency but we need to understand what a rule accomplishes, when it is useful, and whether it needs to apply in every situation.
The arm signals we use develop through the dogโs learning history and the context in which we use it. So rather than stopping at โYou canโt use that arm,โ we probably should ask:
โข What has the dog learned that signal means?
โข Can the dog distinguish it from other signals?
โข Are our timing, movement, and position providing clear information?
โข What do we observe when we use it?
โข If we use the outside arm for something other than a threadle, does the dog understand what it means, and does it provide clear information about where to go?
The same thinking applies when a dog struggles in training. Before deciding the dog needs more encouragement, more repetitions, or a different technique, we can examine what happens before the behavior, what the dog actually does, and what consequences follow we need to as the following questions:
1. Does the dog understand what I am teaching?
2. What have we reinforced or has the correct behavior been reinforced?
3. Are we making the task difficult?
4. Is the environment too overwhelming.
5. Could discomfort, fatigue, or worry be affecting participation?
The principles of behavior and learning give us a foundation for investigating these questions. We can make a thoughtful change, and observe the result. We can then make adjustments including when the results challenge our own beliefs.
For me, First-Principles Thinking means being willing to ask โWhat is the reason behind this rule, and does that reason apply to the dog and situation in front of me?โ
What training rule have YOU questioned and what did you learn?
