Imagine for a moment that you have an area of expertise. You might have some pride about the amount of information you know.
You spent countless hours studying something from multiple angles. You have spent time practicing that. You read on the outside about it. You have personal as well as professional experience with it.
You can still be wrong within your expertise.
It can happen, right? You could be irrational or not logical or have a blind spot. Chances are good that your area of expertise is an area wherein you are often right.
Now imagine someone else, having seen your expertise and having a different, no less important expertise.
Imagine that someone else coming in and saying they know more about it, and that you have to follow their way of doing it instead of yours, the expert. That usually warrants a conversation and negotiation.
Imagine how that lands. “I know more about your area of expertise than you do,” is one possible way it lands.
For me, when I observe that in my office, it looks like a power play, an inability to accept the influence of the first person.
There are a few things that will need healing before proceeding when I see that.
What conversation might you need to have if that happened in your relationship?
