While I've used that conflict avoidance approach there are two sides of the issue you reference. On one side you have the people with the least experience and shortest perspective convinced that they know best while on the other hand are the people with the longest experience but most set in their ways are also convinced they're right.

In my experience both tend to be wrong more often than not. Neither wants to listen to the other for the reasons above and then fail to benefit from the others experience.
