Facts have a shelf life. In time, many of today's assumptions will be proven false. Some people will hang on to these beliefs, unable to grasp the new truths.
Our understanding of the world grows by both adding and subtracting knowledge. As our understanding grows, so do the questions we must ask. The more we learn, the more we realize how little we know.
If every truth of today is tomorrow's laughable idea, how can we move forward?
If we can assume all truths will be proven (at least somewhat) false, and we don't yet know which false things will be proven true, should we consider all things false? Should we assume we know nothing?
And if so, how do we move forward?
I certainly don't have the answer, but I think I have a way forward. At least professionally.
As coaches, we need to teach based on what we believe to be true, but we must constantly update our version of reality to meet the frontier. We must be willing to go back on our beliefs from last decade, last year, last week, or yesterday. We must give our players the best we have now, but never be so sure in ourselves that we stop learning.
