Every conclusion you come to has a story behind it.
The story of what led to the conclusion is important. What were the experiences, who was involved, how did you interpret are all threads within the story.
Remembering the threads that led to the conclusion, allows you to keep your conviction in the conclusion strong.
Remembering the threads that led to the conclusion, allows you to understand when those threads are no longer valid and lead to re-evaluating the conclusion.
A true scientific theory always has the possibility of being disproven. It is the same with conclusions you have made in life, you should always be willing to re-evaluate the conclusion.
