The problem was insoluble, until we could shift our paradigm. Our paradigms may be true, or not. The change is not a result of disproving a paradigm, but a decision. As long as we function within a paradigm, we cannot test it. We will gather information that is consistent with the paradigm, and dismiss the remainder of our data as irrelevant.
Science makes major progress when the paradigms are changed.
In biology today we are in the transitional stages of changing paradigms. During such a time, clear communication is difficult because terminology, models, accepted concepts are developed within a paradigm that is being changed, and we often are unconsciously jumping from one paradigm to another, and back again. We are very much in this situation in genetics today, and it is for this reason that we spend so much effort learning to recognize when we are in one paradigm and when we are moving into another. Otherwise, we will overlook vital information, get frustrated and confused, and become progressively more paralyzed in understanding success, and recognizing misdirections and false claims made under an inappropriate paradigm.
