Name another profession where predicting the future is accepted as part of normal job performance. Stock brokers, fund managers, politicians and fortune tellers all fail. One thing I think that we overlook is the benefit that can be derived by using unknown information. The areas that are unknown while not quantifiable can fall into an area that defined by the known. The use of the K-Wave provides a frame work to measure the range of the known and unknown.
Events feed each other.
This allows us to rule out events that are not likely at certain point along the wave. For example, high interest rates and high oil prices are unlikely during this phase of the wave. Knowing this we can ignore some of the events that produced high interest rates and oil prices in the 1970's. This classifying of information along the lines of the long wave while not necessarily predicting the future allows one to pick which investment trends to follow. I am not sure anyone can do better than this.
