Every human being does not only create many alternative time paths into the future, but it stores them: we have a Memory of the Future. Ingvar’s hypothesis says that this Memory of the Future serves to filter out any signal from the outside world that is not relevant to that individual’s future, i.e. to any of his stored alternative time paths. The corollary of this hypothesis is that any individual (or company for that matter) that has explored few futures, hears or sees very little. A company with only one Strategy (singular) or one Plan is virtually blind or deaf. Scenarios are the obvious way to improve this situation.
