There are numerous examples among animals and even lower life forms, that learning a task helps other members of the same species start learning that task more quickly. In humans, test scores like IQ measurements, have improved steadily over time without a convincing explanation and is called the Flynn effect, after its discoverer. The term morphic resonance has been used to describe these phenomena, but that still seems quite a vague description. How does human learning of specific information help others in the future somehow know and retain those facts more readily?

The explanation here is very straightforward, although esoteric, so one must understand the metaphysics of consciousness to appreciate how this can be so. The idea of morphic resonance is an intuitive perception that there is something about like, seeking and finding like, with a kind of vibrational criterion that has been observed with physical analogs demonstrating a resonance of one vibration with another. This intriguing phenomena is apparent with things like ticking clocks with a pendulum coming into unison on their own, seemingly, as well as even biologic phenomena like female animals and even humans synchronizing their menstrual periods when living together, and thus more likely to influence one another more strongly than the population as a whole. So, to answer your question specifically, the nonlocal consciousness of individuals, through this resonance, is visiting the collective unconscious, which is a repository of thoughts of all humans. And this explains why a scientific innovation by one individual, after a long history of ignorance, may be rapidly followed by other scientists completely unaware of each other, and even scattered across the globe, coming up with the same idea. This is simply a system feature of creation, that there is not only a Unity of Souls but a Unity of Consciousness to help the Soul Family advance and benefit from individual and collective thought.
