Do experiences of synchronicity between adoption-separated parents and children confirm a continuing bond or genetic affinity that transcends space and time? Carl Jung knew "synchronicity" to be a subjective experience with significant time and meaning for the participant, a clue to an underlying system of science and spirituality. Paul Kammerer used simple physical analogies for such coincidences and defined the "law of seriality" as a unifying principle at work in the universe, correlating by affinity. He believed this pull toward unity produces concurrent or serial events in space and time, bringing like and like together. After search and reunion, adoptees and birthparents begin to piece together the long years of separation and to seek their own explanations for uncanny coincidental behavior and meaningful information transfer that occurred when normal sensory contact was absent. This psychophilosophical exploration of the anecdotes of 70 reunited families will certainly stimulate subsequent investigation.
