[1][17] Tucker felt unfulfilled by his work in child psychiatry, but was open to the possibility that humans are more than their material bodies and wished to investigate the matter further.

[18] Though raised as a Southern Baptist, Tucker does not subscribe to any particular religion, and claims to be skeptical about reincarnation,[7] but sees it as providing the best explanation for phenomena associated with the strongest cases investigated to date.

[20] Tucker reports that in about 70% of the cases of children claiming to remember past lives, the deceased died from an unnatural cause, suggesting that traumatic death may be linked to the hypothesized survival of self.

He further indicates that the time between death and apparent rebirth is, on average, sixteen months, and that unusual birth-marks might match fatal wounds suffered by the deceased.

[15] The documentary also briefly covered another of Tucker's cases: that of Gus Taylor from the Midwest U.S., who claimed from around the age of a year and a half to be his own grandfather returned to the family.
