Here’s the abstract of a Boston University study led by postdoctoral fellow Natalie Emmons and published in the January 16, 2014 online edition of Child Development:
By examining children’s ideas about “prelife,” the time before conception, researchers found results which suggest that our bias toward immortality is a part of human intuition that naturally emerges early in life. And the part of us that is eternal, we believe, is not our skills or ability to reason, but rather our hopes, desires and emotions.
