Afterlife Codes Project: “The history and scientific foundation of the Susy Smith Project is described in Schwartz and Russek (1997c).

Briefly, one way to test the SOC hypothesis is to determine whether a key phrase known only to a person in

life (termed the sender) can be communicated after the sender has died (Berger, 1984). To ensure that the

key phrase is not inadvertently communicted by someone (such as a research assistant) who is living after the

sender dies, the key phrase is encoded by various coding systems and the correct key phrase is required to

decode the encoded information.”
