Personality survives physical death and can be proven through experiments.

Corresponding to supplementary question 2: a double-blind automated telephone experiment can be conducted at two independent centers, with approximately 100 participants and a total of 20,000 forced-choice trials over 18-24 months. Independent custodians prepare approximately 100 verifiable multiple-choice questions (four options) from deceased persons that are not publicly available; the system uses random number generators to balance option positions, participants submit keypad answers via telephone, and experimenters in contact with participants do not know the answers. Pre-register fixed trial counts, primary endpoint of 25% chance level, participant- and deceased-clustered models, missing data and repetition handling, include fictitious identities and no-participant controls, and audit code, access logs, and information leakage. If additionally testing whether random number generator output is influenced by intention, this must be an independent experiment with independent hypotheses and cannot be mixed with question-answer hits. A stronger identity test could recruit living voluntary participants to seal high-entropy secrets and verify after natural death, estimated to require 3-5 years or longer.

Accuracy of Deceased-Person Information Retrieval in a Double-Blind Automated Forced-Choice Task

If other information sources can be excluded and continued activity of the same personality is confirmed, this would revise the hypothesis that personality and autobiographical memory cannot persist after irreversible termination of the brain functions supporting them.

"Can be proven through experiments" provides a testable commitment, but does not specify the communication channel, success criteria, or effect size lower bound; thus it is not more specific than existing survival hypotheses.

"Contested" indicates that relevant evidence and interpretations are disputed, and does not imply that post-mortem survival has been proven; even if hits are significant, one must distinguish leakage, scoring bias, anomalous information acquisition, and personality identity continuity; and this search did not find a fully validated experiment identical to the automated telephone protocol described.
