Louisa Rhine

American parapsychologist and J.B. Rhine's wife and scientific collaborator — who complemented the experimental laboratory work by studying thousands of spontaneous psychic experiences reported by ordinary people, compiling the most extensive database of spontaneous psi cases.

Demonstrated that psychic phenomena are not laboratory artifacts but real-world experiences reported by ordinary people across cultures — her case collection methodology established that spontaneous psi follows patterns (precognitive dreams more common than waking ESP, crisis cases most common) that make theoretical sense.
