Researchers decode 1950 cipher left as a posthumous test for life after death

GoKawiil Brief

A cipher created around 1950 by a researcher, built on a method devised by psychologist Robert Thouless, has reportedly been solved. Thouless had outlined the technique in a 1948 paper titled 'A Test of Survival,' which used an unbreakable-without-key cipher system, demonstrated with the phrase 'THERE IS NO DEATH' encrypted using Hamlet's 'To be or not to be' speech as the key.

Why It Matters

GoKawiil's interpretation of the reporting above, not reported fact.

The original experiment was designed so that only a medium who could contact the deceased creator would supposedly be able to reveal the secret key, making it a test of survival after death. Solving the cipher through conventional cryptographic means, rather than paranormal contact, suggests the test's core premise—unbreakable without the key—may not have held up against modern decryption techniques.
