@lcamtuf honestly it reminds me of this study https://people.psych.ucsb.edu/gazzaniga/PDF/Language%20after%20section%20of%20the%20cerebral%20commissueres%20(1967).pdf

They seperate the sides of the brain and try to communicate with them individually.

> when an object was placed in the left hand (right hemisphere sensing it), the speaking left hemisphere fabricated a verbal explanation for why the patient was holding it

Later studies (60s so could be horseshit) worked with a theory of one side being more of an interpreter.

@lcamtuf personally I think humans have a critical vulnerability in the interaction of being handed a completely plausible thought. Whether encoded as speech/electrical signals/vision once we are holding it we will invent reasons why it is correct.
That or we are just lazy haven't decided
