Encrypted N.I.
Encryption in natural intelligence is when the human mind layers, like a map overlay in Google GPS maps: satellite, terrain, street view, etc. but using symbology.
You are the only one with the codex who can interpret the information your own brain Encoded, like using phonetic memory tools for studying for a test, or memorizing.
This phenomenon, this unique human experience, individualized per person is a translation of your own personal language.
Natural Intelligence includes Encryption. We by nature are all cryptologists.
