Radix Intelligence (RI) is the primal energy underpinning mind activity in its entirety. It is an elemental psychological quality based on the conception that the universe is made out of ideas, rather than atoms. The major area of application of Radix Intelligence is in behavioral prediction and the implicit assessment of so-called "dark traits".
