In long; because the demonstration itself puts you & all of your hard work at a shoes disadvantage .. now imagine everyone having excellent telepathy skill by default just like everyone can tie shoes (& some without even looking at, lol) .. would demonstrating precognition still interest anyone then, or would the interest cease altogether? .. I guess then everyone would be asking to demonstrate how to lie & still no getting caught or perceived? The answers in the shift of STATUS QUO & the evolution of paradigm in which your work you worked so hard for wouldnbe simply overridden & back to the square one. In short; can you patent it? NO. The rest is obvious.
