After a week of research, the only thing concrete I can find was scientists developed a test where a machine powered by a radioactive source produced numbers at random. By instructing participants to will the number to change up or down, the results were changed at a trillion:1 rate of possibility.
Therefore, these fake-psy exercises where you have to guess the number aren't training at all, they're exploiting a phenomenon. Every youtube person I've seen that teaches you to exercise such abilities is a complete hoaxer, of those I've seen, and a lot of faggy little snowflakes that wish they were psychic to stop getting beats.
There are strange phenomenon where people intuitively know the future, know when a family member dies and where, and other things, but I have not found anyone that can describe it in an obersvable, reproducible manner, and no one serious whose even tried to train the public.
I am highly interested if anyone figures anything out, the INFJ personality thing from the shrinks helped me figure out myself even more than the kaballah astrology thing, but there are still many questions.
