Trying to find the name of a book or series from the 60s/70s about the future when mankind had spread to multiple planets outside of this solar system - and the government (a little totalitarian) was monitoring kids who looked up psychic abilities/stories in their local library. I remember the color purple had something to do with the story/psychics and that they (psychics) came in different levels/strengths and were perceived as a potential threat to those in power if they weren't monitored/controlled.
Second short story was from an old sci fi master about a 'nobody' who wanted to teach others telekinesis not just the favored/born with it who lorded this ability/their talent and associated riches over others/normal folks. He used the power to teach others in a giant stadium to show that the power could be given to others outside of those showing at birth/puberty.
