Psionics involve the use of the mind to alter or command reality, typically through some understanding of a deeper truth about the universe or command over a fundamental law of reality.
It’s pretty cool, but I have trouble thinking of media where it takes a prominent role. The few examples that come to mind are:
Star Wars - The Force Mass Effect - Biotics/Element Zero technology Stellaris - Spiritualist Ethos Warhammer 40k - Psykers/Orks
What are some other examples of psionics in Sci-Fi?
“More Than Human” by Theodore Sturgeon is a novel about a collective of psionic humans who have to work together because they have an unusual mix of powers and weaknesses. One of them is a forever-infant whose role is a living supercomputer, for example
“Ishmael” by Daniel Quinn is a bit of a stretch, but it’s technically a conversation between the main character and a telepathic gorilla, if you want something a little different than the usual story about psychic humans
On the movie side, there’s “Beyond the Black Rainbow,” a somewhat trippy thriller and sort-of horror story about a psychic adolescent girl being raised by a scientist who developed a disturbing obsession with her. Might be a little rough to watch on that note, but it’s good. I liked the way they portrayed how her powers worked and it was an interesting audio-visual experience besides
