I guess that it is a matter of view as to how you view Psionics. Aside from telepathy, there is a lot in psionics that I view as indistinguishable from magic.
So, magic as in Clark's (3rd?) law: "Any sufficiently advanced technology is indistinguishable from magic."
As of about 1890 or so, scientists believed they were getting close to understanding the universe. They had Dalton's atomic theory, they'd developed a periodic table, they were making advances in understanding the atom's role in chemistry. They believed that elements were unchangeable, atoms indivisible. There was no concept of fission, fusion, or nuclear radiation, no idea of atomic nuclei build up from smaller building blocks, not so much as a hint of the subatomic world other than the great mystery of how the sun managed to produce all that energy (and maybe the occasional inexplicable illness, but this was an era when a lot of illness was still inexplicable).
Then someone noticed odd effects when photographic plates were in the presence of certain elements, and all bets were off.
As near as we can tell, psionics is as hokum as it comes. It doesn't seem to survive the close scrutiny of science. Evidence under rigorous testing methods has bordered between equivocal and nonexistent. No known or suspected aspect of physics predicts people manipulating the universe or exchanging information by mind alone. We've made greater strides in understanding why some people believe in psionics - some neurological processes like to play tricks on us

- than we have in identifying any real psionics.
However, it's a persisting topic of science fiction and many still believe (on little more than hope, apparently) that it's possible. If it is - if some aspect of scientific scrutiny has been inadvertently quashing it all these years - then it may be as it was with nuclear radiation: an unpredicted, previously unknown, and entirely new kind of physics, based on processes and mechanisms we can't even make an educated guess about, 'cause nothing we currently know indicates it's even real, much less detectable by current tools. In essence, from the view of current science, it's magic.
