A term coined by science-fiction editor John W. Campbell,
Jr. to denote a combination of radionics and psi phenomena.
His editorial ‘‘The Science of Psionics,’’ published in the February
1956 issue of his magazine Astounding Science Fiction, discussed
‘‘psychic electronic machines.’’ One such machine was
invented by Thomas G. Hieronymus (U.S. Patent No.
2,482,773) and resembles the black box of radionics. Campbell
described the machine in an article later that year. Campbell
is also remembered as the publisher of L. Ron Hubbard’s initial
article introducing Dianetics to the public.

Science Fiction (June 1956).
