Tested, indistinguishable from clairvoyance

Telepathy

Telepathy is the claimed ability of transferring thought directly between minds. It has been tested — The same ganzfeld protocol as clairvoyance; the two are not separated experimentally. Shares both the positive meta-analysis and the failed replication. No experiment has ever distinguished telepathy from clairvoyance, because in the design there is nothing to distinguish.

Where the word comes from

Coined in 1882 by Frederic Myers, founder of the Society for Psychical Research — the same year the Society itself was founded.

Terms in this field are younger than they sound. Most were coined between 1840 and 1930, in the Spiritualist and Theosophical revivals, and then presented as ancient. Dating them is the cheapest reality check available.
