What is the supposed communication of thoughts or ideas by means other than the known senses called?

Telepathy (from the Greek τῆλε, tele meaning "distant" and πάθος/-πάθεια, pathos or -patheia meaning "feeling, perception, passion, affliction, experience") is the purported vicarious transmission of information from one person to another without using any known human sensory channels or physical interaction. The term was first coined in 1882 by the classical scholar Frederic W. H. Myers, a founder of the Society for Psychical Research (SPR), and has remained more popular than the earlier expression thought-transference.

Telepathy experiments have historically been criticized for lack of proper controls and repeatability. There is no good evidence that telepathy exists, and the topic is generally considered by the scientific community to be pseudoscience.
