Automatic Writing

Automatic Writing (自動書記) is writing in which what is written is produced from a subconscious, and/or external and/or spiritual source without conscious awareness of the content. Although also called as Psychography, which can refer to an esper power, Automatic Writing is always referred to in the series as part of magic.

Etymology
In the series, Automatic Writing uses the same kanji with Index's John's Pen Mode, but is to be read differently. The kanji for John's Pen Mode, should be translated as Automatic Secretary, rather than Automatic Writing, as to fit with the fact that Index's mind becomes "hijacked."

Kazakiri Hyouka Arc
The only time Automatic Writing is used is when Sherry Cromwell is searching for an important target in Academy City. She uses Automatic Writing to write the names of one of her targets, which spells out the kanji of Kazakiri Hyouka's name. Sherry is however, surprised by what she written, as she does not understand what she just wrote, but nonetheless, commands her golem to search for the person who has that name.

Aleister Crowley Arc
In a flashback of Aleister Crowley's past, Samuel Liddell MacGregor Mathers of the Golden Dawn utilizes this to communicate with Aleister Crowley immediately after he attacked the Isis-Urania Temple in Blythe Road to steal the treasure the magic cabal kept there.
