150 Years of the word Pareidolia

The term pareidolie was introduced by the German psychiatrist, Karl Ludwig Kahlbaum in articles published in 1865[1] and 1866[2].

Then, in an 1867 British medical journal article reviewing Dr. Kahlbaum’s article (The Journal of Mental Science, Volume 13)[3], the German word Pareidolie was translated into English as pareidolia. Although the word is rarely found in general dictionaries, it has a long history in psychiatry.

Pareidolia has been getting more popular lately with it being added to dictionaries as recent as February 2017 – specifically the Merriam-Webster dictionary!

pareidolia

  1. :  the tendency to perceive a specific, often meaningful image in a random or ambiguous visual pattern

Around here we prefer the word Extractionism to pareidolia  – which has a leaning towards this as an error in seeing.
