noun (also apophrenia)
(psychology) The perception of or belief in connectedness among unrelated phenomena.
[ From Wikipedia: "Coined in 1958 by Klaus Conrad, who defined it as the 'unmotivated seeing of connections' accompanied by a 'specific experience of an abnormal meaningfulness.'" There is some controversy over this word, as it comes from no known Greek root, whereas "apophrenia" could be considered a neologism taken from Greek apo- ("away from") and -phrenia (from phren, "mind"). Therefore, some consider apophenia a simple misspelling. Nevertheless, it seems to have become the popular usage. ]
The narrative of the movie A Beautiful Mind revolves around the protagonist’s apophenic beliefs. --Daily Writing Tips
