Apophenia () is the tendency to perceive meaningful connections between unrelated things.

The term ( from the ) was coined by psychiatrist Klaus Conrad in his 1958 publication on the beginning stages of schizophrenia. He defined it as "unmotivated seeing of connections [accompanied by] a specific feeling of abnormal meaningfulness". He described the early stages of delusional thought as self-referential over-interpretations of actual sensory perceptions, as opposed to hallucinations.

Apophenia has also come to describe a human propensity to unreasonably seek definite patterns in random information, which can occur in gambling.

Introduction

Apophenia can be considered a commonplace effect of brain function. Taken to an extreme, however, it can be a symptom of psychiatric dysfunction, for example as a symptom in paranoid schizophrenia, where a patient sees hostile patterns (for example a conspiracy to persecute them) in ordinary actions.

Apophenia is also typical of conspiracy theories, where coincidences may be woven together into an apparent plot.

Examples

Pareidolia

Pareidolia is a type of apophenia involving the perception of images or sounds in random stimuli.

A common example is the perception of a face within an inanimate object—the headlights and grill of an automobile may appear to be "grinning". People around the world see the "Man in the Moon". People sometimes see the face of a religious figure in a piece of toast or in the grain of a piece of wood. There is strong evidence that psychedelic drugs tend to induce or enhance pareidolia.

Pareidolia usually occurs as a result of the fusiform face area—which is the part of the human brain responsible for seeing faces—mistakenly interpreting an object, shape or configuration with some kind of perceived "face-like" features as being a face.

Gambling

Gamblers may imagine that they see patterns in the numbers that appear in lotteries, card games, or roulette wheels, where no such patterns exist. A common example of this is the gambler's fallacy.

Statistics

In statistics, apophenia is an example of a type I error – the false identification of patterns in data.

Synchronicity

Synchronicity can be considered synonymous with correlation, without any statement about the veracity of various causal inferences.

Patternicity

In 2008 Michael Shermer coined the word patternicity, defining it as "the tendency to find meaningful patterns in meaningless noise".

Clustering illusion

A clustering illusion is a type of cognitive bias in which a person sees a pattern in a random sequence of numbers or events. Many theories have been disproved as a result of this bias being highlighted.

One case, during the early 2000s, involved the occurrence of breast cancer among employees of ABC Studios in Queensland. A study found that the incidence of breast cancer at the studios was six times the rate in the rest of Queensland. An examination found no correlation between the heightened incidence and any factors related to the site nor any genetic or lifestyle factors of the employees.

Causes

Although there is no confirmed reason for why apophenia occurs, there are some respected theories.

Models of pattern recognition

Pattern recognition is a cognitive process that involves retrieving information either from long-term, short-term, or working memory and matching it with information from stimuli. There are three different ways in which this may happen and go wrong, resulting in apophenia.

Template matching

The stimulus is compared to templates, which are abstracted or partial representations of previously seen stimuli. These templates are stored in long-term memory as a result of past learning or educational experiences. For example, D, d, D, d, D and d are all recognized as the same letter.

Template-matching detection processes, when applied to more complex data sets (such as, for example, a painting or clusters of data) can result in the wrong template being matched. A false positive detection will result in apophenia.

Feature analysis

The stimulus is first broken down into its features and then processed. This model of pattern recognition says that the processing goes through four stages: detection, pattern dissection, feature comparison in memory, and recognition.

One of the most accredited studies in this field is Skinner's box. This experiment involved taking a hungry pigeon, placing it in a box and releasing food pellets at random times. The pigeon received a food pellet while performing some action; and so, rather than attributing the arrival of the pellet to randomness, the pigeon repeats that action, and continues to do so until another pellet falls. As the pigeon increases the number of times it performs the action, it gains the impression that it also increased the times it was "rewarded" with a pellet, although the release in fact remained entirely random.
