Patternicity

The tendency to see patterns where none exist.
What it is
Seeing faces in clouds or links between unrelated events is a common feature of perception. One account holds that the tendency persists because missing a real pattern was once costlier than a false alarm. In experiments by Jennifer Whitson and Adam Galinsky, the research term is illusory pattern perception, and people made to feel a lack of control showed more of it.
In effect
In the article on why people believe conspiracy theories, it is the perceptual habit that conspiracy explanations draw on.
What it does not say
It is a general tendency, not a flaw in particular people. Seeing patterns is also how people find real ones.
