Cognitive complexity describes cognition along a simplicity-complexity axis. It is the subject of academic study in fields including personal construct psychology, organisational theory and human-computer interaction.

Cognitive complexity is a psychological characteristic or psychological variable that indicates how complex or simple is the frame and perceptual skill of a person. A person who is measured high on cognitive complexity tends to perceive nuances and subtle differences which a person with a lower measure, indicating a less complex cognitive structure for the task or activity, does not.
Cognitive complexity can have various meanings:
- the number of mental structures we use, how abstract they are, and how elaborately they interact to shape our perceptions.
- "an individual-difference variable associated with a broad range of communication skills and related abilities ... [which] indexes the degree of differentiation, articulation, and integration within a cognitive system".
In computer science
In artificial intelligence
In an attempt to explain how humans perceive relevance, Cognitive complexity is defined as an extension of the notion of Kolmogorov complexity. It amounts to the length of the shortest description available to the observer. Here is an example : Individuating a particular Inuit woman among one hundred people is simpler in a village in Congo rather than in an Inuit village.
Cognitive complexity is related to probability (see Simplicity theory): situations are cognitively improbable if they are simpler to describe than to generate. Human individuals attach two complexity values to events:
- description complexity (see above definition)
- generation complexity: the size of the minimum set of parameter values than the 'world' (as imagined by the observer) needs to generate the event.
To 'generate' an event such as an encounter with an Inuit woman in Congo, one must add up the complexity of each event in the causal chain that brought her there. The significant gap between both complexities (hard to produce, easy to describe) makes the encounter improbable and thus narratable.
