Adaptive Cognition

Adaptive cognition is the study of how cognitive processes — perception, memory, reasoning, decision-making — are shaped by the pressures of biological evolution and ecological context. The core thesis is that cognition is not a general-purpose reasoning engine but a collection of specialized mechanisms, each calibrated to solve recurrent problems faced by ancestral organisms. This framework stands in explicit opposition to the view that human cognition is best modeled as a domain-general, bias-free rational agent: adaptive cognition explains why organisms are systematically irrational in some domains and systematically reliable in others, depending on whether the domain matches the ancestral environment in which the cognitive mechanism evolved. Key concepts include ecological rationality, evolved psychological mechanisms, and the distinction between cognitive mechanisms and cognitive biases — a distinction that dissolves once one recognizes that most 'biases' are adaptive heuristics operating outside their domain of calibration.
