Overview

Why this framework exists

The Evolved Psychological Mechanisms Framework provides a structure for understanding how psychological mechanisms have evolved to solve specific adaptive problems. It emphasizes the importance of considering the evolutionary history of a species when studying its behavior and cognition. The framework also highlights the role of learning and culture in shaping human behavior, while acknowledging that these factors are ultimately influenced by evolved psychological mechanisms.

Core principles

3 total
  1. Evolved psychological mechanisms are specialized to solve specific adaptive problems.
  2. Learning and culture are influenced by evolved psychological mechanisms.
  3. The human mind is composed of multiple evolved psychological mechanisms that interact and influence one another.

Steps

3 steps
  1. Identify the adaptive problem
    Determine the specific adaptive problem that the psychological mechanism has evolved to solve. This requires an understanding of the evolutionary history of the species and the selective pressures that have shaped its behavior and cognition.
    Pro tipConsider the environment in which the species evolved and the challenges it faced.
    WarningBe careful not to assume that a psychological mechanism has a single, simple function.
  2. Analyze the mechanism's design features
    Examine the specific design features of the psychological mechanism, such as its input, processing, and output components. This requires an understanding of the mechanism's functional architecture and how it is influenced by learning and culture.
    Pro tipConsider how the mechanism is calibrated to respond to specific cues or stimuli.
    WarningBe careful not to oversimplify the mechanism's design features or assume that they are fixed.
  3. Test the mechanism's functional hypotheses
    Develop and test functional hypotheses about the psychological mechanism, using a range of methods such as comparative analysis, cross-cultural research, and physiological measures. This requires an understanding of the mechanism's adaptive function and how it is influenced by evolutionary pressures.
    Pro tipConsider using multiple methods to test the mechanism's functional hypotheses.
    WarningBe careful not to assume that a single study or finding is definitive.

Examples

2 cases
Incest avoidance

The evolved psychological mechanism for incest avoidance is an example of a mechanism that has evolved to solve a specific adaptive problem. It is influenced by learning and culture, but its adaptive function is ultimately determined by evolutionary pressures.

OutcomeThe mechanism helps to prevent inbreeding and promote genetic diversity.
Food aversion

The evolved psychological mechanism for food aversion is an example of a mechanism that has evolved to solve a specific adaptive problem. It is influenced by learning and culture, but its adaptive function is ultimately determined by evolutionary pressures.

OutcomeThe mechanism helps to prevent the consumption of toxic or harmful substances.

Common mistakes

3 traps
Oversimplifying the mechanism's design features
Failing to consider the complexity and nuance of the psychological mechanism's design features can lead to oversimplification and a lack of understanding of its adaptive function.
Assuming a single, simple function
Assuming that a psychological mechanism has a single, simple function can lead to a lack of understanding of its adaptive complexity and the range of selective pressures that have shaped its evolution.
Failing to consider the role of learning and culture
Failing to consider the role of learning and culture in shaping human behavior can lead to a lack of understanding of the psychological mechanism's adaptive function and its interaction with other mechanisms.

Origin story

How this framework came to be

The Evolved Psychological Mechanisms Framework has its roots in the field of evolutionary psychology, which emerged in the 1980s. It is based on the idea that the human mind is composed of evolved psychological mechanisms that have been shaped by natural selection to solve specific adaptive problems. The framework has been developed and refined by researchers such as David Buss, Leda Cosmides, and John Tooby.
