Overview

Why this framework exists

Evolutionary Personality Psychology is a framework that explains how individual differences and species-typical mechanisms shape human personality and behavior.

Core principles

3 total
  1. Individual differences are adaptively patterned and reflect variable ancestral environments.
  2. Species-typical mechanisms shape human personality and behavior.
  3. The evolution of human personality and behavior is influenced by the interaction between individual differences and species-typical mechanisms.

Steps

3 steps
  1. Assess individual differences
    Assess individual differences, such as personality traits and behavioral tendencies, and understand how they are adaptively patterned.
    Pro tipConsider the use of personality assessments and behavioral observations to guide the assessment of individual differences.
    WarningFailure to assess individual differences can lead to suboptimal outcomes.
  2. Identify species-typical mechanisms
    Identify species-typical mechanisms, such as evolutionary adaptations and psychological mechanisms, and understand how they shape human personality and behavior.
    Pro tipConsider the use of evolutionary theory and psychological research to guide the identification of species-typical mechanisms.
    WarningFailure to identify species-typical mechanisms can lead to suboptimal outcomes.
  3. Understand the interaction between individual differences and species-typical mechanisms
    Understand the interaction between individual differences and species-typical mechanisms, and how they influence human personality and behavior.
    Pro tipConsider the use of evolutionary personality psychology theory to guide the understanding of the interaction between individual differences and species-typical mechanisms.
    WarningFailure to understand the interaction between individual differences and species-typical mechanisms can lead to suboptimal outcomes.

Examples

2 cases
The evolution of personality traits

Personality traits, such as extraversion and conscientiousness, may have evolved to solve specific adaptive problems, such as finding mates and achieving status.

OutcomeThe evolution of personality traits may have influenced the development of human personality and behavior.
The influence of species-typical mechanisms on human behavior

Species-typical mechanisms, such as the pursuit of status and the formation of romantic relationships, may have influenced the development of human behavior.

OutcomeThe influence of species-typical mechanisms on human behavior may have shaped the evolution of human personality and behavior.
