Egoism and Altruism01:55

Egoism and Altruism

Voluntary behavior with the intent to help other people is called prosocial behavior. Why do people help other people? Is personal benefit such as feeling good about oneself the only reason people help one another?
Altruism01:03

Altruism

Altruistic behaviors are “unselfish” behaviors—those that help another individual at the expense of the individual carrying out the behavior. Despite the negative consequences for the altruistic animal, these behaviors are thought to have evolved for several reasons.
Self-Discrepancy Theory02:45

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.
Empathy02:34

Empathy

Some researchers suggest that altruism operates on empathy. Empathy is the capacity to understand another person’s perspective, to feel what he or she feels. An empathetic person makes an emotional connection with others and feels compelled to help (Batson, 1991). Empathy can be expressed in several ways, including cognitive, affective, and motor.
Inclusive Fitness00:57

Inclusive Fitness

Most altruistic behavior—in which one animal helps another at a cost to themselves—occurs between relatives. Scientists think these altruistic behaviors evolved because they increase the inclusive fitness of the animal providing help.
Self-Serving Bias01:29

Self-Serving Bias

Self-serving bias is a cognitive phenomenon in which individuals attribute positive outcomes to internal factors such as their abilities, intelligence, or effort while attributing negative outcomes to external circumstances. This cognitive distortion helps maintain self-esteem but can also impede objective self-assessment.Theoretical Explanations of Self-Serving BiasTwo primary theories explain the self-serving bias: the cognitive explanation and the motivational explanation.The cognitive...

Area of Science:

  • Evolutionary Biology
  • Psychology
  • Behavioral Science

Background:

  • Traditional evolutionary theory often emphasizes self-interest.
  • The prevalence of altruistic and unselfish behaviors presents a challenge to purely self-interested models.
  • Understanding the origins of cooperation is crucial for explaining social structures.

Purpose of the Study:

  • To provide a comprehensive framework for understanding the evolution of unselfish behavior.
  • To integrate psychological mechanisms with evolutionary theory.
  • To challenge the notion that evolution inevitably leads to selfishness.

Main Methods:

  • Synthesizing research from evolutionary biology, psychology, and philosophy.
  • Developing theoretical models of multilevel selection.
  • Analyzing empirical evidence for altruism across different species and social contexts.

Main Results:

  • Demonstrates that natural selection can operate at multiple levels (gene, individual, group).
  • Identifies psychological mechanisms that facilitate unselfish behavior, such as empathy and group loyalty.
  • Provides evidence that altruism is not an anomaly but a product of evolutionary processes.

Conclusions:

  • Unselfish behavior is a significant and explainable outcome of evolution.
  • Both individual and group selection play roles in shaping altruism.
  • A unified understanding of evolution and psychology is necessary to fully grasp unselfishness.
