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.
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?
Ethical Dilemmas II01:30

Ethical Dilemmas II

Resolving an ethical dilemma in healthcare involves a systematic approach that considers every aspect of the issue, respecting both the patient's needs and values and the healthcare professional's ethical obligations. Here are potential steps to resolve an ethical dilemma:
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...
Ethical Dilemmas I01:17

Ethical Dilemmas I

Ethical dilemmas in nursing are of utmost importance, as they often arise from the tension between adhering to core ethical principles and the practical realities of healthcare delivery. These dilemmas require nurses to navigate complex situations where competing ethical considerations pull them in different directions.
Let us explore some examples to understand the potentially complex moral decisions nurses face.
Take the case of caring for minors, particularly in areas related to reproductive...
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.

Resumen

La teoría de la aptitud inclusiva de Hamilton explica el altruismo y el despecho. Investigaciones recientes aclaran los debates sobre el altruismo extremo, la existencia del rencor y el altruismo del gen de la barba verde en diversos organismos.

Área de la Ciencia:

  • Biología evolutiva Biología evolutiva.
  • Ecología del comportamiento Ecología del comportamiento.

Sus antecedentes:

  • La teoría de la aptitud inclusiva de Hamilton proporciona un marco para comprender el altruismo y el despecho.
  • Varios debates clave con respecto a la evolución de estos comportamientos siguen sin resolverse.

  • Resolvió el debate sobre si el altruismo extremo (por ejemplo, los trabajadores sociales de insectos) está impulsado por la genética o la ecología.
  • Proporcionó evidencia de la existencia de despecho en las poblaciones naturales.
  • Se aclararon las condiciones bajo las cuales el altruismo puede evolucionar entre no parientes a través de genes de "barba verde".

    • Conclusiones:

    • El trabajo reciente ha avanzado significativamente en la comprensión del altruismo y el rencor.
    • La teoría de Hamilton está robustamente apoyada por diversas evidencias empíricas.
    • Se han resuelto los principales debates evolutivos, vinculando la teoría a los fenómenos observables.
