Egoism and Altruism01:55

Egoism and Altruism

92.3K
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

41.7K
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.

Ethics and Bioethics01:22

Ethics and Bioethics

1.7K
Ethics is a philosophical study of moral actions. Ethics attempts to determine what is valuable for individuals and society. It examines the rational justification of moral judgments and analyzes what is morally just, fair, and right. Bioethics is a sub-discipline of applied ethics that analyzes the philosophical, social, and legal issues in life sciences and medicine. Ethical theories serve as a foundation for decision-making and represent the viewpoints from which people seek direction. They...

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.

Fundamental Attribution Error

13.3K
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...

Sensitivity, Specificity, and Predicted Value

In healthcare diagnostics, laboratory tests play a crucial role in identifying and diagnosing a wide range of medical conditions. However, interpreting test results is not always straightforward. An abnormal test result does not always confirm the presence of a disease, just as a normal result does not guarantee its absence. To assess the reliability of these diagnostic tools, healthcare practitioners rely on two key statistical indicators: sensitivity and specificity.
Sensitivity is the...

Summary

Institutions testing close contacts in the wider community, not just members, can reduce internal COVID-19 cases. An epidemiological model suggests allocating 45% of tests externally benefits institutions, even without full contact knowledge.

Area of Science:

  • Epidemiology
  • Public Health Modeling
  • Infectious Disease Dynamics

Background:

  • Institutions widely implemented internal testing during COVID-19 for safe reopening.
  • This inward-focused strategy overlooks community transmission and potential breaches.
  • An altruistic testing approach may offer greater protection.

Purpose of the Study:

  • To evaluate the effectiveness of community-focused testing versus institution-only testing.
  • To determine the optimal proportion of tests to allocate externally for institutional benefit.

Main Methods:

  • Developed an epidemiological model to simulate different testing strategies.
  • Assessed the impact of allocating a proportion of tests to community close contacts.
  • Analyzed results across various parameters including local prevalence and testing capacity.

Main Results:

  • Testing community close contacts consistently benefited institutions across all scenarios.
  • An optimal external testing allocation of 45% was identified under baseline parameters.
  • Optimal proportions ranged from 18% to 58% depending on specific conditions.

Conclusions:

  • Shifting testing resources to community contacts enhances institutional safety.
  • Even partial knowledge of community networks yields significant benefits.
  • Altruistic testing strategies are epidemiologically advantageous for institutions.
