Strategies of Self-Presentation I: Strategic Self-Presentation01:12

Strategies of Self-Presentation I: Strategic Self-Presentation

7
Strategic self-presentation refers to individuals' intentional efforts to influence how others perceive them. This process is employed in various social and professional settings, such as job interviews, dating, politics, and legal contexts, where individuals seek to shape impressions to gain social or material advantages. While people generally present themselves in ways that align with their authentic characteristics, external factors, such as cognitive load, can hinder their ability to...

Theory of Attribution II: Kelley's Covariation Theory

15
Attribution theory plays a crucial role in social psychology, helping to explain how individuals interpret the causes of behavior. One prominent model within this field is Harold Kelley's covariation theory, which provides a systematic approach to determining whether internal traits or external circumstances drive a person's actions. The model posits that individuals rely on three key types of information—consensus, consistency, and distinctiveness—to make these judgments.Consensus:...

The Two-State Receptor Model01:29

The Two-State Receptor Model

2.5K
The two-state receptor model explains a drug's interaction with receptors, such as G protein-coupled receptors and ligand-gated ion channels, to induce or inhibit a biological response. When no natural ligands are present, a receptor exists in an equilibrium of inactive (Ri) and active (Ra) conformations. The inactive form does not produce a response, while the active form generates a basal effect known as constitutive activity.
The binding affinity of a drug determines its interaction with...

Unrealistic Optimism Bias01:30

Unrealistic Optimism Bias

9
Unrealistic optimism bias is the tendency to overestimate the likelihood of positive outcomes. This cognitive bias makes individuals believe they are less likely to experience failures, setbacks, or risks and more likely to succeed than others. For example, people may assume they are less prone to health issues, accidents, or financial struggles than their peers, even when they share similar risk factors.One key component of this bias is the above-average effect, where individuals perceive...

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.

Naturalistic Observations02:30

Naturalistic Observations

16.4K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Summary

This study critiques Matthias Egg's "effective realism," arguing it is too inclusive by examining its application to Newtonian and quantum mechanics. The research suggests a need for more precise ontological commitments in scientific realism.

Area of Science:

  • Philosophy of Science
  • Quantum Mechanics
  • Classical Mechanics

Background:

  • Scientific realism faces challenges reconciling with quantum mechanics' underdetermination.
  • Matthias Egg (2021) proposed 'effective realism' to address this by focusing on effective ontology.
  • The concept of 'effective ontology' aims to reconcile scientific realism with quantum mechanics.

Purpose of the Study:

  • To critically evaluate Matthias Egg's proposed 'effective realism'.
  • To demonstrate that 'effective realism' is ontologically overly promiscuous.
  • To illustrate the ontological issues using examples from Newtonian and quantum mechanics.

Main Methods:

  • General philosophical argumentation.
  • Conceptual analysis of 'effective ontology'.
Keywords:
Effective ontologyMatthias EggQuantum mechanicsScientific realism

  • Application of critique to established physical theories (Newtonian and quantum mechanics).

    • Main Results:

    • Egg's 'effective realism' is shown to be ontologically promiscuous.
    • The proposed reconciliation of scientific realism with quantum mechanics via 'effective ontology' is found problematic.
    • The critique is illustrated through specific examples in both classical and quantum physics.

    Conclusions:

    • 'Effective realism' as currently formulated is ontologically too permissive.
    • Reconciling scientific realism with quantum mechanics requires a more constrained ontological approach.
    • Further refinement of realist commitments is necessary to adequately address foundational issues in physics.
