Social Proof

32.4K
Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Social Scripts

10.3K
People tend to know what behavior is expected of them in specific, familiar settings. A script is a person’s knowledge about the sequence of events expected in a specific setting (Schank & Abelson, 1977). Essentially, scripts are a particular kind of schema, one containing default values for the features within an event. In the restaurant example, the script's features include the props (e.g., tables, menu, food, and money), the roles to be played (e.g., customer and waiter),...

Social Traps01:41

Social Traps

26.9K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Social Exchange Theory

40.8K
We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

The Sense of Self: Reflected Self-Appraisal and Social Comparison

56.1K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Social Facilitation01:04

Social Facilitation

36.6K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Summary

Preference-based social welfare functions (pbSWF) offer a superior method for balancing personal and social objectives compared to standard multi-criteria decision analysis (MCDA). This approach respects individual judgments and ethical principles, enhancing social welfare analysis.

Area of Science:

  • Decision Analysis
  • Social Welfare Economics
  • Health Economics

Background:

  • Traditional Multi-Criteria Decision Analysis (MCDA) methods often struggle to reconcile competing personal and social goals.
  • There is a need for approaches that respect individual autonomy and align with ethical principles in social welfare evaluation.

Purpose of the Study:

  • To introduce and advocate for Preference-based Social Welfare Functions (pbSWF) as a more effective tool for social welfare analysis.
  • To highlight the advantages of pbSWF over standard MCDA in reconciling diverse objectives.

Main Methods:

  • Utilizing micro-econometric data to capture personal preferences for health, wealth, and other life benefits.
  • Employing surveys to assess public acceptance of ethical axioms and levels of inequality aversion.

Main Results:

  • Preference-based social welfare functions (pbSWF) demonstrate superior performance in balancing personal and social goals.
  • Discrepancies between MCDA objective functions and pbSWF indicate potential failures in respecting non-paternalism and ethical principles.

Conclusions:

  • Preference-based social welfare functions (pbSWF) provide a robust framework that respects individual autonomy (non-paternalism) and ethical considerations.
  • The pbSWF approach is practical and can be implemented using empirical economic and survey data for improved social welfare assessments.
