Social Proof00:52

Social Proof

29.0K
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.

Reason and Intuition

7.0K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

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...

Cognitivism

2.2K
Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

Self Within Cultural Contexts

9
Cultural frameworks for understanding the self are often categorized into two broad orientations: individualism and collectivism. These paradigms influence how people define themselves, relate to others, and interpret their social worlds. Each orientation offers distinct perspectives on autonomy, responsibility, and the role of the individual within a community.Individualistic CulturesIn individualistic cultures like North America and Western Europe, identity is understood as autonomous and...

Groupthink01:34

Groupthink

45.9K
When in group settings, we are often influenced by the thoughts, feelings, and behaviors around us. Groupthink is another phenomenon of conformity where modification of the opinions of members in a group aligns with what they believe is the group consensus (Janis, 1972). In such situations, the group often takes action that individuals would not perform outside the group setting because groups make more extreme decisions than individuals do. Moreover, groupthink can hinder opposing trains of...

Area of Science:

  • Cognitive Science
  • Social Psychology
  • Philosophy of Mind

Background:

  • Human rationality is often studied at the individual level.
  • Collective decision-making, such as voting, introduces complexities regarding belief rationality.
  • Assessing group beliefs presents unique challenges compared to individual assessments.

Purpose of the Study:

  • To explore the implications of collective decision-making on human rationality, particularly concerning beliefs.
  • To examine how individual rational strategies may yield unexpected outcomes in collective contexts.
  • To introduce formal frameworks for evaluating the epistemic norms of collectives.

Main Methods:

  • Illustrative examples of collective rationality challenges.
  • Overview of formal frameworks for assessing collective beliefs.
  • Integration of simulations with formal frameworks to study epistemic norms.

Main Results:

  • Individual rationality does not always translate to collective rationality.
  • Formal frameworks can reveal divergences in rationality assessments between individuals and groups.
  • Simulations demonstrate the utility of formal models in understanding collective epistemic norms.

Conclusions:

  • Collective rationality, especially regarding beliefs, is a significant area of inquiry.
  • Understanding group belief dynamics requires specialized formal approaches.
  • Formal frameworks and simulations are essential tools for elucidating collective epistemic norms.
