Group Polarization01:01

Group Polarization

37.5K
Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

Social Exchange Theory

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).

This theory suggests that individuals engage in relationships to gain benefits and reduce burdens, similar to economic transactions. It has been widely applied to various types of relationships, including romantic, professional, and social interactions.Rewards and Costs in RelationshipsRelationship rewards include emotional...

Relationship Formation

43.8K
What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Factors Influencing Attraction I: Proximity

96
Proximity plays a fundamental role in shaping interpersonal attraction by increasing opportunities for interaction and fostering familiarity. Research consistently demonstrates that individuals are more likely to form social bonds with those who are physically closer to them, whether in residential settings, workplaces, or educational institutions. This effect is largely driven by the increased frequency of encounters, which facilitates the development of friendships and romantic...

Area of Science:

  • Political Psychology
  • Computational Social Science
  • Social Network Analysis

Background:

  • Americans exhibit strong social connections within their political parties.
  • Confounding factors often obscure whether partisanship itself drives social tie formation.
  • Understanding the role of partisanship in online social networks is crucial.

Purpose of the Study:

  • To experimentally determine the causal effect of shared partisanship on social tie formation.
  • To investigate this effect within an ecologically valid social media environment (Twitter).

Main Methods:

  • Creation of bot accounts identifying with either the Democratic or Republican party.
  • Bots varied in the strength of their stated partisan identification.
  • Random assignment of 842 Twitter users to be followed by these bots.

Main Results:

  • Users were approximately three times more likely to reciprocally follow-back bots matching their own partisanship.
  • This effect was consistent regardless of the bot's strength of partisan identification.
  • No significant partisan asymmetry was observed; both Democrats and Republicans showed preferential follow-back behavior.

Conclusions:

  • Shared partisanship exerts a strong causal influence on the formation of social ties in online settings.
  • Findings highlight the role of political identity in shaping social media interactions.
  • Results have implications for understanding political polarization and social dynamics in the U.S.
