In- and Out-Groups01:31

In- and Out-Groups

44.0K
People all belong to a gender, race, age, and social economic group. These groups provide a powerful source of our identity and self-esteem (Tajfel & Turner, 1979) and serve as our in-groups. An in-group is a group that we identify with or see ourselves as belonging to.

Deindividuation00:57

Deindividuation

31.1K
Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

Social Foundations of Self II: The Generalized Other

341
According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group...

Group Polarization01:01

Group Polarization

39.3K
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.

Robbers Cave

14.9K
During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

Stereotype Threat and Self-fulfilling Prophecies

43.1K
When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...

Summary
This summary is machine-generated.

People are less kind to their future selves if they anticipate joining an opposing group. This suggests that intergroup bias influences intertemporal choices, impacting future decision-making.

Area of Science:

  • Social Psychology
  • Behavioral Economics
  • Decision Science

Background:

  • Interpersonal behavior is strongly influenced by in-group favoritism.
  • It remains unclear if this bias extends to how individuals treat their future selves.

Purpose of the Study:

  • To investigate whether individuals extend in-group favoritism to their future selves.
  • To determine if anticipated group membership influences intertemporal choices.

Main Methods:

  • Two studies were conducted with participants engaged in an emotionally charged debate.
  • Participants were assigned to conditions where they expected to remain in their current group or join the opposing group.

Main Results:

  • Participants expecting to join the opposing group showed reduced willingness to sacrifice for their future selves.
  • These participants treated their future selves with less kindness, similar to how they treated strangers.
  • An unpleasant task was more likely to be left for their future selves.

Conclusions:

  • The principles governing interpersonal behavior, including in-group bias, appear to extend to intertemporal decision-making.
  • Findings suggest potential strategies for promoting more prudent future-oriented decisions.
