Social Traps01:41

Social Traps

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 more cows, the larger...
Group Polarization01:01

Group Polarization

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.
Impact of Social Context on Individuals01:21

Impact of Social Context on Individuals

Social psychology examines how the real or imagined presence of others influences individuals' thoughts, feelings, and behaviors. A key concept in this field is the role of social context in shaping behavior. The same individual may act differently depending on the social setting, due to the varying expectations and norms associated with each environment. This context-dependent behavior illustrates the influence of social roles, which prescribe appropriate conduct in specific situations.Social...

Impression Management Techniques III: Aligning Actions

Aligning actions are communicative strategies individuals employ to maintain social harmony and preserve personal identity in the face of potential disruptions to social norms. These actions are particularly important in managing social impressions when one's behavior might be seen as inappropriate, incompetent, or morally questionable.Types of Aligning ActionsThe three principal types of aligning actions are disclaimers, accounts, and apologies.DisclaimersDisclaimers are preventive; they are...
Bystander Effect02:09

Bystander Effect

The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.
Social Foundations of Self IV: Self in Digital Communication01:30

Social Foundations of Self IV: Self in Digital Communication

Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...

Area of Science:

  • Computer Science
  • Social Computing
  • Network Science

Background:

  • The World Wide Web enables large-scale collective action.
  • Social mobilization is a key area of research.
  • Previous methods for large-scale coordination were limited.

Purpose of the Study:

  • To explore the World Wide Web's potential for social mobilization.
  • To test a novel recursive incentive mechanism for task completion.
  • To win the Defense Advanced Research Projects Agency (DARPA) Network Challenge.

Main Methods:

  • The study involved locating 10 red weather balloons across the continental United States.
  • A recursive incentive mechanism was employed to disseminate information and motivate participation.
  • The team's performance was compared against theoretical models and other approaches.

Main Results:

  • The implemented recursive incentive mechanism successfully located all 10 balloons in less than 9 hours.
  • This approach proved highly effective in achieving rapid and large-scale social mobilization.
  • The mechanism demonstrated both theoretical soundness and practical efficacy.

Conclusions:

  • Recursive incentive mechanisms are a powerful tool for large-scale online mobilization.
  • The study validates the potential of the World Wide Web for complex, time-sensitive tasks.
  • This approach offers a scalable solution for future crowd-sourced challenges.
