Summary
Low-cost punishment and gossip deter free-riding in human communities. Language, a basic adaptation, likely explains human sociality better than moralistic aggression.
Area of Science:
- Evolutionary anthropology
- Social psychology
Background:
- Free-riding poses a challenge to cooperation in human communities.
- Social mechanisms are crucial for maintaining cooperation.
Purpose of the Study:
- To examine the role of low-cost punishment and gossip in deterring free-riding.
- To evaluate the evolutionary basis of human sociality, contrasting language with moralistic aggression.
Main Methods:
- Analysis of social dynamics in small human communities.
- Theoretical evaluation of evolutionary adaptations for sociality.
Main Results:
- Low-cost punishment is identified as a primary mechanism against free-riding.
- Human susceptibility to gossip acts as a complementary social control.
- The adaptation of language is proposed as a sufficient explanation for human sociality.
Conclusions:
- Sociality in humans can be explained by basic adaptations like language and social control mechanisms.
- Alternative explanations, such as moralistic aggression, may not be necessary to account for human cooperation.

03:20The Stanford Prison Experiment
The famous and controversial Stanford Prison Experiment, conducted by social psychologist Philip Zimbardo and his colleagues at Stanford University, demonstrated the power of social roles, social norms, and scripts.
00:57Deindividuation
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.
02:20Milgram's Obedience to Authority
Obedience to authority is classically demonstrated in a more famous series of social psychology experiments performed by Stanley Milgram. He was a social psychology professor at Yale who was influenced by the trial of Adolf Eichmann, a Nazi war criminal. Eichmann’s defense for the atrocities he committed was that he was “just following orders.”
02:04Bullying
A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is bullying.
01:38Cognitive Dissonance
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
01:41Social 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...
