Foundations of Human Sociality

When I was working with Institute for the Future on what we called "the cooperation project," we recognized that insights regarding human cooperation were fragmented among different disciplines that were often unaware of converging work. So we created these summaries. My original vision, which was not implemented, was to arrange these resources on a visual clickable digital map: Hover over a node and a one sentence summary pops up; hold mouse down and a one paragraph summary pops up; click through to see the entire summary.

I saw the map as a collaboration tool, enabling annotation and embedded video.

Title:  Foundations of Human Sociality (Introduction and Overview)
Oxford University Press, 2004
URL:  https://academic.oup.com/book/8134

Authors: Robert Boyd, Samuel Bowles, Colin Camerer,  Ernst F. Fehr, Herbert, Herbert Gintis,  Joseph Henrich, Richard McElreath


Findings:

  • People are willing to reward fairness and reciprocity and punish those who do not act pro-socially, even at cost to themselves.

  • Group-level differences in behavior proved to be greater than  individual-level differences, indicating cooperative behavior might be  more embedded in cultural conditions than was previously thought.  While  one culture might take advantage of a person who is too altruistic,  another might exclude a person for being too self-interested.

One Sentence:

Experiments like the Ultimatum  Game and the Public Goods Game (one shot games for real money divided  among strangers) that have been conducted in different countries all  over the world have shown that group behavior frequently does not fit  the traditional model of self-interested actors, that it is too richly  varied between cultures to support a universal sense of fairness, and  that a higher degree of market integration and higher payoffs to  cooperation can be linked to greater levels of prosocial behavior.

One Paragraph:

The  self-regarding and outcome oriented picture of human behavior presented  in traditional economics does not explain why humans care so much about  each other and about how social interaction is carried out, not just  the end goals.  The Ultimatum Game, designed by Werner Guth, is just one  illustration of how real people will not always follow the dictates of  self-interested rationality.  Two subjects are given a sum of money, one  is given the power to divide the sum, and the other can either accept  or reject (in which case neither get any money).  Research from  conducting hundreds of trials of the game with thousands of students in  Europe, Japan and the USA has shown that the responders frequently  reject low offers and proposers frequently propose near equal divisions,  even though it is to their monetary disadvantage.  While early  experiments on undergraduates seemed to suggest that there was a  universal sense of fairness, extended research in different cultures  (hunter-gatherers, slash-and-burn agriculturists, nomadic pastoralists)   has exposed much cultural variation in responses, indicating that local  cultural conditions play an important role in how people approach  cooperation.

While mean proposals for university students from all over the world  was usually between 42 and 48 percent, mean proposals from this  cross-cultural study varied from 25 to 57 percent.  Rejection rates, the  action of the responders, also varied considerable between groups.   Individual-level economic and demographic variables did not explain  behavior as well as group-level behavior, and game play often could be  connected to the people's common patterns of interaction.  For example,  the Orma recognized that one of the experiment's games was similar to  the harambee, a local institution of giving to public goods like roads  and schools.  They began calling it 'the harambee game' and displayed  highly prosocial behavior.  In other groups, like the Au and Gnau,  frequent rejection of generous offers can be explained by a cultural  association with gift-giving: accumulating gifts, even if unsolicited,  can imply a lowered status and force the receiver into future  obligations or political alliance.  The cross-cultural study showed  that, in the case of groups at the extremes of behavior, "contrasting  behaviors seem to reflect their differing patterns of everyday life, not  any underlying logic of hunter-gatherer life ways."

The effect of market integration on cooperation to obtain a monetary  reward can be explained easily: individuals from market-oriented  societies when put in the context of one of the games are able to seek  analogues in their daily activities of using and trading money with  strangers.  "Those who do not customarily deal with strangers in  mutually advantageous ways may be more likely to treat anonymous  interactions as hostile or threatening, or as occasions for the  opportunistic pursuit of self-interest."
