This article suggests a general theory of conflict and violence that may help explain the conditions under which internal conflict co-occur or are differentiated.

In this study, the authors analyze relationships between witchcraft accusations and the gender of the accused. They find that men are most often accused of witchcraft in their sample of 54 Bantu or Bantoid societies, and are particularly more likely to be accused of witchcraft by unrelated or blood-related individuals or in disputes over wealth or prestige. On the other hand, women are more likely to be accused of witchcraft in affinal relationships, particularly husbands and co-wives, and in situations related to fertility or relationships. Elderly women were also more likely to be accused of witchcraft than elderly men. The authors also examined outcomes of witchcraft accusations, finding that 81% of cases resulted in a negative outcome for the accused. They suggest that competition underlies accusations of witchcraft.

In this paper, the authors argue that polygyny creates social inequality in which economically advantaged men marry multiple women and economically disadvantaged men marry late in life or potentially never. The institution of polygyny results in a higher proportion of single men without families ("excess men"), who, the authors propose, may turn to violence to achieve higher wealth or prestige. Following this theory, the authors hypothesize that societies with more polygynous neighbors will be at higher risk for intergroup conflict, for which they find robust support. They also find that young men in polygynous societies, who are more likely to be economically disadvantaged and have less prestige, are also more likely to feel as though they are treated unequally and more ready to resort to violence, supporting the authors' theorized underlying mechanism.

This study examines how social structure, political organization, and intersocietal relations may affect the incidence of internal warfare (between culturally similar political communities). Results show that in uncentralized political systems, fraternal interest groups and unauthorized raiding parties may increase the incidence of internal war.

This article uses factor analysis to identify the key variables underlying the many cross-cultural associations reported by Textor (1967). Twelve factors are identified.

This book examines male and female power in various kinship configurations. Variables for male dominance and female autonomy are associated with various political and social variables, such as political complexity and co-wife jealousy. Several hypotheses are supported.

The second and third parts of this book classify the economic systems of foraging and agricultural societies in the SCCS based on correlations between their institutions of property an distribution. These economic types are then examined for relationships with other social, political, demographic, and environmental factors in order to draw tentative conclusions regarding the origins of the Agricultural and Industrial Revolutions. The fourth part of the book uses cross-national data to examine similar associations in industrial/service economies, and is not included here.

This study examines relationships among the instruction of children, household type and size, and political integration. Particular attention is paid to type of instruction--whether the instructor is kin or non-kin, and whether the instruction requires a change in the child's residence. Different types of instruction are theorized to solve problems for children in different household types (e.g. children in mother-child households experience gender identity conflict, and so leave their houses for instruction from non-kin). The causality between instruction and societal complexity is also discussed.

This book investigates a broad hypothesis linking social solidarity and initiation ceremonies. The author proposes that “the degree of solidarity of a given social system determines the degree to which status transitions within it will be dramatized” (1). A variety of operational hypotheses are supported for both male and female initiation ceremonies.

This study focuses on apology as a mechanism for dispute management in relation to hierarchy and child socialization. Significant associations exist between both large, paramount chiefdoms and apology and between adults as caretakers in early childhood and apology.
