This chapter is concerned with correlates of warlikeness among non-industrial societies. Findings indicate that warlikeness is associated with climate, mobility, subsistence, political integration, division of labor, culture contact.

Using a new measure called "territorial fractionalization" to indicate the extent to which traditional societies are split across current states, the authors of this study propose that fragmentation of ethnic groups and ethnonationalism is key to understanding civil conflict. They find that higher measures of territorial fractionalization significantly predict a higher risk of civil conflict, and that greater increases in territorial fractionalization also predict greater risk of civil conflict. These results hold for a global sample of data from 1945 to 2017, as well as in European and African subsamples dating back to 1886.

This paper tests "theories which suggest that there are causal-functional relationships between the dependent variables peacemaking and peace stability on the one hand and certain independent variables, such as political complexity, warrior class, warfare objectives, cultural homology and intersocietal ties, on the other hand." Significant relationships were found between the last three independent variables.

In previous studies, researchers have observed an increased growth rate in rats that experienced stimulation during infancy. This study examines the relationship between stressful experiences during infancy and adult male stature in humans cross-culturally. Results suggest a strong positive relationship between infant stress and adult male stature.
