Shame has biological roots, possibly enhancing trust, favoring social cohesion. We studied bioeconomic aspects of shame and guilt using three approaches: 1—Anthropo-linguistic studies of Guilt and Shame among the Yanomami, a culturally isolated traditional tribal society; 2—Estimates of the importance different languages assign to the concepts Shame, Guilt, Pain, Embarrassment, Fear and Trust, counting the number of synonyms listed by Google Translate; 3—Quantitative correlations between this linguistic data with socioeconomic indexes. Results showed that Yanomami is unique in having overlapping synonyms for Shame, Fear and Embarrassment. No language had overlapping synonyms for Shame andGuilt. Societies previously described as “Guilt Societies” have more synonyms for Guilt than for Shame. A large majority of languages, including those from societies previously described as “Shame Societies”, have more words for Shame than for Guilt. The number of synonyms for Guilt and Shame strongly correlated with estimates of corruption, ease of doing business and governance, but not with levels of interpersonal trust. We propose that cultural evolution of shame has continued the work of biological evolution, but its adaptive advantageto society is still unclear. Results suggest that recent cultural evolution must be responsible for the relationship between the levels of corruption of a society and the number of synonyms for Guilt and Shame in its language. This opens a novel window for the study of complex interactions between biological and cultural evolution of cognition and emotions, which might help broaden our insight into bioeconomics. © 2014, Springer Science+Business Media New York.
