Psychological traits developed from "summary" of The WEIRDest People in the World by Joseph Henrich
Psychological traits developed in response to the unique cultural environment that prevailed during the Middle Ages. In this period, the Catholic Church held significant power and influence, shaping the minds and behaviors of individuals in ways that were distinct from other societies. Through the imposition of a strict monogamous marriage system and the prohibition of cousin marriage, the Church effectively altered the social norms and practices of the Western European population. These changes had far-reaching consequences, as they impacted the way individuals thought, felt, and interacted with one another.
The psychological traits that emerged as a result of these cultural shifts were not arbitrary or random but were shaped by the specific demands and constraints of the medieval environment. For example, the emphasis on individualism and personal autonomy can be traced back to the Church's teachings on sin, guilt, and redemption. The idea that each person is responsible for their own actions and must seek salvation through personal repentance and faith laid the foundation for a culture that values self-reliance and self-expression.
Furthermore, the emphasis on fairness, equality, and justice in Western societies can be attributed to the Church's promotion of moral values and ethical principles. The belief in the inherent dignity and worth of every individual, regardless of social status or background, fostered a sense of empathy, compassion, and solidarity among members of the community. These values became ingrained in the cultural fabric of Western societies, shaping their social institutions, legal systems, and moral codes.
In contrast, other societies that did not experience the same cultural influences during the Middle Ages developed different psychological traits. For example, in societies where cousin marriage was common and accepted, individuals may exhibit stronger ties to their extended family and kinship group, leading to a greater emphasis on loyalty, reciprocity, and group cohesion. These differences in psychological traits reflect the diverse ways in which culture can shape the human mind and behavior, highlighting the importance of understanding the cultural origins of our psychological traits.
