To warm up, let’s consider four aspects of WEIRD psychology that likely had broad influences on the formal institutions built in Europe during the second millennium of the Common Era.
- Analytic thinking: To better navigate a world of individuals without dense social interconnections, people increasingly thought about the world more analytically and less holistically/relationally. More analytically oriented thinkers prefer to explain things by assigning individuals, cases, situations, or objects to discrete categories, often associated with specific properties, rather than by focusing on the relationships between individuals, cases, etc. The behavior of individuals or objects can then be analytically explained by their properties or category memberships (e.g., “it’s an electron”; “he’s an extrovert”). Troubled by contradictions, the more analytically minded seek out higher- or lower-level categories or distinctions to “resolve” them. By contrast, holistically oriented thinkers either don’t see contradictions or embrace them. In Europe, analytical approaches gradually came to be thought of as superior to more holistic approaches. That is, they became normatively correct and highly valued.
- Internal attributions: As the key substrates of social life shifted from relationships to individuals, thinkers increasingly highlighted the relevance of individuals’ internal attributes. This included stable traits like dispositions, preferences, and personalities as well as mental states like beliefs and intentions. Soon lawyers and theologians even began to imagine that individuals had “rights.”
- Independence and nonconformity: Spurred by incentives to cultivate their own uniqueness, people’s reverence for venerable traditions, ancient wisdom, and wise elders ebbed away. For good evolutionary reasons, humans everywhere tend to conform to peers, defer to their seniors, and follow enduring traditions; but, the incentives of a society with weak kin ties and impersonal markets pushed hard against this, favoring individualism, independence, and nonconformity, not to mention overconfidence and self- promotion.
- Impersonal prosociality: As life was increasingly governed by impersonal norms for dealing with nonrelations or strangers, people came to prefer impartial rules and impersonal laws that applied to those in their groups or communities (their cities, guilds, monasteries, etc.) independent of social relationships, tribal identity, or social class. Of course, we shouldn’t confuse these inchoate inklings with the full-blown liberal principles of rights, equality, or impartiality in the modern world.
