The study of how different logical frameworks emerge from and reflect human psychology—why we invented classical logic, why we developed alternative logics, and why different cultures and contexts favor different reasoning styles. Logical systems aren't just abstract formalisms; they're tools shaped by human needs and limitations. Classical logic reflects our desire for certainty; fuzzy logic reflects our experience of gradation; paraconsistent logic reflects our tolerance for contradiction. The psychology of logical systems examines how our psychology creates logic, and how logic in turn shapes our psychology—making us think in certain ways, ruling out others, defining what counts as reasonable.
Example: "She applied the psychology of logical systems to understand cultural differences in reasoning. Western logic emphasized non-contradiction; some Eastern traditions embraced paradox. Neither was wrong; they were different tools for different purposes, shaped by different psychological needs. Understanding this didn't resolve cross-cultural debates, but it explained why they were so persistent."
