Modern building codes and architectural practices don’t incorporate numerical superstitions, resulting in both odd and even-numbered staircases in contemporary construction. However, some traditional builders and architecture firms catering to culturally specific clients maintain awareness of these preferences. Research in environmental psychology suggests people do generally prefer symmetrical and balanced architectural features, providing partial scientific validation for traditional aesthetic principles. This architectural superstition demonstrates how practical design considerations regarding human movement patterns became encoded in numerical rules that gained supernatural significance in traditional building practices.
