Psychological Safety as a Technical Property of Engineering Teams

Short summary

Psychological safety is a technical property of engineering teams, not an HR buzzword — it determines code quality, recovery speed, and tech debt accumulation. Low-safety cultures produce silent outages, unpaid tech debt, and adversarial code reviews because engineers fear blame. Leaders can design safety by modeling vulnerability, reframing feedback to target code not people, and running blameless postmortems.
