What is psychological safety choice architecture?

Psychological safety choice architecture is a concept in personal epistemology: The same principles that work for personal choice architecture work for teams.

Example: Your team adopts a new project management tool. Within a week, the tool's default notification settings have every team member receiving alerts for every comment on every task. Nobody configured this. Nobody chose it. But now every developer is interrupted an average of fourteen times per hour by notifications about tasks they are not working on. Two months later, the team's deep work output has dropped measurably, frustration is high, and someone suggests the tool 'doesn't work for us.' The tool works fine. Its default choice architecture doesn't. The team never designed its notification environment — it accepted the vendor's defaults, which were optimized for engagement metrics, not engineering output.

This concept is part of Phase 38 (Choice Architecture) in the How to Think curriculum, which builds the epistemic infrastructure for choice architecture.
