意味

Psychological safety — the belief that you can speak up, make mistakes, and share ideas without fear of punishment or humiliation at work.

Popularized by Google's Project Aristotle findings, 心理的安全性 became one of Japan's biggest workplace buzzwords in the 2020s. It resonated deeply because Japanese workplaces often suffer from rigid hierarchies, fear of speaking up (空気を読む culture), and punishment for mistakes. Companies now cite it in management training, though critics note the gap between using the term and actually creating safe environments.

1. 心理的安全性がない職場だと、誰も意見を言わなくなるんだよね。

3. 心理的安全性って最近よく聞くけど、実践できてる会社は少ないと思う。
