Psychological Safety

Noun · Hacker Culture

Definitions

  1. A team environment where members feel safe to take interpersonal risks — admitting mistakes, asking 'dumb' questions, proposing unconventional ideas, and giving honest feedback without fear of punishment or embarrassment. Google's Project Aristotle found it was the #1 predictor of high-performing teams. Essential for blameless postmortems and learning cultures.

    In plain English: A team culture where people feel safe to admit mistakes and ask questions without fear of being judged or punished.

    Example: "In a psychologically safe team, a junior dev can say 'I don't understand this architecture' without being judged — and the team gets better documentation as a result."
