Most legal departments operate at the first stage of psychological safety and stop there. The other three stages are where the work actually gets better.
In December 2025 I spent a morning with the Legal Services Department of the Kenya Revenue Authority, by invitation from the Law Society of Kenya. The brief was practical: a session on the Four Stages of Psychological Safety, applied to the realities of practising law inside a major public institution. The conversation that followed was the kind I have now had dozens of times in legal environments - and the patterns repeat with a frequency that should make the profession uncomfortable.
What "psychological safety" actually means
Psychological safety is not the absence of disagreement. It is not soft, and it is not the same as comfort. Drawing on the work of Amy Edmondson and Timothy R. Clark, psychological safety is a belief - held inside a team - that one can speak up, take interpersonal risks, and engage honestly without paying a disproportionate personal cost. In Clark's framework it operates in four progressive stages, each unlocking the one above it.
Stage one - inclusion safety
This is the floor. People feel included as human beings. They are recognised, addressed by name, not made to feel like outsiders on the basis of their identity, background, or seniority. Most reasonably-managed legal teams clear this bar. Many do not - and the ones that do not usually believe that they have, which is its own problem.
What inclusion safety looks like in practice: new joiners are introduced properly. Quiet team members are drawn into discussion rather than allowed to disappear. Identity-based remarks are not tolerated, regardless of who they come from. Meetings start and end on time, and the seniors-speak-first norm is examined honestly.
Stage two - learner safety
People feel able to learn. They can ask questions, admit they do not know something, make mistakes, and ask for help - without those acts being held against them. This is where many legal environments stall. The profession trains a kind of confident omniscience that makes "I do not know" feel like a professional admission of weakness rather than what it is: a precondition for learning anything new.
The cost of low learner safety is hidden but enormous. Junior lawyers do not raise concerns about unfamiliar areas. Senior lawyers do not update their thinking. The team's collective competence ossifies in place. The fix is structural - supervision frameworks that reward genuine inquiry, debriefs that focus on what was learned rather than who was right, leaders who model not knowing in front of their teams.
Stage three - contributor safety
People feel able to contribute. They can do the work, use their judgement, and exercise discretion - at a level appropriate to their role - without being micromanaged into uselessness or hung out to dry when something goes wrong. The two failure modes here are equally common in legal environments: smothering oversight that prevents people from developing, and absent oversight that exposes them to risk they cannot manage alone.
Contributor safety is what turns capable individuals into a capable team. It requires that the seniors trust the juniors with real work and that the juniors trust the seniors to have their backs when the work is hard. Where it is missing, you can see it in the timesheets and the turnover register.
Stage four - challenger safety
This is the stage almost no legal team reaches. People feel able to challenge the status quo - to disagree with a senior, to raise a difficult ethical question, to flag a strategy that is heading in the wrong direction - without paying a personal price for the challenge. Challenger safety is the precondition for an organisation to learn from its own mistakes, to course-correct under pressure, and to operate with integrity when the stakes are high.
It is also, predictably, the stage where the cost of getting it wrong is most visible. Boards that lack challenger safety produce groupthink and miss obvious risks. Legal departments that lack it produce work that is technically competent and strategically blind. The signal that a team has reached this stage is simple: junior people disagree with senior people, in meetings, on the record, and the senior people thank them for it.
Why this matters for legal teams specifically
Three reasons. First, legal work is high-consequence work. The cost of a missed argument, an unflagged conflict of interest, or an unspoken ethical concern can be measured in financial penalties, professional sanctions, or human harm. A team operating at the first stage of psychological safety produces these costs as a matter of course.
Second, the profession has a documented mental-health crisis. Burnout, substance use, and depression are present in legal populations at rates significantly higher than in matched professional populations. The structural conditions that produce those outcomes are the same ones that suppress psychological safety - long hours, hierarchical pressure, a culture that treats vulnerability as weakness, and a relationship to mistakes that punishes rather than learns.
Third, the profession is changing. The next generation of lawyers is choosing differently. Teams that cannot offer the conditions for genuine professional engagement will lose talent to teams that can. This is not a soft observation about generational difference - it is a recruitment and retention problem with measurable financial consequences.
The moves that get you to the next stage
The work is not about declarations. Posting a statement about psychological safety does nothing - and may actively reduce trust, because it signals that the leadership cares about the appearance of the thing rather than the practice. The work is about specific behavioural moves, repeated by leaders, until they become the team's default.
To raise inclusion safety: name people, invite them in, push back consistently on exclusionary behaviour from anyone, regardless of seniority. To raise learner safety: model "I do not know" out loud, restructure debriefs around learning rather than blame, separate performance from the willingness to engage. To raise contributor safety: delegate the work, give the support, take the heat when things go wrong, share the credit when they go right. To raise challenger safety: thank people, publicly, for disagreeing with you - and act on it when they are right.
What I told the KRA team
The closing point of the December session, more or less verbatim: a legal team that operates at stage four is not a softer team. It is a sharper one. It catches its own mistakes. It produces better legal work. It retains its people. And - for an institution operating in the public interest - it does the public a more honest service than a team that has confused silence for competence.
The four stages are not aspirational. They are a diagnostic. Every legal team in the country can be located on them, today, with reasonable accuracy. The interesting question is not where the team is. It is where the leadership is willing to take it.
