The psychological safety diagnostic: eight questions to ask your team
Psychological safety is usually discussed in the abstract and almost never measured. These eight questions are designed to be asked of a real team, and each one comes with what a poor answer is actually telling you and the smallest change that shifts it.
45% of UK employees do not feel able to raise mistakes or risks at work, and 15% say stress and fear are causing them to make more mistakes. Silence is not a wellbeing issue with a performance side effect. It is an operational risk. MHFA England, My Whole Self research, 2,000 UK working adults, published February 2026

The rest of the guide covers what psychological safety is and is not, then all eight diagnostic questions: what to ask, what a poor answer means and the smallest change that moves it. One-off, you won’t need to do this again on this device.
What psychological safety is, and what it is not
The term has been in circulation long enough to be widely misused. Getting it right matters, because the most common misreading leads leaders to do the opposite of what helps.
It is not about being nice
The concept, developed and popularised in the organisational research of Amy Edmondson at Harvard Business School, describes a shared belief that the team is safe for interpersonal risk-taking. Not that it is comfortable. That speaking up will not be punished. A psychologically safe team can be blunt, can disagree hard and can tell a senior person they are wrong. A conflict-avoidant team that has confused politeness with safety is often the least safe of all, because nothing difficult ever gets said out loud.
It is not the absence of standards
The second misreading treats safety as leniency, as though holding a high bar and making it safe to speak up were in tension. They are not. High standards without safety produce anxiety and concealment. Safety without standards produces comfortable underperformance. The combination worth aiming for is a team that is expected to do excellent work and is entirely safe to say when something is going wrong.
Leaders routinely read silence in a meeting as agreement. It is more often a team that has learned that speaking up costs something. The absence of bad news is not the presence of good news, and it is usually the cheapest early warning an organisation ever declines to collect.
Eight questions, and what the answers mean
Ask these of your team, ideally anonymously and definitely not in a room where you are watching people answer. What follows each question is what a poor answer is telling you, and the smallest change that moves it.
“If I made a mistake on this team, would it be held against me?”
The foundational one, and the one the UK data says is failing badly: 45% of employees do not feel able to raise mistakes or risks at work. A poor answer here tells you that errors are being concealed rather than fixed, which means the first time you hear about a problem is the point at which it has become expensive.
- Name one of your own mistakes out loud, with what you learned. Nothing moves this faster and nothing is harder to fake.
“Can I raise a problem or a tough issue here?”
Distinct from question one, because this is about problems that are nobody’s fault: a plan that will not work, a deadline that is not real, a client relationship going wrong. A poor answer means your escalation route is decorative and bad news is travelling sideways among peers rather than upwards to you.
- Thank the person who brings you the problem, visibly, in front of others, before you start solving it.
“Is it safe to disagree with the most senior person in the room?”
This is the load-bearing one for decision quality. If the answer is no, every meeting you chair is producing consensus that is not real, and you are the last person who will find out. The symptom is a meeting that ends with agreement and a corridor conversation that contradicts it.
- Speak last, not first. A leader’s opening view sets an anchor that most people will not move away from.
“Am I comfortable saying what I need to do my job well?”
Nearly half of UK employees are not: 49% do not feel comfortable expressing their needs at work. A poor answer means people are quietly absorbing friction you could remove for almost nothing, and it is the question that most often surfaces the cheap fixes nobody had mentioned.
- Ask the whole team what would make their work easier, and then visibly do one of the things.
“Can I ask for help without it counting against me?”
35% of UK employees do not feel safe asking for help. Where that is true, people struggle privately for longer than they need to, work takes longer than it should and the first visible sign is a missed deadline that had weeks of warning nobody was allowed to give.
- Ask for help yourself, in public, on something real. Permission is granted by example far more than by policy.
“When something goes wrong here, do we ask what happened or who did it?”
The answer to this determines every other answer on the list. A team that reliably looks for the cause will surface problems early. A team that looks for the responsible individual will surface them at the point of failure, because until then everybody is managing their own exposure rather than the risk.
- Run the review before you know who was involved, and keep the first 10 minutes strictly on sequence of events.
“Do the quietest people on this team ever get heard?”
Safety is rarely evenly distributed. It is usually high for the confident, the long-tenured and the people most like the leader, and low for everybody else. An organisation-wide average will hide this completely, which is why the question has to be asked at team level and read by who is answering it.
- Circulate the question before the meeting and invite written input. It changes who contributes more than any facilitation technique.
“What happened the last time someone here spoke up?”
The most revealing question of the eight, because it asks for evidence rather than a feeling. Everyone on a team knows the answer and almost nobody has been asked. One badly handled example, two years old, will still be governing behaviour today, and it will not appear in any survey.
- If there is a story like that, name it and address it. Pretending it did not happen is why it is still working.
Psychological safety is created and destroyed at team level, by the behaviour of one leader. An organisation-wide score is the average of some excellent teams and some poor ones, and it will tell you almost nothing about either. Two teams that give you the same summary answer can be entirely different places to work.
Build leaders people will tell the truth to
Psychological safety is a leadership output, not an HR programme. Our Leadership Development Training works on the behaviours that create it: how you respond to bad news, how you run a decision and how you make it safe to disagree with you. Onsite or online, cohort or one to one, tailored before delivery.
