Trust is a price, not a poster
Psychological safety is not niceness. It's the observed cost of telling the truth, and you set that price with your own reactions.

Psychological safety got popular and then got soft, and the soft version is worse than useless because it makes the real thing sound optional.
The real thing is not a feeling and it isn't about being nice. It's a price. Everyone in your organisation is carrying an estimate, updated constantly, of what it costs to say a true and unwelcome thing out loud. That estimate governs how much of what's actually happening reaches you.
You set the price. Not with a values statement. With about four seconds of your own face.
The three moments where it's actually priced
The price gets set in specific moments, not in the general atmosphere, and almost all of them are ones you barely register at the time.
The first is when someone brings you bad news early. Early bad news is always incomplete and usually a bit wrong, because it's early. The engineer who says "I think the migration might be in trouble" does not have a full picture, and the natural response is to ask a few sharp questions that they can't answer yet. That exchange, which feels to you like diligence, teaches them that the cost of speaking early is looking unprepared in front of you. Next time they'll wait until they have answers, and by then it won't be early.
The second is when someone disagrees with you in a room with other people in it. Not in private. In front of an audience, where your reaction is being watched by everyone deciding whether they'd risk the same thing. If the disagreement costs them anything visible, even a flicker, you've just set a price for the entire room, and it's much higher than the one you thought you were setting for one person.
The third is when something fails and the org watches what happens to the people involved. This is the loudest signal you will ever send about safety, and it's sent by what you do, over the following week, to people who did something that didn't work.
Everything else, the offsites, the phrasing, the surveys, is downstream of those three.
Reward the messenger, visibly, on the spot
My rule on bad news is simple and slightly uncomfortable to execute: thank the person in front of other people, immediately, before doing anything about the problem itself.
Not in a one-to-one afterwards. Not in a note. In the room, out loud, at the moment it lands. "Good. I'm glad you said that now rather than in three weeks." Then deal with the substance.
It's uncomfortable because the substance is usually urgent and your instinct is to move straight to it. Skip the acknowledgement and the message the room receives is that bad news is an interruption, correctly handled by a competent adult, and no more. Which is fine, and produces an organisation that tells you things exactly on time, meaning too late.
The visibility is doing most of the work here. One person hearing that you appreciated the warning changes one person's behaviour. Six people watching you appreciate it changes six, and it's the cheapest thing you'll ever do with your own reactions.
The corollary is that you don't get to also be visibly annoyed at the news. You can be annoyed. Just not in that moment, not in that room, and not at that person. Whatever frustration you're carrying about the situation is now something you're paying for privately, and that's the actual job.
What quietly raises the price
A short list of things that don't look like anything and cost you enormously.
Asking "why didn't we know about this sooner" in a group setting. It sounds like a process question and it lands as an accusation, and everyone in the room hears that the answer to a surprise is an investigation into who was slow.
Solving the problem yourself the moment you hear about it. Feels like support. Reads as "you weren't handling this."
Going quiet. A leader who receives bad news with a long silence and a neutral face is read as furious, every single time, by everyone. Neutrality is not a safe default, it's an ambiguous one, and people resolve ambiguity pessimistically about their own standing.
Having a favourite. If disagreeing with one particular person is expensive, the whole org learns to route around that person, and you'll be the last to find out because the routing happens in private conversations you're not in.
Repair, when you got it wrong in public
You will get one of these wrong. Everyone does, usually on a day when three other things were already going badly.
Repair is cheap and most leaders don't do it, because it feels like it will undermine authority. It does the opposite, but the sequencing matters.
Name the specific thing, not the general failing. "I cut you off in the review yesterday and then made the decision without hearing the rest of it" beats "I've been a bit short with people lately." Vague apologies are read as PR.
Do it where the original happened. If it was in front of eight people, the repair goes in front of the same eight, because the price you set was set for all of them.
Then say what will be different, once, briefly, and stop talking about it. An apology that keeps going becomes a thing the other person has to manage for you, and now they're doing emotional labour as a consequence of your mistake.
And don't do it too often. Repair works because it's rare and costly. A leader who apologises weekly has just made apology part of the ambient noise.
Safety is not a lower bar
The most common objection to all of this is that it produces a soft organisation where nothing is expected of anyone. That objection is worth taking seriously, because there genuinely are organisations like that, and they're miserable to work in for exactly the people you most want to keep.
The distinction: safety is about what happens when you tell the truth. It is not about what happens when you don't do the work.
You can run a hard bar and a safe org at the same time, and the best ones do. What that looks like in practice is that the standard is explicit and the same for everyone, feedback on the standard arrives quickly and unsentimentally, and being behind the standard is a solvable, discussable state rather than a secret.
The two go together more than they trade off. A soft organisation is usually one where nobody will say the true thing about someone's performance either, and that's the same failure pointed at a person instead of at a project.
The tell
You don't measure this with a survey. You measure it with timing.
When you find out about a problem, ask how long the person who told you had known. If the answer is consistently "a few days," you're fine. If it's consistently "a few weeks, and a couple of us had talked about it," you have your number, and no amount of restating the values will move it.
Only your reactions will.
