Psychological safety is the basis of any good collaboration. It is also the foundation of trust, the bottom layer of Lencioni’s pyramid. Without that layer, every other ambition – better communication, more constructive feedback, greater innovation – is built on quicksand.
At mossels from brossels, we believe that creativity is the greatest asset in collaboration. But creativity only flourishes when people feel heard, valued and connected. When minority voices are also given a platform – the guiding principle of Deep Democracy – and when team members dare to speak their minds without fear of reprisal. That is precisely where psychological safety begins.
You can’t build a strong, safe culture overnight. But there are ways to make this complex topic more manageable: by letting it experienced rather than just discussing it. Create an ‘aha’ moment, and use that as a springboard to take sustainable steps towards a safe environment within your organisation that everyone supports. In this article, you’ll find a brief explanation of what psychological safety entails, how to recognise when it’s lacking, and which workshops on trust will help your team make concrete progress.

Psychological safety is the shared feeling within a team that you can take interpersonal risks without facing negative consequences. In other words: you feel confident enough to ask questions, admit mistakes, express a differing opinion or ask for help, without fear of being ridiculed or punished.
The concept was brought to the attention of the academic world by Harvard professor Amy Edmondson, who demonstrated that psychological safety predicts teams’ learning behaviour and performance (Edmondson, 1999, Administrative Science Quarterly).
Since then, the evidence has only become stronger.
A meta-analysis of 136 studies involving more than 22,000 participants confirmed that psychological safety is associated with better team performance, greater willingness to learn, higher levels of engagement and greater job satisfaction (Frazier et al., 2017, Personnel Psychology).
A lack of psychological safety rarely shouts. It whispers. You can recognise it by:
And an important distinction: psychological safety is sometimes confused with “being nice to one another”. That is not the same thing. A psychologically safe team does, in fact, have difficult conversations, calls each other to account, gives honest feedback and sets high standards. The difference lies in the how: with respect, curiosity and a shared aim to improve together; not out of guilt, shame or fear.
Amy Edmondson’s research highlights a number of crucial building blocks:
Psychological safety in teams can be summarised in four questions:
Is the answer to all four questions “yes”? If so, there’s a good chance your team feels psychologically safe.

You can’t build trust with just one workshop. But a well-chosen trust-building workshop can create the ‘aha’ moment that marks the start of lasting change. These are our favourites.
Psychological safety begins with inner calm. In this accessible yet powerful introductory session, your team will experience, through breathing, movement and mindfulness, what it feels like to step out of ‘stress mode’. We combine Chi Kung with martial arts exercises: a wonderful illustration of how internal relaxation enables you to best navigate the ‘battlefield’ around you. An energetic approach that opens up the conversation about safety without making it feel heavy.
Play is the shortest route to real behaviour. During game-based learning Masks come off and patterns become apparent: who takes the initiative, who remains silent, how do you communicate under pressure? Through an ‘aha’ moment, your team truly realises where the friction lies — in a safe way, without anyone being singled out. Exactly what you need to make psychological safety a topic of discussion.

Are you unsure what would suit your team best?
You only feel secure in a team when you realise that your contribution matters. In this workshop, we’ll make everyone’s talents visually apparent to one another: where do your natural strengths lie, what do you bring to the table, and how do differences reinforce one another? Inclusion and belonging – one of Edmondson’s building blocks – become very tangible here. Find out how it went in the Case study: Kick-off for the leadership programme at Volvo Trucks.
Daring to ask for help is one of the clearest signs of psychological safety; and one of the most difficult. In this creative team-building workshop Your team works together to create a work of art, using an approach that makes both giving and receiving help a tangible experience. No talk of vulnerability, but vulnerability in action.
Good feedback is about behaviour, not the person. It is specific and intended to help people develop. In the workshop connecting communication teaches your team to give feedback based on curiosity rather than judgement. The difference between “Why did you do that?” and “What made you choose this?” — small in words, big in impact.


Based on Lencioni’s model, in which trust forms the bottom layer of the pyramid. With a Baseline survey on the five frustrations in collaboration It helps your team assess where it stands today: do we dare to disagree, or are we perpetuating an illusion of harmony? An ideal starting point for teams that don’t want to take any chances, but want to work purposefully on psychological safety.
Sometimes trust isn’t something to be discussed, but something to be experienced. During this outdoor team-building Your team can only succeed by really relying on one another. The reflection afterwards helps us apply this to the workplace: when did trust develop, and what do we recognise from our day-to-day collaboration?
Remember: psychological safety isn’t created by a single workshop. It grows when people experience, time and again, that agreements are honoured, mistakes aren’t held against them, and difficult conversations are conducted respectfully. A trust workshop is the ‘aha’ moment; day-to-day practice is where the real work happens. That’s why every session we run ends with concrete actions your team can put into practice the very next day; and we’re happy to help you plan the follow-up.
