The Surprising Link Between Biscuits and Psychological Safety

There could be members of your team who stay quiet in a meeting when they have a brilliant idea, or worse, a genuine concern. Chances are, it will be confidence they lacked or psychological safety.

 

Coined by Harvard researcher Amy Edmondson, psychological safety describes a team climate where people feel safe to speak up, admit mistakes, ask questions, and challenge the status quo without fear of humiliation or punishment.

Google's famous Project Aristotle study found that psychological safety was the single biggest predictor of high-performing teams, beating out talent, resources, or even leadership style.

 

 

The tricky part is that psychological safety isn't built through policy documents or one-off workshops. It's built through hundreds of small, repeated signals:

- how a manager reacts to a mistake, 

- whether junior voices get airtime, 

- whether vulnerability is met with warmth or awkward silence. 

It's cultural muscle memory, and like any muscle, it needs regular, consistent exercise.

This is where small gestures matter more than grand ones. A single team lunch won't fix a toxic culture, but consistent, low-stakes moments of care can rewire how safe people feel to be themselves at work.

 

 

Here's the connection that might surprise you: sharing food, especially something as unpretentious as a biscuit, is a proven social lubricant. Research on commensality (the practice of eating together) shows that shared snacks and meals lower social barriers, increase trust, and open up conversation in ways that formal meetings rarely do.

 

Biscuits that speak to the occasion do a few quietly powerful things:

 

None of this replaces the harder work of building trust, leaders modelling vulnerability, teams normalising failure, feedback being genuinely welcomed. But it lowers the emotional temperature enough for that harder work to actually happen.

 

 

We built The Biskery around a simple belief: gratitude compounds. Every Tuesday, we gift free biscuits to someone who needs a lift, and our customers help make that happen by sending biscuits to people they appreciate. It's a small ritual, but rituals are exactly what psychological safety runs on: predictable, low-cost signals that say "you're seen here."

 

If you're a people leader wondering where to start, you don't need a culture overhaul. Start smaller. Send your message on a biscuit to a team that just navigated a tough project. Personalise a box for someone who took a risk, and it didn't pan out. Make appreciation visible, edible, and frequent.

 

Because sometimes the fastest way into someone's guard isn't a performance review or a trust exercise. It's a biscuit, and the five minutes of shared silence while everyone decides which one to take first.
