The neuroscience behind relationships that help us grow
What if one of the most powerful tools for changing a person’s life isn’t a programme, a qualification, a performance review or even a brilliant piece of advice? What if it is another human being?
We often talk about mentoring as though it is something we do for someone else—providing guidance, sharing experiences, offering encouragement, and asking questions. However, emerging neuroscience suggests that we need to think about mentoring differently.
A good mentoring relationship doesn’t just influence what we think. It influences the environment in which our brain thinks, which changes everything.
Your brain is a social organ
For many years, neuroscience focused heavily on the individual brain: memory, attention, decision-making, emotion and learning.
Increasingly, researchers are examining what happens when the brain operates in relationship with other people.
A 2025 review in Nature Reviews Psychology noted that social connection is not one simple phenomenon. Researchers now distinguish between several dimensions, including our subjective sense of connection, our social networks, interpersonal synchrony, and the behaviours through which we connect with others.
Other neuroscience research has identified neural systems involved in social reward, social cognition, and stress buffering. Positive social interactions can help reinforce connection, and may help people cope with stress and isolation.
In other words, relationships aren’t simply something happening around the brain; they are part of the environment in which the brain operates, which is why mentoring can matter so much.
Before the brain can grow, it needs to feel safe
Think about the last time someone criticised you unexpectedly. How did you react?
Perhaps your first reaction was defensiveness, not curiosity; maybe you wanted to justify yourself, or perhaps your thinking became narrower rather than clearer.
Now think about a very different experience, when someone you trust says: “Tell me what happened.”
They listen, don’t rush to judge, remain calm, and ask a thoughtful question. Suddenly, you can think again.
This is at the heart of what your brain is constantly doing: assessing the social environment.
Research on social safety describes the brain as continually evaluating whether the social world around us is safe or threatening. Social threat can engage systems associated with stress and defensive responses, while supportive social relationships can help buffer the effects of stress, which gives us a powerful insight into mentoring.
Connection comes before influence, the principle that sits at the beginning of the Mentoring Matters Framework. People grow best where they feel safe, seen, valued and encouraged.
A mentor can change the emotional climate
One of the most important qualities of a mentor may therefore be something surprisingly effortless: calmness. When someone is anxious, overwhelmed or uncertain, another person’s emotional steadiness can help change the atmosphere of the interaction.
This doesn’t mean that a mentor magically removes stress, rather that the person no longer has to navigate the situation entirely alone.
Recent research provides an intriguing example. In a 2025 fMRI study, researchers found that social support reduced threat responses and helped participants retain the extinction of threat memories. The study involved 96 participants, with brain imaging showing differences in activity and connectivity associated with social support.
We should not overinterpret one study, as it doesn’t prove that every mentoring conversation changes someone’s brain. However, it does add to a growing body of evidence suggesting that supportive relationships can influence how the brain processes stress and threat, which has enormous implications for mentoring.
Listening isn’t just polite
One of the most underestimated mentoring skills is listening, which many people often think is a courtesy. “I’m listening to you because I respect you.”
Deep listening may do something more profound, for it creates space for another person to organise their own thinking.
When we talk through a difficult situation with someone who listens carefully rather than immediately giving advice, something interesting often happens—we hear ourselves think, we make connections, identify possibilities, and discover what we actually believe.
That is why one of the stories in one of my books describes a young man who asked his mentor what he should do. Instead of giving him an answer, the mentor asked: “What do you think you should do?” The young man eventually discovered that he already carried the beginnings of his own answer. He just needed someone to listen.
That is creating the conditions for thinking, and not passive mentoring.
The brain is built to learn socially
Another fascinating development in neuroscience is our growing understanding of social and emotional learning.
A 2024 review in Nature Reviews Neuroscience examined the role of the posterior cerebellum in social and emotional learning, describing networks involved in observing actions, understanding other people’s mental and emotional states, and processing emotional experiences.
This matters because mentors don’t tell people what to do. They model, demonstrate, respond, ask, and listen. They also regulate their own emotions, show what curiosity, courage, and humility look like. In other words, mentoring is partly learning through relationship and observation, which is why Model Behaviour is one of the foundations of the Mentoring Matters Framework’s Character dimension.
People learn from what we repeatedly show them, as well as from what we tell them.
There is hope
Perhaps the most powerful thing a mentor can offer is not an answer to today’s problem, but a larger view of tomorrow.
When someone is discouraged, their perception of the future can become extremely narrow:
“I’ll never get this right.”
“I’m not good enough.”
“Nothing is going to change.”
A mentor can attempt to positively and empathetically interrupt that narrative.
“I can see something in you that you can’t see yet.”
“This setback doesn’t define your future.”
“Let’s think about what might be possible.”
That is why the final foundation of my framework is Calling.
Mentoring is helping someone recognise strengths, develop ownership and discover hope and possibility, and not just about helping them cope with the present.
Mentoring works in both directions
An important point sometimes missed during the mentoring journey is that mentoring isn’t something an experienced person does for an inexperienced person. It can be profoundly reciprocal.
A mentor listens and learns; a manager learns from a younger employee; a grandparent learns from a grandchild; a teacher learns from a student, and an experienced professional discovers a new perspective through someone just beginning their career.
Research has even found benefits associated with being a mentor, including higher job satisfaction and organisational commitment, although researchers caution that much of the evidence remains correlational and more longitudinal research is needed.
So perhaps the better question isn’t: “Who needs a mentor?”, but, “Who do I need to be in relationship with if I want both of us to keep growing?”
The quality of the relationship matters
One of the most important findings for leaders is that simply assigning someone a mentor doesn’t guarantee transformation. The relationship matters.
A 2025 workplace study of 268 employees found that mentorship quality fully mediated the relationship between mentoring functions and outcomes including self-esteem and employee wellbeing, a finding that fits extremely well with what I have observed across decades of mentoring.
The label matters less than the relationship; the programme matters less than the person, and the meeting matters less than what happens between the people in the room.
Expertise, on its own, isn’t enough. You can be highly experienced and still be a poor mentor; have enormous knowledge and still fail to connect, can give excellent advice and still have very little influence, because people don’t open their minds simply because we have something valuable to say. They open when they trust the person saying it.
What the brain-smart mentor does
There are a few well-researched straightforward effective practices:
Be present.
Give someone your undivided attention.
Listen deeply.
Don’t rush to fill every silence with advice.
Create safety.
Make it possible to admit uncertainty and mistakes without humiliation.
Stay calm.
Become a steady presence when someone else’s world feels unsettled.
Show curiosity.
Ask questions that help people think, rather than questions designed to demonstrate how much you know.
Model behaviour.
Let people see the character you hope they will develop.
Affirm strengths.
Help people notice capabilities they may not yet recognise in themselves.
Encourage ownership.
Don’t solve every problem. Help people develop the capacity to solve problems themselves.
Inspire hope.
Help someone see possibilities beyond their present circumstances.
These are relational habits, not complicated techniques, and they are similar to the twelve principles in the Mentoring Matters Framework.
Perhaps the brain doesn’t need more information
We live in an extraordinary age of information, where we can access almost anything, ask artificial intelligence for an answer in seconds, watch a tutorial on almost any subject, and learn from experts anywhere in the world.
However, none of this eliminates our need for human connection. Information can tell us what to do, while a positive relationship can help us believe that we are capable of doing it. Information can provide knowledge, and a mentor can provide that all important perspective. Information can offer answers, but a mentor can help us discover our own.
And information can be everywhere while a person can still feel completely alone, which is why mentoring matters so much.
The human brain is not designed to flourish in isolation.
The human brain grows, learns, adapts. and makes meaning in relationship with others. So, the next time you have an opportunity to mentor someone, don’t underestimate what is happening.
You may think you’re simply having a conversation, but you may actually be helping create the conditions in which another person can think more clearly, feel more secure, imagine more hopefully and grow more confidently—that is the real power of mentoring, creating a relationship in which they become increasingly able to discover who they can become, and not changing someone by telling them what to do.
A question to consider
Who is one person in your life who might benefit from a little more of your presence, curiosity, encouragement or belief this week?
You may never know how much that relationship matters, but then, that has always been the quiet power of mentoring.
One relationship can change a life.
Because Every Life Matters.
