Unlock Innovation - Talk to a Stranger

Why talking to strangers is good for innovative thinking
Introduction
Going down to London a couple of weeks ago I was looking forward to putting on a good podcast and ignoring everything and everyone around me. That is until a woman, Melanie, came and plonked down next to me, with her pile of papers and her phone ringing.
Once she had taken the call, she smiled at me, I smiled back and this led to a 2 and half hour conversation on all things from professional development to managing long distant relationships.
I got off the train more energised, connected and ready for the day than if I had stuck my headphones in.
We arranged to meet for a coffee back in Liverpool.
Why am I telling you this?
Because in business, we often talk about the importance of networks and collaboration—but what if some of the most transformative insights come not from your inner circle, but from a stranger on a train, a chance encounter at a conference, or a casual conversation over coffee?
The Research
A recent UK study from the University of Essex (Sandstrom et al., 2022) showed that small talk with strangers can significantly improve mood, empathy, and creativity. More importantly, these fleeting interactions often lead to the sharing of ideas that would otherwise remain siloed. In a time when innovation and agility are everything, this matters.
Another UK study by Nesta (2019) on innovation diffusion found that ideas spread faster in communities where “weak ties” are strong—those acquaintances and peripheral connections that sit just outside our usual networks. They introduce novelty and challenge groupthink, something every CEO navigating complexity should pay attention to.
The Leadership Lens
When I work with CEOs, those in peer networks always value that outside in perspective, a fresh set of eyes. When I interviewed Tom Morgan for The Unlikely Executive Podcast he highlighted the power of talking to absolute strangers. His stranger was on the side of a soccer pitch. Showing that real breakthroughs can happen when you put down your guard and just share what your thoughts and ideas are.
The 5 Voices framework reminds us that each person has a unique voice—and when we only surround ourselves with people who speak “like us,” we lose access to vital perspectives.
When leaders only stay within their trusted circle, something important is lost. You may protect consistency and control (a strength of the Guardian), but you risk missing the unexpected insight that could change everything. Often, it’s the Creative or Connector in the room who first sees the value in an offhand comment or a half-formed idea. These seemingly small conversations—ones we often don’t prioritise—are where innovation is born.”
The Call
So here’s an invitation: be deliberate about bumping into brilliance. Attend a meet-up that’s outside your industry. Talk to a stranger, say hello as a starter! This method was used by Mel Robbins to great effect when she moved home and is outlined in her brilliant book Let Them.
Most of all, create cultures where your team talks beyond their silos too. You might be surprised by where the next big idea comes from—and who it comes from.

The Intergenerational Advantage: Why Construction Firms Who Blend Ages Will Outperform Everyone Else
If you’re worried about not having enough young people, including women coming into construction, you’re asking the wrong question. The real risk is what happens when you don’t use the people you already have properly. The Crisis No One Is Solving Properly Across the UK, the construction workforce is ageing faster than it’s being replenished. There are 20% more workers aged 55+ than under 25. And it gets worse: 35% of the workforce is now over 50, and only 20% is under 30. Yes this presents an industry risk, but closer to home we see organisational risk. Leaders worry about recruitment, apprenticeships, T levels, Skills Bootcamps all useful, but none of them address the real issue: Experience is walking out of the door every single day, and new capability isn’t being integrated fast enough. This is exactly what my conversation with Colin McEllin MCIOB of Clan Contracting highlighted. When a 21 year old commercial graduate joined Clan Contracting, Colin didn’t roll his eyes or think, “another kid who’s never been on a site.” He leaned into it and welcomes thoughts, ideas and advice from 'young Aaron'. Massive benefits for him, and Aaron, and the wider team. Why Intergenerational Leadership Is Now a Strategic Priority The construction sector is staring at a workforce cliff edge: • 140,000+ vacancies lie unfilled. • By 2036, 750,000 skilled workers will retire, stripping the industry of vital capability. • The UK will need nearly 1 million additional construction workers by 2032. Yet recruitment alone isn’t enough. You cannot hire your way out of this crisis. We must integrate generations on purpose, not by accident. What Younger Workers Bring (That Leaders Ignore at Their Peril) Younger talent offers: • Modern thinking around sustainability and digital tooling • Analytical approaches and better documentation habits • A willingness to question processes that haven't been updated since the 90s • A commercial lens shaped by newer training systems In Colin’s words, their thinking “took him right back to when he was 21” eager, energetic, ideas driven. You want that energy before they lose it. What Older Workers Bring (That You Can’t Replace) Your experienced people have: • 30+ years of instinct • Pattern recognition that no textbook teaches • Quiet influence that stabilises teams • Technical fluency on heritage, concrete, structure, sequencing, conservation, problem solving These people are your institutional memory. Once they go, they’re gone. And currently, UK engineering employers admit they only retain knowledge effectively from 57% of retiring staff. That is a crisis hiding in plain sight. Leadership Actions That Works 1. Create deliberate two way mentoring (not hierarchical mentoring). Younger staff teach digital skills, new processes, sustainability thinking. Older staff teach technical judgment, site sense, risk spotting. Both feel valued. 2. Give young people actual responsibility, not token tasks. The CITB plans 40,000+ industry placements a year. It means nothing if leaders hide young people in the corner. Let them make decisions, with support. 3. Systemise knowledge transfer. You cannot afford to rely on “ask Dave if you need help.” You need processes, templates, technical walkthroughs, shared documentation. 4. Remove the “that’s not how we do it here” reflex. 76% of construction workers say current training doesn’t adequately prepare people for the job. So your way probably isn’t the best way anymore. Your Competitive Advantage Is Sitting Right Under Your Nose When generations work in isolation, capability leaks. When generations work together, capability compounds. The firms who win over the next decade won’t be the ones who grab the talent, it will be the ones who blend talent. Listen to the full episode of the podcast here or watch on You Tube here About me I write about topics that my podcast guests bring to the podcast. They have years of experience with challenges and opportunities along the way, highs and lows and are in the thick of leading with purpose and passion, faults an'all. As a coach and trainer I work with leaders and their times to help them thrive, laugh, enjoy their work, be productive and to build teams of all ages.
We love what we do so we grow in that role, we end up as leader with people around us but we want to stay doing the thing we love doing. Balancing leadership is hard.
