Before I answer that, let me explain why every NLP intervention needs a “control”, and what science teaches us about measuring change… In science, nothing is taken at face value. If you want to know whether something works, you don’t just test it — you compare it. You measure it against a control. A control is the baseline, the “normal,” the standard set of conditions you already understand. Without it, an experiment becomes guesswork. You might get a result, but you have no idea whether that result is meaningful. And this principle applies far beyond laboratories and test tubes. It applies directly to NLP, personal change work, and the question people love to ask: “Does NLP actually work?” Let’s break this down. The Science Analogy: Why Controls Matter Imagine I’m testing a new polymer additive in asphalt in my business (MacRebur Limited). I want to know whether a new additive improves strength, flexibility, durability — whatever my goal is. So I create two samples: • Control asphalt — the standard mix that’s always used • Experimental asphalt — the same mix, but with my polymer additive included I test both to a set of criteria and standard. I compare the results. If the polymer works, my experimental asphalt should outperform the control. If I didn’t have the control asphalt, I’d have no idea whether the polymer made any difference at all. Maybe the asphalt was always that strong. Maybe it was always that weak. Without comparison, the experiment is pointless. NLP Works the Same Way… When we use NLP tools — anchoring, reframing, submodalities, timeline work, language patterns — we are essentially running an experiment on human experience. But here’s the key: You cannot measure change unless you know what the experience was before the intervention. This is why NLP questions often presuppose comparison: • “How do you feel differently now, compared to before?” • “What’s different?” • “What’s changed?” • “What’s shifted?” These questions aren’t fluffy. They’re the NLP version of a scientific control.

Eighteen years ago, Kate and I travelled to Kerala, India for a course that changed far more than our professional lives… One afternoon, we visited the SOS Children’s Village to model the excellence of the team running it. While we were having tea, a young girl - 9 years old, sweeping the courtyard - walked over, smiled, and said: “Hello auntie, hello uncle.” In that moment, Sughandy walked straight into our hearts. We decided that day to sponsor her, support her education, and make sure she had everything she needed. Letters turned into phone calls, phone calls turned into video chats, and every year I travelled back to India to visit her. She worked hard, qualified as a nurse, and a few years ago moved to Galway, Ireland to work as a carer. There, she met a young man who she’ll be marrying this Saturday. This week, Kate, India, Keira and I will travel to India to give her away, the only four members of her family among 200 guests from her new husband’s side. I’ll share our journey here, on Instagram and Facebook. This is more than a trip. It’s the continuation of a promise we made 18 years ago.

What if the opposite of my most negative thoughts or assumptions is actually true? What would change in my current mood?

Ask most people how their business is performing, their fitness routine is going, or their finances are looking, and you'll get a considered answer. Ask them how their mindset is doing, and you'll often get a shrug. We've been taught to measure almost everything about our lives except the one thing that filters how we experience all of it - our own thinking. That gap is starting to show. Nearly a third of UK employees say they've experienced anxiety or depression in the past year, and a further quarter report stress or burnout (Simplyhealth). Ninety-one per cent of UK adults say they've felt high or extreme stress in the last twelve months, and one in five workers has had to take time off because of it (Mental Health UK's Burnout Report 2026). Mental ill health is now the single biggest cause of long-term sickness absence in the country, responsible for 22.1 million lost working days a year and an estimated £51–57 billion cost to UK employers (HSE; Deloitte, via Time to Talk Hub). These aren't abstract figures. They're colleagues, friends, and, if we're honest, moments we've all lived through ourselves… The system tends to treat mindset as something you either "have" or don't, rather than a skill you can train. That's where I think we've got it backwards. Mindset is trainable, not fixed... Neuro-Linguistic Programming, or NLP, starts from a simple but powerful premise: the way we think, the language we use internally and externally, and the patterns we repeat all shape the results we get in life. Change the pattern, and you change the outcome. It's less about positive thinking and more about noticing the automatic loops - the self-talk, the assumptions, the "programmes" that quietly run in the background of every decision, relationship, and reaction we have.
