Always Know What You Don’t Know12/8/2025 Most business mistakes don’t come from ignorance. They come from assumptions disguised as knowledge. Back in the 1990s, my then employer, Ken Wrench — a highly respected professional pensions trustee and successful business owner — gave me a piece of advice I have never forgotten: "Always know what you don’t know." I smiled immediately. Not because it sounded like nonsense, but because I understood the paradox straight away. Ken knew I would.  He wasn’t encouraging uncertainty for its own sake. Quite the opposite. What he was really pointing to was something far more valuable: in business, awareness of your blind spots can be just as important as the knowledge you already hold. Over the years, I’ve come to believe that many business mistakes don’t begin with ignorance. They begin when people confuse what they know with what they think they know. And that difference can be costly. The Networking Moment Since that conversation in the 1990s, I’ve shared Ken’s line many times — particularly at business networking events. Interestingly, it tends to produce two very different reactions. Some people roll their eyes and dismiss it immediately. It sounds like a clever play on words, nothing more. Others lean in. They sense there’s something behind it worth exploring. In my experience, those who roll their eyes are often focused on projecting confidence. In business, there can be pressure to appear certain, even when certainty isn’t justified. Those who lean in are usually more comfortable with a different mindset: the recognition that growth often begins by acknowledging the limits of what we currently understand. KNOW vs THINK You Know This distinction sits at the heart of how I approach discovery sessions with clients at Future Point 4 Business, and with Enterprise Partners in AfricAspire™. When I ask questions, I’m not looking for what people think they know. I’m interested in what they can actually demonstrate they know. The difference is significant. What you know can be verified. It is supported by evidence. What you think you know is an assumption. And assumptions, when left untested, can quietly shape strategy in ways that no one notices until problems begin to appear. For many clients, making this distinction for the first time can feel slightly uncomfortable. But it’s also empowering, because it reveals something extremely useful: the gaps that matter most. Those gaps are often where the most valuable opportunities lie. Where This Matters Most One place this shows up clearly is in business planning — particularly in exercises like SWOT analysis. Strengths and weaknesses are usually internal and relatively easy to identify. Opportunities and threats, however, sit outside the business. They depend on what we understand about markets, competitors, and customers. If those insights are based on what we merely think we know, rather than what we can verify, then the analysis quickly becomes guesswork rather than strategy. The same is true with competitor research. Many businesses only look at competitors superficially. But deeper questions can reveal far more: • Who are they truly appealing to? • What advantages do they hold? • Where are their vulnerabilities? • How do they behave when market pressure increases? Understanding these things in reality — rather than through assumption — can transform how a business positions itself. A Simple Exercise: The Clarity Gap If you’d like to try this idea in practice, here is a simple exercise. Take a current project or business plan and draw two columns on a sheet of paper. Label them: What I Know What I Think I Know In the first column, write only what can be supported by evidence. In the second column, write the assumptions. Then review the second list carefully. If something can be verified with evidence, move it into the “What I Know” column. For the remaining items, ask yourself: • Can I find this out? • Do I need expert help? • Should I test and learn? You may be surprised how many insights appear once you begin separating knowledge from assumption. This is where what I call the Clarity Gap becomes visible — the space between what we know and what we merely believe to be true. Closing Thought Ken’s line has stayed with me for decades because it captures something timeless about business thinking. In an age where information is everywhere, the real skill is not simply acquiring more of it. It is learning to distinguish between knowing and thinking you know. So next time you hear the phrase: "Always know what you don’t know." Don’t dismiss it as a paradox. Lean in. Because the space between knowledge and assumption is often where the most important business insights begin. A question worth asking yourself: What belief about your business might be sitting inside your own clarity gap — quietly shaping decisions without ever being tested?
