The instinct problem Most people running their own thing got started on gut feel. They saw an opportunity, trusted themselves, and went for it. That instinct is valuable. It is also, past a certain point, a liability. I have watched business owners make the same decision three times in a row, each time expecting different results, because they were going on feel rather than looking at what actually happened last time. The pattern is consistent: someone builds something that works, scales it a bit, and then starts making choices faster than they can track the outcomes. Instinct works when the stakes are low and you can course-correct quickly. It stops working when your decisions have a six-month lag before you see results, or when you are spending real money based on a hunch. Why evidence feels slow The objection I hear most often is that gathering evidence takes too long. People say they do not have time to analyse everything. They need to move. This is backwards. Evidence does not slow you down. Bad decisions slow you down. Reversing a wrong hire costs you three to six months. Launching a service nobody wants costs you the development time plus the opportunity cost of what you could have built instead. One client I worked with spent £14,000 on a marketing campaign because it "felt right" for the brand. It generated eleven leads. Eleven. They could have tested the concept for £500 first. The time you think you save by skipping analysis is time you spend later cleaning up the mess. Every time. What evidence actually means Evidence does not mean dashboards and data science. It means asking: what do I actually know, and what am I assuming? For most small businesses, evidence is simpler than you think. It is your last ten sales conversations. It is the three clients who left and why. It is the pattern in which services get repeat bookings versus one-offs. It is the difference between what you think your best marketing channel is and what the numbers say. You do not need sophisticated tools. You need the discipline to write things down and look at them before making the next call. The five questions Before any significant decision, I ask people to answer five questions in writing. Not in their head. On paper or in a document. First: what specifically are you deciding? Not the general area. The actual choice. "Should I hire a marketing person" is vague. "Should I hire a part-time content writer for £2,000 per month starting in August" is specific. Second: what evidence do you have that this will work? Not reasons it might work. Evidence from your own experience or data. Third: what evidence do you have that this will not work? Most people skip this one. That is exactly why it matters. Fourth: what would change your mind? If you cannot answer this, you have already decided and you are just looking for permission. Fifth: what is the smallest version of this you could test first? I use a version of this with the Decision Matrix tool at alira.london. It forces you to score options against criteria you set in advance, rather than rationalising whatever you already wanted to do. The instinct trap Here is what makes instinct dangerous: it feels like evidence. Your brain presents it as knowledge. You "know" this will work. You have a "feeling" about this person. That feeling is pattern recognition. Sometimes it is accurate. Often it is just familiarity. You have seen something like this before, so your brain assumes it will play out the same way. But your sample size is tiny, and you are not accounting for the times your instinct was wrong because you do not remember those as clearly. Ferrari just learned this the hard way. They launched an electric vehicle because they "knew" their brand could carry it. The backlash was immediate and brutal. People said it abandoned everything Ferrari stood for. The instinct that built the brand was not the right instinct for this decision. Evidence from their actual customer base might have told them something different. Building the habit You do not need to become a data analyst. You need to build three habits. First, write down predictions before you act. When you launch something, write down what you expect to happen. How many sales. What revenue. What response. Then compare reality to your prediction. This is how you calibrate your instincts over time. Second, run post-mortems on decisions that mattered. Not just failures. Successes too. What did you assume going in? What actually happened? What would you do differently? I have a 5 Whys tool at alira.london that helps with this. It forces you past the surface explanation into the actual cause. Third, separate the decision from the outcome. A good decision with a bad outcome is still a good decision. A bad decision with a good outcome is still a bad decision. Judge your process, not just your results. When instinct still matters I am not saying ignore your gut entirely. Instinct is useful for things that cannot be measured easily. Whether you trust someone. Whether a partnership feels right. Whether you actually want to do this. But instinct should be one input, not the whole decision. It gets a vote, not a veto. The people I have seen build something sustainable are the ones who learned to check their instincts against reality. Not constantly. Not obsessively. Just enough to catch the expensive mistakes before they happen. What to do this week Pick one decision you are currently weighing. Write out the five questions from earlier. Actually write them. Do not just think about them. See what you learn. Look at your last three significant decisions. What did you assume would happen? What actually happened? If you do not know the answer, that is the problem. Start a simple decision log. A spreadsheet is fine. Date, decision, expected outcome, actual outcome. Review it monthly. Within six months, you will know exactly where your instincts are reliable and where they are not.
