Why Average Minds Excel in Business — And What That Means for You

Overview

There is a stubborn myth in business that only the brilliant succeed. That you need to be the sharpest mind in the room to build something meaningful. But if you look at the actual data and the real stories behind most successful entrepreneurs, something fascinating emerges: average minds do not just compete — they consistently outperform. And no, this is not motivational fluff. The research backs it up. The IQ Trap: When Being Too Smart Hurts A 2021 study published in Perspectives on Psychological Science by Brown and colleagues examined the relationship between cognitive ability and life outcomes. What they found surprised many: the benefits of intelligence follow a curve that eventually flattens and can even reverse in certain domains. In leadership and entrepreneurship specifically, people with extremely high IQs often struggled with decision paralysis, overthinking and an inability to connect with teams.

The detail

Think about that for a second. The very trait society tells you guarantees success can actually become a liability. Meanwhile, a landmark study from the Journal of Economics & Management Strategy (Hartog et al., 2010) found that entrepreneurs with moderate cognitive ability and strong social skills earned significantly higher returns than those who were intellectually gifted but socially average. The title of the paper says it all: "If You Are So Smart, Why Aren't You an Entrepreneur?" Emotional Intelligence Beats IQ in Business A 2021 meta-analysis in the Strategic Entrepreneurship Journal compared the effects of general mental ability (IQ) versus emotional intelligence (EQ) on entrepreneurial success. The findings were clear: EQ had a stronger correlation with venture performance, customer relationships and team management than IQ. This makes sense when you think about what running a business actually looks like day to day. You are not solving equations. You are negotiating with a difficult supplier at 7 AM, calming an anxious client at noon, motivating a tired team at 4 PM and making a financial decision you are not fully sure about at 8 PM. None of those moments require genius. They require patience, empathy, resilience and the willingness to act without perfect information. The "Good Enough" Advantage Here is something nobody talks about: people with average intelligence are often better at execution because they do not overthink. A study from Hanken School of Economics (Virtanen et al., 2023) on cognitive skills and entrepreneurship found that personality traits like conscientiousness and openness to experience were stronger predictors of entrepreneurial entry than pure cognitive ability.

What it means for you

In other words, the person who shows up every day, follows through on commitments and stays open to learning will beat the genius who keeps waiting for the perfect plan. I have seen this play out repeatedly here in Nairobi. Some of the most successful business owners I have worked with did not finish top of their class. But they had something the academic high-achievers often lacked — a bias toward action. They launched before they felt ready. They made mistakes fast, learned from them faster and kept moving. Why Grit Matters More Than Grades Angela Duckworth's research on grit — the combination of passion and perseverance — has shown that it predicts success more reliably than IQ across domains. Her studies found that individuals who scored high on grit were 31% more likely to achieve long-term goals than those who scored high on intelligence alone. In the Kenyan context, this resonates deeply. Many of the entrepreneurs driving our economy did not come from privileged academic backgrounds. They came from hustle. From market stalls in Gikomba, from small shops in Eastlands, from WhatsApp-based businesses that grew into real companies. What they had was not extraordinary intelligence — it was extraordinary persistence. The Social Capital Factor Research consistently shows that business success correlates more strongly with the size and quality of your network than with your individual brilliance. A study from M13 Ventures surveying over 200 founders found that 78% ranked emotional intelligence and relationship-building as more critical to their success than technical knowledge or IQ. Average minds tend to be better collaborators. They ask for help more readily. They build partnerships instead of trying to figure everything out alone. They listen more than they lecture. And in business, listening is a superpower.
