How the Curse of Knowledge Sabotages Communication in Rugby, Business, and Beyond
Some of the most intelligent, experienced people in the world are terrible communicators. Not because they lack insight or vision – but because they’ve forgotten what it’s like not to know what they know. This psychological blind spot is called the Curse of Knowledge, and it undermines clarity, cohesion, and leadership in nearly every high-performance environment.
In cognitive science, the Curse of Knowledge is a bias that occurs when a person communicating with others unknowingly assumes that the others have the background to understand. In practice, this means glossing over crucial context, relying on insider language, or misjudging how difficult something actually is. It’s not malicious – it’s human. But if you’re a coach, teacher, manager, or strategist, failing to account for it is a leadership liability.
🏉 Case Study: The Rugby Pitch
Rugby offers a powerful live-action illustration of the Curse of Knowledge. Imagine a university or academy fly-half shouting: “Let’s swing back off 10, punch the seam, then reload through the pod!” To a seasoned forward pack, that instruction lands. But to a newly promoted U18 player – or even a senior prop who missed that week’s walkthrough – it may as well be a foreign language.
At the elite level, terms like “folding,” “pinch-in,” “shooting off the edge,” or “backdoor option” become second nature. But in reality, these are constructed systems that require learning. Coaches and playmakers immersed in the system can forget that not every player has internalized the same visual cues, tactical frameworks, or decision trees. When young players hesitate or make poor reads, it’s often not due to lack of effort – but lack of shared understanding.
And when confusion turns into benchings, performance anxiety, or silent locker rooms, you’re not dealing with an effort problem. You’re dealing with the fallout of the Curse of Knowledge.
💼 Same Game, Different Field: The Corporate Boardroom
The same trap unfolds in offices and startups. Project managers who say, “We need to tighten our OKRs and track KPIs across all verticals” may sound strategic to their peers, but to new team members, it’s just a blizzard of undefined terms. A senior marketer assumes everyone knows the difference between ROAS and CTR. A data scientist presents dashboards without clarifying what “p-value” or “confidence intervals” mean. The result? Misalignment, lost trust, and disempowered teams.
In both rugby and business, performance depends on collective action. And collective action depends on shared language. Without it, feedback loops collapse. Teams hesitate. Individuals either fake understanding or withdraw entirely.
🎓 Even in Education: Professors and Parents Fall Into the Trap
Teachers are among the worst victims of the curse. A calculus instructor may skip vital steps when solving an integral because they’re obvious to them. A history professor assumes students grasp the geopolitical subtext of a Cold War reading. Parents tell teenagers to “just manage your time better” without ever modeling what that process looks like.
The Curse of Knowledge blinds experts to the cognitive load of beginners. It makes people believe they are being clear when they’re actually being opaque. Worse, it fosters impatience, frustration, and a damaging belief that the learner is at fault.
🔁 Escaping the Curse: Strategies for Coaches and Leaders
The good news? You can fight the Curse of Knowledge – if you have the humility to acknowledge it.
1. Assume less, ask more. Before giving instructions, check for understanding. Don’t ask, “Do you get it?” Ask, “Can you walk me through how you’d do it?”
2. Use analogies and stories. Abstract terms become tangible through relatable examples – on the field, in the office, or in the classroom.
3. Layer your communication. Great communicators deliver in levels: foundational idea, working model, technical execution. They don’t open with jargon.
4. Teach back. Have your team explain the concept back to you. This method reveals gaps quickly, and strengthens retention.
5. Revisit the basics often. High-performance environments are fast-moving. Don’t assume everyone remembers last week’s installation – or that new people even saw it.
🧠 The Leadership Lesson
The Curse of Knowledge isn’t a sign of arrogance. It’s the side effect of mastery. But mastery without empathy becomes noise. True leadership means remembering what it’s like to be new, confused, or on the edge of the system. It means designing environments where understanding isn’t assumed – it’s earned together.
On the pitch, that means explaining phase play in simple pictures. In the office, that means cutting through buzzwords. In life, it means meeting people where they are – not where you’ve already gone.
