When Knowing Too Much Gets in the Way: The Expert Blindspot

Imagine sitting in a classroom or a meeting, and someone asks if there are any questions. You have one– a big one– but looking around, everyone else shakes their heads. So, you stay quiet. You tell yourself you will figure it out later. You do not want to be the person who slows everything down, or worse, the person who does not know something that apparently everyone else already knows. Or perhaps you are filling out a university Qualtrics survey from your department. Simple enough, until you discover a slew of abbreviations: AY, FTE, FERPA. You stare at the screen. You do not want to submit something incorrectly, so you walk down the hall to ask a colleague. They glance at you and say, “Oh, AY is just academic year,” like it is the most natural thing in the world. You smile and nod, quietly wondering how many other things everyone else seems to already know that nobody ever thought to tell you.

This feeling of being on the outside of a language everyone else seems to speak is not a sign that you do not belong. It is often a sign of something that lives not in the student but in the expert standing at the front of the room. This exemplifies a concept from cognitive psychology called the curse of knowledge. Camerer et al. (1989) described it as a bias where knowing something makes it genuinely difficult to imagine someone else not knowing it. In simpler terms, the more expert one becomes in a subject, the harder it is to remember what confusion once felt like. This is what we are calling the expert blindspot, and it is one of the most quietly damaging forces in education today.

Mechanics of the Expert Blindspot

First, it is important to note that the issue is not due to bad teachers or uncaring professors. Most educators enter their classrooms with a genuine investment in their students. But good intentions do not close the gap between what an expert assumes and what a learner actually needs. Bransford et al. (2000) noted that experts organize knowledge in deep, connected patterns that make retrieval fast but explanation harder, because the mental scaffolding that once held those patterns together has long since been removed. The expert no longer sees the steps. They only see the destination. Some will argue that it is the student’s responsibility to advocate for themselves. While this is true, there is a meaningful difference between struggling with genuinely hard content and struggling because an explanation assumes prior knowledge. One is a challenge worth meeting. The other is a door never opened.

The expert blindspot does not always announce itself. Imagine how a global positioning system (GPS) functions. When driving, the user relies on every turn called out, every street name, and every distance marker. But upon driving the same route several times, one stops attending to the instructions. Imagine being asked to give someone directions using your usual route. You may accidentally skip a turn here or there because they seemed obvious. That is exactly what happens in the classroom. The route has become so automatic that the expert no longer remembers which turns a first-time driver actually needs.

Consider an international student sitting in a classroom. The professor is explaining a concept the student has encountered before, but under a different name– the way it was framed back home. The student raises a hand and uses the term they know. The professor pauses and says, “You don’t even know this?” The room goes quiet. The student shrinks into their seat and does not raise their hand again for the rest of the semester. That moment is not just embarrassing, it is academically costly. The professor did not see the student drawing from a different but valid framework. They saw a deficit and responded from the assumption that there was only one legitimate way to arrive at knowledge.

The blindspot is not always visible. Sometimes it is a syllabus built entirely out of field-specific shorthand with no glossary in sight. Sometimes it is a peer tutor who genuinely wants to help but begins every explanation at their own level rather than the level of their peers. Feltovich et al. (2006) observed that experts often fail to recognize the complexity beginners experience precisely because their own processing of that complexity has become entirely automatic. The difficulty lurks, invisible to the expert. The expert blindspot does not just confuse students. Over time, it convinces them they are the problem. When an explanation moves too quickly, and everyone else seems to be keeping up, the natural human conclusion is that something is wrong with you. Not with the explanation or the gap between what was assumed and what you actually knew. That conclusion, repeated across enough classrooms and enough semesters, hardens into something much more difficult to dislodge. It becomes an identity. “I’m just not a research person,” “I don’t have the mind for this,” and “Maybe I don’t belong here.”

What other fields would tolerate the cost of communication failure, while blaming the person who needed clear communication? If a pharmacist provided instructions that a patient could not follow and the patient suffered for it, we would not say the patient should have known better! We would ask whether the instructions were clear. Higher education deserves the same scrutiny. When a student falls behind, disengages, or quietly disappears from a program, the question is not, “What was wrong with the student?” The honest question is, “Where did we fail?”

Critics will argue that rigorous academic programs are supposed to demand a great deal from students and that scaffolding every concept endlessly would water down the discipline. While such concerns are legitimate, there is a difference between the difficulty of content and taking time for explanation. Students deserve to struggle with the former rather than becoming quiet casualties of the latter.

Recommendations for Addressing the Expert Blindspot

Thankfully, the expert blindspot can be addressed by both teachers and students in the classroom in the following ways: 

For faculty and instructors:

• Start with the learner in mind. Faculty can begin by intentionally using backward design (Wiggins & McTighe, 2005; Childre et al., 2009). That is, beginning with what students should know and be able to do, and then working backward to build the activities and materials that get them there. Rather than opening a lesson from their current understanding, conduct the lesson from a beginner’s mindset and design instruction that both anticipates a beginner’s perspective and intentionally builds on students’ prior knowledge. 

• Replace the phrase, “Any questions?” with something that actually works. Faculty can also move beyond the hollow ritual of asking, “Any questions?” which seldom produces responses, and instead build structured moments where students share their understanding of a concept or term. Confusion spoken aloud becomes a teachable moment. Confusion swallowed in silence becomes a gap that quietly widens over time.

• Bring in a near peer. There is something powerful about bringing in a student who recently mastered the concept to explain it alongside the professor. Someone two steps ahead of a beginner often communicates more usefully than someone twenty steps ahead, because they still remember the relatively recent learning curve. Instructors should also consider reviewing their teaching materials through fresh eyes or have a colleague review them to add a simple glossary where jargon appears. 

For Students:

• Call for prior knowledge as an entry point. Rather than saying, “I don’t understand,” which can feel exposing, asking, “Can you take me back to where this started?” invites the expert to rewind without putting either person on the spot. It also often provides a much more useful explanation. 

• Seek multiple explanations. Seeking explanations from multiple sources is not a sign of weakness, it is a smart learning strategy. If something does not click the first time, looking for a second or third way to encounter it using a textbook, a YouTube video, or a classmate’s notes might offer perspectives from different angles. 

•  Practice metacognitive transparency. Naming confusion out loud in a room full of quietly nodding heads is a small act of courage that almost always reveals that others were lost too. Expert blindspots survive in silence; by asking honest questions, we can dismantle them.

Conclusion 

Knowing something deeply and being able to bring someone else into that knowledge are two genuinely different skills, and the gap between them is where many students get lost. The best educators are not necessarily the ones who know the most. They are the ones who have stayed tender towards the experience of not knowing, who continue asking whether the bridge they are building is one their students can actually cross. To every student who has ever sat quietly confused, performing an understanding they did not have, that silence was never proof of not belonging. It was proof that the bridge had not yet been built. And to every professor, peer tutor, mentor, leader, and colleague who genuinely wants to reach their students, peers, mentees, colleagues, and novice professionals, the place to start is not with more content. It is with the honest memory of what it felt like to not yet know.
