Have you ever wondered if knowing too much about your subject could actually make you a less effective communicator? I know it sounds counterintuitive, but in this episode of Speaking With Confidence, I dive into why deep expertise might be your biggest liability when presenting and the one simple rule that can turn it all around.

Hi, I’m Tim Newman, a recovering college professor turned communication coach, and in this episode, I share my journey from thinking that piling on credentials and information would make me the most persuasive person in the room to realizing that too much expertise can actually get in the way of real communication. I know firsthand how easy it is to fall into “the expert trap,” and today, I want to walk you through the five ways this shows up in our presentations, plus the practical fix that anyone can use immediately.

It’s just me sharing hard-won experience and tools you can apply whether you’re presenting research, delivering a pitch, or leading a team meeting. We start by unpacking the subtle but powerful curse of knowledge, that cognitive bias that makes us forget what it felt like not to know our subject. From there, I break down the other traps that experts stumble into: overloading slides with data, defaulting to lecture mode, relying on jargon to “prove” credibility, and hiding behind an impenetrable expert persona that actually alienates your audience.

We don’t just name the problems, we walk through fixes. I share my go-to strategies, like building presentations that map the audience’s journey rather than just dumping information, making every slide a clear, focused compass rather than a wall of text, and applying what I call the “Gen Z Intern Test” to ensure your language stays human and relatable. Most importantly, I reveal the eighth-grade rule: If a typical eighth grader can’t grasp your main point and its importance after just one hearing, you need to simplify it even further. Clear ideas are your greatest source of authority.

Here’s what I cover in this episode:

The real ways expertise can sabotage your communication and connection

Understanding and overcoming the curse of knowledge

Escaping the trap of data drowning and cluttered slides

Breaking the lecture loop by building real exchanges with your audience

Avoiding jargon overload and speaking so anyone can understand

Letting go of the impenetrable expert persona and embracing authentic authority

The “eighth grade rule” as your universal test for clarity

Why preparing to connect is always more powerful than preparing to impress
