Why Experts Struggle to Communicate Clearly (And How to Fix It)

The biggest communication problem I encounter isn’t that people know too little. It’s that they know too much.
That might sound like a contradiction.
After more than 30 years as a journalist, BBC producer, interviewer and executive communication coach, I’ve worked with hundreds of specialists - scientists, doctors, lawyers, engineers, economists, senior executives and politicians.
One thing has become clear.
Being an expert and being a great communicator are two very different skills.
In fact, the deeper someone’s expertise, the harder communication can sometimes become.
Not because they can’t communicate, but because they forget what it’s like not to know.
Why experts struggle to communicate clearly
When you’ve spent years immersed in a subject, you naturally stop seeing where the difficult parts are.
You understand the terminology. You know the history. You understand the caveats, the exceptions and the nuances. You can make connections instantly because you’ve lived with the subject for years.
Your audience can’t.
That’s where communication often starts to break down.
Experts have a tendency to begin explaining something halfway through the story because everything that comes before feels obvious to them.
It isn’t.
The interviews that surprised me
People often assume the hardest interviews involve the most complicated subjects.
In my experience, that’s rarely been the case.
Some of the easiest interviews I’ve conducted have been with economists. Good economists spend much of their professional lives explaining complex ideas to people who aren’t economists. They understand that clarity matters just as much as accuracy.
Science and medicine can be very different.
Researchers are trained to communicate with precision. Every conclusion has a qualification. Every finding has a confidence level. Every statement has limitations.
Those are admirable qualities, and they’re essential in research.
They can also make it difficult to explain a subject clearly in a three-minute television interview or a ten-minute podcast.
Politicians present a different challenge altogether.
The problem is rarely that the subject is too complicated.
It’s often trying to establish what they actually think.
Every profession develops its own communication habits. The challenge is recognising when those habits no longer serve your audience.
Four mistakes I see time and again
1. Starting too far into the story
Experts often answer the question they think they’ve been asked rather than the question the audience is trying to answer.
People need context before detail.
If they don’t understand why something matters, they’re unlikely to remember the explanation that follows.
2. Assuming too much knowledge
Acronyms. Technical language. Industry jargon.
None of these are wrong.
But if your audience has to work hard to understand you, they’ll often stop listening.
Clear communication isn’t about sounding simpler.
It’s about making your expertise accessible.
3. Trying to say everything
Experts often worry about leaving something out.
Audiences worry about understanding what they’ve just heard.
Those are two very different concerns.
The best communicators know what to leave out without losing the meaning.
4. Forgetting the audience
One of the biggest lessons I learnt during my years at the BBC was that interviews are never really about the interviewee.
They’re about the audience.
The audience isn’t asking:
“Can this person demonstrate the full depth of their expertise?”
They’re asking:
“What does this mean for me?”
That’s a completely different question.
Simplicity isn’t dumbing down
Some experts worry that simplifying an explanation somehow weakens it.
I don’t believe that’s true.
The best communicators don’t remove complexity.
They organise it.
They know where to begin.
They know what to leave out.
Most importantly, they understand that communication isn’t about proving how much you know.
It’s about helping somebody else understand.
Three questions to ask before any interview
Whether you’re speaking to a journalist, appearing on a podcast, presenting to
investors or addressing clients, ask yourself three simple questions before you begin.
What does my audience already know?
What do they need to understand?
What’s the one thing I want them to remember?
If you can answer those questions first, your communication will almost always become clearer.
Final thoughts
Some of the smartest people I’ve ever interviewed have also been the hardest to understand.
Some of the clearest communicators weren’t necessarily the world’s greatest experts.
They simply understood something fundamental.
Communication isn’t measured by what you say.
It’s measured by what your audience understands.
