The great LinkedIn performance: When everyone sounds credible, who actually is?

The best personal brands have always been built on substance first. Let’s keep that order, writes Grant Wyatt.

Over recent years, there has been a meaningful shift in career advice. The conversation has moved from building your career to building your personal brand.

Share your insights. Tell your story. Find your niche. Show up consistently. Position yourself as a thought leader.

There is truth in it. Visibility and effective communication matter – if people don’t know your work exists, opportunities are inevitably harder to find.

But I can’t help feeling we’ve started drifting into something a little strange. Somewhere along the way, building a reputation became managing an image. Increasingly, professionals spend as much time shaping how they appear as they do improving what they actually contribute.

And artificial intelligence is now compounding that trend.

Corporate theatre

Open LinkedIn for five minutes, and you’ll see the pattern.

The platform is flooded with polished leadership lessons, carefully packaged vulnerability, AI-created infographics, inspirational career stories, and motivational frameworks. It’s all very articulate. Now, some of it is genuinely insightful, but a significant proportion of it feels disconnected.

The language is so polished, and the formatting and phrases are familiar. Read enough of it and you begin to feel like you’ve already read today’s post yesterday. The whole thing starts to feel a little... off.

We sense the manufactured authenticity, and we can often tell when a post has been optimised more for the algorithm than for advancing an original idea.

A bizarre world of human-assisted, AI-generated, thought leadership.

Because AI is, by definition, a polished collection of what has already been said. Ideas already circulated. Patterns already recognised. Language already written. That’s incredibly useful for many tasks, but it shouldn’t become the ceiling for our own thinking.

The baseline we all feel

Why is this happening? Maybe because there is now an unspoken expectation that serious professionals should have a visible presence. Recruiters, clients, and future employers look. Whether we like it or not, our digital profile has become part of our professional identity.

Choosing not to participate can feel like voluntarily disappearing from the conversation. That’s the paradox of modern professional life. Most of us know parts of the game are performative, yet the baseline expectation means we’re all expected to play.

The problem isn’t LinkedIn. The problem isn’t even personal branding. The problem is that with AI in the mix, branding has become easier than becoming.

When A1 appearance becomes abundant

For most of history, looking knowledgeable required becoming knowledgeable first. Producing thoughtful writing, building frameworks, or communicating sophisticated ideas demanded years of accumulated experience and genuine intellectual effort. Presentation and capability generally moved together.

Today, almost anyone can produce an impressive article, a polished presentation or a compelling strategy document in minutes. AI has removed the barriers to appearing informed. The ability to sound intelligent is no longer a meaningful differentiator because the technology now gives that capability to almost everyone.

That changes the economics of professional credibility.

When everyone can create impressive-looking content, impressive-looking content loses much of its signalling value. Presentation and polish become abundant. Even intelligence begins to look abundant!

The scarce resource becomes something else: proof.

The coming credibility divide

I think this is where the next divide in professional careers will emerge.

On one side will be people who know how to signal credibility. On the other will be people who have actually earned it.

For years, these groups could be distinguished. A polished profile, strong communication skills and a confident presence could reasonably showcase underlying capability versus someone who couldn’t quite pull it off.

Increasingly, those signals are becoming less reliable because AI can manufacture many of them almost instantly. At least on paper.

Just ask any recruiter. Every résumé now mirrors the job advertisement almost perfectly. Funny that.

LinkedIn profiles have become increasingly slick. Years ago, poorly written profiles, spelling mistakes, or incomplete career histories often gave clues about someone’s substance or attention to detail. Today, AI smooths over those rough edges in seconds.

That doesn’t mean the person underneath has changed.

The things AI can’t fake

What AI cannot manufacture is consistent judgement and sound decision making.

It cannot build trust over years of delivering difficult outcomes. It cannot replace the credibility earned from solving complex problems, making sound decisions under pressure or leading people through uncertainty. It cannot replicate integrity, nor can it create the confidence that comes from repeatedly producing meaningful results.

These qualities have always mattered. AI makes them more important.

Ironically, the easier it becomes to create the appearance of expertise, the more valuable genuine expertise becomes.

Stop polishing, start building

That should change where we invest our energy.

Too many professionals are beginning to optimise for perception rather than contribution. They spend increasing amounts of time polishing their identity and less time strengthening the capability underneath. They become excellent at broadcasting knowledge while gradually spending less time acquiring it.

It’s a subtle trap because it creates the feeling of progress, even when very little professional growth is actually taking place. External validation becomes a substitute for internal development.

It’s performative. The danger is believing your own performance.

One of the risks emerging in an AI-augmented world is mistaking visibility for value, and the market will eventually expose the difference.

Businesses don’t ultimately reward beautifully written LinkedIn posts. They reward people who solve problems that others cannot. They reward judgement over noise, execution over intention, and trust over talk.

The professionals who create enduring careers will increasingly be those whose reputation is supported by evidence rather than just presentation.

• Can people rely on your judgement?
• Have you improved the organisations you’ve worked in?
• Do you consistently get better? Do you help others around you get better?
• Can you solve messy, ambiguous problems where there is no obvious answer?
• If nobody knew your name, would your work still stand on its own?

From personal brand to personal proof

None of this is an argument against personal branding. It is an argument for putting it back in its proper place.

A strong reputation should be the natural consequence of meaningful work, not a substitute for it. Visibility should amplify contribution, not compensate for its absence. The best personal brands have always been built on substance first. Let’s keep that order.

By all means, write. Share your thoughts. Build your network. Participate in the conversation because the reality is that modern professionals cannot afford to become invisible. But don’t confuse being seen with being valuable.

The professionals who thrive over the next decade will be those whose thinking consistently creates outcomes, whose judgement earns trust, and whose capability compounds faster than technology can commoditise it.

Looking credible has never been easier.

Being credible has never mattered more.

Success cannot be built on a strong personal brand alone.

It is built on something difficult to imitate: personal proof.
