The Elizabeth Holmes Trap: Why Women Can't Just "Go Deeper"

What happens when leadership advice confuses authenticity with imitation?

A few years ago, leadership advice for women could often be summarised in a handful of instructions:

Lower your voice.
Speak more slowly.
Project gravitas.
Take up more space.

The logic seemed straightforward. Research showed that deeper voices were associated with leadership, authority and success. (We explored that research in our previous post, The Million Dollar Voice.)

So surely the answer was obvious?

If lower-pitched voices help leaders succeed, women should simply learn to speak in a lower register.

Except there is a problem.

The evidence suggests it doesn't work.

At least not in the way many people assume.

The Missing Piece

In 2022, researchers Midam Kim and Vincent Barker explored a fascinating question.

If lower-pitched voices increase perceptions of trustworthiness in male leaders, do they do the same for women?

The answer was unexpected.

Not really.

In a forced-choice study, listeners reliably judged lower-pitched male CEOs as more trustworthy. For female CEOs, the same vocal shift had a much weaker effect — and on some measures it all but vanished.

The very vocal characteristic associated with authority in men did not produce the same advantage for women.

Think about that for a moment.

For years, women have been told to adapt their voices to fit leadership expectations.

Yet those expectations appear to be different depending on who is speaking.

The issue isn't simply voice.

The issue is the listener.

Leadership Has a Soundtrack

Every society develops unconscious expectations about what leaders sound like.

Historically, most senior leaders were men.
Most politicians were men.
Most military leaders were men.
Most CEOs were men.

Over time, our brains quietly absorbed a pattern.

Without ever consciously deciding it, many of us learned to associate leadership with traditionally masculine vocal traits.

The result is a hidden bias.

When a man speaks with a lower pitch, listeners often interpret it as authority.

When a woman speaks with the same vocal qualities, listeners do not necessarily make the same judgement.

The signal is identical.

The interpretation changes.

That's not a communication issue.

That's a perception issue.

Enter Elizabeth Holmes

Few public figures illustrate this tension more vividly than Elizabeth Holmes.

The founder of Theranos became famous for many reasons.

One of them was her voice.

Observers frequently remarked on its unusually deep quality.

Following the collapse of Theranos, questions emerged about whether her lower register was entirely natural or consciously cultivated.

Only Elizabeth Holmes knows the full answer. And the wider lesson is more interesting than any one person's story.

Because when a leadership culture repeatedly signals that authority sounds a certain way, people adapt.

Some consciously. Some unconsciously.

They begin performing what they believe leadership should sound like.

And the danger, for any of us, is that performance can become disconnected from authenticity.

When that happens, communication becomes exhausting. The voice turns into a costume. A disguise, even. Certainly a performance.

The Real Cost of Vocal Performance

Most communication advice focuses on how people appear.

PowerVox is interested in what happens underneath.

Because maintaining an inauthentic communication style requires energy.

You have to remember the rules.
Monitor yourself constantly.
Suppress natural responses.
Manage how you are coming across.
Perform.

Many leaders know exactly what this feels like.

Not just women. Anyone who has ever felt pressure to fit an existing leadership mould.

The result is often a subtle but persistent tension between who you are and how you believe you should sound.

And people can hear that tension.

Perhaps not consciously. But they hear it.

Authenticity has acoustic fingerprints.

So does self-consciousness.

The Better Question

The question isn't:

"How can I sound more authoritative?"

The better question is:

"How can I communicate with greater intention?"

Because authority is only one dimension of effective communication.

Leadership also requires:

A leader who can only project authority is like a musician who can only play one note.

Eventually the audience stops listening.

Beyond Pitch

This is why PowerVox focuses on Voice Intelligence rather than vocal conformity.

Voice Intelligence is not about teaching people to sound the same.

It is about helping people develop range.

The ability to choose, in the moment, what to say and how to say it.
To understand how your voice affects others.
To recognise what a moment requires.
To communicate with intention rather than habit.

A powerful voice is not necessarily a deep voice.

A powerful voice is one that is aligned.

Aligned with your values.
Aligned with your message.
Aligned with the moment.

The Trap

The Elizabeth Holmes Trap is what happens when we confuse leadership with imitation.

When we assume the path to influence is becoming more like the people who already have power.

But history rarely moves forward that way.

Progress happens when we expand our understanding of what leadership can sound like.

Not when we narrow it.

The future of leadership communication isn't teaching more people to sound the same.

It's learning to recognise authority in more than one voice.

And perhaps that begins by stopping the search for the perfect leadership voice — and understanding the power of developing our own. Being courageous enough to use our own unique voice in the rooms that matter.

That is the work.
