01 / THE DISAPPEARING IDENTITY

The character
never changed.
Her face did.

An exploration of identity, representation, and the unexpected transformations of generative AI.

Enter the documentary
Bernadette, in the approved natural-texture portrait.

The story behind the faces

She began as a character.She became a question.

Created to help rebuild a career after a brain injury, Bernadette was meant to have one consistent identity. But as the technology evolved, her appearance began to change.

What was shaping the face that emerged?

One character.
Many faces.

I created Bernadette to help me return to the workforce after a brain injury.

As I learned to use artificial intelligence, Bernadette became my way of exploring new opportunities, developing skills, and rebuilding my professional future.

I had carefully chosen her appearance. She was meant to be one recognizable woman, with a consistent identity across the images and videos I created.

But something unexpected happened.

The more I worked with AI, the less Bernadette looked like Bernadette.

Her facial features, proportions, and sometimes her skin tone changed. Some differences were subtle. Others were so significant that she appeared to be an entirely different person.

I spent hundreds of generations trying to maintain her appearance, correcting individual images without realizing how far she had drifted from the original.

The problem persisted.

And eventually, I began asking a different question.

If AI couldn't consistently preserve the identity of one fictional woman, what did that reveal about the way these systems represent people?

That question became Bias Mirror.

One identity. Hundreds of generations. A question that extends far beyond one character.

03 / THE INVISIBLE BIAS

The technology learns.
So do the prejudices.

Artificial intelligence is often described as objective. But AI systems are built using data, decisions, and assumptions shaped by human society.

When that information contains stereotypes, unequal representation, or historical discrimination, AI can reproduce and sometimes amplify those patterns.

The consequences extend far beyond a generated image.

01

Race & Representation

When technology doesn't see everyone equally.

Research has documented substantial differences in the accuracy of facial-analysis systems across skin-tone and gender groups. These findings raise important questions about fairness and representation.

02

Gender & Opportunity

When yesterday's stereotypes shape tomorrow's possibilities.

AI-generated images can reinforce occupational stereotypes, underrepresenting women in traditionally male-dominated professions.

03

Age & Visibility

When experience becomes invisible.

Research shows that online media and language models can reinforce associations between women and youth, with implications for professional evaluations.

THE EVIDENCE / PUBLISHED RESEARCH

Nearly1.4 millionImages and videos examined in research on age and gender representation.Nature, 2025
Research context

Researchers examined nearly 1.4 million online images and videos and nine language models, finding women represented or associated with younger ages than men. The language-model analysis primarily examined embeddings. Separate ChatGPT audits found age-related gender bias in fictional résumé generation and evaluations. This was not a test of image generators or actual hiring outcomes.

Different technologies, not a claim about every AI system. These studies do not establish the cause of Bernadette's changing appearance.

THE HUMAN CONSEQUENCES

A biased image is not
always just an image.

When AI influences how people are represented, described, or evaluated, the consequences can reach beyond the screen.

Bernadette's changing face was where my questions began.

Bias Mirror is where those questions become an investigation.

Who is represented? Who is overlooked?
And who gets to decide what is accurate?
