The Hidden 20%

In part one of this two-part conversation, neurobiologist and author of The Gendered Brain and The Lost Girls of Autism - recently awarded the British Psychological Society’s Popular Science Book Prize - Gina Rippon joins Ben to unpack what we really know, and don’t know, about the human brain.

From left-brain/right-brain myths to the rise of gendered brain science, Gina explains why many of the ideas we’ve grown up with simply don’t stand up to scrutiny. Drawing on decades of research, she explores how brains change across the lifespan, how experience actively shapes neural pathways, and why no two brains - neurodivergent or not - are ever the same.

They dive into alpha rhythms, brain plasticity, ageing, and the cultural bias baked into neuroscience, including why the idea of distinctly “male” and “female” brains has caused more confusion than clarity.

Comedian, presenter and creator Holly Morris joins Ben for a candid conversation about living with AuDHD, the hidden cost of masking, and why being “funny” is often a survival strategy rather than a personality trait.

Holly shares how her comedy career grew out of lifelong hyper-vigilance - constantly scanning rooms, people and conversations and how that same awareness fuels both her humour and her exhaustion. She opens up about navigating networking, friendships and online spaces as a neurodivergent adult, and why masking can feel automatic, ingrained, and hard to switch off.

They explore Holly’s later diagnoses of ADHD and autism, imposter syndrome, her experience of Emetophobia, and how her Autism and ADHD overlap and show up in daily life.

If you’ve ever felt socially switched on but internally depleted, this episode will feel quietly familiar.

Dr Renata Fialho is back in the green chair.

In this conversation, Renata and Ben pick up where they left off - this time with Renata sharing her own ADHD diagnosis, what it was like to receive it later in life, and how it has quietly reshaped both her inner world and her clinical work.

Together, they unpack the realities of autism and ADHD assessments across the NHS and private sector, why certain myths continue to circulate, and where Renata sees genuine potential for more thoughtful, humane practice.

Renata also shares why she’s joining The Hidden 20% as a clinical psychologist, her hopes for the direction of neurodiversity care, and reflections on her work at the intersection of neurodivergence and sport - including why swimming can be such a powerful regulator for ADHD nervous systems.

In this episode, Ben sits down with bestselling author, psychologist and behaviour change expert Shahroo Izadi for a deep, honest conversation about ADHD, addiction and how habits really form.

Diagnosed with ADHD later in life, Shahroo reflects on how years spent working in addiction services helped her make sense of her own impulsivity, shame cycles and coping strategies - long before she had the language for neurodivergence.

Together, Ben and Shahroo unpack why addiction is often misunderstood, how neurodivergent brains are especially vulnerable in a frictionless modern world, and why behaviour change isn’t about willpower or fixing yourself.

This is a compassionate, practical conversation about trust, self-belief and designing habits that work with your brain - not against it.

As another year closes, we’re taking a gentler approach to New Year’s thinking. In this special episode, Ben is joined by familiar voices from across the year and a hint of who’s to come in 2026 - as he sits down with clinicians, creators, advocates and friends of The Hidden 20% to talk about goals, not resolutions.

From Dr Renata Fialho to Shahroo Izadi, Céin McGillicuddy, Dr Alison Lennox, Dr Josephine Neale and Tony Lloyd, each guest reflects on what they’re carrying forward into 2026 and what they’re intentionally leaving behind.

Together, we unpack why “resolutions” can feel loaded, deficit-focused and unrealistic for neurodivergent brains, and why goals rooted in compassion, flexibility and self-trust tend to work better.

This is a calm, grounding end-of-year listen - focused less on fixing yourself, and more on meeting yourself where you are.

From all of us at The Hidden 20%, thank you for your support this year - we’ll see you in 2026. 🟢
