Behaviour Change Scientist on ADHD & Addiction: Shahroo Izadi
The Hidden 20%
Changing minds by changing behaviour
Shahroo recommends altering behaviour first to shift beliefs, then showing economic and productivity gains to persuade policy.
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.

The Hidden 20% is a charity founded by AuDHD entrepreneur, Ben Branson.
Our mission is simple: To change how the world sees neurodivergence.
No more stigma. No more shame. No more silence.
1 in 5 people are neurodivergent. That’s 1.6 billion of us - yet too many are still excluded, misunderstood, or left without support.
To break the cycle, we amplify voices, challenge myths, and keep showing up. Spotlighting stories, stats and hard truths. Smashing stereotypes through honest voices, creative campaigns and research that can’t be ignored.Every month, over 50,000 people turn to The Hidden 20% to feel safe, seen and to learn about brilliant brains.
With your support, we can reach further, grow louder, and keep fighting for the 1 in 5 who deserve more.
