Why brain development is a lot more complicated than a number
The specific role of the frontal lobe
The early 2000s research that defined how we see brain development

Why does it suddenly feel like everyone has a diagnosis? From ADHD and autism to anxiety, trauma, burnout, and depression - mental health language is everywhere right now. But are rates actually rising? Or are more people finally being seen after years of being overlooked, misread, or excluded from the stereotype? In this episode, we unpack the psychology, politics, and culture of diagnosis: how diagnostic criteria have changed, why context matters, what social media has done to this conversation, and the tension between labels as affirming, or oversimplified.
We explore:
• What the data actually says about rising diagnosis rates
• Why historically missed groups are being recognised more now
• The role of context in shaping our experiences
• The risk of pathologising ordinary human struggle
• When scepticism is useful - and why it should be aimed at systems, not individuals
• Why a label can still be meaningful, helpful, and nobody else’s business

It can feel like the world - and our future - has never been more precarious or frightening. It’s a very normal response to feel anxious about it - and in many ways, being concerned is just a sign that you’re alive, switched on, and care about the what’s going on around you. But what happens when this anxiety becomes overwhelming, and we’re consumed by worry about the future? In this episode, we unpack:
• Why we’re prone to anticipatory anxiety in our 20s
• The evolutionary reasons for catastrophic thinking
• Why long-term anxiety rewires our brain
• When it’s healthy - and not healthy - to worry
• How to rebrand anxiety as excitement

It’s not a hot take to say that most of us are incredibly addicted to our phones. But when our usage bleeds into full-blown ‘technoference’ - technology interference - there can be significant, harmful consequences. In this episode, we explore how phones can harm our friendships and romantic relationships, including:
• How phones are replacing in-person interaction
• Why we can't help but be addicted
• The impact of 'phone snubbing' on our loved ones
• How phones are killing our sex lives
• The ways we can break our habits and find our way back to intimacy
