466. How your environment programs your behaviour (and how to deprogram yourself)
05/10/2026 | 42 mins.How much of your behaviour is really “you” - and how much has been shaped by the environments around you? In this episode, we explore how childhood, relationships, social expectations, habits and physical spaces can influence the way we think, feel and behave. From nervous-system responses and beliefs about what is possible for us, to the people we pursue, the habits we repeat and the versions of ourselves that present in different places, we look at the psychology of how environments programme our behaviour.

● Impacts of childhood experiences on our nervous system
● Where our belief of what it possible or attainable comes from
● How relational environments shape our pursuit of love

See omnystudio.com/listener for privacy information. - From abusive MLM’s and wellness programs to doomsday sects and UFO religions, we’re all fascinated by cults. Their mystery offers us a way to explore the darkest recesses of human behaviour, while remaining seemingly out of their reach. But how do we actually define a cult?
Watch on Netflix: HERE
In this episode, we look at popular examples of cults, understand how they’re organised and recruit followers, and examine what makes some people so vulnerable to joining. We unpack:
• How a cult is defined, featuring the BITE model of authoritarian control
• What makes cult leaders so distinctive - and dangerous
• The (often surprising) tactics cults will employ to get people to join
• How people behave during and in the aftermath of leaving a cult
• Why there are cults all around us today, and people are still drawn to them

In this episode, we unpack:
• Why social media makes us compare ourselves with ‘the best’
• The figures behind what people in their 20s really have - and don’t
• How milestone anxiety and the social clock make us panic
• How we can reframe envy as a useful compass
• Why life circumstances mean we might have a different ‘starting line’ to other people
• Why you’re not delulu - things really are getting harder!
