From prohibition to social media - what makes bans succeed ... or fail?From prohibition to social media - what makes bans succeed ... or fail?
All In The Mind
From the prohibition era in the US, to gun control in Australia, bans have been used throughout history to change behaviour. Sometimes they work, sometimes they don't. Sometimes, they lead to a whole lot of unintended consequences. With the social media ban for under-16’s taking effect this week, we uncover the three factors that can determine whether a ban is more likely to succeed or fail – and find out what the history of bans tells us about how effective this policy might be (or not). Plus – how solid is the research on the link between mental ill health and social media use?

Ever wondered why some bans work while others don't? This episode of 'All In The Mind' takes you on a historical journey from the prohibition era in the US to modern-day social media restrictions for under-16s in Australia. With insightful commentary from Dr Kate Harrison Brennan of The Sydney Policy Lab, the discussion highlights three key factors that determine a ban's success: public perception of harm, availability of alternatives, and how the ban is framed.
You'll hear about the unintended consequences of bans, like the black market boom post-prohibition, and the successful gun control laws in Australia. Dr Alexis Witten from The Black Dog Institute weighs in on the social media ban, highlighting the complexities of linking mental health with social media use. Through real-life anecdotes from teenagers and parents, this episode challenges us to think about how bans impact society and whether they truly offer freedom or just a temporary fix.
Are we protecting our youth or simply delaying the inevitable? Tune in to explore these pressing questions and more.
