Former Prime Minister Dame Jacinda Ardern Urges Leaders to Stop Fostering Public Division

Former New York and global leaders face a stark warning as former Prime Minister Dame Jacinda Ardern accuses politicians of worsening public mistrust and societal division during a speech at the Sydney Opera House.

The Sydney Address

Appearing alongside author Anna Funder at an event asking if people can disagree without dividing, Ardern stated that leaders currently make social tensions worse rather than better. She argued that globalisation created deep public insecurity over recent decades, leading to attacks on institutions like the World Trade Organisation. Rather than easing this anxiety, she said politicians offered simplistic answers like Brexit and blamed specific targets, which helped fuel figures like US President Donald Trump.

Social Media and Radicalisation

Ardern noted that entering Parliament in 2008 as its youngest sitting MP left her optimistic about online voter engagement, but her view changed drastically during the Christchurch mosque shootings. She described how a domestic terrorist was radicalised on YouTube and used Facebook to broadcast the attack to incite violence among other white supremacists, exposing the weaponisation of digital platforms. Furthermore, she pointed out that strong moral certainty in modern debates makes it hard to talk with opponents or solve problems.

Political Reactions

In response, National's finance spokesperson Nicola Willis criticised Ardern's comments on financial security during an interview on Ryan Bridge TODAY. Willis argued that it would have been helpful if Ardern had avoided tripling the country's debt and leaving behind a multi-billion dollar interest servicing bill while in office. Meanwhile, Ardern recently relocated her family to Sydney's northern beaches and secured a new role as a professor of practice in the School of Public Health at the University of Sydney.

Context

Public debates over political division and the role of digital platforms in spreading extremism have become central themes for many global leaders. Universities frequently appoint former public figures to professor of practice roles to share real-world policy experience with students through guest lectures and masterclasses.
